The engine underwent a dual-ignition test last Friday at a testing facility in Fengxian County, Shaanxi Province, which confirmed its performance and functionality, as stated by the Academy of Aerospace Propulsion Technology, a major producer of liquid-propellant engines in China, located in Xi'an.

This testing process included 30 ignitions across 15 tests, achieving over 3,900 seconds of burn time. This engine, a project of the China Aerospace Science and Technology Corp., employs liquid oxygen and kerosene and boasts a thrust capacity of 130 metric tons, featuring a variable thrust system.

The engine is designated for use in future reusable rocket designs currently under development at the corporation.

Gao Xinhui, a senior researcher at the Xi'an-based academy and the project lead, commented on the engine's advancements over existing models in terms of power and efficiency, and noted reductions in weight and size. Gao highlighted that the recent tests were also geared towards validating the engine's quick maintenance post-use to enhance reliability and determine its service limits.

Continued tests will assess the engine's reusability and performance consistency, Gao added.

As reusable rockets gain traction globally, spurred by successes like SpaceX's Falcon Heavy, China Aerospace Science and Technology Corp is also exploring this technology, with plans to introduce two rocket models with varying diameters in the next two years, as revealed by Wang Wei, a senior executive at the company last March.

Jiang Jie, a prominent scientist at the corporation, emphasized that a reusable space transport system would greatly enhance China's space access and development while reducing launch risks, lowering costs, and advancing space technology.
