In Fall 2024, I designed the mechanical structure of an adjustable horizontal engine thrust test stand capable of testing motors ranging from 29 mm to 80 mm in diameter. I performed hand calculations to evaluate the structural integrity and ensure the frame could safely withstand the expected thrust loads.
The test stand’s main structure was constructed using 80/20 aluminum bars, to allow for simplicity in assembly and modularity of the design. I precisely measured and cut the aluminum bars using a cold saw. The design also incorporates sliding rails and custom-milled mounting plates, enabling the supports to accommodate different sized motors.
The teststand integrates a 3,000 psi pressure transducer to measure the chamber pressure during static fires. To ensure reliability, I designed and performed a pneumatic pressure leak decay test on the pressure transducer prior to the static fire.
We conducted a static fire test using a COTS engine to validate the test stand’s functionality and stability. During the test, I configured the data acquisition devices and mounted the motor. The static fire was successful, and the test stand will be used for future motor testing.
