Compressor Operation

In a jet engine, there are two modes of compressor operation which have to be considered: 1) stationary mode, where engine parameters do not change (cruising flight); 2) transient mode, where engine parameters quickly change, with the engine accelerating to maximum thrust.Stationary mode, or steady-state,...

Rotating Stall and Surge

The rotating stall and surge in axial flow compressors are among the most serious problems in turbomachinery aerodynamics. They directly affect the thrust necessary to propel an aircraft at an adequate speed or to drive a generator in AC generation. Both phenomena have to do with the axial flow, and the flow in a multi-stage axial flow compressor is complex in nature because of the proximity of moving...

Bristol Mercury IX

The Bristol Mercury IX was a British radial engine used as the power plant for the Gloster Gladiator Mk I, the Fokker D.XXI, and the Bristol Blenheim. Developed from the Bristol Jupiter, it was conceived and produced to power small and medium size aircraft, such as fighters and small bombers. The Bristol...

Union Pacific 4014

The Union Pacific 4014 'Big Boy' is the largest steam locomotive in operation in the world today. It delivers 7,500 horsepower at drawbar, and 8,300 HP at cylinder. It can travel at the top speed of 80 mph (130 km/h) on standard gauge railway track (1.435 m). It runs as a chartered train for the Union...

Volvo Flygmotor RM6C

The Volvo Flygmotor RM6C was a turbojet engine developed from the British Rolls Royce Avon 300 machine. It was built in Sweden in large numbers, under license, to power the Saab J35 Draken combat aircraft. It was a powerful and reliable engine, capable of delivering 17,700 pounds of thrust, enabling...

Jet Engine Rotor

The jet engine rotor is a rotating spool which turns airfoils-containing disks around at high speed. It compresses incoming air from the air intake and converts the hot gas flow from the combustion chamber into mechanical shaft power, called torque. Thus, the rotor of a jet engine is essentially composed...

Siemens SST-700

The Siemens SST-700 is a dual-casing, geared, high-pressure steam turbine. Designed and produced by Siemens, it is employed for alternating current generation at gas/biomass combined cycle and solar-thermal power plants. It is composed of a geared high pressure (HP) turbine module and a low pressure...
