Can handle up to 9 atmospheres; doesn’t seem like enough for the enviro of a jet engine.
Do remember that 9 atmospheres is 0.9 million newtons per square metre. 🙂
That’s like supporting a 90 tonne vehicle on top of a 1m² window.
Seen head-on, a vehicle of this type might be reminiscent of a manta ray. With a huge mouth, its cross-section is mostly engine, in comparison to its airfoil and payload.
