ABSTRACT:
A spoileron control mechanism is shown which provides for separate or simultaneous braking and rolling of the aircraft through operation of spoilers located on the wings. The control mechanism includes a base to which is mounted two pivot brackets 2. Pivotally mounted to the base are two bell cranks 3 to which are connected via cables 15 to the spoiler. The bell cranks are pivoted in a scissors like fashion by connection via arms 7 to slotted plates 5 that are also pivoted side to side by a control stick 13 which causes the bell cranks to operate the spoilers in a differential fashion for roll control. The bell cranks are further actuated by a lever 10 which causes a cam bar 8 to act on the arms 7 pivoting the bell cranks and causing the spoilers to be actuated simultaneously for braking of the aircraft.
