Low-cost approaches to UAV design using Additive Manufacturing


Unmanned Aerial Vehicle (UAV) platforms are of major interest to Defense, Government, and commercial industries. The ability to remotely control an aerial vehicle capable of surveillance, offensive and defensive maneuvering, reconnaissance, or numerous other applications without the need to put a human life in jeopardy is a major attraction to their use. Furthermore, there exists opportunities to make these airborne vehicles largely autonomous, further reducing the need for even remote human operators. However, for all of the significant advantages of UAVs, there is a significant negative: the cost of manufacture, and the cost of design. Due in part to the substantial amount of complex electronic equipment on board, UAVs become not only a design of aeronautics, but an experiment in energy conservation through optimization. A limited range of UAV power becomes a limiting factor of UAV application. The challenge becomes to optimize the size, weight, and aerodynamics of the UAV based on the application.

Trump may take a hard line with Pakistan


Even though the US Government was unable to defeat the Taliban with 100.000 troops in the country, apparently Trump thinks that by taking a harder line with Pakistan and sending a few thousand more troops to Afghanistan he is going to pressure the Taliban into making peace.

The result will probably be for Pakistan to create more difficulties for the US Government in Afghanistan and also a point blank refusal to allow any drone attacks, as a majority of the Pakistani public would support such a move. However, the United States claims that the Pakistani spy agency the Inter-Services Intelligence (ISI) has ties to the Haqqani network of militants who are thought to be responsible for some deadly attacks in Afghanistan. The Afghan Government too has accused Pakistan as giving safe haven to the militants. Pakistan Government denies this, as they have lost about 7.000 of its security forces and about 22.000 civilians as a result of militant activity since 2003.

There are some within the US Government and in various think tanks who do not consider Pakistan an ally at all:

  • The Pentagon designated the Haggani network that Pakistan is alleged to support, as "terrorist organization" in 2012.
  • Navy Admiral Mike Mullen, a top U.S. military officer, told the U.S. Congress in 2011 that the Haqqani net was a veritable arm of the Pakistani ISI.
  • David Sedney, who was Obama's deputy assistant secretary of defense for Afghanistan from 2009 to 2013, claims that Obama's attempt to make Pakistan a strategic partner failed miserably and said that it made Pakistan's behavior even worse.


But this appears very one-sided: Pakistan in effect allowed UAV attacks on its territory in the face of tremendous political opposition. It also eventually carried out military operations in the territories that were quite costly in casualties for their security forces.

The U.S. has given considerable aid to Pakistan since 2002: $33 billion and that included Coalition Support Funds (CSF) that is meant to reimburse allies that incurred costs in supporting counter-insurgency operations. Pakistan did incur heavy costs in its operations in conflicts with various militant groups in the tribal areas of north-west Pakistan. However, the U.S. argues that Pakistan has failed to take action against the Haqqani network and last year withheld $300 million in CSF funding to Pakistan. US officials say the Trump administration may do the same... But also warns that moves such as this would encourage China to invest even more than the $60 billion it has already invested in Pakistan.

India to Purchase 22 Predator


According to The Diplomat, the Indian Government had expressed interest in purchasing an unarmed naval variant of the Predator already before 2015. However, the United States rejected India’s request because the country was neither member of the Missile Technology Control Regime (MTCR) nor did it enjoy Major Defense Partner (MDP) status.

Now, the US Government has approved the deal, which is valued at over $2 billion. The deal, still pending congressional approval, would be the first such purchase by a country that is not a member of the NATO alliance. With these new UAVs, India seeks to protect its maritime assets, in particular in the Indian Ocean, and detect intrusions on a real-time basis.

Next to the threat of terrorism emerging from the maritime domain, India has been in particular concerned about the growing Chinese naval presence in the Indian Ocean.

Pakistan: JF-17 shoots down an iranian UAV


An Iranian UAV (Unmanned Aerial Vehicle) operating in Pakistan’s Parom area of Panjgur district was shot down by a Pakistan Air Force (PAF) JF-17 fighter.

Iran’s army chief recently warned that Tehran would strike militant safe havens inside Pakistanremarks that drew a strong protest from Islamabad─ after 10 Iranian border guards were killed by militants allegedly from across the border earlier this year.

