The entry into the atmosphere is flown at a high AoA of 40 degrees, creating a detached shockwave of hot plasma which limits the direct heat transfer to the fuselage, while at lower Mach numbers the AoA is gradually reduced, leading to a more aircraft-like behavior. Through this range, the aerodynamical properties change drastically. Spanning the full range of a rarified atmosphere rushing by at Mach 27 to the dense low atmosphere through which the Shuttle glides at subsonic speeds on final approach, the orbiter probes a huge variety of conditions. Download repositories: Last stable version Possibly unstable development version Aerodynamics The main platform for the aerodynamical, orbital motion and systems simulation is JSBSim, a sophisticated Open Source multi-platform flight dynamics engine which is also used in research and professional applications.įor the 3.6 release, the Shuttle is a beta version - the modeling of aerodynamics, flight controls and systems is in a fairly advanced state, but the visuals (both outside and in-cockpit) and the avionics displays are work in progress. The Space Shuttle model for Flightgear, released together with version 3.6, aims to re-create this experience by a detailed modeling of all aspects of the spacecraft's operations, ranging from sophisticated aerodynamical modeling to a comprehensive simulation of the Shuttle's systems and the effect of their failures.
