Abstract: A solar sail spacecraft is designed to steer and move in space by using solar radiation pressure as a driving force, therefore allowing fuelless propulsion, station keeping and attitude control. A solar power satellite utilizes thrusters only to stay in an rather stationary orbit. Its purpose is, to collect energy and transfer it to a given location, usually to Earth. The intention of the present invention is to create a hybrid of a solar sail spacecraft and a power satellite for space based power generation and transmission, which is mobile and provides both, fuelless solar sailing and electric thrusters as means of propulsion. The mobile Solar Sail Power Station serves as solar energy collector and can be connected by docking with other power stations and with a transmitter unit for energy transmission, whereby the transmitter features its own fuelless pointing and attitude control devices.

Abstract: This invention concerns a mechanical friction device (10), in particular a brake or clutch disc. The friction device (10) includes a central layer (16) which is sandwiched between two outer, friction layers (18.1, 18.2). The central layer (16) has a porosity level higher than that of the two friction layers (18.1, 18.2). The central layer (16) is in the form of a wire-frame structure (30, 40) which acts as heat transfer means to transfer heat away from the friction surfaces of the outer, friction layers (18.1, 18.2). In the preferred embodiment the wire-frame structure is either an X-type lattice sandwich structure (30) or a wire-woven bulk diamond structure (40). This invention also concerns the use of wire-frame structure as a heat transfer means in a mechanical friction device (10) such as a brake or clutch disc.
