Northrop T-38 Talon
The Northrop T-38 Talon is a two-seat, twinjet supersonic jet trainer. It was the world's first, and the most produced, supersonic trainer. The T-38 remains in service in several air forces. The United States Air Force (USAF) operates the most T-38s. In addition to training USAF pilots, the T-38 is used by NASA. The U.S. Naval Test Pilot School in Patuxent River, Maryland, is the principal US Navy operator (other T-38s were previously used as USN for dissimilar air combat training until replaced by the similar Northrop F-5 Tiger II). Pilots of other NATO nations fly the T-38 in joint training programs with USAF pilots. , the T-38 has been in service for over 60 years with its original operator, the United States Air Force. In September 2018, USAF announced the replacement of the Talon by the Boeing-Saab T-7 Red Hawk with phaseout to begin in 2023. Design and development In 1952 Northrop began work on a fighter project, the '' N-102 Fang'', with shoulder-mounted d ...

T-38 Tank
The T-38 amphibious scout tank was a Soviet amphibious light tank that saw service in World War II. Developed as a modernized version of the earlier T-37A light tank, the T-38 proved to be only a moderate improvement over its predecessor, and was eventually replaced in 1940 by the T-40. History Early trials of the T-37A revealed many deficiencies in its design, including limited range, sub-par buoyancy, and an unreliable transmission and running gear that could cause its tracks to fall off while on the move.Baryatinskiy, p. 15-19 Development of an improved version of the tank that would fix these flaws was begun in late 1934 at Factory No. 37 in Moscow, under the direction of Chief Designer N. Astrov and Chief Engineer N. Kozyrev.Zaloga, p. 77-79 The redesign proved to be so extensive that the project was given the independent designation T-38, and a prototype was completed by June 1935. The T-38 retained many design features of the T-37A, including its repurposed GAZ-AA en ...

Allison T38
The Allison T38 (company Model 501) was an early turboprop engine developed by Allison Engine Company during the late 1940s. The T38 became the basis for the very successful family of Allison T56 turboprop engine. Design and development Developed as a stand-alone single section of the T40 (Model 500) twin engine to aid in development of the T40, the T38 started life with a 19-stage axial compressor, eight can type combustion chambers, a 4-stage turbine driving the compressor and the extension shaft to the reduction gearbox. Initially rated at the T38 first ran in 1947 and flew in the nose of a Boeing B-17 Flying Fortress test-bed on 19 April 1949, rated at . Problems with gearbox vibration and combustion were dealt with during the test program and were mirrored by problems in the Allison T40 programme. The engines fitted to the Convair CV-240-21 Turboliner were rated to equivalent. In 1951, the United States Air Force decided that the production version of the Beechcraft XT-3 ...

T38 (classification)
T38 and CP8 are disability sport classification for disability athletics intended for people with cerebral palsy. It includes people who have coordination impairments such as hypertonia, ataxia and athetosis. Runners in this class may appear to have a slight limp when they are running but otherwise have a stride similar to able-bodied runners. Events for this class include 100 meters, 400 meters, 1,500 meters, and the long jump. Sport This classification is for disability athletics. This classification is one of seven classifications for athletes with cerebral palsy. Similar classifications are T32, T33, T34, T35, T36, T37 and T38. The T35 to T38 classes are classes for ambulant sportspeople. The Australian Paralympic Committee defines this classification as being for "Minimal hemiplegia, ataxia, diplegia or athetosis. May have minimal co-ordination problems, good balance. Runs and jumps freely." The International Paralympic Committee defined this classification o ...
