BEARING STRUTS OF TAKEOFF-AND-LANDING SHOCK ABSORBERS OF NON-EXPENDABLE SINGLE-STAGE LAUNCH VEHICLE

摘要

FIELD: non-expendable transport space systems of new generation (type KORONA).;SUBSTANCE: proposed struts belong to takeoff-and-landing shock absorbers of non-expendable launch vehicle. Struts are subjected to repeated gas dynamic and thermal action on side of launch vehicle engines in the course of operation. Struts are made from heat-resistant material; they are telescopic in form. Struts are retractable into and are extended from launch vehicle body in the course of launching and landing. No less than three struts shall be provided in takeoff-and-landing shock absorbers of launch vehicle. Each strut withstands load no less than launch weight of launch vehicle. Service life of these struts is about 100 flights at service life margin of 25%.;EFFECT: enhanced efficiency; increased service life of struts.;1 dwg
