Unmanned Gliders Seek Lift
From the AvWeb AvFlash news:
Unmanned Gliders To Seek Their Own Lift "Automated on-board energy aware planning" is being developed by the U.K.'s Roke Manor Research to allow autonomous gliders to find naturally occurring lift and sustain unpowered or prolong powered flight, according to a report in ElectronicsWeekly.com. Ultimately, aircraft equipped with software and hardware that actively processes video feeds of cloud conditions and surface type (cool grass, or hot pavement) data would be processed along with other elements (models assessing weather and predicting vertical air movement due to thermal and orographic lift) to identify thermals and share that information with similar aircraft nearby. With that information, a virtual and real-time lift map could help produce waypoint sequences for use by integrated flight management systems aboard the aircraft as they hopscotch from lift-point to lift-point along a route. The aircraft would literally be led to their required destination via a route that applies all acquired information to avoid areas of sink and exploit the best areas of lift between the departure point and destination point. Current proposed applications for the developing technology include extending the flight range of unmanned aerial vehicles. |

Wonder if this is where we will see thermal sensing instruments
developed. Probably eventually trickle down into our cockpits someday.

We already share them with birds, cornstalks, plastic bags, and the occasional airliner - to say nothing of random 2-33s flown by student pilots, intently staring at their non-compensated mechanical vario for any sign of lift! That almost qualifies as a UAV itself! More thermal markers, too. I think it would be cool - and the UAV would probably have better thermalling etiquette than a lot of pilots out there... BTW, I bet if you had a transponder, the UAV would be programmed to avoid you like the plague! Kirk 66 |

A UAV as thermal sniffer? Yikes!-Those things will probably be controlled by
software, written by humans -Forget it. Instead, rely on million of years of systems testing, bring an eagle along (would look awful when you open the doors to the Raptor Compartment!)

Put the whole kit and kaboodle in the glider, send it around the course
while you stay in the club's bar, and then go out and catch the wingtip when it lands. Pretend you flew it and turn the flight in to the online soaring contest -- that is unless an FAA representative is there and notices the alcohol on your breath, but you can explain the situation to him and turn the flight in later.
