Piasecki VZ-8 Airgeep
The Piasecki VZ-8 Airgeep (company designation PA-59) was a prototype vertical takeoff and landing (VTOL) aircraft developed by Piasecki Aircraft. The Airgeep was developed to fulfill a U.S. Army Transportation Research Command contract for a flying jeep in 1957. The flying jeep was envisioned to be smaller and easier to fly than a helicopter. Design and development To meet the US Army's requirement, Piasecki's design featured two tandem, three-blade ducted rotors, with the crew of two seated between the two rotors. Power was by two Lycoming O-360-A2A piston engines, driving the rotors by a central gearbox. The first of two aircraft ordered by the Army, initially designated the Model 59K Skycar (and later renamed Airgeep) by Piasecki and designated VZ-8P by the Army, flew on 22 September 1958.Harding 1998, p.11.PA-59K: ''Histor ...

Piasecki Aircraft
The Piasecki Aircraft Corporation (PiAC) is a manufacturer of aircraft, principally advanced rotorcraft. It was founded by American vertical flight pioneer Frank Piasecki to develop compound helicopters and other advanced rotorcraft after he was ousted from the leadership of his first company, Piasecki Helicopter.Trimble 1982, pp. 257–258. History The company's origins dated back to 1936 with the formation of the P-V Engineering Forum in 1940 and it was renamed the Piasecki Helicopter Corporation in 1946. After a falling out with other owners, Frank Piasecki and some of his design team left to form Piasecki Aircraft Corporation in 1955. The Piasecki Aircraft Corporation is based in Essington, Pennsylvania and is run by Frank Piasecki's sons; Frederick Weyerhaeuser Piasecki is chairman and John Weyerhaeuser Piasecki is president and CEO. In 2005, the company was selected by the United States Army as the prime contractor for two Future Combat Systems (FCS) unmanned aerial vehic ...

Lycoming O-360-A2A
The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW), with the basic O-360 producing 180 horsepower. The engine family has been installed in thousands of aircraft, including the Cessna 172, Piper Cherokee/Archer, Grumman Tiger, and many home-built types. It has a factory rated time between overhaul (TBO) of 2000 hours or twelve years. O-360 family engines are also widely used in airboats, most notably in the Hurricane Aircats used by the US Army during the Vietnam War. The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2. The Lycoming IO-390 is an O-360 which has had its cylinder bore increased by , developing . Series The O-360 family of engines comprises 167 different models with 12 different prefixes. All have a displ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lift Fan
Lift fan is an aircraft configuration in which lifting fans are located in large holes in an otherwise conventional fixed wing or fuselage. It is used for V/STOL operation. The aircraft takes off using the fans to provide lift, then transitions to fixed-wing lift in forward flight. Several experimental craft have been flown, but only the F-35 Lightning II entered into production. History A number of experimental aircraft were evaluated in the USA during the late 1950s and throughout much of the 1960s. The Republic Aviation Republic AP-100, AP-100 was a prototype VTOL 6x General Electric J85 Turbojet engined nuclear capable strike fighter concept designed by Alexander Kartveli that had 3x ducted fans in the centre of its fuselage and tail as a possible contender for the TFX Program. The Avro Canada Avrocar, commissioned by the USA, was intended to be a technology demonstrator for a supersonic VTOL aircraft. It featured a single central fan in a circular flying wing, with engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1950s United States Military Utility Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Air Enthusiast
''Air Enthusiast'' was a British, bi-monthly, aviation magazine, published by the Key Publishing group. Initially begun in 1974 as ''Air Enthusiast Quarterly'', the magazine was conceived as a historical adjunct to '' Air International'' magazine. ''Air International'' was (and still is) involved with current aviation topics and the ''Quarterly'' concerned itself with historical matters. Each issue contained 80 pages; as a result certain articles were divided and each part appeared over a number of issues. ''Air Enthusiast'' was illustrated with colour and black-and-white photos, diagrams, profiles and three-view drawings. Earlier issues featured cutaway drawings, but these were dropped. The articles provided detail for varieties of aircraft An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from ...

Avro Canada VZ-9 Avrocar
The Avro Canada VZ-9 Avrocar was a VTOL aircraft developed by Avro Canada as part of a secret U.S. military project carried out in the early years of the Cold War. The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single "turborotor" blowing exhaust out of the rim of the disk-shaped aircraft. In the air, it would have resembled a flying saucer. Originally designed as a fighter aircraft, fighter-like aircraft capable of very high speeds and altitudes, the project was repeatedly scaled back over time and the U.S. Air Force eventually abandoned it. Development was then taken up by the U.S. Army for a tactical combat aircraft requirement, a sort of high-performance helicopter.Milberry 1979, p. 137. In flight testing, the Avrocar proved to have unresolved thrust and stability problems that limited it to a degraded, low-performance flight envelope; subsequently, the project was cancelled in September 1961. Through the history of the program, the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbomeca Artouste IIC
The Turbomeca Artouste is an early French turboshaft engine, first run in 1947. Originally conceived as an auxiliary power unit (APU), it was soon adapted to aircraft propulsion, and found a niche as a powerplant for turboshaft-driven helicopters in the 1950s. Artoustes were licence-built by Bristol Siddeley (formerly Blackburn) in the UK, Hindustan Aeronautics Limited in India, and developed by Continental CAE in the US as the Continental T51. Two major versions of the Artouste were produced. The Artouste II family, mainly used in the Aérospatiale Alouette II helicopter, had a one-stage centrifugal compressor and a two-stage turbine, with gearbox-limited power of .
