    software for modeling complex ballistic projectiles

    Does anyone have leads on software packages for modeling ballistic projectiles or "vehicles" (implying something more complex than a projectile, like a UAV for example)? In particular I am interested in: - porous drag components - chutes, ballutes, trailing strips, etc. - non-axisymmetric...

    Yaw frequency - where does it come from?

    If someone could explain what factors affect yaw frequency - why it can be 30 Hz in one finned projectile and 2 Hz in another not-so-different (perhaps fatter) projectile, etc - or just offer a basic discussion of the parameter, I'd be grateful. I'm a mechanical engineer by training, so use...

    How to Robustly Join Rubber Tread/Track?

    My company is developing a small (100 lb) tracked vehicle for all-terrain/rugged conditions. We are trying to adapt a sample of rugged snowmobile track for our purpose. As our vehicle is smaller than a snowmobile, we cannot buy the right size track - we must cut the track and join it at the...
