UAVs 4.0: ¿Making war easier?


The world is becoming saturated with UAVs, and the technology that underpins these systems is only expected to become more sophisticated.

Next-generation UAV technology (UAVs 4.0) now in development includes: 
  • Additive manufacturing for bulk production
  • Advanced materials for enhanced stealth and smaller size
  • Energy storage, solar powered systems and satellite-based communications
  • Automation, artificial intelligence and machine learning
Advances in AI (Artificial Intelligence) and machine learning could lead to small UAVs that communicate with each other as a cognitive hive mind with the capability to swarm targets, leaving kinetic air defenses with too many targets to engage.

At the same time, advances in nanotechnology could lead to UAVs that mimic birds or insects, such as the Black Hornet, which could be capable of stealthy, close-quarter audio, video and possibly even DNA-sample intelligence collection. More disruptively, these nano-UAVs could engage in highly targeted killings through the injection of poison or self-destruction.

Both software and hardware are at the core of UAVs 4.0 but the physical limitations inherent in hardware do not apply to software, which is more diffuse and rapidly adaptable: Programming UAVs to remain on a “leash,” following warfighters wherever they go, or with the ability to loiter over a designated area and automatically find, fix and engage threats on their own, has tactical implications for war, particularly in the urban battlefield of the future replete with infrastructure that provides concealment for enemy forces.

Last but not least: The introduction of armed UAVs permanently altered the modern battlefield, and new technological advances in UAV technology (UAV 4.0) could do it again: from advanced materials that allow UAVs to fly, roll, run or swim in less forgiving environments, to thinking software than makes them more independent, to stealth technology that renders them even less visible. On the positive side, the intelligence that UAVs provide helps focus lethality on the intended target and limit the risk of civilian casualties and friendly fire incidents. But on the negative side, non-state actors will be able to employ them as well, giving insurgents or terrorists an outsized advantage: “While small drones can be a hazard domestically, their threat to the warfighter is growing as well. Footage of weaponized drones being used by ISIS provides a disturbing glimpse into the group’s Tactics, Techniques and Procedures (TTPs), and the future of asymmetric warfare. We have seen ISIS-controlled drones drop precision bombs on compounds, destroy armor and kill soldiers. And as dangerous as they are now, the lethality of drones will only increase as other nations and non-state actors refine their technology and TTPs.” (Deborah Lee James, former Secretary of the U.S. Air Force)

¿New Hope for Mountain Rescues?


A student team at the prestigious University of Warwick School of Engineering in Coventry, England, has designed an UAV (Unmanned Aerial Vehicle) with the ability to deliver immediate aid and equipment to people in trouble, before a rescue team arrives.

The project’s design lead, Ed Barlow (who has since graduated), knew he had a large-format 3D printer at his disposal. And that meant the team could design and manufacture something different than existing UAVs for aid and supply drops, such as the drones US startup Zipline uses to deliver blood and plasma to Rwandan hospitals: “They all use an airframe that you can go and buy from a shop,” Barlow says. “We needed our own custom airframe, made specifically for long-distance flight with a heavy payload.”

Warwick Associate Professor of Engineering Simon Leigh, who specializes in Additive Manufacturing, guided Barlow’s team during the project. He knew they would 3D-print reusable molds of the UAV body parts and then use them to resin-infuse strong-yet-light carbon fiber to create the finished product. Leigh says it took about one month of continuous 3D printing to finish the molds. After that, infusing the carbon fiber proved a challenge, as well: “We used liquid-resin infusion, which is under the vacuum,” Barlow says. “You apply a vacuum to your carbon fiber on the mold, and then you inject resin into it under the vacuum. That’s generally done on a much bigger scale, with much easier geometric parts than we were using, so we had to invent a lot of really cool tools to do it.”

