Division R Meeting Notes

Meeting 1 – January 18th, 2018 at 10:00 pm

Attendees – Grant Gursky and Kyle Ackermann

Location – Morrison Tower Lobby

Topics

  • Website Development – Kyle
    • Complete profile information
      • Rider needs a picture
      • All need to assign roles
        • Grant – Lead Modeler
        • Rider – Lead Programmer
        • Kyle – Lead Designer
      • Complete approach
        • What is this project about? DRPIE
      • Communicate with company to correct mistakes.
        • Initially the website was groups EPHG
  • Basic AEV design ideas – Grant
    • Single propeller or Dual propeller
      • Decision: Dual Propeller due to stability and possible efficiency (needs to be tested)
    • Braking mechanism
      • Decision: Not necessary if we get the coasting correct
    • Improved wheels
      • Decision: Testing required / possible exchange for another set
    • 3D printed parts / Laser cut parts
      • Decision: Will have to prototype a body design but will design and produce a new body, decreasing weight – improving efficiency
    • Aesthetics
      • Decision: Unnecessary – will add weight and vehicle isn’t moving fast enough nor far enough for aerodynamics to have an effect
  • Program Design – Kyle and Grant
    • Acceleration aggression
      • Will a violent acceleration expend too much energy/ disturb cargo?
    • Run motors / When to Coast
      • Will it be a gradual, slow start up with the motors running the whole time or a pulse of the motors with the vehicle coasting
        • Decision: Testing required but large pulse with vehicle coasting may be the most efficient design

Upcoming Tasks

Grant – Begin understanding the complexities of Solidworks Assemblies and 3D Modeling. Help Kyle with the initial design or the AEV. Brainstorm design for AEV. Find out ways to test the different aspects (may require an apparatus)

Kyle – Begin creating concept drawings for AEV designs/ testing different aspects of the design. Help Grant with modeling direction. Brainstorm design for AEV. Make sure group is competing tasks on time.

Rider – Begin working with the program used to program the arduino. Create programs for testing efficiency. Brainstorm design for AEV. Keep website up to date.

 

Meeting 2 – January 26th, 2018 at 4:00 pm

Attendees – Grant Gursky, Rider Osentoski, and  Kyle Ackermann

Location – Hitchcock 224

Topics

  • AEV Design – All
    • All three members submitted designs (which can be viewed within our company website
      • Varied in design, decision matrices will be needed as well as further testing.
        • Decision: To be determined with real-world testing
  • AEV Testing  – Rider
    • Figured out how to properly work the testing program, creating graphs displaying power input vs time or distance.
      • Will be used later on for testing two semifinal designs.
    • Discovered issues pertaining to the polarity of our motors (are inverse, or they pull air when they should push it, making the AEV travel in the opposite direction as desired)
    • Replaced parts that are damaged to ensure efficiency.

Upcoming Tasks

Grant – Model semifinal/final design in Solidworks as well as physical sketches. Produce one in a timely manner to ensure deadlines are being met. Analyze which motor configurations are most efficient/effective.

Kyle – Build the required models for upcoming testing. Communicate any technical drawing issues to Grant.

Rider – Continue becoming familiar with programming, understanding what code combinations are most efficient. Meet testing requirements.

 

Meeting 3 – February 2, 2018 at 4:00 pm

Attendees – Grant Gursky, Rider Osentoski, and  Kyle Ackermann

Location – Hitchcock 224

Topics

  • AEV Design decision- All members
    • Using a Screening matrix, it was decided that grant’s AEV would be chosen to build.
  • Problems
    • The fans would intersect so it was necessary to modify the original design.
    • This added weight to the design, making the design worse
  • Looked at more specific parts of the design
    • Aerodynamics, efficiency, aesthetics

Upcoming Tasks

Grant – Create a more detailed design of the AEV that has been built

Kyle – Brainstorm ways to improve the current design or possibly start from scratch with a new design entirely

Rider – Begin writing code to test the new design

Meeting 4 – February 9, 2018 at 4:00 pm

Attendees – Grant Gursky, Rider Osentoski, and  Kyle Ackermann

Location – Hitchcock 224

Topics

  • Progress Report – All Members
    • Completed progress reflected on the progress from weeks 1-4 while providing insight to upcoming plans.
      • Preliminary R&D’s purpose was for familiarization with software and hardware. Additionally, introductions to data analysis was provided. Before Advanced testing, preliminary designs were created.
      • Advanced R&D focuses in on testing specific aspects of an AEV. For example, our group will be analyzing the effects of motor quantity. Collecting data for power vs distance, conclusions can be drawn, determining if 1 or 2 motors is more advantageous.
  • AEV Design decision for motor configuration testing – All members
    • The group settled on a design that could incorporate  both one and two motors easily
    • Data collection
      • Conducted 4 trials on the sloped track using 2 motors and plotted the data to see results.
    • Problems
      • The fans would intersect each other so it was necessary to modify the original design, but only slightly. This modification did not add any additional weight.

Upcoming Tasks

All – Conduct trials using only one motor on the same frame and compare results to a dual motor configuration.

All – Consider the benefits and constraints of using 1 motor vs 2 and 3 motors

Meeting 5 – February 15, 2018 at 8:00 pm

Meeting 6– February 23, 2018 at 3:55 pm

Attendees – Grant Gursky, Rider Osentoski, and Kyle Ackermann

Location – Hitchcock 224

Topics

  • Advanced Research and Development Testing – All Members
    • Motor Quantity
      • Determining whether one or two motors are more energy efficient
        • Tested on the official testing track,  one and two motors were consistently powered for 3 seconds, recording power used in Joules and distance. Five tests were completed for each motor quantity and data was compiled. An average in Joules per meter was used for comparison.
          • Initial Conclusion: Two motors seem slightly more efficient
    • Push vs. Pull Thrust
      • Determining whether the motors “pushing” the AEV or “pulling” the AEV was better in power efficiency.
        • Similarly to the testing of motor quantity, both one and two motors were tested in each configuration, using the same code as the previous test as well. This was recorded in Joules per meter and used for comparison.
          • Initial Conclusion: Pulling is better suited for two motors while pushing is better suited for one.
