Air guide flap of an aircraft with the regulation of the pressure forces acting on it, a process for the position control system of an air guide flap and further with such an air guide flap

摘要

The present invention relates to an air guide flap of an aircraft, one of which an air duct surface facing toward the pressure prevailing in the air duct and the opposed face of the pressure of the on the aircraft is exposed to air flowing past. The air guide flap has an actuator for automatically opening and closing of the air guide flap, with a means for controlling the position of the air guide flap cooperates. In order to reduce the load of the air guide flap is kept low, a force detection means is provided which on the actuator on the basis of a difference between the pressure prevailing in the air duct and the pressure of the force acting on the aircraft air stream flowing past determined. The regulating device, the position of the air guide flap in such a way that the force acting in each case on the actuator is at least approximately zero.
