METHOD OF CONTROL OF AERODYNAMIC LOADS ACTING ON AIRCRAFT COMPARTMENTS AND DEVICE FOR REALIZATION OF THIS METHOD (VERSIONS) Russian patent published in 2000 - IPC

FIELD: rocketry. SUBSTANCE: method is based on change of pressure of gas medium in compartment relative to pressure on its surface through efflux of gas medium from compartment at action of aerodynamic flow. Change in pressure inside compartment is preliminarily determined by the flight trajectory. Efflux of gas medium is effected to local zone of surface at outside pressure equal to pressure inside compartment in mode of maximum pressure drops in the flight trajectory. In some versions, device have drainage holes whose positions are selected taking into account gradient of change of outside pressure in the flight trajectory; effective area is selected taking into account volume of compartment occupied by gas medium, flow coefficient of drainage hole and maximum drop of pressure between cavity of compartment and outside pressure. EFFECT: enhanced strength. 4 cl, 9 dwg
