PLATE VII - GYRO - G.A.8


OPERATION OF THE GYRO - STEERING ENGINE

Air at 200 kilos pressure from the pressure reducer enters the gyro at (2) and passing through the boring in the piston enters the pressure chamber (12).  Before passing through the orifice (13) the air passes through a filter in the lead (2) which removes fine foreign particles.  About .25 to .28 seconds after the air enters the pressure chamber, pressure is built up to the point where the starting piston (3) is pressed down which in turn depresses the arm of (5) working aganst the spring (4). (5) activates the small pinion gear (14a) and the cam system connected with the pinion (14a) is operated, the end result being that the pin (18, fig. 2) is lifted out of its seat, releasing the gyro (8) which spins at 15,000 r.p.m.  Additional air at 6 kilos pressure enters through the line (1).  This also blows on the gyro and brings its speed up to 20,000 r.p.m.  At the same time air at 6 kilos pressure is fed from a branch of lead (1) to the nozzle (11) and c_____s the steering engine.
