Teledyne CAE T72
The Continental CAE T51 was a small turboshaft engine produced by Continental Aviation and Engineering (CAE) under license from Turbomeca. A development of the Artouste, it was followed by three additional turboshaft engines, the T72, the T65, and the T67. However, none of these engines, including the T51, entered full production. CAE abandoned turboshaft development in 1967 after the XT67 lost to the Pratt & Whitney Canada PT6T (T400) to power the Bell UH-1N Twin Huey.

Turbomeca Artouste II
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 . The Artouste III family, mainly used in Aérospatiale's Alouette III and Lama helicopters, had a two-stage axial-centrifugal compressor and a three-stage turbine, with gearbox-limited power of .

Boeing T50
The Boeing T50 (company designation Model 502) was a small turboshaft engine produced by Boeing. Based on Boeing's earlier Model 500 gas generator, the T50's main application was in the QH-50 DASH helicopter drone of the 1950s.

JP-4
JP-4, or JP4 (for "Jet Propellant") was a jet fuel, specified in 1951 by the U.S. government (MIL-DTL-5624). Its NATO code is F-40. It is also known as avtag. Usage JP-4 was a 50-50 kerosene-gasoline blend. It had a lower flash point than JP-1, but was preferred because of its greater availability. It was the primary U.S. Air Force jet fuel between 1951 and 1995. MC-77 is the Swedish military equivalent of JP-4. Mixture JP-4 was a mixture of aliphatic and aromatic hydrocarbons. It was a flammable transparent liquid with clear or straw color, and a kerosene-like smell. It evaporated easily and floated on water. Although it had a low flash point (), a lit match dropped into JP-4 would not ignite the mixture. JP-4 froze at , and its maximum burning temperature was . JP-4 was a non-conductive liquid, prone to build up static electricity when being moved through pipes and tanks. As it is volatile and has a low flash point, the static discharge could cause a fire.

Aérospatiale Alouette II
The Aérospatiale Alouette II (, "lark"; company designations SE 313 and SA 318) is a French light helicopter originally manufactured by Sud Aviation and later Aérospatiale. It was the first production helicopter powered by a gas turbine engine instead of the heavier conventional piston powerplant. On 12 March 1955, the prototype SE 3130 performed its maiden flight. The Alouette II was a widely used type and popular with operators, with over 1,300 rotorcraft eventually being constructed between 1956 and 1975. The type was predominantly used for military purposes in observation, photography, air-sea rescue, liaison and training, but it has also carried anti-tank missiles and homing torpedoes. As a civilian helicopter, the Alouette II has been used for casualty evacuation (with two external stretcher panniers), crop-spraying and as a flying crane, with a external underslung load. A high-altitude derivative, the SA 315B Lama, was developed and entered operational service in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

O-1 Bird Dog
The Cessna L-19/O-1 Bird Dog is a liaison and observation aircraft. It was the first all-metal fixed-wing aircraft ordered for and by the United States Army following the Army Air Forces' separation from it in 1947. The Bird Dog had a lengthy career in the U.S. military, as well as in other countries. Design and development The U.S. Army was searching for an aircraft that could adjust artillery fire, as well as perform liaison duties, and preferably be constructed of all metal, as the fabric-covered liaison aircraft used during World War II (primarily Stinson and Piper products) had short service lives. After the specification for a two-seat liaison and observation monoplane was issued the Cessna Aircraft Company submitted the Cessna Model 305A, a development of the Cessna 170. The Cessna 305A was a single-engine, lightweight, strut-braced, high-wing monoplane with a tailwheel landing gear. The greatest difference from the Cessna 170 was that the 305A had only two seats, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-59 (New England Air Museum)
The Sikorsky XH-39 (manufacturer designation S-59), developed by Sikorsky Aircraft in 1954, was the U.S. Army's first turbine-powered helicopter. It was fast and innovative, but ultimately rejected by the United States Army in favor of the Bell UH-1 Iroquois. Design and development The four-seat XH-39 was powered by one Continental CAE XT51-T-3 400 shp (298 kW) turboshaft engine, a license-built development of the Turbomeca Artouste. It was developed from a previous Sikorsky model, the H-18 (company model S-52), and had the same layout. It differed in using retractable landing gear, modified tail rotor, and four-blade main rotor. In the end, the U.S. Army selected the Bell XH-40, prototype of the UH-1 Huey. Two YH-18As were modified into XH-39s; one for flight testing and the other for static test. On 26 August 1954, the XH-39 set a world helicopter speed record of 156.005 mph (251 km/h) over a three kilometer closed course at Bradley Field (now Bradley Interna ...

Turbomeca Astazou X
The Turbomeca Astazou is a highly successful series of turboprop and turboshaft engines, first run in 1957. The original version weighed and developed at 40,000 rpm. It was admitted for aviation service on May 29, 1961, after a 150-hour test run. The main developing engineer was G. Sporer. It was named after two summits of the Pyrenees. A simplified version was built by Agusta as the Turbomeca-Agusta TA.230. Design and development The Astazou IIA version was derived from the original Astazou powerplant for use in helicopters. By 1993, 2,200 had been built. As of 2007, it was still in production. However, many aircraft initially equipped with it, especially the heavier ones, have since been upgraded with more powerful engines. The early single-shaft Astazou has a two-stage compressor, with the first stage an axial and the second stage a radial design. It has an annular combustion chamber, after which the combustion gases enter a three-stage axial turbine. Engines have a reduc ...

Light Observation Helicopter
The Light Observation Helicopter (LOH) program was a United States Army program to evaluate, develop and field a light scout helicopter to replace the Army's aging Bell OH-13 Sioux. It gained impetus with the advent of the Vietnam War, and was aided by advances in helicopter technology, specifically the development of the turboshaft engine. History In July 1953, the Office of Lieutenant General John E. Dahlquist, Chief, Army Field Forces (AFF), forwarded desirable military characteristics for a two-place reconnaissance helicopter to Army Headquarters. Nearly a year later, in May 1954, Dahlquist's office once again emphasized the need for replacement aircraft and recommended procurement of troop test quantities of the YH-32. Preliminary evaluation of the YH-32 design revealed that the aircraft was unsuitable for the mission, and the tests were canceled.Weinert 1991, p. 205. In 1955, the Army Field Forces were transformed into the Continental Army Command (CONARC). Dahlquist, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allison Model 250
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
