Vertical Takeoff And Landing
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes. Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off & landing), STOL (short take-off & landing), or STOVL (short take-off & vertical landing). Others, such as some helicopters, can only operate as VTOL, due to the aircraft lacking landing gear that can handle taxiing. VTOL is a subset of V/STOL (vertical or short take-off & landing). Some lighter-than-air aircraft also qualify as VTOL aircraft, as they can hover, takeoff and land with vertical approach/departure profiles. Electric vertical takeoff and landing aircraft, or eVTOLs, are being developed along with more autonomous flight control tech ...

Takeoff And Landing
Aircraft have different ways to take off and land. Conventional airplanes accelerate along the ground until reaching a speed that is sufficient for the airplane to takeoff and climb at a safe speed. Some airplanes can take off at low speed, this being a short takeoff. Some aircraft such as helicopters and Harrier jump jets can take off and land vertically. Rockets also usually take off vertically, but some designs can land horizontally. Horizontal takeoff and landing Aircraft Conventional takeoff and landing (CTOL) =Takeoff= Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground ( taxiing) to flying in the air, usually starting on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier), no runway is needed. Takeoff is the opposite of landing. =Landing= Landing is the last part of a flight, where a flying aircraft or spacecraft (or animals) returns to the g ...

EVTOL
An electric vertical take-off and landing (eVTOL) aircraft is a variety of VTOL (vertical take-off and landing) aircraft that uses electric power to hover, takeoff and landing, take off, and land vertically. This technology came about owing to major advances in electric propulsion (Electric motor, motors, Electric battery, batteries, fuel cells, Electronic speed control, electronic controllers) and the emerging need for new aerial vehicles for Advanced Air Mobility and Urban Air Mobility that can enable greener and quieter flights. Electric and hybrid propulsion systems (EHPS) have also the potential of lowering the operating costs of aircraft. Original eVTOL aircraft designs are being developed by original equipment manufacturers (OEMs) that include legacy manufacturers such as Airbus, Boeing, Embraer, Honda, Hyundai Motor Company, Hyundai, and Toyota, as well as several start-up companies including Archer Aviation, EHang, Joby Aviation, Overair, and Volocopter.

Convair XFY-1 Pogo 2
Convair, previously Consolidated Vultee Aircraft Corporation, was an American aircraft-manufacturing company that later expanded into rockets and spacecraft. The company was formed in 1943 by the merger of Consolidated Aircraft and Vultee Aircraft. In 1953, it was purchased by General Dynamics, and operated as their Convair Division for most of its corporate history. Convair is best known for its military aircraft; it produced aircraft such as the Convair B-36 Peacemaker and Convair B-58 Hustler strategic bombers, and the Convair F-102 Delta Dagger and Convair F-106 Delta Dart interceptors. It also manufactured the first Atlas rockets, including the rockets that were used for the crewed orbital flights of Project Mercury. The company's subsequent Atlas-Centaur design continued this success and derivatives of the design remain in use as of 2025. The company also entered the jet airliner business with its Convair 880 and Convair 990 designs. These were smaller tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focke-Achgelis Fa 269
The Focke-Achgelis Fa 269 was a tiltrotor VTOL aircraft project designed by Henrich Focke. Development Conceived as a single-seat fighter, the Fa 269 project resulted from a design study order issued by the Reich Air Ministry to Focke-Achgelis in 1941. The order called for a local defence fighter which would combine the VTOL capabilities of a helicopter with the speed and economy of a conventional fixed-wing aircraft. A large amount of wind tunnel testing was undertaken, along with work on gearboxes, drives and power-pivoting mechanisms, and a full-scale mock-up of the aircraft was built to demonstrate the VTOL concept, but much of this was destroyed by Allied bombing raids and all work was shelved in 1944, when Focke-Achgelis estimated that there was little likelihood of a practical prototype being available before 1947. Design A mid-wing monoplane, the Fa 269 was to have been powered by a single BMW 801 air-cooled radial engine The radial engine is a reciprocating engine, ...

Heinrich Focke
Henrich Focke (8 October 1890 – 25 February 1979) was a German aviation pioneer from Bremen and also a co-founder of the Focke-Wulf company. He is best known as the inventor of the Fw 61, the first successful, practical, and fully controllable helicopter, first flown in 1936. He has been called "father of the helicopter". Biography Early life Henrich Focke was born in Bremen on 8 October 1890, Focke studied at Leibniz University Hannover, where he became friends with Georg Wulf in 1911. In 1914, he and Wulf both reported for military service and Focke was deferred due to heart problems, but was eventually drafted into an infantry regiment. After serving on the Eastern front, he was transferred to the Imperial German Army Air Service. Focke graduated in 1920 as Dipl-Ing with distinction. His first job was with the Francke Company of Bremen as a designer of water-gas systems. Focke-Wulf and Focke-Achgelis In 1923, with Wulf and Dr. Werner Naumann, Focke co-founded ...

In 1884 he immigrated to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Berliner
Henry Adler Berliner (December 13, 1895 – May 1, 1970) was a United States aircraft and helicopter pioneer. Sixth son of inventor Emile Berliner, he was born in Washington, D.C. He studied mechanical engineering at Cornell University for two years before attending Massachusetts Institute of Technology. After a short time as aerial photographer with the Army Air Service, in 1919 Henry moved back to Washington to help his father with the helicopter research that had been underway for many years (since 1903 New International Encyclopedia). Using a Le Rhône engine of 80 hp mounted on a test stand, Henry was able to hover and move forward, but only with assistants holding on to stabilize the contraption. In 1922, he bought a surplus Nieuport 23 fighter's fuselage, added a Bentley 220 hp engine on the front, and connected it by geared shafts to two horizontal rotors mounted on a truss extending sideways from the fuselage. A third horizontal rotor at the rear provided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harrier Jump Jet
The Harrier, informally referred to as the Harrier jump jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). Named after the bird of prey, it was originally developed by British manufacturer Hawker Siddeley in the 1960s. The Harrier emerged as the only truly successful V/STOL design of the many attempted during that era. It was conceived to operate from improvised bases, such as car parks or forest clearings, without requiring large and vulnerable air bases. Later, the design was adapted for use from aircraft carriers. There are two generations and four main variants of the Harrier family, developed by both UK and US manufacturers: * Hawker Siddeley Harrier (first generation) ** British Aerospace Sea Harrier * McDonnell Douglas AV-8B Harrier II (second generation) ** British Aerospace Harrier II The Hawker Siddeley Harrier is the first generation-version and is also known as the AV-8A or AV-8C Harrier; i ...
