ABSTRACT:
A technoscope for internal inspection of plant such as special aircraft power units equipped with non-circular, preferably cornered (e.g. square) wall ports comprises a rigid first metal guide shaft of non-circular cross-section insertible into one of the wall ports and having a lateral distal outlet guide, and a guiding element which passes through said first guide shaft and has a flexible distal portion, an intermediate portion whose cross-section matches that of the first guide shaft and a proximal control system for controlled deflection of said flexible distal end. The guiding element is used to guide a flexible endoscope shaft to the desired site within the plant to be inspected.
