Abstract
A system for inspecting internal zones of a machine, such as an engine, comprises an observation device having an optical fiber endoscope, and distribution and guide means including a network of flexible guide sheaths placed in the machine to define a number of different inspection routes along which the endoscope can be guided from an aperture in the machine wall to various predetermined critical internal zones. Preferably the system includes first electrical means implanted in each guide sheath and co-operable with second electrical means secured to the endoscope in order to detect the position thereof in the network and to transmit the position to a monitoring device outside the machine for monitoring and assisting the guidance of the endoscope in the network.
