A structure of a control surface for aircrafts, such as elevators, rudders, landing flaps, ailerons, and other similar lifting surfaces. The control surface includes a front spar, a rear spar, a plurality of ribs, at least one hinge fitting, and at least one actuator fitting, the hinge and actuator fittings joined with the front spar. A first rib is joined with a hinge fitting to form a first oblique angle with the front spar; a second rib is joined with an actuator fitting to form a second oblique angle with the front spar. The rear spar, located between the front spar and trailing edge of the control surface, extends only between the second rib and an outboard end of the control surface. The ribs are located in correspondence with the main torsion and bending load paths created in the control surface during flight, landing or takeoff.
An aircraft control surface that extends between an inboard end and an outboard end, the aircraft control surface comprising:
The aircraft control surface according to any of the preceding claims, wherein any pair of two adjacent ribs arranged within an interior region of the control surface, are obliquely arranged with respect to the front spar in opposite inclinations, and wherein said interior region extends from the inboard end to an intermediate point between the inboard end and the outboard end of the control surface.
An aircraft control surface that extends between an inboard end and an outboard end, the aircraft control surface comprising:
