ABSTRACT:
A short take off and landing (STOL) aircraft is optimized for STOL performance and flight at minimum airspeed. The aircraft includes leading edge wing slats that are extended and retracted under the direct manual control of the pilot. The aircraft further includes an aileron/flap mixing mechanism that automatically droops the ailerons when the flaps are lowered. A flap bellcrank, which pivots to lower the flaps, carries a pair of pulleys. Aileron control cables, that actuate an aileron bellcrank to raise and lower an aileron, are threaded around and between the two pulleys. When the flap bellcrank pivots to lower the flap, the pulleys vary the positions of the aileron control cables relative to each other to pivot the aileron bellcrank and thereby lower the aileron. The aileron control cables remain independently movable to maintain pilot control over the bank and roll of the aircraft. Preferably, the ailerons and flaps are drooped at different rates so that the aileron droop angle is approximately one-half of the flap angle. Preferably, lost most is provided so that aileron droop is minimized at small flap angles.
