摘要:
A miniature gyroscope having a gas-turbine reaction rotor of dumb-bell form which comprises a pair of masses (62, 63) one spaced from the other at opposite ends of a shaft, and an inner gimbal (61) which extends into the space between the two masses and there provides a rotational mounting for the rotor, and means (42) for feeding to the rotor, through the space between the pair of rotor masses, gas to be discharged from the rotor to cause it to spin.
un boîtier (1) un rotor (16) disposé dans ledit boîtier (1) un ressort à lame (68) spiralé susceptible de passer de l'état bandé à l'état débandé pour lancer en rotation ledit rotor (16) et dont l'une des extrémités (69) est liée audit boîtier (1) des moyens de blocage (32) de la rotation dudit rotor (16) des moyens de commande (39) des moyens de blocage (32) de la rotation dudit rotor (16).
Ledit gyroscope est remarquable en ce qu'il comporte:
un arbre (56) rotatif disposé coaxialement audit ressort (68) et susceptible d'être déplacé en translation, l'autre extrémité (67) dudit ressort (68) étant liée audit arbre (56), et des moyens d'accouplement (19, 59) dudit arbre avec ledit rotor (16), le désaccouplement dudit arbre (56) audit rotor (16) étant commandé par ledit ressort (68), lorsque celui-ci atteint son état débandé.

- La présente invention concerne un gyroscope comprenant : - un rotor creux (2) pouvant tourner autour d'un arbre fixe (3), - un ressort à lame (5) logé à l'intérieur du rotor (2), - des premiers et seconds moyens de liaison pour solidariser, respectivement, une première extrémité (6) du ressort (5) avec l'arbre fixe (3), et la seconde extrémité (7) du ressort (5) avec le rotor (2), pour pouvoir emmagasiner de l'énergie dans le ressort en le bandant, - la liaison qu'établissent lesdits premiers moyens de liaison étant rompue à la fin de la détente du ressort. - Selon l'invention, lesdits premiers moyens de liaison comportent un doigt (8), porté par l'arbre fixe (3), qui s'étend au moins sensiblement transversalement à l'arbre fixe (3) et est susceptible d'être engagé dans une ouverture (9) pratiquée dans ladite première extrémité (6) du ressort (5). - L'invention s'applique aux gyroscope.
摘要:
A guided projectile (11) is provided with a gyroscope (11) having a spherical rotor (41). The rotor (11) is supported at its outer spherical surface by a stator (42) using fluid bearing techniques. The stator (42) is fixed to the projectile's housing (38) so that the gyroscope (29) is operated in a strapdown mode. The structure of the gyroscope (29) and particularly the stator (42) places very little material along its center axis of the projectile (11). This is particularly useful where the projectile's warhead (17) functions by squiriting a stream (25) of metal through a target's armor, and any material in the way of the stream (25) would tend to diminish the lethality of the projectile (11). The spherical configuration of the rotor (41) and the use of the stator (42) as a support bearing also provides a method of supporting the rotor (41) during conditions of high acceleration which are experienced in cannon launch of the projectile (11). Other advantages include light weight, low cost and high reliability.
