Test Stand Construction 7/15-7/19

This past week the Lunar Lion team was hard at work at the university’s machine shop putting the finishing touches on their vertical rocket test stand. The structural frame of the test stand was already machined and welded together with holes drilled for component attachment. We also cut the rocket mounting plate to size, drilled a grid pattern for manifold mounting, and machined adjustable manifold mounting blocks. This grid pattern will have aluminum blocks that interface with it to hold up a small portion of the propellant feed system. The adjustability of the grid pattern will allow fast adjustments to be made to the manifold without re-machining. Each of the holes was precision drilled and threaded by the trained structures subsystem members. We also cut and drilled blocks that will allow load cells to be rigidly attached to the thruster-mounting plate system. This will allow for accurate measurements of the thrust from the rocket engine.
