  • Patent number: 4735501
    Abstract: A method and apparatus for propelling a borescope being used to inspect inaccessible areas comprises one or more reaction jets attached to the borescope, the reaction jets expelling gas, liquid or other fluids to produce a reaction thrust force on the borescope. In one embodiment, a reaction jet is fastened to the remote head of an articulateable borescope, and the propulsion direction is controlled by an operator who views a desired aim point at the output end of the borescope cable, and articulates the borescope head to point at the desired aim point. In another embodiment, the orientation of the thrust vector of the reaction jets is controllable, permitting an operator to control the direction of travel of a borescope not necessarily possessing an independent articulation capability.
