Bristol 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] |

Avro Lancaster
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive-bombing attacks. Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one of the versions, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic bom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IAR-99
The IAR 99 Șoim (''Hawk'') is an advanced trainer and light attack aircraft capable of performing close air support and reconnaissance missions. The IAR 99 replaced the Aero L-29 Delfin and Aero L-39 Albatros as the jet trainer of the Romanian Air Force. The aircraft is of semi-monocoque design, with tapered wings and a swept-back tail unit. A large blade-type antenna installed beneath the nose on the port side of the fuselage gives the IAR 99 trainer a distinctive appearance. Development The design of the aircraft started in 1975 and this would be the first jet trainer fully designed and built in Romania. In 1979 funding was approved for building the first trainer by I.Av. Craiova where the IAR 93 attack aircraft was currently built. The prototype (S-001) flew on 21 December 1985 with Lt. Col. Vagner Ștefănel at the controls.''Air International'' September 1990, pp. 129–133. S-002 served for static (ground) testing, S-003 being the second flying prototype (later re-seria ...

Soko J-22 Orao
The Soko J-22 Orao ( sr-cyr, text=Oрао, translation=eagle) is a Yugoslav twin-engined, subsonic ground-attack and aerial reconnaissance aircraft. It was developed and built in collaboration by SOKO in Yugoslavia and by Avioane Craiova in neighbouring Romania, being known in the latter as the IAR-93 Vultur. The Orao was designed as either a single-seat main attack version or as a combat-capable twin-seat version, the latter being principally intended for advanced flight- and weapons-training duties. It was developed as a joint Yugoslav-Romanian project, known as YuRom, during the 1970s. Early ambitions to produce a supersonic fighter were scuppered by Britain's unwillingness to permit the desired engine to be license-produced in Eastern Europe. Further difficulties in fitting an afterburner to the older Rolls-Royce Viper also hindered development and the performance of early-build aircraft. First flying during November 1974, the resulting aircraft would equip the air forc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Handley Page HP 115
The Handley Page HP.115 was a experimental delta wing aircraft designed and produced by the United Kingdom, British aircraft manufacturer Handley Page. It was built to test the low-speed handling characteristics to be expected from the slender delta configuration anticipated for a future supersonic airliner. The HP.115 was designed during the 1950s as a part of the wider supersonic aircraft research programme that was sponsored by the Ministry of Supply. At the time, both the delta wing and supersonic flight were both relatively recent innovations. By 1956, the Supersonic Transport Committee had been deemed necessary to build a demonstrator to prove that the slender delta wing design was not only suitable for high speed flight but would also be reasonably functional at lower speeds as well. Initially, work centred around an unpowered glider (aircraft), glider, but it was determined that a self-powered aircraft would be more economic. Accordingly, Handley Page was selected to pr ...
