We utilized various machining methods to construct our thrust mount. In order to cut out all the mounting plates and connecting brackets (Image 5), we learned how to use a waterjet cutter (Image 6) as it seemed like the most efficient way to complete our task. We sandwiched the load cells (Image 10) between the mounting plates we waterjet cut (Image 4) to attach to our thrust mount (Image 3). Since we needed to cut our 80/20 accurately both straight across and at a 45 degree angle (Image 7), we decided to use a horizontal band saw. Additionally, our final CAD design (Image 8) was created in SolidWorks. We used Finite Element Analysis (Image 9) to determine the proper dimensions and materials for our mount.

During the Spring 2024 semester, we constructed and machined the portable thrust mount we designed with load cells (Image 2) that supported static fire operations of 500 lbf liquid rocket engine. We successfully used the stand in our April 2024 static fire test (Image 1).

Thrust Mount For 500 lb Rocket
As the Structures Team Lead for the Harvard Undergraduate Rocket Propulsion Group, I guide my subteam of 4 in creating the rocket body, airframe, aerodynamic hardware, test stands, launch platforms/towers, etc. This semester, we are designing Harvard’s first airframe and rocket body for another static fire test.
