METHOD OF THERMOSTATTING OF ROCKET POD ITEMS AND ONBOARD SYSTEM FOR REALIZATION OF THIS METHOD

摘要

FIELD: methods and devices for thermostatting instrument compartments, control system automation units and other items of rocket pod. ^ SUBSTANCE: thermostatting medium is injected into rocket pod on side of its lateral surface at angle to cross-sectional plane of rocket pod at shift relative to rocket pod axis due to which thermostatting medium is twisted relative to rocket pod axis of symmetry. Proposed system has holes for injection and escape of thermostatting medium with single-acting valves and thermostatic medium injection unit. Holes for injection and escape of thermostatting medium are made in rocket pod envelope. Single-acting valves of said holes are articulated in rocket pod envelope. Thermostatting medium injection unit is made in form of subsonic diffuser with bent axis and is mounted in gap between rocket pod items and its envelope. Inlet hole of diffuser is communicated with injection hole of rocket pod envelope. Outlet hole of diffuser is so located that tangent to diffuser axis in its exit section is directed at angle to plane of rocket pod cross section and at shift relative to rocket pod axis of symmetry. ^ EFFECT: enhanced heat exchange on surfaces of rocket pod items during prelaunch preparation; reduced mass of onboard thermostatting system. ^ 3 cl, 4 dwg
