Description
Technical field
The present invention relates to a kind of deployed configuration spare that is applied to space.
Background technology
Owing to be subjected to the restriction of the effective launch load and the emission volume of carrier rocket, be to have very little weight and very little emission volume for the requirement of the capacity weight that carries.Large-scale space structure all is in folded state when emission, form the state of its designing requirement after emission is entered the orbit by the mode of launching, and realizes its design function.The mode that existing deployed configuration mostly launches by machinery, this deployed configuration is the weight height not only, and folding efficiency is also less.In addition, in order to satisfy the requirement of survey of deep space, for the survey of deep space structure member of overlength, traditional frame mode is powerless especially.
Summary of the invention
Be the problem that solves the existing weight height of existing machinery deployed configuration, folding efficiency is less and can't makes up large space structure, the invention provides a kind of extra long aerated expansion supporting rod for outer space, it is mainly made up by membraneous material and forms, the present invention includes the termination lid of inner layer pipe, outer tube and two tubulars, inner layer pipe is put in outer tube, the center of each termination lid has air-filled pore, and two termination lids are connected by sealing with the two ends of inner layer pipe and outer tube respectively; The length L of strut bar is 10～100m; Inner layer pipe and outer tube are membraneous material.Inner layer pipe of the present invention and outer tube adopt membraneous material, adopt the mode of curling to fold, and are in folded state when putting into the rocket load compartment, after emission enters space, the air-filled pore that covers by the termination charges into gas to tube interior, and strut bar fully launches, and reaches mode of operation.The present invention can be used for the isostructural expansion driver train of sun shade of large aperture antenna, solar sail, solar energy sailboard, super long type one pole and dipole antenna, satellite truss structure, large-scale high-precision optical mirror; Also can be used as structure member and use, be used for support cameras and other load; On ground, the present invention can be used for the support of interim advertising lamp box and at the aspects such as support of the protruding antenna of the landform of complexity zone provisional communication.
Outstanding advantage of the present invention is: one, it is mainly made up by membraneous material and forms, and in light weight, simple in structure, it is convenient to connect with other structure.After vacuumizing, adopt efficient folding mode can occupy very little storage volume, the inflation back is deployable, has in light weight and the high advantage of folding efficiency.Two, because single, the no joint of tubing so just can realize that failure-free launches, expansion process is easy to control simultaneously.Three, can carry out corresponding structure design according to the requirement of different expansion propulsive effort, duration of run, mechanical property and version, satisfy different operatings needs, have stronger designability, Applicable scope is very wide.Four, can realize the making of overlength, reach up to a hundred meters length, thereby satisfy the requirement of survey of deep space.
