GYROSCOPIC INSTRUMENT Russian patent published in 2003 - IPC

FIELD: control systems of artillery guided rockets. SUBSTANCE: proposed gyroscopic instrument includes cocked spiral propelling spring anchored with outer end in rim of rotor and with inner end releasibly connected to bushing-shaped part of base of gimbal suspension. Inner end of spiral propelling spring is connected through additional springy belt put on inner end of spiral propelling spring on its internal side. Rigidity of belt is 10-1000 times less than rigidity of spring and length is over 1.5 length of circumference of bushing-shaped part of base. Base of gimbal suspension has protrusion interacting with groove made in belt. EFFECT: simplified assembly of gyroscopic instrument with spring motor of high rigidity to accelerate rotor by reduction of adhesive force of spiral propelling spring to bushing-shaped part of base of gimbal suspension with preservation of required value of kinetic moment. 2 cl, 2 dwg
