Autonomous Soaring

Autonomous Soaring

In the pioneering spirit of the Wright Brothers taking flight in North Carolina, I am teaching a computer it can use thermals like hawks and buzzards. As a PhD student at North Carolina State University in the Aerospace Engineering program, I aim to demonstrate an intelligent embedded system that finds and uses thermals to increase time aloft.

The project goal is 141.7mi cross country without human intervention. This will beat the 1988 FAI world record for cross country flying by 1 mile. A milestone is to beat the 25.3mi goal-and-return FAI world record set in 2005.

So far, a 30.2mi goal-and-return (60.4mi round trip) flight has been achieved, beating the current world record by almost 5 miles. The unofficial record breaking flight is documented and posted here. The flight is unofficial because the FAI model aircraft category does not allow autonomous systems and newly created UAV class does not currently have a glider category.

Come with me, as we make glider history and create an enabling technology: autonomous soaring!

Finally a good flight test

The eSBXC had a good flight test yesterday after hurricane Ida *finally* left us alone. After 4 straight days of rain, the ground was completely saturated with water, leaving us with promise only of a mild day, once the fog and clouds finally burned off that is.

I made a test dolly with some new plywood wheels to attempt getting the eSBXC off the ground without aid of a winch. Thrust-to-weight ratio is rather low (for better cruise performance), so I knew that takeoff performance would be anemic. The winch flights showed there was plenty of pull-out power with this propulsion system, so it was simply a matter of getting the airspeed needed to...

Flying on a yucky wet nasty day was still a success

I have never flown on a day where I landed with a dripping airplane. This was a first. It’s not like it was raining as we were flying, but misty drizzle might adequately describe it; I had to wipe the mist off of Brady’s glasses. Martin guessed cloud deck at 1000ft and it was lower than that at times. Tom and Martin took turns off the winch set up the short way across the field. The wind was from almost due North and quite cutting. Both guys commented they had some miserable flights, but it looked like they had fun! Brady and Martin flew hand-launch a bit between drizzles.
