WIP Rocket fighter

9,445 vcharng  5.3 years ago


This is my next build, you probably can find out what it is.
I can say that it's a rocket fighter with liquid-fueled rocket engine and accurate solid-fuel rocket boosters.

As I have posted yesterday, this plane has a serious issue of suddenly jerking. I'm not even sure if it's in the roll direction or yaw direction anymore.

It seems that it is the carriage (which would be ejected after takeoff) that causes this problem. Strangely, the problem persists even if I remove the carriage, but if I use another AG to manually jettison it into water, it is solved.

I'm gonna try to fix it, but if I can't, I'll have to tell my users to jettison the thing into the ocean....

    @vcharng high wing loading mean better maneuverability at high speeds, low wing loading means the opposite ,So choose what you want, and keep the main wing's airfoil to semi-Symmetric.

    @Mmdben Well my earlier work Me 262 Z HGIII have 92.7 lb/ ft2.... Perhaps that's why it turns like a brick... (<7 seconds in supersonic speeds, >10 seconds at WWII propeller speeds)

    @vcharng Pretty WHAT WHAAAAT my planes have a 18.5lb/ft2 and that's the max value. , That sh*t is high for a small plane like that. if you want to maneuver at low speeds that wing loading should be reduced.

    @Mmdben Hmm, wing loading? That's interesting. I'll definitely take a look.

    Edit: but you know what? the wing loading is actually pretty low.. (57lb/ft2)
    I'll take a look at control surfaces.

    " this plane has a serious issue of suddenly jerking" , try lowering the wing loading by making the wings bigger or making the plane lighter, make sure you don't have a huge control surfaces too ,make sure that the placement of COM and COL is good.
