FLYING PROCESS AND DEVICE OF AN AIRCRAFT OPTIMIZING THE CONTROL OF AILERONS IN A HIGH-LIFT CONFIGURATION

摘要

The method involves conferring a lift configuration to wings on which ailerons are fixed. The ailerons are in negative upward deflection (b0) by an angle so that the ailerons partially preserve their rolling efficiency when an attack angle and a speed of an aircraft are lower than an attack angle threshold (alpha s) and higher than a speed threshold (Vs), respectively. The ailerons, otherwise, are in positive downward deflections (b1, b2) relating to a maximal fineness and an optimal lift, if the aircraft is in take-off or re-ascent phases and a landing phase, respectively. An independent claim is also included for a device for implementing a method for flight controlling of an aircraft.
