Self-aligning low load shear out joint

A self-aligning support incorporates a support attachment fitting and a rotatable pin assembly having a primary load pin coupling the support attachment fitting to an attachment support, and inboard and outboard attachment claws engaged to end portions of the primary load pin. The rotatable pin assembly is configured to rotate relative to the support attachment fitting. At least one fuse pin extends through the primary load pin to limit translation of the primary load pin relative to the inboard and outboard claws.

Process and machine for load alleviation

A process and machine configured to predict and preempt an undesired load and/or bending moment on a part of a vehicle resulting from an exogenous or a control input. The machine may include a predictor with an algorithm for converting parameters from a state sensed upwind from the part into an estimated normal load on the part and a prediction, for a future time, of a normal load scaled for a weight of the aerospace vehicle. The machine may: produce, using a state upwind from the part on the aerospace vehicle and/or a maneuver input, a predicted state, load and bending moment on the part at a time in the future; derive a command preempting the part from experiencing the predicted load and bending moment; and actuate the command just prior to the part experiencing the predicted state, thereby alleviating the part from experiencing the predicted load and bending moment.

ACTUATION MECHANISM FOR CONTROLLING AIRCRAFT SURFACES
20220388631 · 2022-12-08 · ·

An actuation mechanism includes a control surface having a hinged end pivotally coupled to a wing structure, a first pivot arm and a second pivot arm coupled to the control surface, a first drive rod coupled to the first pivot arm, and a second drive rod coupled to the second pivot arm. A first bell crank is coupled via a first pivot pin to the wing structure at a first position and to the first drive rod. A second bell crank is coupled via a second pivot pin to the wing structure at a second position spaced apart from the first position and to the second drive rod. A coupling rod extends between the first bell crank and the second bell crank such that a rotation of the first bell crank is synchronized with a rotation of the second bell crank.
