Final implementation of your project:

Design Features:
In the previous iteration of the MMM, the connection sites from the fins to the centering rings were individual L-brackets that required three bolts to secure one bracket to the assembly. This resulted in the entire assembly for the previous MMM to have 90 individual components, making the MMM heavy and arduous to assemble. Cougar Rocket has developed an MMM that has embedded slots that act as connection sites for the fins to the centering rings and has collapsed the previous bottom centering ring and thrust plate, into one combined plate. This will act as a seat for the motor casing and allow for the thrust of the rocket's motor to transfer along the airframe
of the rocket, further reducing the number of components needed.
Team's current progress:
The team has successfully completed the machining and assembly of the MMM. The current MMM has 39 components compared to the previous MMM which had 90 components. Moreover, the current weight of the MMM is approximately 952.54 [g] compared to the old MMM which was 1146.44 [g], this satisfies the project goals for the team. Assembly times for the MMM have yet to be averaged, and the physical validation testing will begin later in the week following the permission of the University of Houston to allow the team to use the intramural football fields.
Team's current level of satisfaction:
The Cougar Rocket team feels satisfied with the amount of work that has been completed with the setbacks faced throughout the semester. The current MMM has reduced the number of parts by over 50%, which in turn has reduced the weight of the assembly. This meets the original project goals as stated within the group's Statement of Work.
Work remaining:
The team needs to finish painting and sanding the G10 fiberglass fins to finalize the MMM. Next, is to perform the physical validation (which is the drop test) at the university’s intramural football fields. Once that is completed, the team will work on completing the technical report and the abstract. As a result, the team will then be completed all the requirements for the course and the project goals.