Why You Should Attend the Military Additive Manufacturing Summit
According to recent reports, the worldwide 3D printing industry is expected to grow to $12.8 Billion in 2018, and is projected to exceed $21 billion by 2020. Manufacturers across a broad spectrum of industries including automotive, aerospace, high tech, and medical products are all piloting and using 3D printing technologies today. However, the US Military is taking an extremely active role in implementing the unique set of tools that additive manufacturing has proven that it can offer to units in resource scarce environments operating under restricted time schedules.

Through the use of 3D printing solutions, the Military is able to enhance the maintenance and sustainment capabilities needed to reduce downtime; minimize the costs associated with having to purchase, transport, and store additional resources; offer more operational flexibility to leaders in the field of logistics; and provide units in remote locations with the ability to reduce the size of their supply chains becoming more self-sufficient and agile in isolated and contested environments.

Additionally, the latest innovation in this field is metal additive manufacturing. This is accomplished by taking a base material, usually in the form of a metal powder and using heat generated by lasers to build a form. Other materials are being explored for additive manufacturing as well. We are beginning to move beyond 3d printing only being extruded plastic polymers and the military is particularly interested in this. The Navy has taken the first steps to explore this technology and the other branches are engaged as well. This forum will offer additive manufacturing solution providers, members from Government, and leaders in academia the opportunity to hear from some of the US Military's most senior and qualified subject matter experts on the future role of additive manufacturing in the Defense industry.

Additive Manufacturing to improve MQ-9 Reaper


The U.S. Air Force Research Lab is looking at ways to retrofit servo cover caps with conformal antennas for a complementary effect in order to use Link 16, a military tactical data exchange network used by fourth-generation fighter jets such as F-15 Eagle and F-16 Fighting Falcon.

“The problem that we’re addressing through this program is that there’s a big need for Link 16 on the MQ-9,” said Dan Berrigan, lead researcher for Additive Manufacturing of functional materials at the lab.

“It currently doesn’t exist on the aircraft. Because of that, the current challenge is, how do you put an antenna on an existing aircraft without drilling holes, without modifying the outer mold line?” Through 3-D printing, engineers are creating servo covers —an actuator that controls the flaps on the MQ-9 Reaper— with antennas “printed directly onto the surface.”

U.S Army explores 3D printing UAVs on the frontline


The ARDEC (U.S Army Armament Research, Development and Engineering Center) has revealed its use of 3D Printing to create crucial functional parts for UAVs. Even more, the ARDEC engineers are researching the possibility of deploying a 3D Printing Laboratory onto the frontline to fabricate essential spare parts or tools to help in their missions.

Additive Manufacturing as a Challenge For New FAA Certification Approach


The first step towards the regulatory approval for use of Additive Manufacturing (AM) also known as 3D Manufacturing in aviation occurred when Dr. Michael Gorelik, FAA chief scientific and technical adviser for fatigue and damage tolerance, announced that a roadmap towards that eventuality has been created.

The FAA sent a draft version of its Additive Manufacturing Strategic Roadmap to the agency management team for evaluation and the document suggests production, certification, maintenance policies the agency aims to establish over the next seven to eight years.

Additive Manufacturing Trends In Aerospace


Aerospace is the industry that other industries look to for a glimpse at what’s on the horizon.

Aerospace has a long history of being an early adopter, innovator and investigator.

What this industry was doing decades ago has now become commonplace, almost pedestrian.

For example, the aerospace industry was the earliest adopter of carbon fiber, and it was the first to integrate CAD/CAM into its design process.

There are many other examples that show that trends in aerospace are predictors of future trends in manufacturing across all industries.

Industry 4.0 and the Evolution of Small, Smart, and Cheap Weapons


Dramatic improvements in Robotics, AI (Artificial Intelligence), AM (Additive Manufacturing, also known as 3D Printing), and Nanoenergetics are dramatically changing the character of conflict in all domains.

The convergence of these new and improving technologies is creating a massive increase in capabilities available to smaller and smaller political entities — extending even to the individual.

