The inventive solar wind-driven craft relates to space engineering, more specifically to the structural design of a solar wind-driven craft using a solar light pressure for motion control. Said invention makes it possible to substentially increase the thrust of the solar wind-driven craft and a payload mass by reducing the specific load of the craft per unit area of the surface thereof. The essence of the invention lies in that in a known wind-driven craft consisting of a body, a main and additional ring-shaped reflective surfaces and means for the formation thereof which comprise a spin device, means for controlling the orientation of flexible reflective surfaces are provided with a gimbal suspension on which the spin device and corresponding formation means which are embodied in the form of a pneumatic system and comprise concentric air chambers and radial struts are mounted. In addition, said air chambers and radial struts are embodied in the form of a flexible pipe which comprises equidistantly disposed valves provided with holes to which interacting pneumatic toroidal or ball-shaped cells are spliced. Said valve comprises a tube provided with two radial holes and a spring-loaded ball which is arranged inside said valve and interacts with a compressed air contained in the flexible tube cavity. In the second variant, the valve comprises two elastic mutually perpendicular strips interacting with the ball. The balls can be made of a low-melting material (for example a plastic material) and comprise spirals which are arranged thereinside, made of a high electrical resistant material (for example nichrome) and serially connected to each other and to a voltage source by means of an electric wire. The spin device is embodied in the form of a hoop which is arranged on the external frame of a mantel suspension in such a way that it is rotatable and interacting, by means of a wheel, with a newly introduced third electric motor. A pneumatic system for forming a reflective surface is arranged on the hoop and pneumatically connected, through a sealed channel which is arranged in the external frame of the gimbal suspension, to a pressurised gas source disposed in the craft body. The second embodiment of the spin device comprises rotor and stator coils which are disposed on the external frame of the gimbal suspension and on the hoop, respectively and interact therebetween. The stator coil ends and the rotor coil ends are connected to the voltage source through rotatable concentric rings mounted on the electric rings thereof and through brushes which are fixedly connected to the external frame of the gimbal suspension. |
