ROCKET BOOSTER Russian patent published in 2011 - IPC B64G1/22 

FIELD: transport.

SUBSTANCE: invention relates aerospace engineering, namely, to design of rocket boosters. Rocket booster comprises housing consisting of top adapter with metal environment, central adapter, bottom adapter, oxidiser and fuel tanks, intertank frame, sustainer and engines of stabilisation, orientation and launching that have low-thrust engine units. Top adapter accommodates instrumentation frame with its top bulkhead supporting spacecraft. Instrumentation frame accommodates containers with control system instrumentation, chemical current source, thermal control system, telemetry system and antenna-feeder devices. Thermal control system pipelines are connected to instrumentation containers to feed carrier to thermal control appliances for instrumentation. Thermal control system comprises plug-in joint arranged on bottom adapter to connect ground heat carrier feed devices and pipelines to withdraw heat from instrumentation in preparation of booster for launching. Pipelines are secured on fuel tank, intertank frame, top adapter and instrumentation frame. Radiant heat exchanger is made up of metal environment of top adapter whereto heat is fed vie thermal control pipelines rigidly attached thereto. Central adapter accommodates fittings to secure locks of nose cone separation from booster and brackets to secure nose cone flap turn assemblies after operation of separation locks. Low-thrust engines arranged on fuel tank lower bottom additionally comprise increased thrust overload nozzles to allow fuel components feed to tank intakes to launch booster sustainer at minimum stock of fuel in final stage of its operation.

EFFECT: improved weight-and-power characteristics of proposed booster.
