    Using Side Thrusters on a missile to create an angular acceleration

    Assume a rocket is standing on the ground with mass = 1000 kg, and near the top of rocket we apply a force of 100 N for say 1 sec,now assume that this is sufficient to tip rocket over/start tipping over. If the rocket is mid air and accelerating at 30m/s^2, then likewise how much force would be...

    Measuring stress on drag device

    Hi All, I’m planning my L3. I have a 4” fiberglass MadCow DX3 XL, and planning on using an M1350 motor. However, this combo busts the altitude waiver, bottom line is that I need a planned apogee at about 11,000 AGL. Thought first about adding weight, but need close to 4 KG extra which creates...

    Sounding rocket aerodynamics and hypersonic flights

    Hi, everyone! I'm currently searching for any helpful literature on aerodynamics to design the airframe of the sounding rocket so that it suits for varying flight conditions (passing through subsonic; hypersonic speeds). Any recommendations on maybe existing papers and researches?

    Tips and Guidelines for Aerodynamic Stability?

    I've been designing a simple one stage rocket with OpenRocket, which allows the user to design and simulate their designs. I was always told that a general rule of thumb for a rockets stability is that the center of gravity should be 1-2 calibers above the center of pressure. With this rule...
