Controlled internal flap for variable section tail pipe of turbo shaft engine of military aircraft, has connecting unit extending entirely on side of external face of flap plate such that unit is isolated from propulsion gas by flap plate

摘要

The flap has a flap plate (26) including an internal face that delimits a propulsion gas flow space. An operating lever has a fixing part for fixing the plate to the lever and a connecting part for connecting the lever to a control cylinder that rotates a controlled flap (16). The flap has a connecting unit (46) formed with a plate (48), blind orifices (58) and connecting rods (68) for reversibly connecting the flap plate with the fixing part. The connecting unit extends entirely on a side of an external face (32) of the flap plate such that the unit is isolated from the gas by the plate.
