Recently, Galactic Energy successfully completed the wind tunnel test for aerodynamic characteristics of the reverse jet of the first stage of the reusable launch vehicle, "Pallas 1". This test primarily targeted the prediction of aerodynamic characteristics of reverse jet, which is one of the core key technologies for rocket recovery.
During the high-speed re-entry and return of the first stage of the rocket at orbital speeds, the rocket is in a special "head-over-tail" flight state. At this time, the interaction between the engine jet and the incoming flow generates complex aerodynamic interference effects, increasing the difficulty of predicting the aerodynamic characteristics of the entire rocket and control surfaces. The accuracy and reliability of aerodynamic data are of great significance for improving the efficiency of rocket recovery and reuse, the precision of landing, and the safety of the recovery process. Therefore, the aerodynamic prediction technology for reverse jet during sub-stage recovery is one of the key technologies for achieving rocket recovery.
With the support of the Beijing Municipal Science and Technology Commission and the Zhongguancun Management Committee, Galactic Energy, relying on the joint fund of the Beijing Natural Science Foundation and the Economic-Technological Development Area, jointly conducted a series of key technology research and development on aerodynamic and thermal design and prediction methods for rocket recovery with leading scientific research institutions in the industry, such as the China Aerospace Aerodynamics Research Institute, and achieved important research results.
The successful completion of this reverse jet wind tunnel test has provided critical data support for the subsequent design of the recovery guidance and control system. Galactic Energy has continued to make solid progress in the research and development of the recovery project for medium and large reusable launch vehicles in the Pallas series. In the future, Galactic Energy will continue to devote itself to the research and innovation of rocket recovery technology, contributing to the rapid development of China's commercial aerospace industry.
