In conjunction with Fig. 3, the excessively high folding angles that will lead in the position of strut 3 are small, too low to will lead to folding process and wing bottom wing
Face interference；5 stroke of pressurized strut is too long to occupy biggish wing space, influence wing structure safety, too short to will lead to folding
Angle is small.By adjusting the length of two pressurized struts 5, wing-folding process is simulated, kinematics analysis is carried out, optimizes needles of various sizes
And location parameter.Fig. 3 has intercepted 5 shapes that two pressurized struts connecting respectively with inner wing, outer wing 5 extend folding process simultaneously
State, according to folding time sequence respectively marked as A, B, C, D, E, wherein A is initial, expanded condition, and E is that final fold completes shape
State.
As it can be seen that mechanism of the invention can not destroy outside wing if not considering the interference problem of aircraft wing self structure
180 ° are folded under the requirement of shape, are suitable for the wing structure that all kinds of folding wings variant aircrafts, especially wide-angle fold.
The other parts of the present embodiment are same as the previously described embodiments, and so it will not be repeated.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is all according to
According to technical spirit any simple modification to the above embodiments of the invention, equivalent variations, protection of the invention is each fallen within
Within the scope of.
