Solid Rocket Motor Test Stand Project
The UCI Rocket Project's solids team needed a stable and durable yet easily transportable test stand to safely, rapidly, and reliably test their high-powered solid fuel rocket engines in various locations as necessary.
Goal: Design a test stand that could measure the thrust profiles of solid rocket motor prototypes
​
Method: Integration of a steel and Aluminum frame, motor mount carriage, and load cell data acquisition system capable of recording motor thrusts of up to 2,500 N
​
Result: Tests of load cell system work with small weights (20-80lbs) with reasonable accuracy but high powered rocket loads have yet to be tested

Conceptual Pencil Sketches
Preliminary Design
Preliminary CAD Design: Frame and motor mount assemblies designed by Ariya Lam Olaee and Christian Alvarez
Final Design
Finished SolidWorks assembly of the final test stand design: Frame and motor mount assemblies designed by Ariya Lam Olaee and Christian Alvarez
Requirement Verification
Static structural stress analysis on the frame shows a 0.03 mm max displacement under max 5000 N load
Frequency analysis shows mode shapes occur at resonant frequencies of 66 Hz, 133 Hz, 209 Hz, and 138 Hz (testing conditions must avoid)
Thermal stress analysis on the motor mount shows a 0.1 mm max displacement under 300°C load
