COMPRESSOR GASDYNAMIC SUPERCHARGE SYSTEM Russian patent published in 2011 - IPC F04B39/00 F24F13/02 

FIELD: engines and pumps.

SUBSTANCE: proposed system comprises inlet pipeline with air flow temperature gage, air cylinder with spring-loaded piston provided with tie rod connected with pipeline before elastic section along inlet airflow, and gage control unit. Pipeline inner surface is provided with curved guides with curvature of positive screw line rotation direction after elastic section. Pipeline inner surface is provided with curved guides with curvature of negative rotation direction before elastic section. Pneumatic cylinder piston underside chamber communicates intermittently with source or atmosphere via electrically driven three-way valve. Transducer control unit incorporates electric drive rpm controller made up of electromagnetic couplings and electronic control system including temperature controller incorporating connected comparator, setter and nonlinear communication circuit, as well as electronic and magnetic amplifiers. Electronic control system is connected with airflow temperature controller Inlet pipeline section, up to elastic section, is made of bimetal. Bimetal material inner surface features thermal conductivity factor 2 to 2.5 times higher than that of bimetal material outer surface.

EFFECT: rated efficiency in variable ambient conditions
