The first British turboprop engine was the Rolls-Royce RB.50 Trent, a converted Derwent II fitted with reduction gear and a Rotol 7 ft 11 in (2.41 m) five-bladed propeller. Two Trents were fitted to Gloster Meteor EE227 — the sole "Trent-Meteor" — which thus became the world's first turboprop-powered aircraft to fly, albeit as a test-bed ...
György Jendrassik worked on gas turbines and in order to speed up research, he established the Invention Development and Marketing Co. Ltd. in 1936. Following the successful running of a small experimental gas turbine engine of 100 bhp output in 1937, began to design a larger turboprop engine, which would be produced and tested in the Ganz works in Budapest.
The General Electric XT31 was first used in the experimental Consolidated Vultee XP-81. [4] The XP-81 first flew in December 1945, the first aircraft to use a combination of turboprop and turbojet power. The XC-113, with T31 in the No. 2 position. The T31 engine was the first American turboprop engine to power an aircraft. [5]
The Walter M601 is a turboprop aircraft engine produced by Walter Aircraft Engines of the Czech Republic. The company's first turboprop, the M601 is used in business, agricultural and military training aircraft.
It was designed to be both a turboshaft (TSE331) [8] and a turboprop (TPE331), but the turboshaft version never went into production. The first engine was produced in 1963, installed on the Aero Commander in 1964 and put into production on the Aero Commander Turbo Commander in June 1965. [citation needed]
The T56 turboprop, evolved from Allison's previous T38 series, [3] was first flown in the nose of a B-17 test-bed aircraft in 1954. [3] One of the first flight-cleared YT-56 engines was installed in a C-130 nacelle on Lockheed's Super Constellation test aircraft in early 1954. [5]
Engine starting was by cartridge. The Ministry of Supply designation was ASMa (Armstrong Siddeley Mamba). The ASMa.3 gave 1,475 ehp and the ASMa.6 was rated at 1,770 ehp. A 500-hour test was undertaken in 1948 [1] and the Mamba was the first turboprop engine to power the Douglas DC-3, when in 1949, a Dakota testbed was converted to take two Mambas.
Its first bench run took place in 1940, making it the world's first turboprop engine to run. However, combustion problems were experienced which limited the output to around 400 bhp. Development was discontinued in 1941, when an agreement was reached to manufacture the Daimler-Benz DB 605 engine in Hungary. [2] [3]
