Avenger (Predator C)
Company GAAS (General Atomics Aeronautical Systems) in 2009, the UAV conducted a thorough modernization Avenger. This excavation has long been the main developer of the major UAV US Army Predator type.
The company's management plans thus replace drone Broad Area Maritime, which is released in the year 2015. New UAV should have improved performance. In particular, it will make independent takeoff and landing on the deck of an aircraft carrier. The payload will allow him to carry aircraft guided bombs GBU-38 JDAM laser-guided. The length of the first prototype was 10 m, and the second is planned to increase by at least 0,5 m, which will increase the space for the payload to about 3 m.
If necessary, cover flaps payload can be dismantled, thus establishing a comfortable container with equipment for intelligence. BA Predator C, as well as its predecessor (Predator B) is designed to carry about 1000 kg of sensors and weapons. In cases where stealth function is not necessary, and weapons UAV performed outside the fuselage and wings. In addition, you can install additional fuel tanks in the fuselage, which will increase the flight time is two hours. The proportion of normal fuel distribution between the fuselage and wings - 50 / 50.
The initial capacity of the electrical system will be less on the Avenger 45 kilovolts, rather than the Predator B. The lower long side allows the UAV to the monitoring system of the type "AFAR". Air Force Representation Review provides intelligence system. At the bottom of the nasal drone installed all-weather radar (LYNX SAR), and on the production models present system ball EO / IR, which on a prototype developer is not installed. In addition, the designers have created a new slide-out system.
V-shaped vertical tail provides additional deviation of the radar radiation and reduces the infrared signature from motor exhausts. To achieve the best in-flight tail servo two were mounted. The design of the engine compartment humpback, which will increase space for snake exhaust. This eliminates the possibility of the radar monitoring of the engine. Also infrared signature of the UAV is reduced by the S-shaped air intake and cooling. Maximum speed - 740 km / h - provides engine Canada PW545B. But spent debugging tests showed that the engine is capable of more. Service ceiling for the drone was 18 km.
The wing and tail edges when viewed from above the UAV practically parallel. Rear curved edge of the wing increases the aerodynamic performance and structural advantages of the wedge parallel to the wing and protects from the radar hood. The curvature and thickness of the wing allowed the drone to reach a large laminar flow.
Proper division, which produces materials for controlling the optical, infrared and radar signatures, has solved the problem with the creation of communication crossing the radome on top of the nose. It is completely transparent to the frequency band Ku, which uses most of the aeronautical satellite systems.
Unmanned aircraft are designed in such a way that the transport or storage in the warehouses of the wings could collapse. In addition to the Air Force drone interested in the Navy, as its features and applications can solve a lot of problems. Especially for this aircraft set the stern hook and tested the take-off and landing on the deck of an aircraft carrier. To date, the first orders for the BA made the US Air Force and the UK.
Planting is carried out by the drone landing gear, the same as on a plane F-5. The mechanism works by using a laser altimeter and vertical indicators, which are displayed on the operator's screen. Hold the engine power down the landing is performed by moving the "slide" in the middle of the display. This system eliminates unnecessary vibrations caused by the effect of parallax.
Predator C was tested for the first time in the air in April 2009, as part of a test program, which was conducted two months. The new UAV is gradually began to displace the old version with the production. Funding for the new project the company carried out independently, and its size is almost twice exaggerated version of B.
