Rocket Engine – A Rocket Engine Propulsion Package In The Tool Command Language (Tcl)

Abstract

DLR’s Space Liner orbiter concept flight simulator bases on a thrustless flight dynamics model for associated descent/approach trajectory analyses. Investigations of the rocket-propelled ascent phase demand the implementation of simulated thrust. For that purpose, a Tcl rocket engine propulsion package has been developed. Its configurable parametrization including the transient regime is described. Package usage test results in a standalone application show a thrust update interval below 4 milliseconds (median). Future options of different human-in-the-loop real-time system of systems integration capabilities are presented and discussed.
