FIELD: power engineering.
SUBSTANCE: device comprises boxy aprons (7) fixed by their one side to separate part of split joints (6) of rocket speed-up unit (3) in process of pre-start preparation. Sealant (8) with slots is fixed to opposite side of each apron (7). Part of sealant with slots rests on mount (10) of speed-up unit (3) hatch (5). Slots provide for sealant adjacency to hatch mount along its perimeter. Flow of thermostatting air is used to press sealant (8) to mount (10) of hatch and to prevent excessive exhaust of air through hatch.
EFFECT: stabilisation of temperature mode in process of pre-start preparation in cavities of space head part and rocket speed-up unit with hatches open in rocket speed-up unit after connection of mechanisms for withdrawal of split joints.
