2023-09-20 Mechanical Meeting

Comp frame project explanation and check-in

@Conall Kingshott

• Show CAD

• Weight check in and manufacturing technique explanation

• Work on Cabin, mounts, and shields in next ~2 terms

Antenna tracker explanation and check-in

@Arjun Mandair

• Show CAD

Fixes that need to be implemented

• Lessen overall weight and material consumption

  • Will help with overall inertia of the system

• Lessen amount of set screws utilized on shaft

• 90 degree sheet metal bend instead of machined block

• Supports on servo mount

  • Also beef up overall design of servo mount

• Sensor mounting

• Waterproofing

Questions

• Continuous rotation servo?

• Servo on plate instead of bottom?

  • Will make the sensor mounting weird or difficult

  • May need to increase plate size

  • Increase overall inertia

• Servo Wire tangling?

  • Slip ring?

• Wiring antenna tracker to ground?

Will Update Asana after confirmations!

FEA/SIM explanation

@Smile Khatri

• Software we can use: SolidWorks simulations, Ansys Fluent & Ansys for FEA and CFD

• Simulation workshops starting late September

  • Workshop 1 will go in-depth about CFD, fundamentals of aircraft aerodynamics which will help us make our drone more aerodynamic

  • opportunity to learn Ansys Fluent (popular software for running CFD sims)

  • Workshop 2 will be focused on FEA, static and dynamic sims. I.e. we can use FEA to determine whether our landing gear can withstand the impact from the drone landing

• Ansys Fluent CFD tutorial for finding drag coefficient posted on Confluence

Monster Mount

@Smile Khatri

• Currently, the plan is to have the Monster Mount on the drone arm. I forgot the reason as to why we chose to have it on the arm. Is it possible to make a mount attachable to the bottom plate of the drone (w/o interferring the payload)?

  • The key concerns were

    • landing gear leg appearing on the camera’s peripherals/vision

    • vibrations on the arms since the mount is closer to the propellers
