The invention provides an overall structure of an
assembly recovery rocket based on a general
core level. The overall structure comprises the following components of two first-stage
liquid oxygen kerosene engines, a first-stage empennage, a first-stage
tail section, a first-stage rear transition section, a first-stage
kerosene tank, a first-stage inter-tank section, a first-stage
liquid oxygen tank, a grid
rudder and a second-stage inter-tank section. Two second-stage
liquid oxygen kerosene engines, a second-stage kerosene tank, a second-stage tank interval section, a second-stage liquid
oxygen tank, an instrument disc, a supporting cabin, an adapter and a belting connection unlocking device; each universal core-level booster comprises a
nose cone, a grid
rudder, a reaction thrust
system, a liquid
oxygen tank, an inter-tank section, a
coal oil tank, a rear transition section, two liquid
oxygen kerosene engines, a
tail section and a landing buffer mechanism; front, middle and rear binding connection devices; a
satellite fairing; the reverse thrust
rocket is arranged between the first core stage and the booster box; and the forward thrust
rocket and the reverse thrust rocket are arranged in the second-stage
coal oil tank. According to the invention, general core-level
assembly recovery is realized for the first time in China, an efficient and reliable
assembly rocket
recovery scheme is provided, the safety of a rocket falling area can be improved, and the rocket launching cost is greatly reduced.
