[2] The aircraft was officially unveiled at the 2013 Army Aviation Association of America's (AAAA) Annual Professional Forum and Exposition in Fort Worth, Texas. The V-280 made its first flight on 18 ...
CFM, which this month celebrates its 50th anniversary, is testing a collection of technologies that could result in an open rotor engine whose main fan would be larger and more visible in order to ...
Under development. The Leonardo Next-Generation Civil Tiltrotor (NextGenCTR or NGCTR) is a tiltrotor aircraft demonstrator designed and developed by the Italian aerospace company Leonardo S.p.A. Studies for a two times larger tiltrotor than the AgustaWestland AW609 started in 2000. Since 2014, its development is sponsored by the European Union ...
Flettner rotor. A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow. [1] The rotor sail is named after the German ...
The Sikorsky–Boeing SB-1 Defiant (stylized as " SB>1 "; company designation S-100) was the Sikorsky Aircraft and Boeing entry for the United States Army 's Future Long-Range Assault Aircraft program to replace the Sikorsky UH-60 Black Hawk. It is a compound helicopter with rigid coaxial rotors, powered by two Honeywell T55 turboshaft engines ...
The Bell Boeing V-22 Osprey. A tiltrotor is an aircraft that generates lift and propulsion by way of one or more powered rotors (sometimes called proprotors) mounted on rotating shafts or nacelles usually at the ends of a fixed wing. Almost all tiltrotors use a transverse rotor design, with a few exceptions that use other multirotor layouts.
Rotorcraft. A rotorcraft or rotary-wing aircraft is a heavier-than-air aircraft with rotary wings or rotor blades, which generate lift by rotating around a vertical mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by ...
The VoloCity, Volocopter is the fourth generation and first series model of its flying machine after the Volocopter VC200 / 2X. It is equipped with two vertical stabilisers to keep the flight direction more stable. [3][4] The device is aligned with the SC-VTOL regulations published by EASA in July 2019. In June 2021, the model 2X performed a ...
