Definitions
- the invention relates to an arrangement for supporting and aligning antennas or telescopes, in particular for space applications, according to the preamble of patent claim 1.
- the weight for the arrangement for supporting and aligning the telescope can be significantly reduced.
- the alignment mechanism is based on changing the length of the six legs of the Hexapod. If the length of the legs can be changed over a wide range, the support and alignment arrangement, the hexapod, can also be used as an extension unit for extending the telescope. To do this, change the length of the six legs at the same time.
- the advantage of using a frame in the form of a hexapod not only to support and align a telescope, but also to use the frame as an extension unit, is that in applications with unfavorable satellite geometries, the telescope can be extended far and then no longer by other structures in its viewing angle is restricted on the satellite.
- a starting position is provided according to the invention in which the alignment mechanism is blocked in a defined manner (English: launch lock). According to the invention, this is achieved by internally bracing the individual legs.
- FIG. 1 An arrangement according to the invention, such as could be mounted on a satellite platform 2, is shown in FIG. 1.
- a telescope 1 is attached to a rigid support plate 10 via a rotation and deflection mechanism 5.
- the outline of the carrier plate 10 corresponds to an equilateral hexagon.
- An optical bench 3 is attached below the carrier plate.
- One end of a leg 6 is attached to each of the six corners of the carrier plate.
- the six legs are adjustable in length. They are each attached to the carrier plate 10 via a ball joint. At the other end, the legs 6 are combined in pairs and via ball joints with the satellite platform 2, which Base area forms, connected.
- the six adjustable legs form the hexapod frame.
- the structure of the individual legs can be seen in Figure 2.
- a leg 6 consists of an inner tube 8 and an outer tube 9.
- the inner tube can be moved with respect to the outer tube by piezoelectric linear motors 11. These are attached to the outer tube and move on the smooth, precisely machined outer surface of the inner tube 8. At each end of the legs 6 there is a ball joint 7.
- the legs are on one side with the satellite platform 2 and on the other side connected to the support plate 10 which carries the telescope 1.
- the inner tube 8 of the legs on the outer surface of which the piezoelectric linear motors, also called inchworm motors, move, is advantageously a PEEK tube and has a very good sliding surface.
- a stop disk 14 for the outer tube 9 At the lower end there is a stop disk 14 for the outer tube 9.
- the outer tube 9 is braced against the stop disk 14 by means of the piezoelectric linear motors.
- the surface of the stop disk 14 can be coated with steel wool, for example, in order to ensure high damping, friction and elasticity.
