China tests rocket parachute landing system

The parachute landing system was successful in the launch of the Truong Chinh-3B rocket in May, helping the landing process to be more precise.

The parachute rocket landing system reduces the landing area by up to 80 percent, the China Academy of Launch Vehicle Technology (CALT) announced on June 9. The test took place 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 pre-arranged landing trajectory and accurately delivered the rocket's ejected portion to the landing zone. CALT said the new test laid the foundation for large-scale application of the parachute system in future projects.

The parachute system independently developed by CALT is aimed at increasing the safety of the landing area of ​​rocket components. Most of China's large launch sites are located deep inland, so preventing rocket components from falling haphazardly, especially in areas with human activities, is an important task for scientists .

In the test, a high-tech parachute system was placed on one of the rocket's four boosters and activated after the booster separated from the rocket and fell to a certain height. The parachute system helps control the rocket's altitude and direction, bringing it to a designated landing site.

Experts were able to precisely control the system after several optimization steps. According to CALT, they optimized the parachute system with an auxiliary electrical system, which reduced the weight by 30 kg and made the parachute system more practical.
