Advanced Launcher Applications

Horizontal launch of TSTO and SSTO vehicles

Based on the model library with this ASTOS application you easily determine

optimal 3-DOF trajectories of single-stage or two-stage-to-orbit launch systems with horizontal take-off,
optimal throttle settings for six different controllable engine models: rocket engines with fixed or variable mixture ratio and several air-breathing jet engines,
optimal tank budgets for fuel and oxidizer
maximizing f.i. payload, final mass or minimizing fuel consumption.

The application also provides an automatic start-up based on the mission specifications. A dynamic pressure guidance and several upper stage guidances are used to determine an initial trajectory and control functions. This trajectory serves as an initial guess for the optimization.
