Barracuda: A brief look


Development on the EADS Barracuda fully-autonomous, medium-altitude, long-range UAV began in 2003, and is backed by both Germany and SpainDespite crashing during a 2006 test flight, which grounded the project for nearly two years, the Barracuda has since successfully completed more than a dozen test flights.


Barracuda is built from a mix of off the shelf components and custom hardware systems. Its entire fuselage — save for a pair of reinforcing wing spars — is composed of the same carbon fibre composite that covers the Eurofighter Typhoon. What’s more, the 8m long, 2.7-tonne demonstrator does almost entirely away with hydraulics — aside from the landing gear, the UAV operates entirely on electronic actuators. And while it isn’t as quick as the Taranis, the Barracuda reportedly packs a 14kN Pratt & Whitney jet turbine capable of achieving mach .85 with a 6000 m service ceiling and an estimated 200km operational radius.


For the foreseeable future, the Barracuda will remain a developmental test bed for future Cassian UAV technologies with hopes of eventually developing a system that can operate in unsegregated airspace alongside manned and civilian aircraft. And with both the nEUROn and Taranis gunning for deployment by the end of the decade, the skies over Europe are going to get crowded.

Turkey plans to equip Anka UAV with satcom capability


Turkey is planning to add satellite communication (SATCOM) capability to the domestically manufactured Anka unmanned aerial vehicle (UAV), Turkish Undersecretariat for Defense Industries (SSM) head Murad Bayar has revealed.


Bayar also informed that Turkish Engine Industries (TEI) has been ordered to develop an engine for the Anka after the original manufacturer, Avic International decided to abandon military business, and stopped deliveries in August. Anka manufacturer, Turkish Aerospace Industries (TAI) has previously ordered the Centurion engine for an initial batch of ten UAVs, but is now required to explore other options. ''Alternatively, we could consider an engine like Rotax, or modify an existing automobile engine for the Anka,'' Bayar noted, adding that the SSM is also very soon expected to sign a contract with TAI for acquisition of ten Anka systems for the Turkish Air Force.


Having completed acceptance tests in late January, the Anka medium altitude long endurance (MALE) UAV is designed for real-time image intelligence, surveillance, reconnaissance (ISR), target detection, recognition, identification and tracking missions.

Raytheon to provide MTS-B for the Reaper


Officials of the Air Force Life Cycle Management Center Medium Altitude Unmanned Aircraft Systems office at Wright-Patterson Air Force Base, Ohio, awarded Raytheon a $50.2 million contract to provide the Multispectral Targeting System (MTS)-B for the Reaper  UAV.

The contract calls for Raytheon to provide MTS-B turret units, 37 MTS HD electronics units, containers, spare parts, and support equipment. The MTS-B provides electro-optical, infrared, laser designation, and laser illumination packaged in one sensor package. The MTS-B uses a digital architecture to provide long-range surveillance, high-altitude target acquisition, tracking, rangefinding, and laser designation for the Hellfire missile and for all tri-service and NATO laser-guided munitions, Raytheon officials say.

A turreted or forward-looking pod combining several sensors, the MTS has visible-light and infrared full-motion video cameras for long-range surveillance. The systems offer multiple wavelength sensors; near-infrared and color TV cameras; target illuminators; eyesafe laser rangefinders; image merging; spot trackers; and other avionics. The system’s Advanced Targeting Forward Looking Infrared (ATFLIR) pod also is used with Paveway, JSOW, and HARM munitions. The MTS sensors carry the military designations of AAS-52, AAS-53, ASQ-228, DAS-1 and DAS-2.

UAVs Manufactured On the Fly


UAV Solutions Inc. in Jessup, Maryland, specializes in UAVs (Unmanned Aerial Vehicles) and UAV control systems.


The video above includes a flight demonstration of a UAV that was manufactured using Stratasys Fortus 400mc Production Systems. Typical applications of this vehicle include use by police departments, fire departments, and other emergency first responders, as well as military applications. According to company CEO Bill Davidson, when the company bought their first Stratasys 3D Printerthey thought that it was an impressive technology – but they didn’t really understand all that it could do.


While they originally figured they would use it to produce little prototypes or giveaways for their customers, FDM-based (Fused Deposition Modeling) 3D printing has now “crept” into every aspect of their manufacturing process. In particular, they found that the ULTEM™ 9085 resin material is particularly well-suited to aviation applications.


As flame retardant high performance material, ULTEM exhibits a high strength-to-weight ratio and FST (flame, smoke, and toxicity) rating which make it an excellent choice for the commercial transportation industry – especially aerospace, marine and ground vehicles. The FDM-based manufacturing process allows UAV Solutions to very rapidly make changes to the avionic structures, thereby enabling them to meet the high performance and precise demands of their customers. In fact, Davidson states that using the ULTEM 9085 allows them to manufacture components that could not be made with standard milling procedures.
