Lycoming T53-L-13
The Lycoming T53, (company designation LTC-1) is a turboshaft engine used on helicopters and (as a turboprop) fixed-wing aircraft since the 1950s. It was designed at the Lycoming Turbine Engine Division in Stratford, Connecticut, by a team headed by Anselm Franz, who was the chief designer of the Junkers Jumo 004 during World War II. A much larger engine, similar in overall design, became the Lycoming T55 produced by Honeywell Aerospace. The T53 model is produced by Ozark Aeroworks LLC.

Anselm Franz
Anselm Franz (January 20, 1900—November 18, 1994) was a pioneering Austrian jet engine engineer known for the development of the Jumo 004, the world's first mass-produced turbojet engine by Nazi Germany during World War II, and his work on turboshaft designs in the U.S. after the war as part of Operation Paperclip, including the T53, the T55, the AGT-1500, and the PLF1A-2, the world's first high-bypass turbofan engine. Early life Born in Schladming, Austria, in 1900, Franz studied mechanical engineering at the Graz University of Technology and earned a doctoral degree from the University of Berlin. Franz worked as a design engineer at a company in Berlin, where he developed hydraulic torque converters. In 1933 Franz joined the Sturmabteilung. Junkers Aircraft In 1936, he joined Junkers, and during much of the 1930s he was in charge of supercharger and turbocharger development. Meanwhile Hans von Ohain's first engines were being run at Heinkel, although there was little officia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doak VZ-4
The Doak VZ-4 (or Doak Model 16) was an American prototype Vertical Takeoff and Landing (VTOL) aircraft built in the 1950s for service in the United States Army. Only a single prototype was built, and the U.S. Army withdrew it from active trials in 1963. Development Edmund R. Doak, Jr., a self-taught engineer and vice president of Douglas Aircraft Company, founded Doak Aircraft Company in Torrance, California, in 1940. The company grew to 4,000 employees during World War II, with subcontracts from every major American aircraft manufacturer. These included molded plywood fuselages for trainers such as the AT-6 and Vultee BT-13, and doors, hatches and gun turrets for a multitude of aircraft. Doak proposed a VTOL aircraft to the U.S. Armys Army Transportation and Research and Engineering Command at Fort Eustis in Newport News, Virginia, in 1950. He touted the aircraft as able to take off and land in a small area, hover and loiter over a target area, and fly backwards like a h ...

Boeing Vertol VZ-2
The Vertol VZ-2 (or Model 76) was a research aircraft built in the United States in 1957 to investigate the tiltwing approach to vertical take-off and landing. Design and development The aircraft had a fuselage of tubular framework (originally uncovered) and accommodation for its pilot in a helicopter-like bubble canopy. The T-tail incorporated small ducted fans to act as thrusters for greater control at low speeds. Ground tests began in April 1957 and on 13 August, the VZ-2 took off for the first time in hover mode only. On 23 July 1958, the aircraft made its first full transition from vertical flight to horizontal flight. By the time the test program ended in 1965, the VZ-2 had made some 450 flights, including 34 full transitions. The aircraft has been preserved by the National Air and Space Museum in storage at the Paul E. Garber Preservation, Restoration, and Storage Facility.

Bell XV-15
The Bell XV-15 is an American tiltrotor VTOL aircraft. It was the second successful experimental tiltrotor aircraft and the first to demonstrate the concept's high speed performance relative to conventional helicopters. Development Early VTOL rotor aircraft The idea of building VTOL aircraft using helicopter-like rotors at the wingtips originated in the 1930s. The first design resembling modern tiltrotors was patented by George Lehberger in May 1930, but he did not develop the concept further. In World War II, a German prototype called the Focke-Achgelis Fa 269 was developed starting in 1942, but it never flew. Two prototypes that made it to flight were the one-seat Transcendental Model 1-G and two-seat Transcendental Model 2, both powered by single reciprocating engines. Development started on the Model 1-G in 1947, and it flew in 1954. The Model 1-G flew until a crash in Chesapeake Bay on 20 July 1955, destroying the prototype aircraft but not seriously injuring the pilot. Th ...

Bell UH-1 Iroquois
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing 700 shp (520 kW), by 1966, the Lycoming T53-L-13, ...

Bell AH-1 Cobra
The Bell AH-1 Cobra is a single-engined attack helicopter developed and manufactured by the American rotorcraft manufacturer Bell Helicopter. A member of the prolific Huey family, the AH-1 is also referred to as the HueyCobra or Snake. The AH-1 was rapidly developed as an interim gunship in response to the United States Army's needs in the Vietnam War. It used the same engine, transmission and rotor system of the Bell UH-1 Iroquois, which had already proven itself to be a capable platform during the conflict, but paired it with a redesigned narrow fuselage among other features. The original AH-1, being a dedicated attack helicopter, came equipped with stub wings for various weapons, a chin-mounted gun turret, and an armored tandem cockpit, from which its was operated by a pilot and gunner. Its design was shaped to fulfil a need for a dedicated armed escort for transport helicopter, giving the latter greater survivability in contested environments. On 7 September 1965, the ...

Bell 204/205
The Bell 204 and 205 are the civilian versions of the UH-1 Iroquois single-engine military helicopter of the Huey family of helicopters. They are type-certificated in the transport category and are used in a wide variety of applications, including crop dusting, cargo lifting and aerial firefighting. Development Bell designed its ''Model 204'' in response to a 1955 United States Army requirement for a utility helicopter. The 204 was a giant step forward in helicopter design, being one of the first to be powered by a turboshaft. The turboshaft engine radically improved the practicality of the helicopter due to its light weight and high power-to-weight ratio, lower fuel consumption, and lower maintenance and operating costs. The use of a turboshaft in the 204 allowed it to carry a useful payload over respectable ranges and at reasonable speeds, which resulted in the 204 and subsequent 205 becoming the most successful western helicopter series in terms of numbers built.Frawley, ...

Canadair CL-84 Dynavert
The Canadair CL-84 "Dynavert", designated by the Canadian Forces as the CX-131, was a V/STOL turbine tiltwing monoplane designed and manufactured by Canadair between 1964 and 1972. Only four of these experimental aircraft were built with three entering flight testing. Two of the CL-84s crashed due to mechanical failures, with no fatalities occurring in either of the accidents. Despite the CL-84 being successful in the experimental and operational trials carried out between 1972 and 1974, none of the prospective customers placed any orders for the type. Development Between 1957 and 1963, Canadair carried out research in VTOL (vertical takeoff and landing) technology with the assistance of the National Research Board (NRB) and the Defense Research Board (DRB) of Canada. The studies pointed the way to a unique tilt-wing design. The wing and the powerplants of the aircraft could be tilted hydro-mechanically (recirculating ball actuator) so that the wing incidence changed through 10 ...