It was unknown when the UAV was shot down but the wreckage was recovered by local security forces last monday. According official sources, the UAV was shot down by a JF-17 in the Parom area of Panjgur district after it ventured “deep inside Pakistani airspace” on a spying mission.

The JF-17 (Joint Fighter-17) can be used for aerial reconnaissance, ground attack and aircraft interception. Technically is a lightweight, single-engine, multi-role combat aircraft developed jointly by the PAC (Pakistan Aeronautical Complex) and the CAC (Chengdu Aircraft Corporation) of China.

China launches record-breaking UAV swarm


The China Electronics Technology Group Corporation (CETC) claims to have set a new record for the number of UAVs flying in a swarm, the state-owned Xinhua news agency quoted the corporation as saying.

The 11 June news report states that the swarm comprised 119 UAVs, breaking CETC's previous record swarm of 67 UAVs. Xinhua did not mention when or where the event took place.

The size of the mini UAV swarm is greater than that trialled by the USAF in October 2016 when three Boeing F/A-18 Hornet deployed a swarm of 103 Perdix micro UAVs, which the US DoD noted was one of the world's largest micro UAV swarms to date.

CETC published a video in 2016 of its fixed-wing UAV swarm prototype, which shows the UAVs in a coordinated launch from the ground. The corporation said that the UAVs were flying ad hoc networks, sensing and avoiding collision, and demonstrating autonomous group control.

A CETC engineer was quoted by Xinhua as saying that UAV swarms will become "a disruptive force" that will "change the rules of the game".

El CH-T4 podría amenazar los buques de la US Navy


China ha informado que el UAV solar Caihong-T4 (CH-T4) ha logrado volar por primera vez a una altitud de 20.000 metros, lo cual representa una importante amenaza para la US Navy ya que podría ser capaz de funcionar durante varios meses o incluso años gracias a la ausencia de nubes a esa altura.


De acuerdo con los expertos, el CH-T4 combina un gran tamaño (39 metros de envergadura) y un reducido peso (450-490 Kg), gracias a sus componentes de plástico y fibra de carbono. Puede alcanzar velocidades de hasta 201 km/h y planear a una altitud de hasta 19 kilómetros, lo cual le permite cubrir una superficie de hasta un millón de kilómetros cuadrados.


Todas estas capacidades del CH-T4 permiten al Ejército Popular de Liberación (PLA) poner en peligro a los portaaviones estadounidenses en el Pacífico, ya que permite obtener y proporcionar en tiempo real información de cada objetivo a sus misiles balísticos anti buques, más concretamente al DF-21D, más conocido como "Asesino de Portaaviones".

PSS Technology: ¿Safety or New World Order?


Aside from the privacy concerns associated with persistent aerial surveillance, there are also worries related to transparency: In Baltimore, Persistent Surveillance Systems (PSS) technology was flown over the city without elected officials (including the mayor), the state’s attorney, or members of the public being informed first. And in Miami-Dade county, the mayor wasn’t aware of Miami-Dade Police Department (MDPD) persistent aerial surveillance plans. 



Military equipment has a tendency to make its way from foreign battlefields into the hands of domestic law enforcement. This is a trend that can be useful in investigating crimes, but policies that protect privacy should be in place before snooping airplanes take to the sky, and the public as well as local officials should be informed about the surveillance tools police are using. Persistent Surveillance Systems (PSS), the Ohio-based company that made the sensor system deployed in Baltimore, uses technology originally designed for military operations in Iraq and AfghanistanThis kind of technology has prompted privacy concerns in others cities, with Baltimore being perhaps the most notable.

EU unveils plans to regulate small UAVs


According to IATA, 65 countries currently have rules for the use of small UAVs. And among EU countries, France is a pioneer: Government decrees already regulate UAV use and parliament has voted in a law coming into force next year that will punish users of UAVs flying over airports and other sensitive areas with fines or prison.


Current common European rules only cover UAVs weighing above 150 kilograms, but small UAVs can be used to deliver services in urban areas, collect data for a wide range of industries, inspect infrastructure, and aid farming. "UAVs mean innovation, new services for citizens, new business models and a huge potential for economic growth," EU Transport Minister Violeta Bulc said in a statement. "We need the EU to be in the driving seat and have a safe UAV services market up and running by 2019. The EU needs to take a leading role worldwide in developing the right framework for this market to flourish, by unleashing the benefits for key economic sectors." added.


