The Changer Bingyao 49 rocket in China took off at the Xichang Satellite Launch Center and successfully sent 3 satellites of the remote sensing 30 group into the predetermined orbit. The launch mission was a complete success.
A few days ago, according to the official public account of the “China Academy of Launch Vehicle Technology”, different from previous missions, this launch mission was also equipped with “parachute-based fairing landing zone control technology”, which broke through the fairing and re-enter the atmosphere.
The structural disintegration problem is the first realization of the parachute landing of china launch vehicle fairing.At the same time, it lays a solid foundation for the subsequent precise control of the fairing landing zone.
So what is “parachute-based fairing landing zone control technology”?
According to reports, this technology is to install a parachute control electrical system and a parachute system in the fairing to monitor the re-entry flight state in real time. When the fairing drops to a certain height and meets the parachute attitude conditions, the deceleration parachute is opened for the first stage.
After decelerating and descending to a certain height, abandon thedeceleration parachute and open the parafoil. While performing the second-stage deceleration, the fairing homing control is carried out, and the fixed point landing is in a safe area.
This technology can reduce the original landing area of the fairing by more than 80%, greatly improving the safety of the landing area, and greatly reducing the evacuation pressure of the landing area.
It is worth mentioning that this launch is also a phased final battle of the remote sensing 30 series satellites, which is equipped with a micro-nano satellite of the Apocalypse Constellation 15 for data collection of the Internet of Things.
