The parachute landing system reduces the landing area by up to 80%, the China Academy of Launch Vehicle Technology (CALT) announced on June 9. The test occurred on May 17 when the Long March 3B rocket successfully launched, carrying the 56th satellite for China’s Beidou navigation system.
After analyzing the test data and debris at the site, CALT found that the parachute system followed a predetermined landing trajectory, accurately guiding the rocket’s separated components to the designated landing area. CALT stated that this new test lays the groundwork for the large-scale application of the parachute system in future projects.
The parachute system, developed independently by CALT, aims to enhance safety in the landing zones of rocket components. Most of China’s major launch sites are located deep inland, making it crucial for scientists to prevent rocket parts from falling randomly, especially in populated areas.
During the test, the high-tech parachute system was deployed on one of the four booster components of the rocket and was activated after the booster separated from the rocket and fell from a certain altitude. The parachute system helps control the altitude and direction of the rocket component, guiding it to the designated landing site.
Experts can precisely control the system after multiple optimization steps. According to CALT, they have optimized the parachute system with auxiliary electrical systems, reducing the weight by 30 kg and making the parachute system more practical.
