Re: General thoughts
Some thoughts upon reading your post.
I'm assuming the boffins in training who design the LOHAN airframe did some calculations on the stability under thrust and stability in flight. I have no doubt this airframe will fly in normal atmosphere. How it'll fly in the rare atmosphere at altitude is anyones guess.
A test flight of LOHAN is still on the to-do list at this point. In terms of load on the airframe I doubt a test in atmosphere of a firing in atmosphere is going to be very instructive as things like aerodynamic flutter and high lift loads start rearing their ugly head.
The stick idea is a possibility but how do you keep the rod on the plane during the ascent? This creates a whole new slew of problems to overcome.
