GYROCOORDINATOR OF HOMING HEAD

摘要

FIELD: rocket engineering. SUBSTANCE: invention refers to homing heads used in control systems of artillery guided projectiles. Gyrocoordinator of homing head of artillery guided projectile includes rotor put on internal gimbal suspension. Its internal frame carries optical system. Front end face surface of rotor has ring supporting element. Collar made on threaded bushing is mounted with clearance with respect to supporting element in direction of action of launch acceleration. Bushing is attached to internal frame of gimbal suspension which outer diameter is bigger than internal diameter is bigger than internal diameter of ring supporting element. Value of clearance is determined from relation δ < Δ < δ+δ, where Δ is clearance value; d is maximum value of play of rotor bearings; dis value of zone of elastic deformations of rotor bearings. Rigidity of external frame in direction of rotor axle does not exceed value R/Δ, where Ris permissible action on bearings of gimbal suspension. EFFECT: increased impact strength of gyrocoordinator of homing head of artillery projectile by unloading bearings of rotor and gimbal suspension against inertial load of internal frame and elements mounted in it.
