GE T64 turboprop, with the propeller on the left, the gearbox with accessories in the middle, and the gas generator (turbine) on the right. A turboprop is a gas turbine engine that drives an aircraft propeller. [1] A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. [2]
The effort continued with a 5,000 shp (3,700 kW), weighing 1,700 kg (3,700 lb), completed by 1947. Evolution to the TV-12 12,000 shp (8,900 kW) engine required extensive use of new Soviet-developed alloys and was completed in 1951. The NK-12 is the most powerful turboprop engine to enter service, ahead of the Europrop TP400 (in 2005).
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada.Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since.
The General Electric H-Series is a family of turboprop aircraft engines produced by GE BGA Turboprops. The initial H80 is an updated derivative of the Walter M601 , while the H75 and H85 are later derivatives.
One XT57 (PT5), a turboprop development of the J57, was installed in the nose of a JC-124C (BuNo 52-1069), and tested in 1956. [3] [4]Rated at 15,000 shaft horsepower (11,000 kW), the XT57 was the most powerful turboprop engine in existence at the time, [5] and it remains the most powerful turboprop ever built in the United States.

Examples include some aircraft propellers, resulting in the maximum power of a single piston or turboprop engine to drive two propellers in opposite rotation. Contra-rotating propellers are also common in some marine transmission systems, in particular for large speed boats with planing hulls.
Europrop delivered the first TP400 engine for engine testbed flight testing on 19 November 2007. [18] In June 2008, the TP400 had a first ground run on the inboard port wing of the C-130K engine testbed, and integration was completed onto the first A400M production aircraft. [19]
The YT34 engine with three wide-bladed propellers was made for two Navy Lockheed R7V-2 Constellation (C-121s) variants, for testing. Flight tests were on 1 September 1954. [4] In September 1950, a testbed Boeing B-17 Flying Fortress flew with a T34 turboprop mounted in the nose of the bomber.
