METHOD OF THERMOSTATTING OF ITEMS LOCATED IN SUCCESSION IN COMPARTMENTS OF LAUNCH VEHICLE NOSE CONE Russian patent published in 2007 - IPC B64G1/50 B64G5/00 

FIELD: rocketry and space engineering; thermostatting of payload and instrument compartment located in launch vehicle nose cone.

SUBSTANCE: proposed method includes injection of thermostatting medium into compartments of nose cone for flowing along length of compartment and escaping into atmosphere. In the course of injection, heat generation sources are disconnected in way of flow of thermostatting medium. Then, temperature of surface and temperature of gas is measured till required level has been obtained. Effective temperature of gas medium is determined by temperature of surface of item. Then, thermostatting medium is again injected into compartment at additionally disconnected heat generation source of previous flow of thermostatting medium at temperature which is not equal to effective temperature and previous procedures are repeated. Required parameters of heat transfer are determined by temperature on item surface with the use of data on rated mass and heat capacity. On basis of comparison of internal heat release of item with heat picked up on its surface, operating parameters of injection at compartment inlet are noted.

EFFECT: enhanced accuracy of determination of amount of heat picked-up from items being thermostatted; improved thermal conditions of items.
