North American T-2 Buckeye
The North American T-2 Buckeye was the United States Navy's intermediate training aircraft, intended to introduce U.S. Navy and U.S. Marine Corps student naval aviators and student naval flight officers to jets. It entered service in 1959, beginning the replacement process of the Lockheed T2V SeaStar, and was itself replaced by the McDonnell Douglas T-45 Goshawk in 2008. Design and development In 1956, the US Navy issued a requirement for a jet-powered basic trainer to replace its T-28 piston-engined aircraft. (Primary training for the US Navy remained the responsibility of the piston-engined Beechcraft T-34 Mentor while the jet-powered Lockheed T2V SeaStar provided more advanced training). North American Aviation won the US Navy's competition for the new training aircraft in mid-1956 with its NA-241 design.''Air International'' October 1973, pp. 163–164. North American's design, designated the T2J-1 by the US Navy, was a mid-winged monoplane with trainee and instructor sitt ...

Piston-engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...

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 ...

Pratt & Whitney JT12
The Pratt & Whitney JT12, (US military designation J60) is a small turbojet engine. The Pratt & Whitney T73 (Pratt & Whitney JFTD12) is a related turboshaft engine. Design and development The J60 conception and project design began in July 1957 at United Aircraft of Canada (now Pratt & Whitney Canada) in Montreal. The project design details were transferred to the main P&W company in East Hartford and in May 1958, the first prototype, with military designation YJ60-P-1 commenced testing. Flight tests were completed in early 1959; followed by the delivery of the new JT12A-5 engines in July 1959. These were for the two Canadair CL-41 prototype trainers with a rating of 12.9 kN (2,900 lb st). The modified JT12A-3 turbojets with a basic rating of 14.69 kN (3,300 lb st) were tested in the two Lockheed XV-4A Hummingbird VTOL research aircraft. The next version, JT12A-21, had an afterburner which delivered a maximum thrust of 17.91 kN (4,025 lb st). Varian ...

Naval Air Station Meridian
Naval Air Station Meridian or NAS Meridian is a military airport located 11 miles northeast of Meridian, Mississippi in Lauderdale County and Kemper County, and is one of the Navy's two jet strike pilot training facilities. History On July 16, 1957, the first shovel of earth was thrown, marking the beginning of the Naval Auxiliary Air Station (NAAS), which was commissioned July 19, 1961. Captain W.F. Krantz, USN received the golden key to the air station, and senior Mississippi U.S. Senator John C. Stennis was the guest speaker for the ceremony that opened the $60 million base. At that time, the operations area was named McCain Field in honor of the late Admiral John S. McCain, Sr. of Teoc, Mississippi. Training Squadron SEVEN (VT-7) arrived at NAAS Meridian July 12, 1961, then split to form its sister squadron, Training Squadron NINE (VT-9) on December 15. In September 1965, hundreds of planes from Florida bases arrived to escape the wrath of Hurricane Betsy. The Naval Aux ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Westinghouse J34
The Westinghouse J34, company designation Westinghouse 24C, was a turbojet engine developed by Westinghouse Aviation Gas Turbine Division in the late 1940s. Essentially an enlarged version of the earlier Westinghouse J30, the J34 produced 3,000 pounds of thrust, twice as much as the J30. Later models produced as much as 4,900 lb with the addition of an afterburner. It first flew in 1947. The J46 engine was developed as a larger, more powerful version of Westinghouse's J34 engine, about 50% larger. Development Built in an era of rapidly advancing gas turbine engine technology, the J34 was largely obsolete before it saw service, and often served as an interim engine. For instance, the Douglas X-3 Stiletto was equipped with two J34 engines when the intended Westinghouse J46 engine proved to be unsuitable. The Stiletto was developed to investigate the design of an aircraft at sustained supersonic speeds. However, equipped with the J34 instead of its intended engines, it was ser ...
