The payload fairing separation test of the ZQ-2 carrier rocket saw complete success
Recently, LandSpace accomplished the payload fairing separation test of its ZQ-2 carrier rocket (ZQ-2) and verified the performance of the fairing, and the timing, and the whole process of separation. With all data complying with design requirements, the test demonstrates the excellence of separation design and interface compatibility, and laid a solid foundation for the maiden flight of ZQ-2.
Located at the front end of a carrier rocket, the fairing helps to control the gas flow and protects the payload from the detrimental effect of aerodynamic forces, aerothermodynamic, and acoustic and vibration loads when the rocket is traveling at a high speed in the atmosphere. During the atmospheric flight, the fairing for a large liquid rocket shall be solidly joined with the rocket body, withstand high-speed impingement by fast gas flow, and provide the payload with a favorable internal environment. Once the rocket travels beyond the aerosphere, the fairing shall be timely separated.
Solid joint and easy separation, seemingly a contradiction, are expected to be attained on the fairing. The fairing for ZQ-2 is separated and jettisoned like a bifurcating shell. The fairing, with a diameter of 3.35 meters and a total length of 8.24 meters, resembles a clamshell and comprises a non-metal end cap, and the cone-cylinder combination of a skin-stringer structure. As the largest one in the private aerospace sector in China, the fairing fills the gap.
About Zhuque-2 (ZQ-2)
ZQ-2 is the largest LOX+LCH4 carrier rocket in development in China and also the first medium-sized commercial carrier rocket with the propellant of LOX+LCH4 in China. The 49.5-meter rocket has a diameter of 3.35 meters. With a lift-off thrust of 268 ton at 216 ton in mass, it can deliver 6-ton payloads into LEO or payloads to the orbits of other heights through the combination of rockets in parallel.