This increase provides smaller powers with capabilities that used to be the preserve of major powers. Moreover, these small, smart, and cheap weapons based on land, sea, or air may be able to dominate combat.

This new diffusion of power has major implications for the conduct of warfare and national strategy. Because even massive investment in mature technology leads to only incremental improvement in capabilities, the proliferation of many small and smart weapons may simply overwhelm a few exceptionally capable and complex systems.

The advances may force the United States to rethink its procurement plans, force structure, and force posture. The diffusion of power will also greatly complicate U.S. responses to various crises, reduce its ability to influence events with military force, and should require policymakers and military planners to thoughtfully consider future policies and strategy.

Application of Additive Manufacturing for Light-weight UAV Wing Structures


UAVs (Unmanned Aerial Vehicles) have been developed to perform various military and civilian applications.

The present research is motivated by the need to develop a fast adaptable UAV design technologies for agile, fuel efficient, and flexible structures that are capable of adapting and operating in any environments.

The objective of this research is to develop adaptive design technologies by investigating current design methods and knowledge of deployable technologies in the area of engineering design and manufacturing.

More specifically, this research seeks to identify one truss lattice with the optimal elastic performance for deployable UAV wing design according to the Hashin & Shtrikman theoretical bounds.

We propose three lattice designs - 3D Kagome structure, 3D Pyramidal structure and the 3D Hexagonal Diamond structure. The proposed lattice structure designs are fabricated using an Stratasys Objet350 3D Printer while the material chosen is a polypropylene-like photopolymer called Objet DurusWhite RGD430.

Based on compression testing, the proposed inflatable wing design will combine the advantages of compliant mechanisms and deployable structures to maximize flexibilities of movement in UAV design and development.

GKN Driveline expands deployment of 3D Printing solutions


‘As we continue to design parts specifically for additive manufacturing, we are finding more and more applications that are delivering value. In the future, I believe that FDM 3D printing will become an integral part of our entire tool development cycle and help us further improve business performance.’ says Carlo Cavallini, GKN lead process engineer.

GKN Driveline —an UK-based, multi-national driveline components supplier and division of global engineering company GKN is expanding deployment of Stratasys 3D printing solutions at its plant in Florence, Italy, thus replacing several traditional manufacturing processes. GKN Driveline serves over 90 percent of automotive manufacturers globally, including the Fiat Chrysler Automobiles Group as well as Ferrari and Maserati. Customer lead times are continuing to shorten and the plant in Florence identified several applications that 3D printing could be used for, facilitating an overall increase in productivity.

‘The ability to quickly 3D print tools and parts that are customized to a specific production need gives us a new level of flexibility and significantly reduces our supply chain,’ adds Cavallini, also team leader at the plant. ‘Considering that we produce several thousand, individual parts a week, this ability to manufacture on-demand is crucial to ensuring our production line is always operational and maintains business continuity.' The plant’s factory floor team is using the Fortus 450mc to produce complex assembly tools for the production line in almost 70 percent less time than it takes using traditional methods. This, in turn, has enabled the team to undertake feasibility analyses of the tools and start using them more quickly, therefore accelerating the overall production schedule.

The team also managed to print a bespoke end-of-arm tool that moves individual components from one point of the assembly line to the next. It is made from ULTEM 9085 high-performance 3D printing material and can therefore endure prolonged use, said to equal that of a like-for-like metal component. A number of 3D printed end-of-arm tools are now in use across production, significantly reducing production downtime. 3D printing is also being used to produce customized, on-demand replacement parts for manufacturing equipment. For instance, the team recently printed a missing cable bracket for a robot, saving a week on the time it would have taken for a supplier to deliver it and consequently accelerating the delivery of parts to customers.

The World’s Best Weaponized UAV Ever Built


Also known by the name of the Predator B, this is most probably, the world’s best weaponized UAV, judging by the amount of technology present inside it. 


Since it was released, it has managed to consolidate its place into the fleet of weaponized UAVs in use.


