The beginning of this project was deliberating what methods we wanted to use to test the efficiency of propulsion system using flippers and how to model it. Our first step was researching current methods of systems that exist. We found that mimicking the same movement as animals that have fins such as dolphins, turtles and other sea life would be …
Greywater Recycling Week 4
Every senior design project has to start somewhere, and during week 4, we four members of the Greywater Recycling Project met together for the first time and started discussing details. We had briefly met as a group with Dr. Walter during week 3 to get a basic understanding of our project and what we will be aiming for over the …
Circular UAV Project : Midterms Incoming
For the past week, our Circular UAV project team 1) finished the proposal for UROP. 2) estimated the budget for our current design. 3) started the CAD model for the wind tunnel test. 4) calculated the power requirement with the basic performance metrics from the previous week. 5) met with Terry for process review and signed up for a peer …
Circular UAV Project : Basic Requirements
For the past week, our Circular UAV project team 1. updated the weight estimate for the current design. 2. came up with some basic requirements for our Circular UAV including, Rate of Climb : 600 ft/min Range : 3 miles Endurance : 15-20 minutes Stall speed : 16.13 ft/sec (hand launch) 3. calculated the wing loading, wing area, and aspect …
Circular UAV Project : Beginning
The Circular UAV project aims to design, build, and fly an unmanned aerial vehicle with circular wing configuration. In the beginning of the designing process, we need to roughly calculate the weight of the vehicle, collect information about parts, and decide which to use. So far, we got together and 1) decided to use one of the airfoil types between …
It’s Alive!
After some late nights, we finally got Savage up and running again just in time for a track day. Last weekend, Anteater racing went out to lot 16H where we set up a skid pad and an acceleration strip to run some last minute tests before the design for the next generation of Savage starts. All is well until the …
Smitty has saved us yet again!
Our problem with centricity was that we had no feasible way to keep our wheel centric on the axis of rotation. Hub-centricity was not possible, as the hub hole had been cut away for “weight saving” purposes. Lug-centricity was out of the question, as a technical judge required us to obtain permission from the wheel manufacturer to countersink our lug …
The ethics of “lug centric” vs “hub centric”
A racecar’s wheels need to be mounted to hubs – in our case, there are five studs sticking out of the hubs that hold our wheel on with lugs. However, because there is some play between the holes in the wheel and the lugs, there needs to be a method of keeping the wheels from moving around on the hub; …
Battery Boxes
This week has been a week of manufacture. We continued fabricating our battery boxes which have been produced from 0.09” 6061 T6 sheet Aluminum and look, up to now, exactly how we designed them. We now need to weld the sections together and electrically insulate them to complete them. This task required more man hours than we estimated which we …
Venturi Design and Manufacturing
In the last two weeks, we have managed to have the engine running well consistently. Some minor fixes included correction of the engine timing. Thanks to the hard work and expertise of our head engineer Rich Hack and collaborator Max Venaas at the Advanced Power and Energy Program, the Generac system has been successfully connected to our existing load bank …
