ABSTRACT:
A floating speed electrically driven suction system for sucking boundary layer air flow off the external surface of an aircraft. A variable speed electrical generator drives a variable speed electrical motor which in turn drives a variable speed pneumatic compressor. Inlet guide vanes are automatically adjustable to compensate for variations in pressure. A surge control valve is operable to port in additional inlet flow as needed to avoid low volumetric surge in the suction compressor.
