In 420 seconds, the first long-range test run of a deep blue aerospace liquid oxygen kerosene rocket engine was a complete success.

CTOnews.com October 23 news, Jiangsu Deep Blue Aerospace Co., Ltd. announced, Recently, Deep Blue Aerospace independently developed reusable liquid engine "Thunder-R1," The first rated condition 420 seconds long-range test.

The test run time covers more than twice the flight time of the recoverable reusable rocket "Xingyun-1" sub-stage. The engine starts and shuts down normally. The whole process works stably. The test is successful, marking that the "Thunder-R1" engine enters the stage of series boundary, life and reliability test run.

Deep Blue Aerospace said that as the first pintle reusable liquid oxygen kerosene engine in China, this long-range test verified the working reliability and stability of the system and components of the "Thunder-R1" engine under rated conditions, and proved that the "Thunder-R1" distance was officially delivered to carry out the high-altitude recovery test of the first sub-stage of the "Nebula-1" rocket, as well as further flight into orbit.

CTOnews.com query learned that "Thunder-R1" is a liquid engine product specially developed for vertical recovery and reusable launch vehicles. The engine is 85% weight manufactured by 3D printing and uses pump swing for the first and second stages of Deep Blue Aerospace "Nebula-1" recoverable multiplexed liquid launch vehicle.

Up to now, the accumulated test run time of the same engine has reached 2000 seconds, which verifies the fatigue resistance and service life of engine components under harsh engine working environment.

Long range test run is an essential link of Type I engine from R & D, production to engineering application. The success of this long-range test provides strong power support for the subsequent "Nebula-1" rocket orbit.
