Title: Improvements in and relating to aircraft
IPC: B64C21/08
Filed: 1953-07-16
Abstract: 727,002. Aircraft control surfaces. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU NORD. July 16, 1953 [July 16, 1952], No. 19794/53; Class 4. An arrangement of landing flaps for an aircraft, of the type having an ordinary flap and an auxiliary flap pivoted to the banking aileron, is characterized in that the auxiliary flap is operatively connected to the flap so as to be displaced by the latter when operated by the pilot. Referring to Fig. 3, an ordinary flap 6 is pivoted on brackets 5 at the inboard end of the trailing edge of a wing 2. An aileron 8 is similarly mounted outboard on an axis W-W and is shaped to receive an auxiliary flap 10 pivoted to the aileron by hinges 11. A member 18 fast to the ordinary flap 6 rocks a two armed lever 13, 13a by a rod 12, and a rod 15 pivoted to arm 13a abut an axis Z-Z is pivotally attached to the auxiliary flap 10. Actuation of the ordinary flap by the pilot also lowers the auxiliary flap by means of the linkwork described. The assembly is preferably such that when the flaps are up, axis Z-Z coincides with axis W-W, so that operation of the aileron does not affect the position of flap 10 relative to the aileron. When the flaps are down, axis 2-2 is displaced so that displacement of flap 10 relative to the aileron increases as the aileron is raised and vice versa. If axis W-W and Z-Z do not coincide when the flaps are up, it is necessary to leave an angular gap between flaps 10 and the aileron, which will be closed when the aileron is lowered or raised, according to the linkwork geometry.
