1,152,587. Gyroscopes. S.G. BROWN Ltd. and N.J. MYALL. June 21, 1967 [June 22, 1966], No.27802/66. Heading G1C. A gyroscope includes a gyro rotor 10 mounted for rotation in a gaseous environment by means permitting angular displacement of the rotor spin axis from the axis about which the torque for spinning the rotor is applied and stationary means 44 adjacent the rotor arranged to promote the turbulence in the gaseous environment due to rotation of the rotor. In the embodiment described the rotor assembly 10 is constructed in accordance with Specification 1,148,582. The stationary means are in the form of radial ribs 44 connected to face 36 of the gyro casing 30. The outer rotor portion of the disc 10 is a gyro wheel 26 the outer surface of which is spherical about the centre of suspension of the gyro and has a pair of annular end faces 40 opposite the ribs 44. The ribs 44 increase the convergency time constant of the gyro i.e. they reduce the rate of return of the spin axis to coincidence with the drive shaft axis. |
