Abstract

See full text

An improved thruster for propelling borescopes by the reaction forces generated by pressurized fluid expelled from the thruster has a desirably small cross-sectional profile made possible by its novel construction. The basic embodiment of the thruster comprises an elongated hollow cylinder sealed at one end by a bulkhead and supplied with pressurized fluid at the opposite, open end. A thin slot cut through the cylinder wall permits pressurized fluid to exit the hollow interior space of the cylinder, producing a reaction force useful in propelling a borescope tip to which the thruster is fastenable.
