METHOD FOR QUALITY CONTROL OF FUNCTIONING OF AIR-DYNAMIC CONTROL ACTUATOR OF GUIDED MISSILE AND STAND FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: defense equipment, in particular, projectiles and missiles.

SUBSTANCE: the preliminarily cooled to the maximum preset negative temperature of the control drive is checked in a thermal vacuum chamber, when it is fed with air of a raised humidity. After the check a technical inspection of the drive (assemblies and parts) is carried out and the quality of coatings and insulation of the current-conducting circuits, strength, stability and serviceability are estimated. According to the results of the comparative estimate of the obtained values of the measured parameters with the preset ones in the selected conditions and technical inspection, a decision is taken on the quality of functioning of the air-dynamic control actuator cooled to the negative temperature at a compressed aid of a raised humidity. The stand for quality control of functioning of the air-dynamic control actuator of guided missile is provided with a thermal vacuum chamber with a vacuum pump, humidity chamber and a pneumatic cock with a connecting hose. The outlet of the humidity chamber is connected to the pneumatic cock and connecting hose to the inlet of the receiver. The base with the unit fastened on it and the receiver with the measuring pressure gauge and the relief valve are installed in the thermal vacuum chamber.

EFFECT: expanded potentialities of use of the stand and enhanced quality of control of functioning of air-dynamic control actuators and autopilots of guided projectiles and missiles.
