Zhongke Aerospace's Lijian-2 Liquid Launch Vehicle Test Achieves Success
TapTechNews August 13th news, the official of Zhongke Aerospace announced that the long-duration joint test of the 85-ton liquid oxygen kerosene engine of the first stage of the Lijian-2 liquid launch vehicle and the servo system has achieved a complete success.
According to the introduction, the test duration is 320 seconds, and the cumulative test duration of a single engine has reached 720 seconds, meeting the requirement of not less than 4 times the flight working duration. This test not only explores the working life of the engine but also assesses the reliability of the servo's long-term power-on operation.
The official pointed out that the complete success of this test marks that the first-stage engine of the Lijian-2 liquid launch vehicle and the servo system have passed the reliability verification, and after the engine and servo system are delivered in the future, the test of the power system will be carried out.
TapTechNews learned from the official data that the Lijian-2 is positioned as a medium-sized liquid launch vehicle. It is a large-thrust, high-reliability, and low-cost liquid launch vehicle created for the future large-scale constellation networking construction and responding to the demand for low-cost cargo transportation in China. It adopts the CBC configuration, with a common core stage diameter of 3.35 meters, a total length of 53 meters, a takeoff weight of 625 tons, and a takeoff thrust of 766 tons.
The Lijian-2 has a launch capacity of 8 tons in the SSO orbit and 12 tons in the LEO orbit, and has the launch capability in the sun-synchronous orbit, low-earth orbit, and transfer orbit, which will further enhance China's ability to access space on a large scale at a low cost and promote China's commercial aerospace to rapidly enter the 3.0 era.
At present, the Lijian-2 liquid launch vehicle has entered the large-scale ground test and verification stage of the engineering development and is planned to make its first flight in 2025.
