DEPLOYING DIVERGING PART OF ROCKET ENGINE (VERSIONS)

摘要

FIELD: rocketry. SUBSTANCE: diverging ring 22 which can displace between compressed position in which it encloses first part of diverging part 20 and deployed position in which it is connected to low end of first part in direction of flow. Deploying mechanism 30 makes diverging ring move from its compressed position to deployed position under action of actuator 44. temporary structure or "insert" is placed inside diverging ring 22 so as to transform its diverging section into non-diverging section at least in main part of length of diverging ring. Insert can be removed when diverging ring gets its deployed position or after deployment. EFFECT: provision of deploying diverging part requiring reduced energy consumption for deployment. 27 cl, 11 dwg
