The Mi-24, Mi-25/35 « Hind » multipurpose combat helicopters are intended for destruction of armoured vehicles; low-speed air targets; enemy manpower; fire-support of land forces; delivery of technical troops; evacuation of the wounded; as well as for transporting some special-purpose loads.

The Brazilian pioneer was the first to demonstrate that controlled flight was possible thanks to his dirigible balloons. He flew his « Number 6 » round the Eiffel Tower as early as 1901. He designed and flew the 14-bis « Oiseau de proie » (Bird of prey) in 1906. This invention was the first fixed-wing flying machine witnessed by the European press and French aviation authorities to achieve an actual controlled flight.
He designed and flew the Demoiselle (Damselfly) in 1908. This aircraft was controlled by wing warping, and a tail unit equipped with a rudder, and an elevator.
The US Navy X-47B UCAS-D (Unmanned Combat Air System Demonstration) successfully completed its first flight at Edwards AFB on February 4, 2011.
The flight which was conducted by a US Navy/Northrop Grumman test team, lasted 29 minutes. The flight test was aimed to provide test data to check the system software for guidance and navigation, and the aerodynamic control of the tailless drone. The X-47B is deemed to safely take off from, and land on the deck of an aircraft carrier.
Other flight tests should be performed to validate the airworthiness of the drone in Naval Air Station Patuxent River (NAS Pax River), Maryland till 2013. Here is the maiden flight video:
The first J-20 BLACK EAGLE taxiing-test snapshots have popped up throughout the blogosphere for a few days. These so-called leaked pictures reveal a design that comes straight from the J-XX with the front part similar to the F-22 Raptor’s one, and the aft a bit like the Sukhoi PAK FA’s one.
Thanks to ChineseKungFu100, you can watch below a High-Definition video in which you can see a huge glass cockpit. It is believed that the J-20 is likely to be cheaper than the PAK FA / T-50, and far cheaper than the JSF F-35 and the F-22, with lower performance though longer radius of combat, and bigger strike capability. The shapes after the forward canards and the chine, may be low-RCS caret air intakes with DSIs – Diverterless Supersonic Inlets – which maintain high-quality airflow to the engines over a wide range of conditions. It is believed that the J-20 may have Russian engines. She is likely to be equipped with an AESA radar.
With this new fighter aircraft, and its brand new aircraft carrier, the PLAAF (People’s Liberation Army Air Force) could be on a par with the lead air forces in the world.
