https://wftwtx.com/2020/03/24/o6xsy5y General Atomics Aeronautical Systems has quietly rolled out its new Avenger unmanned combat aerial vehicle (UCAV) – formerly known as the Predator C – and completed its first three flights on April 4, 13 and 14.
https://www.schneiderannerl.at/6l45mgsdi While company officials are not calling it a stealthy aircraft, they will admit to a reduced radar signature. The 20-hour-endurance UCAV’s undeniably low-observable design offers clues about how it could be employed.
A weapons bay allows internal carriage of 500-pound bombs with GBU-38 Joint Direct Attack Munitions with GPS navigation and laser guidance kits attached. Given the aircraft’s 41-ft length – which will increase by at least two feet in the second test aircraft – the weapons bay appears to be 10-feet long.

The aircraft is designed to carry about 3,000 pounds of weapons and sensors. For an additional two hours of flying time, fuel tanks also can be installed in the weapons bay.
By Tramadol Online Uk A long, featureless underside further provides an ideal location for a sensor such as an all-weather, active electronically scanned array (AESA) radar. The wide-area surveillance system – to be provided by the U.S. Air Force – has yet to be defined. It would be carried by a specialized all-reconnaissance version of the Avenger.
The V-tail both deflects radar and shields infrared signature of the aircraft’s 4,800-pound thrust Pratt & Whitney Canada PW545B turbofan. Predator C has two all-flying tail surfaces that each have two servos for flight-control redundancy.
The hump-backed design of the aircraft offers room enough for a serpentine exhaust to prevent radar observation of the turbine. Pratt has been developing an S-shaped exhaust system that both offers protection from radar and cooling to reduce the infrared signature. The engine is expected to provide an airspeed of at least 400 knots, but company officials say envelope expansion tests may prove the speed to be “considerably greater”. The UCAV’s operational altitude would be up to 60,000 feet.

The cranked trailing edge provides the aerodynamic and structural benefits of a tapered wing and helps shield the engine inlet from radar. Other design elements, from nose to tail, help avoid radar cross-section hot spots that would be caused by a curved side.
Tramadol Order Uk The aircraft was designed from its inception so that the wing could be folded at the point where it cranks for storage in hangars or for aircraft carrier operations. The UCAV also comes with a tailhook, which suggests that carrier-related trials are planned.
The inner section of the cranked wing is deep, providing structural strength for carrier landings and generous fuel volume while maintaining a dry, folding outer wing.
