De Havilland Gyron
The de Havilland PS.23 or PS.52 Gyron, originally the Halford H-4, was Frank Halford's last turbojet design while working for de Havilland. Intended to outpower any design then under construction, the Gyron was the most powerful engine of its era, producing "dry", and with afterburner, reheat. The design proved too powerful for contemporary aircraft designs and saw no production use. It was later scaled down to 45% of its original size to produce the de Havilland Gyron Junior, which was more successful. Design and development The Gyron was Halford's first axial-flow design, a complete departure from his earlier centrifugal-flow engines based on Frank Whittle, Whittle-like designs, the de Havilland Goblin, Goblin (H-1) and de Havilland Ghost, Ghost (H-2). The Gyron was also one of the first engines designed specifically for supersonic flight. The Gyron first ran in 1953. Flight testing started in 1955 on a modified Short Sperrin, a bomber prototype designed as a fallback i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Aircraft Museum
The de Havilland Aircraft Museum, formerly the de Havilland Aircraft Heritage Centre, is a volunteer-run aviation museum in London Colney, Hertfordshire, UK. The Museum's mission is to preserve and communicate the de Havilland Heritage to ensure that current and future generations of all ages will understand de Havilland’s contribution to innovative British Aviation technology. The collection was originally built around the definitive prototype and restoration shops for the de Havilland Mosquito and now also includes several examples of the de Havilland Vampire – the third operational jet aircraft in the world. The museum is the largest such museum devoted to one manufacturer in the country. History Salisbury Hall The site has been occupied by a number of large manor houses since the 9th century. The present house was built around 1668 by the London banker James Hoare, bringing with it associations with Charles II and Nell Gwynne, who lived in a cottage by the br ...

V Bomber
The "V bombers" were the Royal Air Force (RAF) aircraft during the 1950s and 1960s that comprised the Nuclear weapons and the United Kingdom, United Kingdom's strategic nuclear strike force known officially as the V force or Bomber Command Main Force. The three models of strategic bomber, known collectively as the ''V class'', were the Vickers Valiant, which first flew in 1951 and entered service in 1955; the Avro Vulcan, which first flew in 1952 and entered service in 1956; and the Handley Page Victor, which first flew in 1952 and entered service in 1957. The V Bomber force reached its peak in June 1964 with 50 Valiants, 70 Vulcans and 39 Victors in service. When it became clear that the Soviet Union's surface-to-air missiles like the S-75 Dvina could bring down high-flying aircraft, the V bomber force changed to low-level attack methods. Additionally the Blue Steel (missile), Blue Steel missile profile was changed to one of low level penetration and release. This reduced its ...

Orenda Iroquois
The Orenda PS.13 Iroquois was an advanced turbojet engine designed for military use. It was developed by the Canadian aircraft engine manufacturer Orenda Engines, a part of the Avro Canada group. Intended for the CF-105 Arrow interceptor, development was cancelled, along with the Arrow, in 1959. Design history For the CF-105 Arrow project, Avro Canada had originally intended to use one of three different engines, all UK designs: Rolls-Royce RB.106, the Bristol B.0L.4 ''Olympus'', or a license-built version of the Olympus, the Curtiss-Wright J67. The RB.106 and J67 were selected as the primary and backup engines for the new design. However, both the RB.106 and J67 were cancelled during the Arrow's design phase, too far into the program to select the Olympus. Orenda Engines quickly responded with the PS.13 Iroquois design. In overall design terms, the PS.13 was similar to the RB.106, using a "two-spool" layout with low-pressure and high-pressure sections of the compresso ...

JP-4
JP-4, or JP4 (for "Jet Propellant") was a jet fuel, specified in 1951 by the United States Department of Defense (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 ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

1957 Defence White Paper
The 1957 White Paper on Defence (Cmnd. 124) was a British white paper issued in March 1957 setting forth the perceived future of the British military. It had profound effects on all aspects of the defence industry but probably the most affected was the British aircraft industry. Duncan Sandys, the recently appointed Minister of Defence, produced the paper. The decisions were influenced by two major factors: the finances of the country and the coming of the missile age. In the past, combat in the air would have been between aircraft, with high flying bombers carrying nuclear weapons and fast interceptor fighter aircraft trying to stop them. Now the ballistic missile could deliver these weapons with no possible defensive response. In this new environment, the interceptors and surface-to-air missiles (SAMs), along with their associated radar networks, seemed superfluous. Likewise, it appeared new manned aircraft of any sort would have little utility in airspace dominated by SAMs. Num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
