yes, but those are ramjets, not SCramjets

I looked at your craft and here's the problems I found so far: 1. You need more wings to generate lift 2. The landing gear config is wrong. The rear landing gear should always be just a little behind CoM. Current state it will never take off 3. You need more pitching authority. In FAR, the CoL of wings shift to the rear like real world during supersonic flight, so trimming is always the (most difficult) problem for SSTO spaceplanes. 4. You need much more vertical stabilizers 5. You need one group of control surfaces assigned to Roll Anyway, I find the example crafts coming with FAR pack very instructive. FAR Kaiju and Fireball should be SSTO-able.

Since everyone's doing this I'm sharing my SSTO cargo spaceplane too. This is built and tested with B9, Taverius pack, FAR, deadly reentry and MJ2.0 Sending 27tons of payload into low orbit

If you can elucidate your problem everyone's happy to help. Did you try the ferram's example rocketes in the pack?

I assume this is a spaceplane that's capable of SSTO, but where are the wings? The idea of preventing overheat during re-entry is that, you keep a 30-40 degrees or as high as possible AoA, and use the extra drag to slow down, just like the real world space shuttle. I think we need to start a new thread in the spacecraft exchange sub-forum to discuss these. I'll be posting my cargoship later there

You bet wrong. One can just use RCS, a lot of them. I play with FAR and deadly re-entry. I keep my shuttle nose-up 30 degrees at high atmosphere, like what the space shuttle does

@ferram4: I have a question for you. In FAR model you used Prandtl lift-line theory to calculate lift and induced drag. But is it correct for low aspect-ratio, large swept wings which are common for supersonic flight?

I would keep a 30 degree AoA while re-entry, and use lots of RCS to keep that flight attitude and avoid tail spin. Typically I start with a 80 x 0 km orbit and turn on RCS at 40km. Then at ~20km the speed should be < 3 Mach and I just point the nose to prograde and turn off RCS This method is less reliable but much quicker. The wings are stalled so there's no lift

From my experience you need bigger vertical stabilizers.
