Break To Do List

Avionics Jim/Louis/Mary all of break

• ADC for load cell (waiting on load cell pick)
• Implement motor (waiting on motor pick)
• Ground Radio implement and scrap
• Scrap has to load cell, parachute, sensor package, arming, telemetry, airbrake control, power, missing one

Recovery Avionics

• CAD (blocked by component selection) Mary and Jonah 3 Check in/done ish the 6th
  • Fiberglass wall onto structures, make sure it implements with recovery bay and airbrakes (perhaps not using bolts like last year)
  • Fit all electronic components in ave bay while still being able to access everything and have 4 screw switches holes
    • Worst Case 100mm with all components done 19th
    • What has to go in there? *louis stuff to pick and check with everyone done 19st
      • Big red B
      • Pick load cell (force on airbrake is max 0.90 kg plus, Waiting on Nate to give mass of airbrake as steel times 6g's )*
      • Cots flight computer(s)*
      • Scrap*
      • Motor*
      • Arming switches
      • GPS antenna*
      • 900 mhz antenna*
      • 70 cm antenna*
      • Wiring/connectors*
      • 4 Batteries*  
        • Big read B battery
        • 2s battery for servo and camera
        • 2s battery for main flight computer
        • 1s battery for Scrap

Recovery 

• CAD Nate Done 19th
  • find volume of components 
  • subdivide the bay
• FEA Nate Done the 6th
  • ensure survive snatch force of 314 lb
• Spec drogue for 150ft/sec  Hayden Done the 6th
• Spec streamer for 30ft/sec at 3000ft Hayden Done the 6th
• Scaled model of airbrake Hayden Done the 6th
• Ask about jolly logic
• Ask mark about flight computer

Airbrakes 

• Simulink model to check code Sam
• CAD-Nate 1 All Done 12th
  • Load Cell Implementation
  • Implement with ave bay
  • Pick a 20 kg servo 
  • Make airbrake thin and heavy (steel)