The aim is to have the regulatory framework functioning by 2019, with basic services like registration and e-identification. The blueprint unveiled from the European Commission, the EU executive, covers allowing drones to operate in high density under the supervision of fleet operators. The Commission cited estimates that the drone services market could grow up to €127bn in the next few years, so the demand for regulation is increasing with the rising use of drones and the risk of collisions. The European Commission said it hopes negotiations involving the European Parliament and 28 member states will be completed by the end of the year as a key part of the process. The idea is to build a system similar to that of Air Traffic Management for manned aviation, that would supply information to allow UAVs to fly safely and avoid obstacles or collisions.


The International Air Transport Association (IATA), which sets global standards for the aviation industry, counted 856 cases worldwide between January 2013 and August 2015 of a UAV getting too close to a plane for comfort, so the International Civil Aviation Organization (ICAO) is trying to establish a global framework for the future use of UAVs. Fortunately, there have been no collisions to date, the European Aviation Safety Agency (EASA) reported in February.

Airbus to implement UAVs at their plants


Airbus has already demonstrated the use of Ascending TechnologiesFalcon 8 UAV with RealSense depth-sensing technology from Intel to visually inspect airliners. The manufacturer has said it will implement UAV inspections of the A350XWB widebody airliner this year.


As said, for the initial tests the company used a multi-rotor UAV supplied by Ascending Technologies, a German company that U.S. semiconductor manufacturer Intel acquired in early 2016. “Now it’s a manual system with people having to climb all over the plane,” Intel CEO Brian Krzanich told the Xponential 2017 conference in Dallas in May. “With Airbus we’ve developed a system that’s capable of doing inspections both on the tarmac or in the hangar. Airbus has developed additional software that allows you to do an airplane inspection, identify and geolocate defects, understand their size and dimensions, then push out a data report that allows you to go back and do a repair.”


The GRVC-CATEC team will implement a UAV-based tool delivery and locating system at Airbus Defence and Space’s Centro Bahía de Cádiz site in El Puerto de Santa Maria, Spain, early next year, said Antidio Viguria, head of CATEC’s avionics and unmanned systems department. The plant specializes in manufacturing carbon fiber components for programs including the A400M transport and A330 MRTT (Multi-Role Tanker Transport). It also produces fan cowl doors for the A320neo narrowbody airliner.

UAVs keep dropping drugs and porn into prisons


A new report from USA Today found that UAVs have been used more than a dozen times to fly contraband into federal prisons over the last five years, as scattered reports suggest the smuggling operations have proven popular.


Local news reports from not just the United States but around the world have brought other instances to light over the past few years. In 2014, police in Australia said a UAV was employed for a planned drug smuggling operation. Later that year, there was another incident in South Carolina, where a UAV crashed while attempting to deliver weed.


And the list goes on: in 2015, a UAV-delivered drug package sparked a fight in an Ohio facility. That year, in yet another incident, two people were arrested for trying to smuggle contraband using a UAVThe paper writes that Justice Department documents showed attempts to smuggle cellphones, drugs, and porn into the federal facilities, although the tally almost certainly undercounts possibly successful attempts, as well as smuggling done in state facilities.


Understandably, officials are now wondering what to do about the problem. In April, the United Kingdom announced a new squad dedicated to combating the issue. The US Bureau of Prisons, meanwhile, has posted requests for technology that could be used to stop UAVs near facilities. While it’s likely impossible to get a full count of incidents, it does seem clear that the smuggling operations can sometimes be lucrative. Prosecutors in one recent case said a smuggler had been making $6,000 per drop.

ExecuJet Adds UAV Services In Africa


ExecuJet has announced the addition of Unmanned Aerial Vehicle (UAV) services at its African facilities in Cape Town, Johannesburg and Lagos.


UAVs will form an integral part of ExecuJet's operations, enabling clients to carry out inspections, surveys, mapping and photography in greater detail. ExecuJet will be able to deploy UAVs to any location on the continent, as required by its customers.


