The Tianlong-2 Yaoyi liquid carrier rocket made its first flight successfully, sending the Love Space Science satellite into its scheduled orbit.
CTOnews.com, April 2, 2023, 16:48 on April 2, 2023, the Tianlong-2 Yaoyi carrier rocket successfully made its maiden flight at China's Jiuquan Satellite launch Center, successfully putting the love space science satellite into the scheduled orbit, and the launch mission was a complete success.
The main purpose of this first flight test is to verify the correctness of the overall scheme of the launch vehicle and the coordination among the systems, and to obtain the flight environment parameters of the whole rocket. The Love Space Science satellite is mainly used to carry out remote sensing imaging experiments and other technical verification. It is reported that this mission is the first flight of the Tianlong II carrier rocket.
CTOnews.com inquiry learned that Tianlong II, from Tianbing Technology, is the first successful start-up in the world to launch a liquid carrier rocket! In addition, the successful maiden flight of Tianlong II also set a number of records:
The world's first launch vehicle that uses coal-based space kerosene to fly
China's first liquid launch vehicle that does not rely on launch stations
China's first launch vehicle with three parallel engines
China's first launch vehicle with full aluminum alloy surface tension tank attitude and orbit control system
China's first launch vehicle to realize the reuse of the arrow structure.
According to public information, the Tianlong II carrier rocket (TL-2) is a liquid oxygen / kerosene three-stage rocket with a diameter of 3.35m, a total length of 35m, a take-off mass of 150t and a take-off thrust of 190t.
The three engines in the core of Tianlong-2 liquid carrier rocket adopt the 85-ton open cycle liquid oxygen kerosene engine YF-102 developed by the sixth Institute of Aerospace Science and Technology. The specific impulse of the engine is 2700m / s, the thrust-weight ratio is not less than 130. it adopts the swinging configuration in front of the pump. This first flight mission is also the first launch mission of an 85-ton open cycle liquid oxygen kerosene engine YF-102!
