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-powered", this is more commonly by use of a turboshaft engine, a development of the gas turbine engine where an additional turbine is used to drive a rotating output shaft. These are ...
His invention had most of the elements present in the modern day gas turbines. The turbine was designed to power a horseless carriage. [5] [6] 1894: Sir Charles Parsons patented the idea of propelling a ship with a steam turbine, and built a demonstration vessel, the Turbinia, easily the fastest vessel afloat at the time.
Turboprop engines are jet engine derivatives, still gas turbines, that extract work from the hot-exhaust jet to turn a rotating shaft, which is then used to produce thrust by some other means. While not strictly jet engines in that they rely on an auxiliary mechanism to produce thrust, turboprops are very similar to other turbine-based jet ...
Some large turboprop engines, such as the original Bristol Proteus and the modern TP400 have free turbines. The TP400 is a three-shaft design, with two compressor turbines and a separate power turbine. Where the turbine is at the rear of the engine, a turboprop engine requires a long drive shaft forwards to the propeller reduction gearbox. Such ...
The propelling nozzle converts a gas turbine or gas generator into a jet engine. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). [18]
A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction system, and the shaft ...
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 Rolls-Royce RR500 is a family of small gas turbine engines developed by Rolls-Royce Corporation. The RR500TP turboprop variant was intended for use in small aircraft. The RR500TS was the turboshaft variant designed for light helicopters. Development of the RR500 was abandoned in 2012.
