Procedure

Goals / Objectives

Knockoff Criteria

  1. Turn on drone

  1. Set waypoints

  • Create a simple path for the drone to follow.

 

  1. Run main obstacle avoidance script

  • Ensure no errors.

Bring drone to the flightline

 

  1. Set up the obstacle in course

 

 

  1. Battery plugged in

  • Mission planner no pre-arm warning

  • make sure AUTO is in one of the flight mode

  1. Bring the drone to the flightline

  • toggle safety switch

  1. Enable logging

  1. Arm the drone and set mode to AUTO

 

 

  1. Let drone start flying through waypoints in AUTO

  1. Wait for drone to approach the obstacle

  1. Ensure that drone stops and enters LOITER mode

  • Ensure the drone stops ~10m away from obstacle.

  • Ensure drone switches to LOITER mode upon detecting obstacle.

Drone If the drone does not stop within 10m of the person and obstacle:

  • Person The person holding the obstacle steps out of flight path immediately.

  • Pilot manually intervenes and skips to Step 13 (landing and disarming drone).

  1. Remove the obstacle from the flight path and ensure the drone reenters AUTO mode

  • Ensure the drone resumes its mission.

Drone

  • Ensure drone switches to AUTO mode upon obstacle removal.

If drone does not resume :to landing waypoint

  • Pilot manually takes over and proceeds to Step 13 (landing and disarming drone).

  1. Drone hovers over the 2nd waypoint (the landing waypoint

  1. Drone auto lands

  1. )

  •  Ensure drone completes the mission.

 

  1. Pilot manually intervenes and lands drone

 

 

  1. Disarm the drone

  • disarm the drone, Toggle safety switch

Necessary Preparation

Explain what capacity you need, what needs to be mounted, etc.

💻 DEBRIEF

Flight test debrief report

  • Please upload the picture to media digest!!!

    • updated thanks a lot

  • Weather is a huge thing

    • Glad doesn’t risk and fly in heavy rain

    • Next time plan ahead of time

  • A prop just break during transportation

    • suspect overtighten issue

    • replace one props

Card 1 Test 1

Info

Flight planning

  • Take-off, full stick deflection, and engage autotune

Flight test card requirements/objectives Performance

Panel
bgColor#E3FCEF

Control performance & payload situation

  • Control feels OK to Yuchen Lin in althold and loiter

Note

Identified issue

  • Autotune does not start (drifting)

  • wait for the weather to be clear

    • next time need better planning

Warning

Issue need to be RCA

  •

Control performance & payload situation

  • Control feels OK to Hardy Yu , report drifting a lot issue in loiter (maybe setting and stick center)

Note

Identified issue

  • When attempted landing, one prop break and fly out

    • result: instable in landing and crashed

    • no damage to the system

  • The other two prop are having crack

  • Conclusion replace three props in total

Warning

Issue need to be RCA

  •  

 

return to service

Info

Flight planning

  • gentle takeoff and control check

Control performance & payload situation

Note

Identified issue

  • Two of the regular nuts for props are loosen in the flight are cause thrust lost

    • result leads to crash

Warning

Issue need to be RCA

  •  

 

Tip

Did not risk any valuable component and don’t have any issue with the rest of the system

none of the other system got damaged

Warning

Haven’t finish any objective for the day

need seperate session for pilot training

flying props are dangerous

Need to respec the props

Evan Janakievski will be available on 27th → next pilot training session time

Update on July 12th:

Smile Khatri Point out during July 6th flight test, The propeller normally come with a black ring at the bottom of the prop. The reason for the prop failure is that the ring was not installed, and when the motor spins, stress accumulates across the injection moulding edge. [need mech clarification]


Smile Khatri Can you add a photo of the black ring? thanks

The second lesson we learned is that Loctile is not suitable for a prop and might damage the prop. Also, it takes a long time to solidify, so if we use Loctile during flight test, it does not have any effect.
