Performing vibration testing 📳💻📳 of components which will be on our rocket is a crucial step in validating our systems before flight. Vibe testing ensures that components will function nominally when subjected to in-flight vibrational loads without ever needing to leave the ground! Last Friday at the University of Michigan College of Engineering Space Physics Research Lab, our vibe testing team tested a solenoid valve which is used in our rocket's tank pressurization control system to maintain a constant pressure in our propellant tanks. The test setup included the solenoid mount, vibration adapter plate, plumbing arrangement, and an autoscript to test valve actuation, all of which were made in-house. The solenoid valve performed nominally during the entire test, meaning that it is cleared to go on the rocket! Here we can see Rohun Athalye and Tyler Linfesty who were accompanied by Emilee Seghi and Cameron Sahagian-Crandall. #masa #engineering #rocketry #b11spacechallenge #rocket #rocketscience #umich #uofm #goblue #aerospaceengineering #aerospace #space #vibes #vibecheck #testing #vibration #mechanical #manufacturing #rocketry #controls #iterate #iterativedesign #iteration #safety #team #engineer #research #pressure #solenoid @michiganengineering ![Keeping our engine fed is complicated business!

Keeping our engine fed is complicated business! Here is a photo of our pressurization board, designed in-house by our avionics members! The press board ensures fuel is fed into the engine at a constant pressure. It dynamically adjusts the position of a motorized needle valve using typical PID feedback control. Previously, ATLO team members observed one motorized valve moving incorrectly. During this worksession, frmr. Avionics Lead Marion Anderson (@parkourbot) and frmr. Safety Officer Paige Adams (@paige_is_social) identified aberrant behavior in the motor's control signal path using an oscilloscope. They were able to confirm that the issue originated from bad solder joints on the on-board microcontroller. Now that the solder joints have been fixed, and the control signals are correct, we can move forward with engine testing! . . . #engineering #rocketry #b11spacechallenge #rocket #rocketscience #umich #uofm #aerospaceengineering #aerospace #space #goblue #testing #test #testing #pressure #manufacturing #equipment #electricalengineer #electrical #electric #electricalengineering #electricaldesign #pcb #controlsystems #controls #avionics #iterate #iterativedesign #iteration #safety #team @michiganengineering @michiganaero ![Handling LOX is an integral part of our testing process, and here we can see our former ATLO...]()
Handling LOX is an integral part of our testing process, and here we can see our former ATLO (Assembly, Test, and Launch Operations) Lead, Alfonso Botta-Lopez (@el_spaino) filling a dewer! We hold LOX trainings every semester to get our members properly trained to handle it, and we have one coming in the next few weeks! . . . #masa #engineering #rocketry #b11spacechallenge #rocket #rocketscience #umich #uofm #mgineer #aerospaceengineering #aerospace #liquidoxygen #rp1 #kerolox #space #goblue #liquidpropulsion #testing #nozzle #propulsion #machining #test #testing #production #machine #pressure #manufacturing #equipment ![Another prototype LOX tank is here!

Another prototype LOX tank is here! This is our third liquid oxygen tank, developed by the Structures subteam and is roughly 8 feet long and 15" in diameter. The tank is made of Aluminum 6061 and welded using 4643. The tank is now undergoing ultrasonic weld inspection to look for any imperfections in the welds. After inspection, the tank will be heat treated to close to its pre-welded strength and then hydrostatically pressure tested to failure, which we hope will validate our design and manufacturing process. We built this third tank because our first two prematurely failed thier pressurization tests. Live and Learn! Huge thanks to Custom Tech Fabricating for the welding, United Technical for the inspection process, and Modern Metals Processing for the heat treatment! #masa #engineering #rocketry #b11spacechallenge #rocketscience #mgineer #umich #umichengin #uofm #goblue #aerospace #engineering #space #liquidoxyen #production #manufacturing #development #mechanical #kerolox #liquidpropulsion #testing #burst #welding ![We're pleased to announce that we have placed second on Phase 2 of the #b11spacechallenge!

We're pleased to announce that we have placed second on Phase 2 of the #b11spacechallenge! Phase 2 is the final design phase of the Base 11 Space Challenge, in which we took our initial designs for Tangerine Space Machine and refined them into designs that are flight-ready and ready to go to space! We are now in the manufacturing and testing phase, ensure that all parts work as designed. Thank you to all of our wonderful team members, our sponsors, and of course @base11stem for the opportunity to compete, and congratulations to @spaceconcordia and @ubcrocket ! . . . #masa #engineering #rocketry #b11spacechallenge #rocket #rocketscience #umich #uofm #mgineer #aerospaceengineering #aerospace #liquidoxygen #rp1 #kerolox #space #goblue #spaceportamericacup #space #innovation #design #engineers #thankyou #team @uofmichigan @michiganengineering @michiganaero ![TTS testing is underway!

TTS testing is underway! This is the Thrust Transfer Structure, which mounts the engine to the rest of the rocket. We crushed this prototype with a hydraulic tensile tester to ensure it will withstand the full thrust load. The colors overlaid on the video represent strain in the part, measured using Digital Image Correlation (DIC). It survived a maximum force of 9,240 lbf before buckling, meaning that we have a safety factor of 1.8! This marks the first successful test to failure of a flight system for TSM. . . . #masa #engineering #rocketry #b11spacechallenge #rocket #rocketscience #umich #uofm #mgineer #aerospaceengineering #aerospace #liquidoxygen #rp1 #kerolox #space #goblue #liquidpropulsion #testing #propulsion #test #production #machine #stressanalysis #simulation #safety #manufacturing #digital #mechanicalengineering @michiganengineering @michiganaero
