MODE OF TEMPERATURE CONTROL OF THE OBJECTS OF A ROCKET BLOCK Russian patent published in 2007 - IPC B64G1/52 B64G5/00 

FIELD: the invention refers to temperature control of the objects of rocket-space technique and may be used in the period of prelaunch preparation of a rocket block in the process of checking up of aerospace apparatus of its instrumental compartment.

SUBSTANCE: the proposed mode includes initial blowing of the temperature controlled medium into the rocket block at cutoff sources of heat generation of the temperature-controlled object At that they measure the temperature of the surface of the given object and temperature of gas medium in it in the period before reaching out steady-state meanings of the indicated temperatures. In accordance with the steady-state surface temperature the effective temperature of gas medium is determined. Then temperature-controlled medium with temperature not equal with effective is repeatedly blown into the rocket block, repeating above indicated operations. In accordance with the meanings of surface temperature of the object taking into consideration its mass and thermal capacity the parameter of heat transfer from the medium to the object is determined, and also dependence of quantity of heat taking off from the surface of the object from the temperature of its surface is set. This quantity of heat is compared with inner heat generation. At meanings of this quantity of heat larger or equal to the quantity of the heat allocated by the object and the surface temperature, less or equal to admissible the corresponding exploiting parameters of blowing medium at the input into the rocket block are fixed at the input into the rocket block.

EFFECT: increases accuracy of determination of quantity of heat taking off from the temperature-controlled object and owing to it and exploiting parameters of blowing of temperature-controlled medium providing optimal heat regimes of the objects.
