Conceptualized as the sucessor to the SR-71 Blackbird, the SR-91 Aurora was designed to break the very limits of what a jet is capable of. This plane features 4 powerful ramjets and 4 impressive high speed scramjets. This aircraft will efforlessly reach mach 4 once all engines have been activated at 20km, and reach mach 6 within the next half hour. If you have the time to spare and the patience, you can take this plane to a speed of mach 9.7 at an altitude of 58km!

    @SelectAKey The compression ratio makes a small difference, the bypass ratio makes a slightly bigger difference. But that makes the greatest difference is the size and mass. To put it simply, I made the engine bigger and then shrunk it in the tinker pannel so I could make small engines that have a lot of power.

    @lordvader0219 so its the bypass to compression ratio?

    @SelectAKey I set the jet size to 300, the bypass ratio to 0, and the compression to 30. Then I shrunk down the engines to 10% scale in the tinker panel, 0% mass, and 0% drag. Regular jet engines would not give the SR-91 the performance it has.
