Axial-flow compressor
Aerospace; Control systems
One in which the air is compressed parallel to the axis of the engine. It is made up of a series of alternating rotor and stator vane stages.
Boss
Aerospace; Control systems
Raised rim around a hole; e.g. axle hole in a wheel. Circular projection on a casting, usually serving as the seat for a bolt head or nut.
Atmospheric pressure
Aerospace; Control systems
Barometric pressure exerted by the atmosphere as a result of gravitational attraction above the point in question.
Atomizer
Aerospace; Control systems
Nozzle that creates minute particles and accurately shaped spray of fuel suitable for rapid mixing and combustion.
Bending
Aerospace; Control systems
Combination of tension and compression. The inside curve is under compression; the outside is under tension.
Bleed system
Aerospace; Control systems
Device that unloads small amounts of air to relieve pressure.
Primary air
Aerospace; Control systems
Air that mixes with fuel in the combustion chamber to form a combustible mixture. The ratio is 15 parts of air to 1 part of fuel.
