Abstract

The invention provides an adjustable composite pressure-boosting air intake system which comprises two stages of pressure boosters, that is, an adjustable pressure booster and a turbine pressure booster respectively, wherein the adjustable pressure booster comprises a first-stage compressor, an air intake bypass valve, an acceleration mechanism, a driving device and an electronic control system; the first-stage compressor is connected with the air intake bypass valve in parallel; the first-stage compressor is connected with the acceleration mechanism; the acceleration mechanism is connected with the driving device; and the driving device is connected with the electronic control system. The rotation speed of the adjustable pressure booster can be correspondingly adjusted according to the change of altitude and engine speed, so as to realize reasonable distribution of the pressure ratio of the two stages of the pressure boosters and ensure the working efficiency. Therefore, by utilizing the system, the problem of recovering the power of a variable-altitude vehicle is solved.
