Exodus Space AstroClipper

Stock airbreathing TSTO (Two Stage to Orbit) spaceplane configured for use in 1:1 solar systems. This launch vehicle is composed of two distinct parts, the supersonic boost stage and the orbiter. The purpose of the boost stage is to get the orbiter up to Mach 4, at which point it detaches from the boost stage and ascends to orbit. Propulsion system consists of 6 low-bypass afterburning turbojets and 2 kerolox rockets.

This vehicle requires a high amount of patience, it ascends to orbit on very tight margins. Small errors, such as forgetting to retract landing gear, too steep of an ascent, excessive control surface deflection, can result in a failure to reach orbit. If you are not highly intimate with airbreathing spaceplanes, do not expect to reach RSS LEO first try.

Ideal mission profile consists of a very shallow (5 - 10 m/s) ascent to 22-25 km. At this point, you have reached cruise. To reach Mach 4, level out and wait as the vehicle accelerates. It will take at least 10 mins. Patience is paramount, if a maximum speed is not found, then the orbiter will not make it to orbit. Once almost all the jet fuel is expended, turn off the jets with AG1 and power on the rockets with AG 2. When ready, detach from the boost stage with AG 3. Follow a steep ascent up to orbit (80 - 150 m/s). Margins will be extremely tight.

I will probably continue to detail this and release a version configured for 1:5 scale systems, featuring a VTOL orbiter.
