GA-ASI selects GKN to create fuel bladders for MQ-9B

GKN Aerospace has signed a development agreement with General Atomics Aeronautical Systems, Inc. (GA-ASI) covering the design, development and manufacture of fuel bladders for the MQ-9B Remotely Piloted Aircraft (RPA) system.

GKN Aerospace develops, builds and supplies an extensive range of advanced aerospace systems and components made by Additive Manufacturing (AM) and other innovative manufacturing technologies focused to reduce weight on the aircrafts.

GKN Aerospace will work in conjunction with GA-ASI to design and manufacture the fuel bladders at the GKN Aerospace facility in Tallassee, AlabamaStefan Svenson, vice president of GKN Aerospace Special Products Group said: “We look forward to working with GA-ASI to provide a vital fuel system solution for this long-endurance Predator B platform variant. We have been supplying fuel systems for many decades and for many airframe platforms and MQ-9B fully exploits all our recent advances in both manufacturing and materials technologies.”

The agreement covers the fuel bladder system for the first production aircraft slated for 2018, with a potential full contract value of USD 15M when the aircraft enters into service with NATO’s UAV AIRWORTHINESS REQUIREMENTS (defined in STANAG 4671). MQ-9B is a "Type-Certifiable" version of GA-ASI’s Predator® B product line. The target is to create fuel bladders in complex shapes that fully exploit all available space on the MQ-9B airframe, maximizing the fuel load capacity and platform endurance.

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.
