A ram-air intake is any intake design which uses the dynamic air pressure created by vehicle motion to increase the static air pressure inside of the intake manifold on an internal combustion engine, thus allowing a greater massflow through the engine and hence increasing engine power.
In this way, what is meant by ram effect?
: the compressing effect obtained by locating the entrance to an air-intake duct in an airplane in the air stream in such a manner as to take advantage of the relative velocity between the air intake and the air stream by increasing the static pressure in the system to aid in compressing the charge air or to maintain
What is a ram air parachute?
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag (or in the case of ram-air parachutes, aerodynamic lift). Parachutes are usually made out of light, strong fabric, originally silk, now most commonly nylon.
What is engine bleed air?
Bleed air produced by gas turbine engines is compressed air that is taken from the compressor stage of those engines, which is upstream of the fuel-burning sections. Some engine maintenance manuals refer to such systems as "customer bleed air".
