A space-plane needs to have a wing sweep angle of > 70 degrees to shed the shock waves of high mac flight in the atmoshere or re entry.
Why there wasn't any sweep in X-15 nor F-104 ?
I mean idea is to brake in the thin air..not to brake it.
The whole point is flying much higher than any of the previous planes have reached with 1/30 wingloading. Check what altitude the meteorites start to burn up and at what speed. Then you get the glue.
Thank you so much for posting. I have been looking for something like this.solar energy
No problem....I wonder why the industry hasn't done a proposition yet ?
