Within ERAU’s Virtual Hub I designed a UAS for a simulated missing hiker mission. The specific system I selected was a DJI Spreading Wings UAS - Condor Octorotor. The reason I selected this was mainly for the way it looked, but also assumed the amount of rotors would provide better stability to unknown disturbances and wind turbulence.
The UAS performed positively after some trial and error during the design phase. Communication range remained at a moderate level during design no matter what configurations I chose. This was due to the fact I was using the man portable GCS. The trailer GSC provided for 100% communication range but with the missions terrain and elevation I assumed it would not be a feasible choice in real life.
During the mission I kept running into the issue of the UAS crashing and burning. I believe this was due to the speed that was initially set to 80 m/s. I then set the speed to 60 m/s and that appeared to be the perfect pace for the UAS as it did not overheat or crash. Altitude needed to be set above 70 m as any level set below caused the UAS to crash into trees and catch fire.
Overall the mission was successful with the remaining battery level at 73% and communication signal at 68%. I never found the hiker, but the UAS did land at my designated point successfully. If I had to complete this assignment again, I would choose a different mission and GCS that provided for a 100% communication signal level. This would ensure a better success rate and overall mission completion.
