Abstract
Project Anubis’ main objective is to design, fabricate, and test a cold gas thruster attitude control system with at least 2 degrees of freedom. This project will serve as a test-bed to develop an active attitude control system for the Mountain Spirit Program, which is a program to develop a space-shot rocket at Embry-Riddle. The system will use an inertial measurement unit (IMU) to determine the attitude of the system in the yaw, pitch, and roll axes with respect to its vertical attitude. The IMU will send data to be processed in a Raspberry Pi, which will control specific solenoids to allow pressurized gas to go to the thrusters. This will allow the system rotate back to its initial attitude. The software on the Raspberry Pi will use dead band control, so that within a specific range away from the vertical axis, the thrusters won’t fire. This ensures that the vehicle only needs to correct its attitude when its attitude is too far away from being vertical. The hardware of the system is intended to be cost-effective such that it can be used for future flight vehicles such as rockets for the later stages of Mountain Spirit. The majority of the hardware was sourced from a similar, but previously dismantled system with solenoids, Composite Overwrap Pressure Vessel, and thrusters. This lowered the budget as those parts, once working, wouldn’t need to be bought or fabricated. Initial testing has shown that with 100 psi, the system has enough thrust to rotate, while subsequent testing has gotten the IMU data to correctly fire the correct solenoids. The next stage will be to connect the entire pressure system together, and then test the system on a dedicated test stand.
