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]
It was a Derwent Mark II turbojet engine with a cropped impeller (turbine unchanged) [2] and a reduction gearbox (designed by A A Rubbra) connected to a five-bladed Rotol propeller. The Trent ran for 633 hours on test before being installed in a Gloster Meteor jet fighter which flew for the first time on 20 September 1945 at the start of a 298 ...
However, despite the promising performance of the test engines Ernest Hives felt that pure-jets such as the Avon were the future and the Clyde programme was terminated, forcing Westland to use the less than satisfactory Armstrong Siddeley Python on the production Wyverns. [2] and so Rolls-Royce's first production turboprop would be the Dart.
As well as being one of the first engines to feature a free propeller turbine, the Theseus was the first turboprop in the world to pass a type test in January 1947. [3] Following 156 hours of ground runs and the receipt of a test certificate from the Ministry of Supply on 28 January 1947, two Theseus engines were fitted in the outer positions ...
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. [1] [2]
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]
