Claims20
A method for implementation of a kicked spar, the method comprising:
- determining a desired chordwise length to accommodate an actuator component along a forward edge of a control surface;
- and
- forming a bend in a spar of the control surface, the bend providing an offset corresponding to the desired chordwise length, the spar having a web profile with inflection points.
A method for implementation of a kicked spar, the method comprising:
- determining a chordwise length to accommodate a component along a forward edge of a control surface;
- forming a plurality of bends in a spar to define a region that is offset from a hingeline of the control surface by the chordwise length;
- and
- extending the spar along at least a portion of the forward edge of the control surface.
