Keesje,
Good work !
Still two remarks :
1/- Have you thought of the *gull wing* solution for a low wing project ?
Seems to work on a 380... and will improve the design (aerodynamics ) wing-to-fuselage connection ( perpendicular attachment )while shortening the landing gear legs.
2/- I notice that your props turn the same way...with 11,000 hp behind them, you have a massive torque effect while manoeuvering (right turn on a pitch-up, left on a pitch-down)...That will lead to piloting difficulties -and certification requirements on a *critical engine* (pitch-down moment on a right engine failure) or a serious study of autopilot controlled engine failure.
IMHO, you'll have two solutions :
2-a/- Contra-rotating props (that will also improve your trans-sonic aerodynamics on the prop tips)
2-b/- opposite rotation directions on the props...which means an increased investment on spare parts...not my favourite idea.
Your choice.
Regards
