Hypersonic
Hypersonic refers to speeds that are significantly higher than the speed of sound. In the context of space and astronautical engineering, hypersonic usually refers to speeds above Mach 5, or five times the speed of sound. Hypersonic vehicles are designed to travel at these high speeds, which can enable faster travel times and more efficient space exploration. However, hypersonic flight presents significant engineering challenges, including high temperatures and pressures that can cause materials to degrade or fail. Hypersonic vehicles may use advanced materials and cooling systems to manage these challenges. Hypersonic technology has potential applications in both military and civilian contexts, including missile defense, space exploration, and commercial transportation.
