1,136,054. Training in missile firing. GIRAVIONS DORAND. 27 Feb., 1967 [17 June, 1966], No. 9152/67. Heading F3C. [Also in Division G2] In a device for maintaining an optical beam C, Fig. 1, parallel with a predetermined direction X, and particularly for providing a spot of light which simulates the trace of a missile in a weapon firing trainer, a gyroscope is provided whose rotor 15 has its spin axis 14 in the direction X and is mounted in inner gimbal 10 pivoting about axis Z in outer gimbal 9 which pivots about axis Y on a fixed member 20, the latter carrying a light source 1 for projecting a beam of light 3 on to a first mirror 4, carried by gimbal 9, in a direction A parallel to axis Y so that the beam is reflected along a path B parallel to axis Z to be reflected, at a second mirror 11 carried by gimbal 10, along the direction C. As applied to a weapon firing trainer, Figs. 2, 3 (not shown), the aiming telescope (25) views the target through a semi-reflecting mirror (24) which superimposes, by reflection, the beam C after reflection at a 45 degree mirror (22). A recording instrument or firing monitor (26) at right-angles to telescope (25) views the target by reflection at mirror (24) and the beam C by transmission therethrough. The gyroscope is normally caged by pin 16 and plunger 18 but at the instant of a simulated missile launching the plunger 18 is released to free the gyroscope. |
