11月3日,我国研制的起飞规模最大、技术跨度最大、运载能力最大的新一代大型运载火箭——长征五号在海南文昌成功首飞。航天科技四院提供了此次发射中的正推火箭和消氢点火装置这“两样法宝”。正推火箭提升了芯二级推进剂的管理能力,确保了芯一级与芯二级发动机的成功分离;消氢点火装置消除了火箭发射前排放的大量低温氢气,安全护航火箭成功发射。
On November 3, the new generation of large launch vehicle developed by China with the largest takeoff scale, the largest technology span and the largest carrying capacity - the first flight of the Changzheng V No. 5 in Wenchang, Hainan Province. Space Science and Technology Fourth Hospital provided the launch of the push rocket and hydrogen elimination ignition device “two magic ”. The launch of the rocket enhanced the management capability of the core two-stage propellant and ensured the successful separation of the core-level and the core-two engines. The de-hydrogen ignition device eliminated a large amount of low-temperature hydrogen discharged before the rocket launch and the safety escort rocket was successfully launched.
