METHOD FOR THERMAL CONDITIONING OF SPACEHEAD BY HIGH PRESSURE AIR AND SYSTEM FOR ITS IMPLEMENTING Russian patent published in 2008 - IPC B64G1/50 B64G5/00 F25B29/00 

FIELD: transportation.

SUBSTANCE: suggested thermal conditioning system contains compressed air feed line (1), controlled device (pneumatic shield) (3) and reducing device (pressure reduction unit) (4). Pneumatic shield includes two parallel lines (7) with electropneumatic valve (8) installed in each of it, pressure indicator (9) and one-way valve (10). Pressure reduction unit also includes two parallel lines (16) with electropneumatic valve (17) installed in each of it, gas-pressure reducer (19), pressure indicator (21), safety relief valve (22) and one-way valve (23). Safety relief valve (22) is linked with drain pipeline (24) which is equipped with pressure indicator (25) electrically connected with each electropneumatic valve and one-way valve (26). According to suggested method, compressed air pressure of 40 MPa is reduced to 6-10 MPa after filling the carrier booster with fuel components. When safety relief valve of one of the lines of pressure reducing unit is actuated and/or when failure is detected in one of the feeding lines of controlled device, compressed air supply over given line is shut off and supply over parallel line of specified unit and/or device is opened.

EFFECT: increase of reliability in the launch preparation phase and during launch of carrier boosters with spacehead.
