Powered Paragliding: Analyzing the Forward Launch

This style of photography along with some Photoshop work allows close analysis of a light-wind launch. Chapter 4 contains many tidbits for trouble shooting such launches but this may help. A full resolution version of the picture appeared in September, 2006's issue of Powered Sport Flying magazine (pictured).

Notice how much is happening in frames 4, 5, & 6. The wing, which starts off stalled, gathers increasing airflow down the back and accelerates upward while the pilot only moves forward a few steps.

Initially, hands are mostly back and the pilot has throttled up just a bit so that, when the wing gets overhead, he can stand up straight and the motor thrust will accelerate him quickly--that keeps the wing from falling back. With nearly zero wind it's important to avoid pulling any brake until the wing is up and you're moving nicely. The wing did fall back a bit but he had enough speed to prevent it going all the way down. Be careful, even though this is a soft-framed cage, most instructors recommend using NO power on such units to prevent the lines pulling cage parts in the prop.

In this nil-wind condition, the pilot pulls essentially no brakes until he has gathered significant running speed. 

Trimmers are set to slow for a lower liftoff speed but, if your wing tends to fall back, setting them to a faster setting may help with inflation at the expense of a slightly higher liftoff speed.

Tim Kaiser performs a flawless forward launch with a soft cage unit. There was, at most, 1 mph wind when this was taken. (Click for larger image).

There are many variations depending on your cage, wing, conditions and difficulties. Techniques vary with power use, body lean, layout and trimmer use.
