China successfully tests technology that controls rocket fairing landings

(22 Jul 2021) China has successfully tested technology that can control the landing sites of falling rocket fairings, according to the China Academy of Launch Vehicle Technology (CALT).

CALT said the test was carried out following a Chang Zheng-2C rocket launch on 19 July.

The test solved the problem of the structural disintegration of fairings during reentry. It was the first time China landed a fairing using a parachute, laying a solid foundation for future accurately controlled landings of rocket fairings, CALT said.

The technology tested in the fairing was a parachute-control electrical and parachute system to monitor the status of the reentry flight in real-time.

With the new technology, when a fairing falls to a certain height and meets the conditions suitable for parachute deployment, the parachute opens to decelerate the fairing.

At a certain height of descent, a fairing will discard its drag chute, open its parafoil, and initiate deceleration a second time. During its slowdown, it will land in a safe area in a controlled manner.

CALT said the technology was able to reduce the fairing's original projected landing area by more than 80%, which significantly improved safety and reduced evacuation pressure in the area.

The Chang Zheng-2C rocket series research team plans to continue testing the controlled fairing landing technology in launch missions next year.
