MULTIPLE-REFLECTOR ANTENNA FOR TELECOMMUNICATIONS SATELLITES

A multiple-reflector antenna for telecommunications satellites including a shaft (5), to which are attached at least two sub-reflectors (6, 7), rotating in relation to a load-bearing structure (2), and a motor (8) including a rotor (9) able to drive the shaft (5) in rotation, and a stator (10) attac...

Beschreibung
Zusammenfassung:	A multiple-reflector antenna for telecommunications satellites including a shaft (5), to which are attached at least two sub-reflectors (6, 7), rotating in relation to a load-bearing structure (2), and a motor (8) including a rotor (9) able to drive the shaft (5) in rotation, and a stator (10) attached to the load-bearing structure (2), characterized in that the multiple-reflector antenna (1) also includes two bearings (11, 12) enabling the shaft (5) to rotate in relation to the load-bearing structure (2), a torsionally rigid mechanical filter (13) placed between the shaft (5) and the rotor (9), enabling the rotor (9) to transmit the rotational movement to the shaft (5), and able to dampen the stresses generated by the shaft (5) on the motor (8), and locking means (14) able to hold the angular position of the shaft (5) in relation to the load-bearing structure (2).
