Propulsion system failureshrust by expanding and accelerating in a nozzle. High performance requires that the combustion occur at high pressure, which in turn requires that the propellants are either pumped in or forced in by yet higher pressure in the propellant tanks. In most cases, launch vehicles pump their propellants.Inflamed 发表于 2025-3-30 12:48:26

Environmental failurest from the Sun, and by nuclear radiation. Further, as a result of the large relative velocities involved in orbital and interplanetary flight, even specks of dust in space can have the kinetic energy of a rifle bullet. While our understanding of this environment has improved over the years, it contiotic-capsule 发表于 2025-3-31 03:41:19
Structural failurescessary in microgravity, it is required to hold the subsystems together on the ground, and during launch. In addition to the rigid structure, some elements are designed to move — either because they are too bulky to fit inside the launch vehicle’s aerodynamic shroud, or are too flimsy to support the
