2. Compressor map - Wikipedia

   en.wikipedia.org/wiki/Compressor_map

   Compressor surge is a particular problem during slam-accelerations and can be overcome by suitable adjustments to the fueling schedule and/or use of blow-off (bleeding air off the compressor, for handling purposes). In the particular example shown, a slam-acceleration from ground idle would cause a high-pressure compressor surge.

3. Components of jet engines - Wikipedia

   en.wikipedia.org/wiki/Components_of_jet_engines

   Low pressure (40–70 psi or 280–480 kPa), high volume air from the compressor section of the APU is bled off through a system of pipes to the engines where it is directed into the starting system. This bleed air is directed into a mechanism to start the engine turning and begin pulling in air.

4. Rotary-screw compressor - Wikipedia

   en.wikipedia.org/wiki/Rotary-screw_compressor

   Principal view of the pumping action of a twin-screw pump with a six-lobe female screw and a five-lobe male screw. A compressor (as opposed to a pump) would be shaped the same way, except that the shape of the lobes would change along the length of the screw, so that the volume of the trapped pockets would get squeezed smaller as they get closer to the exhaust port.

5. Bleed air - Wikipedia

   en.wikipedia.org/wiki/Bleed_air

   Bleed air in aerospace engineering is compressed air taken from the compressor stage of a gas turbine, upstream of its fuel-burning sections.Automatic air supply and cabin pressure controller (ASCPC) valves bleed air from low or high stage engine compressor sections; low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting ...

   Time Model – Tin Wizard – High quality 1:43 scale metal models made in Germany. TK.company – Same as Ignition_Model & IG-Model. Tokyo Marui – Japanese manufacturer who briefly made plastic model car kits. Tomte Laerdal – Norwegian brand of 1:43 scale soft plastic toy cars using dies of old Dinkys and sometimes Tekno [89]

7. Centrifugal compressor - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_compressor

   The simplest inlet to a centrifugal compressor is typically a simple pipe. Depending upon its use/application inlets can be very complex. They may include other components such as an inlet throttle valve, a shrouded port, an annular duct (see Figure 1.1), a bifurcated duct, stationary guide vanes/airfoils used to straight or swirl flow (see Figure 1.1), movable guide vanes (used to vary pre ...

8. Pneumatic motor - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_motor

   A pneumatic motor (air motor), or compressed-air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed-air energy to mechanical work through either linear or rotary motion.

9. Variable-speed air compressor - Wikipedia

   en.wikipedia.org/wiki/Variable-speed_air_compressor

   If a variable speed drive compressor operates continuously at full speed, the switching losses of the frequency converter result in a lower energy efficiency than an otherwise identically sized fixed speed compressor. Where demand remains constant within 5–15% of the total free air delivery flow rate, dual-control compressors configured in a ...
