    MATLAB Writing a matlab program to solve the Kepler Problem (Universal Vars)

    Introduction: I am writing a Matlab program that solves the Kepler problem for any Elliptical, Hyperbolic, or Circular orbit. Given an initial position vector, velocity vector, find the position vector and velocity vector after some given time. I am not doing this for any class, I have been...

    Optimizing Thrust and Operation Time for a CO2-Powered Rocket Torpedo Design

    I don't see how you can say that in absolute terms. My graph of velocity Vs time shows it would take the torpedo less than .5 seconds to accellerate to speed under .25N of thrust. If Po/Pe = 2 and the vessel was overpressurized to say 500psi surely the thrust would be constant for some time.

    Optimizing Thrust and Operation Time for a CO2-Powered Rocket Torpedo Design

    1. A CO2 canister with the following dimensions will be used. 2. A shell was designed to house the CO2 canister, and the coefficient of drag was calculated to be 0.33 3. The constant thrust required to move the torpedo at approximately 1ft/s was found by using a free body diagram to generate...
