Tianbing science and technology Tianlong-2 liquid carrier rocket fairing separation test is a complete success

CTOnews.com, December 21, Tianbing Science and Technology announced yesterday that the fairing separation test of the Tianlong-2 liquid carrier rocket has been a complete success recently. In the process of separation, the timing is correct, and the kinematics measurement results are consistent with the simulation results. there is no damage to the product after the test, so it can directly participate in the first flight.

The fairing is an important barrier on the launch vehicle to provide good mechanical environment and thermal environment for payloads such as satellites. In the process of rocket flight, when the aerodynamic pressure and heat flow conditions are small enough, the fairing is separated from the arrow body, so as to reduce the structural weight of the arrow body and improve the carrying capacity.

CTOnews.com learned that Tianbing Science and Technology said that the separation process of the fairing is only about one second, but it involves a variety of physical processes, such as timing, overload, strength, stiffness, collision, impact, movement, and so on, so this test is also an important large-scale ground test in the stage of engineering development.

According to reports, this separation test was carried out on the site and separation and recovery equipment built by Tianbing Science and Technology, and the cover body was recovered with lightweight civil materials, which greatly reduced the test cost. The success of the test verifies the correctness of the fairing separation scheme and the reliability of the product, which lays a solid foundation for the successful first flight of Tianlong II.
