propulsion engine inlet flap for application to the air inlet of an aircraft propeller engine as well as propellant inlet and engine system inlet flap

摘要

powertrain intake flap for application to the air inlet of an aircraft powertrain as well as powertrain inlet propeller flap and aircraft system. The present invention relates to a propeller inlet flap (k) for application to an air inlet or air inlet port of an aircraft propeller mechanism with a first end (e1) and a second end (e2) positioned opposite that and spaced in a longitudinal direction (l) of the intake flap, the longitudinal direction (l) when the intended use is directed against the aerodynamic direction (s) of air flowing into the mechanism - an inlet flap base body (1) with a connection device for a hinged joint for hinged connection of the intake flap base body (1) in the air inlet housing or inlet channel with an axis of rotation (a) extending along the second end (e2), an inlet flap extension portion (2) structure integrally with the inlet flap base body (1), which has a pri first and a second side portion (5, 6) extending respectively at the two mutually opposite opposite side edges (1a, 1b) and extending in the longitudinal direction (1) of the inlet flap (k) of the base body of the intake flap (1), with a plurality of transverse struts (11) or longitudinal struts disposed in the forward region of the drive mechanism inlet flap (k).
