Abstract
Systems and methods are provided for an aircraft propulsor with a fan cowl with one or more tangential restraints. The tangential restraints may be configured to contact one or more tangential receiving portions of a fixed portion of the aircraft propulsor. The fan cowl may receive a load that may include a bending load. The tangential restraints may be configured to convert the bending load to membrane tension and thus decrease deflection of the fan cowl.
Claims20
An aircraft propulsor comprising:
- a core engine;
- a fixed nacelle portion circumscribing the core engine and comprising:
- a nacelle latch, and
- a tangential receiving portion;
- and
- a fan cowl configured to rotate around at least a first axis between an open position and a closed position, and comprising:
- a fan cowl latch configured to couple to the nacelle latch, and
- a tangential restraint configured to enter the tangential receiving portion as the fan cowl rotates around the first axis from the open position to the closed position, and configured to convert at least a portion of a radial load received by the fan cowl to membrane tension by contacting the tangential restraint when the fan cowl latch and the nacelle latch are coupled together.
