Well, screw the helmet idea!Â* Who needs the weight?Â* If you're gonna go that far, why not a set of light weight glasses with a bluetooth receiver built in and all of your flight and collision avoidance information focused at infinity through the glasses kinda like a HUD.Â* Cockpit sensors would track the glasses and adjust the picture to the viewing angle. Agree on the weight - what I'm thinking is more like a shell to hold the visor, electronics, mike, earphones, position sensor, cooling fan (why not?). More like a bike helmet than what we used to wear. Glasses are OK but the field of view is limited - If you have tried a Hololens vs Oculus Rift you know what I mean. I would want the "HUD" to have at least 200 degrees of FOV so it would show traffic that I'm not looking directly at. Anyway - all the cool sports wear helmets - chicks dig them! Kirk 66 |

My wish-list of what should be feasible today:
*Pylon or shoulder wing. The Mü31 or a bit more radical. *Ditch Schempp-Hirth drag brakes. They are heavy, complex and require an enormous amount of man-hours to build. Use "crow-foot" flaps instead, a bit like the AS system, but much more extreme. *3-piece wing that's mounted on top of the fuselage. By using such a mid-wing you can drastically reduce structural wing mass. *Use the above to build a 10m2 wing with an AR of 45-50 that's no heavier that today's racing class. Easily do-able with a sparless center wing and pultrusions. *FES, with a raised main gear so you can take-off. *Reduced battery pack for the FES. Replace that with a 5 HP 4-stroke generator and you loose all drawbacks of FES. |

Race cars use spectra as part of the crash protection structure. Wonder why gliders have not copied from race cars?

You mean the tethers that keep deck lids, fenders, and the like from flying into the crowd?
Probably not needed in typical Sailplane crashes... |

No, and spectra is way too expensive to use for deck lids, fenders... It is in a lay up.

I believe kevlar is used in the cockpits of the "safety cockpit" Schleicher gliders and probably others. A mix of carbon/kevlar seems to be common in the seatpans of new gliders these days. |

Interesting, as in sailing we have kevlar sails, but spectra lines.

Spectra is a polyethylene material. Kevlar is an aramid. Mike |
