General Electric J85
The General Electric J85 is a small single-shaft turbojet engine. Military versions produce up to of thrust dry; afterburning variants can reach up to . The engine, depending upon additional equipment and specific model, weighs from . It is one of GE's most successful and longest in service military jet engines, with the civilian versions having logged over 16.5 million hours of operation. The United States Air Force plans to continue using the J85 in aircraft through 2040. Civilian models, known as the CJ610, are similar but supplied without an afterburner and are identical to non-afterburning J85 variants, while the CF700 adds a rear-mounted fan for improved fuel economy. Design and development The J85 was originally designed to power a large decoy missile, the McDonnell ADM-20 Quail. The Quail was designed to be released from a B-52 Stratofortress in-flight and fly for long distances in formation with the launch aircraft, multiplying the number of targets facing the SA-2 su ...

Armstrong Siddeley Viper
The Armstrong Siddeley Viper is a British turbojet engine developed and produced by Armstrong Siddeley and then by its successor companies Bristol Siddeley and Rolls-Royce Limited. It entered service in 1953 and remained in use with the Royal Air Force, powering its Dominie T1 navigation training aircraft until January 2011. Design and development The design originally featured a seven-stage compressor based on their Adder engine — the Viper is in effect a large-scale Adder. Like the similar J85 built in United States, the Viper was originally developed as an expendable engine for production versions of the Jindivik target drone. Like the J85, the limited-life components and total-loss oil systems were replaced with standard systems for use in crewed aircraft. Because it was initially developed as an expendable engine, the Viper was subject to many recurring maintenance issues. This led to the development of the first Power by the Hour program in which operators woul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boom XB-1
The Boom XB-1 "Baby Boom" is a one-third-scale trijet supersonic demonstrator designed by Boom Technology ( dba "Boom Supersonic") as part of development of the Boom Overture supersonic transport airliner. Powered by three General Electric J85s, it is planned to maintain Mach 2.2, with over of range. Taxi tests began in December 2022, with flight tests expected in 2023. Development The design was unveiled in Denver on November 15, 2016, and it was initially intended to make its first subsonic flight in late 2017, powered by three General Electric CJ610 turbojets (a civilian J85), with subsequent supersonic flight testing at Edwards Air Force Base. By April 2017, enough financing was secured to build and fly it. Its preliminary design review was completed by June 2017, with a switch of engine to the military version of the J85 to take advantage of its extra thrust. It was then anticipated that flight tests would start late 2018. In 2017, the composite wing spar was load teste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell X-14
The Bell X-14 (Bell Type 68) is an experimental VTOL aircraft flown in the United States in the 1950s. The main objective of the project was to demonstrate vectored thrust horizontal and vertical takeoff, hover, transition to forward flight, and vertical landing. Design and development Bell constructed the X-14 as an open-cockpit, all-metal (duralumin) monoplane for the USAF. It was powered by two Armstrong Siddeley Viper turbojet engines equipped with thrust deflectors sited at the aircraft's centre of gravity. The engines are fixed in position; transition from vertical to horizontal flight is achieved with a system of movable vanes that control the direction of engine thrust. Top speed was with a service ceiling of . The X-14 was designed using existing parts from two Beechcraft aircraft: wings, ailerons, and landing gear of a Beech Bonanza and the tailcone and empennage of a Beech T-34 Mentor. Operational history The X-14 first flew on 19 February 1957 as a vertical take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Knight SS1 RH
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of n ...

Orenda Engines
Orenda Engines was a Canadian aircraft engine manufacturer and parts supplier. As part of the earlier Avro Canada conglomerate, which became Hawker Siddeley Canada, they produced a number of military jet engines from the 1950s through the 1970s, and were Canada's primary engine supplier and repair company. History Origins The origins of the company stem from World War II. During the war, the National Research Council of Canada ran a small aerodynamics effort similar to NACA in the United States or Royal Aircraft Establishment in the United Kingdom. In 1942 they sent two of their researchers to the UK to take a survey of their efforts and report on what fields of study the Canadians should focus in order to avoid duplication. Over the next year a number of members of the NRC's aerodynamics lab traveled to the UK, and in May 1943 they published their findings in the top secret ''Report on Development of Jet Propulsion in the United Kingdom'', widely known as the Banks Report.

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
