titleSummarizing Recent Flight Tests

  • Daniel Puratich

  • 2023-11-18 Flight Tests

    • Tuned Three Axies successfully on Houston!

  • 2023-11-19 Flight Tests

    • New camera mount pog

    • Flew drone manually

    • Collected images on first flight

    • RPi did not work after that

      • suspecting temperature?

        • if temp was around zero,

      • Low voltage on power

        • possible issue on buck converter or temperature

        • looking at RPi readout

        • should temperature test buck board

        • possibly wiring voltage drop is the issue as well?

      • Should check temperature operating range of all autonomy components as we get into winter

titleAirframe Structure

  • Conall Kingshott Nathan Green Jonathan Di Giorgio

  • Frame is currently disassembled following the flight test

    • arms removed currently

      • nothing was noted wearing early

      • should inspect holes? Conall Kingshott will look tmrw, but should be goooooood

    • wear that happened to wires is most likely from monster mount install so not going to focus on correction to the rest of arm stuff

    • awaiting heatshrink for wires to reassemble

  • We considered options for removing thread-to-wire contact in the system

    • Conall Kingshott thinks this isn’t necessary. Do others agreedisagree?

      • Bolts that aren’t threaded on the top in such a way that would address this are not easily available

    • Lots of effort, likely wasnt the problem

titleAvionics & Battery Shrouds

  • Andy Zhang Conall Kingshott Alison Thompson

  • Shrouds are made and cut

    • done on bandsaw instead of waterjet bc pre thin

  • layups that were done last week are good

  • Gotta look at connecting them to clips.

    • Will use some sort of adhesive.

titleCustom PDB

  • Tom Chiu

  • From last weeks EE meeting:

    • Majority of technical details related to choosing voltage divider values into ADC figured out after taking into account the equivalent circuit in the ADC that contributes to the input impedance.

    • Finishing up LTspice simulation to try to validate proper equivalent input impedance after taking into account the shottky diode and low pass filter.

    • Still trying to figure out pros and cons in deciding to put RPP across the input voltage from the batteries or just the input into the 5V and 12V buck regulators.

titleSystem Harnessing

  • Mena Azab

  • Bullet connectors soldered and frayed wire repaired.

  • Will need to order more 16awg wire unless we know where the remaining wire we ordered in the summer went.
