Allison J33-A-21
The General Electric/Allison J33 is a development of the General Electric J31, enlarged to produce significantly greater thrust, starting at and ending at with an additional low-altitude boost to with water-alcohol injection. Development The J33 was originally developed by General Electric as a follow-on to their work with the designs of Frank Whittle during World War II. Their first engine was known as the General Electric I-A, but after major changes to adapt it to US production and to increase thrust, it started limited production as the I-16 in 1942, the 16 referring to its thrust. Full production started as the J31 when the United States Army Air Forces introduced common naming for all their engine projects. Along with the I-16, GE also started work on an enlarged version, known as the I-40. As the name implied, the engine was designed to provide . Apart from size, the main difference between I-16 and the I-40 was the combustion system: the I-16 had ten reverse-flow c ...

P-59 Airacomet
The Bell P-59 Airacomet was a single-seat, twin jet-engine fighter aircraft that was designed and built by Bell Aircraft during World War II, the first produced in the United States. As the British were further along in jet engine development, they donated an engine for the United States to copy in 1941 that became the basis for the General Electric jet used by the P-59 a year later. Because the plane was underpowered, the United States Army Air Forces (USAAF) was not impressed by its performance and canceled half of the original order for 100 fighters, using the completed aircraft as trainers. The USAAF would instead go on to select the Lockheed P-80 Shooting Star as its first operational jet fighter. Although no P-59s entered combat, the aircraft paved the way for later generations of U.S. turbojet-powered aircraft. Design and development Major General Henry H. "Hap" Arnold became aware of the UK's jet program when he attended a taxiing demonstration of the Gloster E.2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed T2V-1
The Lockheed T2V SeaStar, later called the T-1 SeaStar, is a carrier-capable jet trainer for the United States Navy that entered service in May 1957. Developed from the Lockheed T-33 (itself derived from the Lockheed P-80 Shooting Star), it was powered by one Allison J33 engine. Design and development Starting in 1949, the U.S. Navy used the Lockheed T-33 for land-based jet aircraft training. The T-33 was a derivative of the Lockheed P-80/F-80 fighter and was first named TO-2, then TV-2 in Navy service. However, the TV-2 was not suitable for operation from aircraft carriers. The persisting need for a carrier-compatible trainer led to a further, more advanced design development of the P-80/T-33 family, which came into being with the Lockheed designation L-245 and USN designation T2V. Lockheed's demonstrator L-245 first flew on 16 December 1953 and production deliveries to the US Navy began in 1956. Compared to the T-33/TV-2, the T2V was almost totally re-engineered for car ...

Grumman F9F-7
The Grumman F9F/F-9 Cougar is a carrier-based fighter aircraft for the United States Navy and United States Marine Corps. Based on Grumman's earlier F9F Panther, the Cougar replaced the Panther's straight wing with a more modern swept wing. Thrust was also increased with the installation of a newer, more powerful engine. The Navy considered the Cougar an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6. Design and development Early development Rumors that the Soviet Union had produced a swept-wing fighter had circulated a year before the Mikoyan-Gurevich MiG-15 first appeared at air shows in 1949. Despite the level of activity taking place with swept-wing aircraft, the Navy was not initially focused on the development of such aircraft. This was largely because the Navy's focus at the time was defending the battle group against high speed, high altitude bombers with interceptors, as well as escorting medium-range ...

Chance-Vought Regulus
The SSM-N-8A Regulus or the Regulus I was a United States Navy-developed ship-and-submarine-launched, nuclear-capable turbojet-powered second generation cruise missile, deployed from 1955 to 1964. Its development was an outgrowth of U.S. Navy tests conducted with the German V-1 missile at Naval Air Station Point Mugu in California. Its barrel-shaped fuselage resembled that of numerous fighter aircraft designs of the era, but without a cockpit. Test articles of the Regulus were equipped with landing gear and could take off and land like an airplane.''Regulus: The First Nuclear Missile Submarines'' documentary, Spark, 2002 When the missiles were deployed they were launched from a rail launcher, and equipped with a pair of Aerojet JATO bottles on the aft end of the fuselage. History Design and development In October 1943, Chance Vought Aircraft Company signed a study contract for a range missile to carry a warhead. The project stalled for four years, however, until May 1947, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin P4M Mercator
The Martin P4M Mercator was a maritime reconnaissance aircraft built by the Glenn L. Martin Company. The Mercator was an unsuccessful contender for a United States Navy requirement for a long-range maritime patrol bomber, with the Lockheed P2V Neptune chosen instead. It saw a limited life as a long-range electronic reconnaissance aircraft. Its most unusual feature was that it was powered by a combination of piston engines and turbojets, the latter being in the rear of the engine nacelles. Design and development Work began on the Model 219 in 1944, as a replacement for the PB4Y Privateer long-range patrol bomber, optimised for long range minelaying missions, with the first flight being on 20 October 1946.Lake and Dorr 2000, p.139. A large and complicated aircraft, it was powered by two Pratt & Whitney R4360 Wasp Major 28-cylinder radial engines. To give a boost during takeoff and combat, two Allison J33 turbojets were fitted in the rear of the two enlarged engine nacelles, the i ...

Pratt & Whitney R-4360 Wasp Major
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II. First run in 1944, at , it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at the most powerful. It was the last of the Pratt & Whitney Wasp family, and the culmination of its maker's piston engine technology. The war was over before it could power airplanes into combat. It powered many of the last generation of large piston-engined aircraft before turbojets, but was supplanted by equivalent (and superior) powered turboprops (such as the Allison T56). Its main rival was the twin-row, 18-cylinder, nearly displacement, up to Wright R-3350 Duplex-Cyclone, first run some seven years earlier (May 1937). Design and development The R-4360 was a 28-cylinder four-row air-cooled radial engine. Each row of seven air-cooled cylinders possessed a slight angular offset from the previous, forming ...

The hyphen-minus is the most commonly used type of hyphen, widely used in digital documents. It is the only character that looks like a minus sign or a dash in many character sets such as ASCII or on most keyboards, so it is also used as such. The name "hyphen-minus" derives from the original ASCII standard, where it was called "hyphen(minus)". The character is referred to as a "hyphen", a "minus sign", or a "dash" according to the context where it is being used. Description In early monospaced font typewriters and character encodings, a single key/code was almost always used for hyphen, minus, various dashes, and strikethrough, since they all have a roughly similar appearance. The current Unicode Standard specifies distinct characters for a number of different dashes, an unambiguous minus sign ("Unicode minus") at code point U+2212, and various types of hyphen including the unambiguous "Unicode hyphen" at U+2010 and the hyphen-minus at U+002D. When a hyphen is called for, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Air Engineering Station Lakehurst
Lakehurst Maxfield Field, formerly known as Naval Air Engineering Station Lakehurst (NAES Lakehurst), is the naval component of Joint Base McGuire–Dix–Lakehurst (JB MDL), a United States Air Force-managed joint base headquartered approximately east-southeast of Trenton in Manchester Township and Jackson Township in Ocean County, New Jersey, United States. It is primarily the home to Naval Air Warfare Center Aircraft Division Lakehurst, although the airfield supports several other flying and non-flying units as well. Its name is an amalgamation of its location and the last name of Commander Louis H. Maxfield, who lost his life when the R-38/USN ZR-2 airship crashed during flight on 24 August 1921 near Hull, England. When it was consolidated with McGuire Air Force Base and Fort Dix in October 2009, it became the naval component of JB MDL – a United States Air Force– controlled installation – and was placed under the 87th Air Base Wing.
