| Abstract: | In the missiles which adopt IR imaging guidance system,J-T cryocooler is often used with the virtues of rapid performance and low cost.However,the air feed tube of J-T cryocooler causes disturbance torque which is exerted on the stabilized platform and then reduces the homing precision.In this paper,all kinds of the disturbance torques exerted on the platform are briefly analyzed first.Then,characteristics of the disturbance torque caused by the elastic air-feed tube are studied,and the calculating formulae are given.Based on the analysis above,practical methods are proposed in order to effectively reduce this disturbance torque. |
