Aircraft control surface (), in particular for an aircraft lifting surface (), that comprises a primary control surface () that comprises a hinge axis (), and a secondary control surface () that comprises a hinge axis (), with the secondary control surface () rotating by means of its hinge axis () relative to the primary control surface (), said secondary control surface () only partially occupying the span of the primary control surface (), the length of the secondary control surface () along its hinge axis () being significantly less than the length of the primary control surface () along its hinge axis (), and moreover the width or chord of said secondary control surface () along the direction of its hinge axis () narrows significantly towards the tip of the lifting surface () according to a law of narrowing designed expressly for adapting the distribution of torsional stiffness along the span of the lifting surface () to the distribution of aerodynamic load thereon, whereas the distribution of effective curvature due to the deflection of said control surface () is such that it increases the stalling angle of the lifting surface ().

Control surface of aircraft

Arrangement for mounting a propulsive system on an aircraft airframe by an external pylon which connects the engine with the airframe, the pyloncomprising a plurality of spars intruding into the airframe and units for attaching the spars to the internal airframe structure, the cited units being dampers, shock absorbers or active actuators with characteristics chosen so that the units are particularly suited for the efficient reduction of attachment and internal dynamic loads arising mainly but not only from hard landing events and aircraft flight manoeuvres, and for damping sustained vibrations of the propulsive system-airframe assembly, the arrangement allowing the easy removal of the pylonfrom the rest of the airframe and the interchangeability of the pylonbetween different aircrafts, being also the cited arrangement tolerant to damage or complete failure of at least one of the spars.