It includes a turboprop engine, which offers nine times the horsepower of the piston-driven power plant, thus allowing the UAV to carry 15 times the load of other models.


Not only this, but it can also deploy laser-guided bombs and shoot Hellfire missiles, directly against targets situated on the ground. The UAV has also been designed to use air-to-air missiles, meant to hit aerial targets. 

UAV Airstrike in Libya


An airstrike carried out on Tuesday 26th in Libya killed "several" fighters from the Islamic State group, also known as ISIS, according to a Thursday 28th statement from U.S. Africa Command. It followed a similar UAV attack last week that Trump personally approved, the first in Libya since the one President Barack Obama authorized in January the day before he stepped down from office.


As for whether the command could carry out strikes wherever it chooses in Africa, an official speaking on the condition of anonymity to discuss current operations says it limits its actions to pre-established agreements with partner countries. In this latest instance, AFRICOM coordinated with the de facto coalition governing Libya known as the Government of National Accord. It has similar arrangements with other partners in Africa, including with Somalia to hunt Islamic State group fighters and with others to combat piracy off the Horn of Africa and the Gulf of Guinea.


"These strikes were conducted under the Presidential Policy Guidance," Defense Department spokeswoman Army Maj. Audricia Harris says, referring to a 2014 document the Obama White House released explaining the policies that would govern covert war. "That allows for the use of all available tools of national power to protect the American people from threats posed by groups such as ISIS, al-Qaida and their associated forces."

China unveils its answer to the Reaper


After modifying it for certain missions, China has started commercial production of its deadliest UAV: an UAV named CH-5, able to fly for up to 120 hours, and that many experts believe it could be a rival to the Reaper. The initial output of this UAV will be relatively small: 10-20 units a year, and it is unlikely to exceed 20 due to the size and sophistication of the aircraft. Regarding weapons payload, this UAV can carry up to 16 air-to-ground missiles.


The CH-5 can be operated by an undergraduate student with basic knowledge of aviation after only one or two days of training, according to state media reports. This is because of the simplicity of its user interface, and the fact that operations like the take-off and landing can be automated. The UAV can also be modified to become a low-cost airborne early warning system, or equipped with high-tech sensors such as wall and ground-penetrating radars developed by China.


Summarizing: with the commercial production of the CH-5, China could be ready to offer international buyers a heavy military UAV with many features comparable to the General Atomics MQ-9 Reaper, but at around half the cost.

Additive manufacturing in UAVs: Challenges and potential


UAVs (Unmanned Aerial Vehicles) are gaining popularity due to their application in military, private and public sector, especially being attractive for fields where human operator is not required.

Light-weight UAVs are more desirable as they have better performance in terms of shorter take-off range and longer flight endurance. However, light weight structures with complex inner features are hard to fabricate using conventional manufacturing methods.

The ability to print complex inner structures directly without the need of a mould gives Additive Manufacturing (AM) an edge over conventional manufacturing. Recent development in composite and multi-material printing opens up new possibilities of printing lightweight structures and novel platforms like flapping wings with ease.

This paper explores the impact of additive manufacturing on aerodynamics, structures and materials used for UAVs. The review will discuss state-ofthe-art
AM technologies for UAVs through innovations in materials and structures and their advantages and limitations. The role of additive manufacturing to improve the performance of UAVs through smart material actuators and multi-functional structures will also be discussed.

Additive manufacturing techniques for millimeter-wave components


Additive Manufacturing technology has made significant advances in terms of materials, tolerances, and surface finishes.

The technique is becoming more common in science and industry. Since it has proven effective in constructing small parts with fine features, 3D Printing is well suited for improving upon the manufacturing processes of millimeter-wave components.

This paper explores the approach specifically applied to waveguide components produced using two different additive manufacturing approaches. Work is also being done to fabricate parts via additive manufacturing techniques in-house at General Atomics.

