    摘要: Inside a ducted fan turbine engine, especially one with a high or very high bypass dilution ratio, access to the gas generator compartment of the engine is effected by means of two articulated caps (34) with a C-shaped section. The upper edge of each cap (34) is connected to the fixed structure of the jet engine by means of a series of articulated arms (36) and a telescopic link (54) is inserted between the housing of the engine and the bottom of each cap. In a first stage (arrow F1), this mechanism enables the caps (34) to be brought beyond the rear edge of the outer ring (12) of the jet engine, the links (54) being locked in a compressed position. In a second stage, the caps (34) uncoupled from the ring (12) are able to pivot from the desired angle (arrow F2) around an axis (y-y') parallel to the axis (x-x') of the ducted fan turbine engine.
