My mentions: mansplaining the F-35, which is a program I worked on.

I studied free-play nonlinearity induced limit cycle oscillations of the horizontal stabilizer using transonic tests of the tail empennage.

hey wanna do basically the same thing but for unusually wide control surfaces on the first stage of a launch vehicle

The challenge is only in the transonic regime. You're just gonna use power to get past that.

this is true but the vehicle is going to have a very limited inclination range unless it maneuvers early

i expect the combination of srb acceleration and relatively severe vectoring is going to require some clever wing design

the big challenge is fighting the internal stresses if you're using aero maneuvering. Basically fighting against the engine.

i'm fairly confident the vehicle itself can withstand the stress, a scramjet does not have many points of shearing failure

the stage linkage is a little more concerning tho

The weird stuff comes when you get things e.g. skin stress on the fuse, etc. A lot depends on materials. Composites can come apart.

Aeroelasticity is all about failures being in the least intuitive spots.
