Deep Blue Aerospace: Key progress made in research and development of the core propulsion system for the recoverable launch vehicle "Nebula II".

Recently, the core power system of Deep Blue Aerospace's large reusable launch vehicle "Nebula II" has made another key progress in research and development. The "Thunder-RS", the domestic largest thrust liquid oxygen kerosene variable thrust engine, successfully completed two full-duration ignition tests of 5 seconds and 40 seconds. This engine can produce a thrust of up to 130 tons, making it the largest domestically produced pintle-type liquid oxygen kerosene engine. This successful milestone signifies that the engine has officially surpassed the steady-state working threshold and also indicates that the engineering validation of the "Nebula II" rocket's power system has entered a new stage of high density and fast pace.
