Angle is directly related to the angle of windsurfing and sunray, so influence too can windsurfing generating efficiency.Especially as two dimension
The solar energy sailboard of Direct to the sun is rotated, the size of outspreading sailboard is more much larger than satellite body, and expanded angle is 180 °, sail
The planarization of plate expansion not only influences the control of the attitude of satellite, meanwhile, also influence the generating efficiency of windsurfing, it is therefore desirable to effectively control
The holding of outspreading sailboard angle and angle processed.
The expansion and locking of solar panels in the prior art drive outspreading sailboard by using motor or spring mostly, lead to
Tensile force or the special construction of spring are crossed to lock the expanded angle of windsurfing.Being unfolded using motor and lock windsurfing can be not only
Increase the weight of satellite, structure is complicated, and will increase the complexity of control system, and general windsurfing is all that disposable exhibition opens and locks
Tightly, gathering or swing angle are no longer needed to, so being unfolded and locking the occasion that windsurfing is served only for particular/special requirement using motor.
Driven using spring outspreading sailboard be comparison directly and simple method, but lock how is realized by spring
Be tightly it is relatively difficult, usually the driving force of spring is selected it is sufficiently large, while guaranteeing that windsurfing can be unfolded it is remaining enough
Tensile force lock windsurfing, but how this driving force and remaining tensile force are chosen is more complicated, if driving
The sum of power and remaining tensile force are too big, then windsurfing will receive biggish tensile force when collapsing and damage windsurfing, open up simultaneously
Satellite will receive biggish impact when opening, if too small, windsurfing cannot be deployed into expected angle.
For skin Nano satellite, solar panels expansion and locking device are as simple as possible, and are unfolded and lock process
It needs to stablize, therefore is preferred using traditional spring driving and locking mode, but how to realize effective knot of driving and locking
Conjunction needs to redesign structure, to solve deficiency when conventional springs driving and locking, is normally unfolded in guarantee windsurfing
While, moreover it is possible to the effective locking for realizing windsurfing, increased structure cannot additionally increase installation space and weight, and require to tie
Structure is simple, reliable for operation, can quick, simple realization windsurfing gathering and expansion locking.
