Abstract

See full text

A hand held supersonic air knife with a supersonic variable flow nozzle yields a continuously variable power mass flow rate (CFM) and pressure over a selectable power range, responsive to rotations of the nozzle exterior sleeve or outer nozzle member. The maximum power position identified as one end position and a second end position as the lowest power. The exterior sleeve can be rotated to any axial or circumferential position between start (low) and end (high). The result will be an intermediate power position. Any intermediate position will also be a supersonic nozzle of varying parameters between the start and end positions. Thus, a variable flow supersonic nozzle is provided by the manual sleeve rotation by an operator or a remotely controlled positioning of the sleeve.
