BODY POSITI~: THE HANG GLIDER AIRBRAKE

by Tom Peghiny

•

Most h ang glider pilots believe they ha\le no controls in ~ eir glider, but they do. J ust as a 5a;Jplane pilo: ca~ pull his spoilers. and an icarus pilot can,actuate his tip c!ragger, you can use i,.:o:.ir body as an airbrake. Nov.-. every pilot past Hang 1 i<nows that p!one and supine have less drag t~an seaced.

However, few use this co their best advantage.

Let's sta!i with the takeoff. Wai,.' too man~,; pilots attempt to become streamlined immediacely after lau'.'lching. Scalling whi le looking for their fooc stirrup. they wobble back and forth, man>' fall out oi the life and miss a chance at soaring. Ani,.· experienced soaririg pilot uses his CO!'"ltrol to position his glider in the best lift before becoming strearr.lined. In many instances the first soa!ing tum is the critical factor that decides whether the gl:der will soar O! :101. Quite

often it is more comfortable to chermal soar in a crouched prone or semi supine form. }"he first p rone harness made to use chis cechnique was the original Price Prone. For supine sic up and even drop your stirrup if it makes i,.ou more comforta ble. In flight your body can be used for dive brakes when necessary . For instance . yo:.i're ha ppily soaring at cloudbase. during which the conditions overde elop and you find yourself diving to get d01.m th rough rurbulent air. Increasing your bcxly drag v..il! increase your sink rate considerably al max speed. During your spiral/diving descent from cloudbase the extra drag will help keep the gliders speed from going past its VNE (velocity to !"lever exceed). Sailplanes use their spoilers or flaps for !he same purpose. All he previousli,.• me ntioned reasons for pai,.ring more attention to body position are importanl but

When going from prone to standing high drag position. if's important not to grab uorighrs too high because of the poor leverage wnict; malces quiclc turns difficult_ P,101 on right shows /lands in a good position.

it reaU~,r counts on landings.

Whe n rotating out of prone, grip the control bar as low as is comfortably possible.

Holding it higher reduces your leverage and makes quick turns more difficult. Don't grope for the upright. many pilocs miss and ruin their concentration.

The difference in frontal area between standirig form and very supine or prone is 5-6 sq. feet vs 2-3 sq. ft. The reduction in gUde angle is surprising. For an average 8 co l flex-wing , the glide drops to 6 to 1 (chat' s :nax glide; diving or slov.,ing dov.,n v.,ill decrease it more , of course). During your approach. rry assuming maximum drag stance on your downwind pattern leg. The reduced glide angle 1.1,ill make judging your landing easier. This also allows i,.ou to increase your glide angle if you misjudge and are going to undershoot.

The futu re will see improvements in glider performance and top speec:s, harnesses will have to incorporate better drag devices. The ~agrian Prone 1.1.ith the cocoon was the best drag device this sport has seen. When the pilot rotated and removed '1is feei from the cocoon stirrup while spreading his legs. !he body drag was increased to 9- sq ft. That's a major i:nprovement. La:ninar Systems would do well to develop a streamlining system that would rotate 90 degrees for dive brakes. On a modem flex1.1,ing the crossbar could yield a drag area of 8 square feet. A pilot in a previous Hang Gliding issue suggested a parachute similar to the l',.'Pes used

by Air Force fighters and fibreglass sailplanes.

Mani,.' new ideas are possible.As gliders become cleaner the need for drag devices will become more evident. Next time you're watching some seagulls land. note that chey 'ncrease their billow. drop ouc of prone with feet dangling. They rareli,.1 miss their target.

(Hmm. mai,.•be a bird suit would help mi,.· spot landing?) ~ DECEMBER 1977
