Diffuser section: - The diffuser slows down the compressor delivery air to reduce flow losses in the combustor. Slower air is also required to help stabilize the combustion flame and the higher static pressure improves the combustion efficiency .
When the diffuser discharges into an annular bend the collector may be referred to as a combustor inlet (as used in jet engines or gas turbines) or a return-channel (as used in an online multi-stage compressor). As the name implies, a collector's purpose is to gather the flow from the diffuser discharge annulus and deliver this flow downstream ...
Diffuser (automotive), a shaped section of a car's underbody which improves the car's aerodynamic properties Part of a jet engine air intake , especially when operated at supersonic speeds The channel between the vanes of the stator of a centrifugal compressor
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.
An inlet cone, as part of an Oswatitsch-type inlet used on a supersonic aircraft or missile, is the 3D-surface on which supersonic ram compression for a gas turbine engine or ramjet combustor takes place through oblique shock waves. Slowing the air to low supersonic speeds using a cone minimizes loss in total pressure (increases pressure recovery).
The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727.It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft.
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
The Power Jets W.2 was a British turbojet engine designed by Frank Whittle and Power Jets (Research and Development) Ltd.Like the earlier Power Jets W.1, the reverse-flow combustion configuration included a double-sided centrifugal compressor, 10 combustion chambers and an axial-flow turbine with air-cooled disc.
