SPACE VEHICLE LIGHT PROTECTIVE DEVICE

摘要

FIELD: space engineering; protection of optical and electronic devices against action of external thermal and light fluxes. SUBSTANCE: device consists of load-bearing frame and gates and electric drive kinematically linked with cover provided with movable doors and opening mechanism. Kinematic linkage is made in form of crank rocker arm mechanism which consists of crank drive rigidly fitted on shaft; one end of crank drive is connected with connecting rod and other end is articulated to rocker arm rigidly secured on cover axle. Length of connecting rod is determined from formula given in Description. EFFECT: enhanced efficiency.
