Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades.
The turbine blades have a golden colour in this engine cutaway. A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. [2] Each turbine disc has many blades. [3] As such they are used in gas turbine engines and steam turbines.
Compressor blades create a pumping action by working as airfoils. In a surge or stall, blades experience an aerodynamic stall (similar to an aircraft wing stalling) and become unable to hold back the higher pressure downstream, with a resulting violent flow reversal. The flame which is normally confined in the combustion chamber may come out of ...
The very first jet engines used centrifugal compressors and they are still used on small turbojets and turbo shaft engines. The key component that makes a compressor centrifugal is the centrifugal impeller which contains a rotating set of blades. In a centrifugal compressor the airflow goes perpendicular to the axis of rotation.
The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...
W.2B with longer turbine blades and using diffuser of W.2B Mark II and new blower case and turbine design to give 1,850 pounds-force (8.2 kN) at 16,750 rpm. First run in September 1942 attaining 1,755 pounds-force (7.81 kN). Sfc, 1.13 lb/(hr lbf) with jet pipe temperature of 606°C. Initially suffered from resonance at 14,000 rpm leading to ...