AUHSD Teams with Tesla Foundation for UAS Education


The Anaheim Union High School District (AUHSD) is the first public school district in the nation to partner with the Tesla Foundation to provide students with training to successfully work in the emerging technology field of unmanned aviation, or drones.

A nonprofit science and technology think tank, the Tesla Foundation is launching its initiative beginning at Magnolia High School with after-school programs featuring FAA (Federal Aviation Administration) approved curriculum, equipment, and Drone Flight Simulation Kits.

The foundation’s goal is to identify and develop a “farm system” of young talent that can be future innovators and entrepreneurs in the unmanned systems industry. “We are excited to partner with the District in this most critical endeavor,” said Keith Coleman, chief strategy officer of the foundation. “Our focus is looking at the future of jobs and the future of work. Automation and the disruption that it will bring is real, yet while jobs will be lost, there will be lots of new opportunities in the (new) field of aerial robotics. Through this partnership, we will help move the needle forward for underrepresented students who may not otherwise have a pathway to these experiences. The Tesla Foundation sees critical thinking and access to technology as the democratization of opportunity.”

Trustee Al Jabbar thanked Superintendent Mike Matsuda for making the connection that led to the partnership. He also thanked the Tesla Foundation for “recognizing that AUHSD is at the cutting edge in preparing students for the 21st Century workforce. Once parents and the community learn about how this partnership promotes innovation, creativity, and entrepreneurship in an emerging STEAM field, I know they will be as enthusiastic as we are.” The Tesla Foundation estimates that the economic impact of drones will be $82 billion within the first decade of their operational integration into the national airspace system. Drone industries leverage many key technologies, including cybersecurity, sensors, data analytics, aeronautics, aviation, Additive Manufacturing, precision agriculture, first responders, geospatial information, and simulation.

Marines take 3D printed UAVs from the lab to the field


Additive manufacturing is a technology the U.S. military has been pursuing for some time: “Imagine being in a forward deployed environment, and just like Amazon, you can ‘order’ the weapons and equipment you need for the next day’s mission from an entire catalog of possible solutions,” says Capt. Chris J. Wood, who oversees innovation efforts at the Marine Corps’ installations and logistics branch. “These solutions can all be upgraded literally overnight, in order to integrate new components or adapt to new requirements.”

In the coming weeks the service will deploy a tiny unmanned aircraft dubbed the “Nibbler,” which would become the first 3D printed drone used in combat operations by conventional forces. Marines see it as just the beginning of a new way of equipping and supplying forces in the field. The Nibbler will be used for surveillance missions, along with several other 3D printed unmanned aircraft that the Marines are still developing, Wood added. “We can have a backpack-able fixed wing UAS for long endurance ISR. We can have a small quadcopter for building clearing operations,” he said. “We will forward deploy these capabilities into a combat zone as soon as possible.”

Achieving ship's mission flexibility through designing, printing and operating unmanned systems with additive manufacturing and delayed differentiation


The Design, Print and Operate (DPO) Concept Of Operations (CONOPS) is proposed in this thesis as a new means of equipping ships with the appropriate capabilities. A companion concept of delayed differentiation is also introduced. In coupling the two concepts, Additive Manufacturing (AM) of capabilities in-situ becomes a possibility through the equipping of operational units with three building blocks: additive manufacturing systems and their raw materials, commercial off-the-shelf items and field programmable gate arrays.

A concept of operations on uses of additive manufacturing was developed to illustrate the flexibility that the nexus of DPO CONOPS and delayed differentiation can engender. A tactical UAV (Unmanned Aerial Vehicle) was used as an illustration to contextualize the concept of operations to enhance the littoral combat ship's survivability when operating in the littorals. Assessments were then made on the feasibility of DPO CONOPS for shipboard uses. A tactical UAV was used as it was assessed to be operationally relevant and significant. Analytical models that could be iterated to achieve the specific-to-mission requirements were developed to analyze and assess the implementation approach. The models focused on the UAV's reliability in fulfilling the mission as well as the build-time of the UAV.
