Description
Technical field
The present invention relates to a kind of flexible solar battery battle array and method of deploying thereof of Shape-based interpolation memory composites.
Background technology
Along with increasing of spacecraft function, day by day improve the requirement of energy supply, solar array also progressively becomes large.But due to the particularity of aerospace industry, require that again spacecraft component must lightweight, take volume little.In this context, as the new direction of space solar cell development, flexible solar battery battle array film because of its quality light, foldable, the advantages such as large storage ratio must play its huge effect at the aerospace field in future.But existing little in the application of space solar cell about flexible solar battery battle array film, existence expansion control procedure is stable not, poor reliability, and flexible solar battery battle array film launches the not mature enough problem of Driving technique.
Summary of the invention
The object of the invention is to exist in the application of space solar cell launch that control procedure is stable not, poor reliability to solve existing flexible solar battery battle array film, flexible solar battery battle array film launches the not mature enough problem of Driving technique, and proposes a kind of flexible solar battery battle array and method of deploying thereof of Shape-based interpolation memory composites.
The flexible solar battery battle array of Shape-based interpolation memory composites, described flexible solar battery battle array comprises: one group of flexible solar battery unit; Each flexible solar battery unit comprises bracing frame, power supply main body, zone of heating and flexible solar battery battle array veneer, and one end of bracing frame is fixedly connected with power supply main body, the other end is free end, one side panel attachment zone of heating of bracing frame, the bonding one piece of flexible solar battery battle array veneer of heating layer surface; Zone of heating by power main body with power supply energy supply;
Wherein, support frame as described above comprises vertical structure and reinforcement layer, and vertical structure is one group of longeron arranged in parallel, and reinforcement layer is one group of reinforcement arranged in parallel, vertically between longeron with reinforcement fixes.
The method of deploying of the flexible solar battery battle array of Shape-based interpolation memory composites, vertical structure forms bracing frame with the horizontal mutual vertical arrangement of reinforcement, bracing frame surface attachment zone of heating, the bonding one group of flexible solar battery battle array veneer of heating layer surface, one end of bracing frame is fixed with power supply main body; By zone of heating, bracing frame is driven, control power supply main body with power supply be that zone of heating is powered, zone of heating heats up the vertical structure deliquescing that shape memory polymer composite material laminate is made, bracing frame is simultaneously curling until become web-like to bulk end of powering by free end with flexible solar battery battle array veneer, zone of heating is de-energized afterwards, stop heating, vertical structure cooling is hardening, obtains the flexible solar battery battle array veneer of web-like; After zone of heating heats up again, the flexible solar battery battle array veneer of the web-like of web-like returns to straightened condition, completes the expansion of the flexible solar battery battle array veneer of space web-like.
Beneficial effect of the present invention is:
The support frame structure that the present invention adopts shape memory polymer composite material laminate to make, therefore cover zone of heating on the surface in the side of bracing frame, obtain the bracing frame being coated with zone of heating; Then at the bonding flexible solar battery battle array veneer in bracing frame surface, the one end of the bracing frame being bonded with flexible solar battery battle array veneer is clamped and fastened on power supply main body, the other end is free end, obtains the flexible solar battery battle array veneer with launching Drive Structure.Application thermal drivers mode is carried out heat driven and is had and drive simple advantage, and the present invention can overcome complicated in mechanical structure, instability that Conventional pneumatic formula or mechanical space deployable structure exist, be subject to the defects such as impact failure.
The invention provides the method for deploying of a kind of flexible solar battery battle array in space, carry out heat driven by thermal drivers mode and then control heater intensification, the free end of bracing frame is curling to the stiff end of bracing frame, until flexible solar battery battle array single plate bending becomes web-like, cooling afterwards obtains the flexible solar battery battle array veneer being solidified into web-like; After zone of heating heats up again, the flexible solar battery battle array veneer of web-like returns to straightened condition, completes the expansion of spatial flexible solar array veneer.In expansion process, embody kinetic stability of the present invention and the high advantage of reliability, and it is low to have density, quality is light, the advantage that cost is low.Shape memory polymer composite material uses the character of material self to complete it and launches function, and only need settle heating element and do not need other actuators and mechanical mechanism, structure is simple.Due to shape memory polymer material stable in properties, launch mechanism simple, its expansion process reliability is high, relies on the deformation-recovery process of material to launch, so expansion process restoring force is steady.Owing to not having complicated actuator, as long as bearing structure is not destroyed under impact with concussion, mechanism just can carry out expansion and normally work.
