The course of work of the invention:
When wing needs to move backward, outer skeleton electric heating mechanism heats skeleton outside marmem, works as shape After the outer skeleton temperature of memorial alloy rises to the outer skeleton deformation temperature of marmem, the outer skeleton of marmem starts shape Become, completes wing and deform backward.When needing to restore shape after wing completes deformation backward, inner frame electric heating mechanism is to shape Shape memory alloys inner frame heating, when marmem inner frame temperature rises to skeleton deformation temperature outside marmem Afterwards, marmem inner frame starts deformation, and wing restores shape.
Beneficial effects of the present invention:
1, using marmem as wing skeleton, by skeleton Resistant heating tune inside and outside marmem Save marmem frame configuration.Respectively inside and outside skeleton trains shape memory, skeleton inside and outside thermal drivers, and inside and outside skeleton is mutual Wing front and back deformation is completed for driving.
2, deformation before and after the achievable wing of the present invention, is driven without complicated machinery, only leans on marmem skeleton Realize wing deformation.Compared with traditional fixed-wing aircraft wing, have the function of wing shapes deformation, aircraft can be made to adapt to different air dynamic Force environment, enhancing aircraft fly control performance, and it is excellent to have that wing structure is simple, light weight, development cost is low, maintenance cost is low etc. Point.
3, the tradition machinery movement for eliminating each discrete trailing edge, to reduce resistance and noise, while improving energy Utilization efficiency is measured, is beneficial to energy conservation.
4, the present invention is applicable not only to fixed wing aircraft, can also widen to forces with fixed-wing such as submarine, cruise missiles Device system, the environment for improving weapon system accommodate controllability, reduce manufacture and maintenance cost when weapon is on active service.
