Short Introduction to Flight Trajectories for Aerothermodynamicists, or hypersonic aircraft depend mutually on each other. We give here a short introduction to issues of flight trajectories in order to provide basic knowledge about these dependencies..The very fast flight of hypersonic vehicles, partly with vast changes of the flight altitude, makes a precise flight

Aerothermodynamic Design Problems of Winged Airbreathing Vehicles,rizontally. As we have learned from Chapter 3, the Space Shuttle Orbiter is launched vertically like a rocket with the support of solid rocket boosters. The re-entry process into the Earth’s atmosphere consists of a gliding unpowered flight and a horizontal landing on a conventional runway. Moreover

Aerothermodynamic Design Problems of Non-Winged Re-Entry Vehicles,ment and construction of suitable vehicles which are able to withstand the very severe thermal and mechanical (pressure and shear stress) loads encountered during such a mission. In the early days of space exploration, the designers had the feeling that the vehicle shapes should be as simple and com

Short Introduction to Flight Trajectories for Aerothermodynamicists, problem is to find a flight trajectory which permits the vehicle to fulfill its mission with minimum demands on the vehicle system. However, different from classical aircraft design, the physical properties and the functions of a hypersonic vehicle and its components must be extremely closely tailored to the flight trajectory and vice versa.
