METHOD OF CONTROL OF HYPERSONIC FLYING VEHICLE Russian patent published in 2004 - IPC

FIELD: rocketry and space engineering; control of inter-continental flying vehicles of sectional taper form.

SUBSTANCE: flying vehicle is set in mode of flat controllable ricocheting in passive section of trajectory at trajectory steepness of ± 2 deg. Prior to ricocheting, alternating reserve of static stability is imparted to flying vehicle at hypersonic speeds within working range of angles of attack from 0 to 30 deg. At the beginning of ricocheting, flying vehicle is turned by means of power plant in pitch channel at angle of attack of 15-20 deg. ensuring maximum aerodynamic efficiency at hypersonic speeds. Then, power plant is switched off when preset level of lateral g-loads is attained. Thus, subsequent ricocheting process is performed with the power plant switched-off at stable static position of flying vehicle at said angle of attack. As soon as conditions of attaining inter-continental range are achieved, engine plant is switched-on and pitch channel and flying vehicle is brought out of stable static position.

EFFECT: reduced power requirements for maneuverability and flying range due to avoidance of use of engine plant for orientation of flying vehicle in position of creating lifting force.
