Abstract
A front landing gear system for an aircraft including a swing arm rotatively coupled to a wheel, a forward link arm rotatively coupled to the swing arm, a oleopneumatic cylinder rotatively coupled to the swing arm, second extension arm and a bulkhead, a plate rotatively coupled to the bulkhead, an actuation device rotatively coupled to the bulkhead and to the plate, where refraction of the linear actuation device causes the plate and extension arms to move upward towards the bulkhead.
Claims15
A front landing gear system for an aircraft including:
- a swing arm rotatively coupled to a wheel;
- a forward link arm rotatively coupled to the swing arm;
- an oleopneumatic cylinder rotatively coupled to the swing arm, the forward link arm and a bulkhead;
- a plate directly and rotatively coupled to the bulkhead via a hinge with the oleopneumatic cylinder passing through the plate;
- an actuation device rotatively coupled to the bulkhead and to the plate,
- wherein retraction of the actuation device causes the plate, the forward link arm and the swing arm to move upward towards the bulkhead.
3 more elements
A method of operating a front landing gear for an aircraft including:
- rotating a base plate towards a bulkhead by actuating an actuator rotatively coupled to the bulkhead and the base plate;
- rotating an oleopneumatic cylinder passing through the base plate with the base plate directly and rotatively coupled to the bulkhead via a hinge towards the bulkhead as the actuator retracts;
- rotating a wheel coupled to the oleopneumatic cylinder by a first extension arm and a second extension arm towards the base plate thereby moving the wheel into a position the wheel would occupy if the oleopneumatic cylinder were compressed.