Gavin Kiggen, Director, Aviation Africa, ExecuJet, says: "The market for drone technology in the commercial sector has been increasing in recent years and is expected to grow at a rate of 19%+ between 2017 and 2020, as the technology becomes more widely utilised. Whilst attending the Drone Con conference, it emerged from research done by Dr Roelof Botha that in South Africa, the drone market is expected to create 24,000+ jobs by as early as the end of 2018, contributing R2b+ to the economy. UAVs can be used in various ways, from wind turbine inspections and crop monitoring, to covering sporting events and filming for television and movies. Industry experts believe that Africa is one of the most progressive regions when it comes to drone technology."

UrbanBees, o cómo aprovechar la contaminación


En la naturaleza, las abejas buscan el néctar de las flores para producir miel en sus colmenas.


De la misma forma, UrbanBees pretende utilizar un enjambre de UAVs para recoger la contaminación atmosférica y llevarla a una base central.


Allí las partículas se convertirán en material de Impresión 3D, con el que se podrán fabricar utensilios diversos demandados por los agentes sociales.


En primer lugar, se utilizarán los diversos sensores de contaminación desplegados por las ciudades para detectar cuando el nivel de contaminación supera un cierto umbral.


Las partículas más dañinas son las denominadas “Particulate Matter” (PM), que tienen un tamaño menor de 10 micras. En caso de alcanzar un nivel de contaminación peligroso para la salud, los sensores envían una señal a la base central que contiene los UAVs.


A continuación, los UAVs serán enviados al lugar concreto para recoger la polución. El sistema de guiado se realizará tanto por ondas de radio como por autopiloto dentro del UAV, dependiendo de las condiciones meteorológicas o de ubicación del lugar.


Los UAVs llevarán instalados filtros que permitirán la recolección de las partículas contaminantes. La recolección de partículas contaminantes acaba cuando los UAVs deban volver a la base central para recargar la batería, o bien cuando el depósito cargado por el UAV para almacenar la polución se haya llenado.


En ese momento, el UAV regresa a la base para vaciar el depósito y obtener nueva bateria para salir de nuevo. Por último, las partículas contaminantes de tipo metálico se someten a un proceso de compactación a través del cual se transforman en material para Impresoras 3D. Los objetos fabricados mediante Impresión 3D serán destinados a satisfacer diversas necesidades sociales, como puede ser la producción de material escolar.

La cara y la cruz de pilotar un UAV armado


Discretos, furtivos, silenciosos... los UAVs armados han ido poco a poco ganando presencia hasta constituirse en ciertos casos en un elemento esencial de las Fuerzas Armadas, pues contribuyen a salvar muchas vidas inocentes en escenarios reales de guerra.


Desde luego sus pilotos no sufren mal de altura, ni su cuello se castiga con las maniobras de un caza, ni sufren daño alguno en caso de que el UAV sea derribado. Esto es de agradecer, pero no todo es agradable en su trabajo: Se pasan muchas horas encerrados en un contenedor, trabajando en penumbra, visualizando constantemente una pantalla que muestra en tiempo real imágenes del territorio enemigo.


En el contenedor se respira siempre la tensión: Con frecuencia, su trabajo consiste en sobrevolar un area y vigilar de manera constante una casa hasta que vean salir de ella a un individuo concreto al que deben liquidar... que podrá optar por deambular, o bien por meterse en un vehículo y emprender la marcha, sin ser consciente de que, mediante un aparato gris, que vuela a más de 3.000 metros de altura, alguien está observando cuidadosamente cada uno de sus movimientos en tiempo real, desde una base ubicada a bastante distancia y quizá en otro continente, al objeto de lanzarle un misil Hellfire en el momento más adecuado para liquidarlo sin causar daños colaterales.


Además de que para desarrollar ese trabajo los pilotos deben ser capaces de soportar una gran tensión y no perder la concentración, deben estar psicológicamente preparados para un día a día que muy probablemente empezará por salir de su casa y llevar a sus hijos al colegio, para acudir después a la base, pilotar un UAV armado, bombardear un objetivo y asegurarse de haber acabado con el enemigo, y volver a casa al finalizar su turno, quizá pasando por el supermercado. Nadie les felicitará públicamente por su trabajo, y nadie siquiera les agradecerá que continúan vivos gracias a su trabajo. Incluso algún periodista mal informado y/o algún político oportunista les calificará gratuitamente como asesinos. Algo difícil de asimilar. Pero ser soldado exige asumir y aguantar todo esto y mucho más: en la guerra, hay que comportarse como en la guerra.

