China has recently achieved another milestone in rocket debris safety treatment - its first-ever parachute landing of the payload fairing, according to the China Academy of Launch Vehicle Technology (CALVT).
CALVT said the July 19 launch of a Long March-2C Y49 carrier rocket that successfully sent three Yaogan-30 Group 10 satellites included new parachute-based technology for a rocket nose cone controlled landing. The aim is to constrain the potential landing area by up to 80 percent in order to ensure the safety of the rocket remains' re-entry.
It was the first time China landed a fairing using a parachute, laying a solid foundation for future accurately controlled landings of rocket fairings, CALVT said.
According to mission insiders, such technology comprised two subsystems - the electrical system inside the payload nose cone to control the parachute and a parachute system.
The process is done under real-time monitoring. When the fairing falls to a certain altitude, the parachute will be activated to conduct a first-stage deceleration. As the nose cone continues to descend, it will drop the parachute and open the parafoil for the second-stage deceleration, during which the rocket section would fly to a fixed landing site under control, they explained.
Since three of China's four space launch centers are deep inland and its space launches have become increasingly frequent, it's becoming more urgent to master the precision recovery of rocket debris to ease the pressure of pre-emptive evacuations in potential landing areas, the CALT said.
The complete success of the flight test of the parachute system showed that China has made a major breakthrough in the high-altitude deceleration and landing technology of rocket fairing. It is also conducive for the development of reusable spacecraft and accurate delivery of emergency supplies.
The Long March-2C rocket series research team plans to continue testing the controlled fairing landing technology in launch missions next year.
據中國運載火箭技術研究院（CALVT）稱，中國最近在火箭碎片安全處理方面取得了另一個里程碑 - 其有效載荷整流罩的首次降落傘著陸。
CALVT 表示，7 月 19 日發射的長征二號 Y49 運載火箭成功發射了三顆遙感-30 10組衛星，其中包括用於火箭鼻錐控制著陸的基於降落傘的新技術。目的是將潛在的著陸區域限制多達80%，以確保火箭殘骸再入時的安全。
CALVT表示，這是中國首次使用降落傘使整流罩著陸，為未來火箭整流罩的精確控制著陸奠定了堅實的基礎。
據任務內部人士稱，這種技術包括兩個子系統——有效載荷鼻錐內控制降落傘的電氣系統和降落傘系統。
該過程是在實時監控下完成的。當整流罩下降到一定高度時，會啟動降落傘進行一級減速。他們解釋說，隨著鼻錐繼續下降，它將放下降落傘並打開翼傘進行第二級減速，在此期間火箭部分將在控制下飛往固定著陸點。
CALT表示，由於中國四個航天發射中心中的三個位於內陸深處，航天發射越來越頻繁，掌握火箭碎片的精確回收，以緩解潛在著陸區先發製人的疏散壓力變得更加緊迫。
降落傘系統飛行試驗的圓滿成功，表明我國在火箭整流罩高空減速著陸技術上取得重大突破。也有利於研製可重複使用的航天器和準確運送應急物資。
長征二號丙火箭系列研究團隊計劃明年繼續在發射任務中測試可控整流罩著陸技術。
