    Dynamic Soaring takes advantage of differeing wind flows seperated by a thin wind shear boundary. Recently the record for radio control glider reached 392 mph (peak speed is over 400mph, but the convention is to measure the uphill return speed:

    The current record is 468mph. I made an animation that explains the mechanism in simple terms, by analogy to an elastic collision:

    Here is a NASA project based on dynamic soaring:

    Yeah, these guys have reached a level where you need high-speed cameras. I wonder if at some point they will reach the barrier of human reaction time, and replace the manual steering with computer control, guided by GPS or some local transmitters.

    I made a new version of the animation.


    Most explanations I saw concentrate on the gain in airspeed when you pierce the boundary layer. My main aim was to show where the gain in groundspeed happens, because that's what gets measured by the radar gun.
