It’s remarkable how fast a quarter happens. Time flies when you’re having fun, or an engineer putting in back to back hours trying to balance your classes, work, internship, and any extra-curricular activities. For the Spacecraft Thermal System mechanical team, this quarter was a productive one. Our goal this quarter was to complete construction of our thermal testing chamber. The …
Hello readers, As the quarter draws to a close, parts and materials have been received and finalized with various testing going on. Our Avionics team has been testing several motors to better understand power required to run each motor with different propeller sizes and how much thrust each setup can produce. We used three different motors for tests with propellers …
This week, we changed the size of our rotating frame for improved stability for testing and for use by the Air force. Instead of using 1x1in bars, we used 2×2 which immensely helped the stability of the frame. we were also able to begin testing the rotation of the plate. we were able to test the rotation o f the …
During week 7, we posted a picture with 3 different symmetrical pieces that we received. The three pieces were welded together this week to form the lever arm. Welding is a fabrication process of joining the two rods together. This is achieved through fusion, where the two metals are melted. The next step is to send the welded piece for …
We wanted to find the error of our data using the root mean square (RMS), so we looked at 7 images for each data point in the graph shown, and separated the channels (RGB channels) and calculated the RMS using MatLab function. We eventually analyzed ~200 images, and found only a small error. We have been preparing another test set-up …
We have talked with Dolan and finished all the paperworks about 3D-printing. Currently, they are 3D-printing, we would get the product this weekend. After that , we will combine all the pieces together and it will take around 1 hour. The project is off the track a little bit, but we think we will have something to show in the …
The update from this week is a summary from previous weeks. We are getting to the final step of our prototype. Last week we had a presentation and it went well. This gave us more confidence on our design concept and we will work harder on improving the prototype. An optimal design for the mechanical system has been reviewed by …
Although last week we were able to successfully control the speed of the spooler, problems rose with the different types of plastic being extruded out of the extruder. By running tests at 60 seconds and 120 seconds, we were able to find the rate at which plastic was extruded in grams/seconds. We found out that virgin pellets were extruding at …
This past week, Bon Kim and Damian Torres met up with the 3D printing club to print a prototype of the fins (pictured). However, there were technical difficulties when they tried to print one of their designs, which includes hinges in between part of the fin to make it flexible. I worked on the poster for our presentation at the Winter …
This week we finalized the presentation details for our peer review and started to work on our design poster. In our peer review presentation, we wanted to include our revise budget, the timeline for the quarter, who we selected as our sponsors, potential roadblocks and the progress we have made to manufacture our CAD design. In addition, a draft of …
