Dassault Balzac V
The Dassault Balzac V was a French vertical takeoff and landing (VTOL) testbed of the early 1960s. It was built by Dassault Aviation from a prototype Dassault Mirage III, Mirage III aircraft to test the configuration for the Dassault Mirage IIIV, Mirage IIIV. The sole example was involved in two major accidents that killed the aircraft's pilot, and was not repaired after the second crash. Design and development Since the Rolls-Royce RB162 lift engines specified for the Mirage IIIV were not expected to be available before 1963, Dassault modified the first Mirage III prototype to serve as an interim VTOL testbed. Eight Rolls-Royce RB108 lift engines were installed, each with an average maximum takeoff thrust of 9.83 kN (2,210 lbf). The Mirage III's Snecma Atar G.2 propulsion engine was replaced with an Afterburner, un-reheated (non-afterburning) Bristol Siddeley Orpheus BOr 3 with a thrust of 21.57 kN (4,850 lbf). The lift engines were grouped in tandem pairs ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolls-Royce RB108-1A
The Rolls-Royce RB.108 was a British jet engine designed in the mid-1950s by Rolls-Royce specifically for use as a VTOL lift engine. It was also used to provide horizontal thrust in the Short SC.1. Design and development The RB.108 was the first direct-lift turbojet produced by Rolls-Royce. It originated from a VTOL concept in which Alan A. Griffith proposed using a small number of specialised lift engines in a VTOL aircraft, separate from the engines which provided forward propulsion. Its power output (thrust) was not high enough for use as a practical engine in a production aircraft and was used only for research into VTOL. It was constructed from conventional materials. (The next lift engine, the RB.162, would have a compressor built mainly from glass-fibre composite and have a higher T/W ratio.) The RB.108 bearings and oil system were designed to operate with an engine attitude envelope which covered engine and aircraft tilting while transitioning between hovering and f ...

1960s French Fighter Aircraft
Year 196 ( CXCVI) was a leap year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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. Events By place Roman Empire * Emperor Septimius Severus attempts to assassinate Clodius Albinus but fails, causing Albinus to retaliate militarily. * Emperor Septimius Severus captures and sacks Byzantium; the city is rebuilt and regains its previous prosperity. * In order to assure the support of the Roman legion in Germany on his march to Rome, Clodius Albinus is declared Augustus by his army while crossing Gaul. * Hadrian's wall in Britain is partially destroyed.

List Of Military Aircraft Of France
France has used many military aircraft both in the French Air and Space Force, and other branches of its armed forces. Multiple aircraft were designed and built in France, but many aircraft from elsewhere, or part of joint ventures have been used as well. Lighter-than-air aircraft such as dirigibles and balloons found use starting in the 19th century used mainly for observation. The advent of World War I saw an explosion in the number France's aircraft, though development slowed after. While having many promising designs in development in the 1930s, government wrangling delayed development enough there was little available at the out break of World War II. The armistice in 1940 marked a low point, with Vichy France being allowed only reduced numbers and development halting. Many French aircraft were captured and used by Nazi Germany and its allies. Some aircraft that did escape served with the Allies or Free French forces, who also used many other types of allied aircraft. The col ...

Yakovlev Yak-141
The Yakovlev Yak-141 (; NATO reporting name "Freestyle"), also known as the Yak-41, is a Soviet supersonic VTOL, vertical takeoff/landing (VTOL) fighter aircraft designed by Yakovlev. Intended as a replacement for the Yak-38, it was designed as a supersonic fleet defence fighter capable of STOVL/VTOL operating from Soviet carriers. Four prototypes were built before the project's cancellation. Design and development Known internally as "Product 48", the Yak-41 was intended to replace the Yak-38 in service with the Soviet Navy. It went through significant design evolution. Configurations studied by Yakovlev included a twin-engine configuration, which was rejected due to asymmetric thrust issues in the event of an engine failure during landing, and a single-engined configuration, with lift jets to allow for vertical takeoff and landing, was selected. The engines were controlled digitally; manuverability during the hover was provided by reaction control jets, using excess airflow f ...

Yakovlev Yak-38
The Yakovlev Yak-38 (; NATO reporting name: "Forger") was Soviet Naval Aviation's only operational VTOL strike fighter aircraft in addition to being its first operational carrier-based fixed-wing aircraft. It was developed specifically for, and served almost exclusively on, the s (heavy aircraft cruiser, aviation cruiser in Russian classification). Design and development Designed by the Yakovlev, A.S. Yakovlev Design Bureau, the first drawings showed a supersonic aircraft strongly resembling the Hawker P.1154 in study in the United Kingdom, but with two R27-300 engines. Supersonic performance would have implied many difficulties of development, and it was decided to initially develop a relatively simple aircraft limited to Mach Number, Mach 0.95. Although the Yak-38 and Yak-38M were developed from the land-based Yakovlev Yak-36, the aircraft had almost nothing in common. The prototype VM-01 was finished on 14 April 1970. Though outwardly similar to the British Hawker Siddel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockwell XFV-12
The Rockwell XFV-12 was a prototype supersonic United States Navy fighter which was built in 1977. The XFV-12 design attempted to combine the Mach 2 speed and AIM-7 Sparrow armament of the McDonnell Douglas F-4 Phantom II in a VTOL (vertical takeoff and landing) fighter for the small Sea Control Ship which was under study at the time. On paper, it looked superior to the subsonic Hawker Siddeley Harrier attack fighter. However, it was unable to demonstrate an untethered vertical takeoff and its inability to meet performance requirements resulted in the program's termination. Design and development In 1972, the Navy issued a request for proposals for a next generation supersonic V/STOL fighter/attack aircraft. Rockwell's design with the XFV-12 won against Convair's proposal with the Convair Model 200. The XFV-12A, despite its concept being considered risky compared to that of the Harrier, was selected for development. To reduce costs, the nose from the Douglas A-4 Skyhawk ...