US downs pro-Syria regime UAV


A US warplane shot down a pro-regime UAV in Syria on Thursday 9th after it fired at coalition forces, officials said, marking a new escalation of tensions in the war-torn country’s south. Although the weapon the UAV deployed had hit only dirt, the action was nevertheless “clearly meant” as an attack, as the UAV had fired on coalition forces patrolling outside the zone.

No one was hurt in the incident, which occurred near the coalition’s At-Tanaf garrison close to the Jordanian border, spokesman Colonel Ryan Dillon told Pentagon reporters, but the UAV "was armed and still had weapons on it when it was fired upon by US forces from an aircraft,” he said. “Regardless of what kind of drone it was, it fired upon our coalition forces, and therefore showed hostile intent, and it was perceived as a threat,"The UAV was about the same size as a MQ-1 Predator, and it was not immediately clear who owned the aircraft or whether it may have been Iranian.

IAF: female squadron commander "not far off"


According to the army, there has been a 5% increase in motivation –as measured by requests – of female recruits as compared to last year’s enlistment, and the army is expecting a spike in female combat recruits in 2017 which will see over 2,500 female combat soldiers enlisting, a senior IDF officer in the Manpower Directorate told the Jerusalem PostBut one of the main challenges for the next generation of pilots is to train for the next war which will be completely different than in the past. Female pilots need to be very strong mentally to finish their course and “overcome all obstacles that may be in front of you,” he said.



Not in vain, a recent Defense Ministry report by IDF Ombudsman, Yitzhak Brick, found a significant decrease in the motivation of women to serve in combat positions. According to Brick, there is a discrepancy between the expectations of soldiers and the reality they face once placed in operational battalions which led to the decrease in the motivation of fighters. However, the senior Manpower Directorate officer disagreed with the findings of the report, telling the Post that the motivation in female combat soldiers continues to increase as well as the need for them to fill positions that have opened up due to the shortening of army service. “There is a significant jump in the recruitment of women into combat roles, and this is all due to their motivation to serve in those positions,” he said, adding that 15% of women volunteer to serve as long as their male counterparts. “That’s something we didn’t see in previous years. We should have put women in these roles even if we didn’t shorten the service period,” he said, stressing that the army “gives them the opportunity and they succeed. With women enlisting in increasingly greater numbers for IDF combat positions, a female Israel Air Force squadron commander is not far off."

US Army y Raytheon demuestran la capacidad del Stinger contra UAVs


Dos FIM-92J Stinger han sido lanzados desde una plataforma de defensa aérea de bajo nivel, destruyendo con éxito dos UAVs Outlaw (MQM-170C) y otro UAV más pequeño cuya marca y modelo no han sido revelados.


El FIM-92J conserva la misma capacidad de ojiva de impacto directo del modelo E, pero se actualiza con una sección de fusibles de proximidad, equipado con detectores de proximidad y una antena desarrollada por Lockheed Martin que incorpora un nuevo motor de vuelo y cartuchos generadores de gas.


El FIM-92 Stinger es un misil tierra-aire rastreador infrarrojo fabricado por Raytheon Missile Systems, y entró en servicio en 1981. El misil Stinger básico ha sido hasta la fecha responsable de 270 naves derribadas confirmadas, la primera de ellas un FMA IA-58 Pucará durante la Guerra de las Malvinas.


El misil es lanzado por un pequeño motor de eyección que lo empuja a una distancia segura del operador antes de activar el motor principal de dos fases de combustible sólido el cual lo acelera a una velocidad máxima de Mach 2,2 (750 m/s). La cabeza de 3 kg actúa por impacto y tiene un temporizador de autodestrucción. Puede atacar naves aéreas a una distancia de 5.500 metros y alturas de 3.800 m. También puede ser lanzado desde un vehículo M-1097 Avenger entre otros. El misil mide 152 cm de longitud y 70 mm de diámetro con aletas de 100 mm. El misil por sí solo pesa 10,1 kg mientras que el lanzador armado con su proyectil pesa 15,2 kg.


“Esta demostración ha revelado los resultados del trabajo conjunto que el Ejército de Estados Unidos, Raytheon y Lockheed Martin han realizado para conseguir un efectivo sistema de protección capaz de alcanzar cualquier tipo de UAV mediante un misil Stinger, dijo Jack Elliot, Director de Programa de Stinger en Raytheon Missile Systems.
