3DOF-Rocket-Simulation

Using MATLAB to simulate a rocket launch with constant acceleration (3DOF).

My brother had this project in one of his Aerospace classes, and I thought it sounded like a fun project. I got the physics formulas via text documents the teacher put out with the assignment.

Objective

Send a rocket from an initial altitude of 210m across a full parabolic flight path and end at 220m.

This is accomplished by using MATLAB's ode45 function to integrate the calculated Velocity and Acceleration vector over each time step.

Initial Values

• Position: 210
• Velocity: .001
• Time: 0s
• dTime: 0.1s
• rocketLength: 2.87m
• rocketDiameter: 0.122m
• wetMass: 65.6
• dryMass: 45.2
• thrustDuration: 1.8s
• thrustMagnitude: 21525
• initialTemperature: 300 (kelvin)
• initialPressure: 99000
• specificGasConstant: 287.058
• gravity: 9.8067
• lapseRate = -0.0065
