Unlike the Nausicaa Möwe, the pilot of the OpenSky Möwe does not stand on the Möwe, but rather lies on it with their legs extended behind the craft.

She only stand on the Möwe at low speed; at high speed, long haul flight she always support her waist with a leather belt in a way roughly similar to modern hang gliders and OpenSky Möwe. Examples.

Either way thats awesome. I wish I could own one. Though it seems like it'd make travel really cold.

The design seems practical though I can see nothing where the pilot controls the ailerons. It says nothing about any wind tunnel tests, also there's the small problem of no engine. I'd love to see it fly.

This full-sized model has no engine yet. Right now it is being tested as a pure glider by towing.

The old movie of a test flight of a jet-powered 1/2 model is here.

Thanks for those dormcat. So it's down to developing a small jet engine that is powerful yet light weight and fuel efficient enough to fit inside that size cowling. There is also the problem of how to insulate the body from the heat and flame out the exhaust as heat and fiber glass, or carbon fiber, don't mix well. Also I hope that tow had the combined weight of both engine and fuel on board, other wise it's just a pretty unusual glider. Still it had to feel realy fantastic up there for the while. I want this to work sooo much.

VERY COOL!

Now we only need some armored power suits, and the world will be all gravy!

There are already engines small enough to fit inside the cowling, and jet engines are definitely at the top end of the thrust:engine mass ratio. Unfortunately, they are also near the bottom in terms of fuel efficiency, but that isn't much of a problem as I doubt anyone is going to bo flying long-haul on this.

More like cold, and old-style aviator jackets, hats and goggles (such as those used in the movie) solve the problem quite well.

As long as the exhaust is outside of the fuselage, then heat isn't really a problem. The engine mounting would provide sufficient thermal isolation.


The design itself is fairly viable, it just has no useful purpose outside of a very expensive and fairly dangerous toy.

Agreed, however I wouldn't want my toes dangling just above that exhaust. Nausicaa's mohve had her riding way higher up than that actual design has the pilot. it seems to be actually laying on the wing itself there. also her design has the exhaust tucked way inside that cowling. That would never work for real, not with todays materials. Remember Nausicaa is placed roughly 1000 years in the future and there is much mention about ceramics tough enough to be used as a knife, or sword. as far as I know no such ceramics exist like that today that could be used as the material for a fuselage, not light weight anyway. therefore the actual exhaust will have to be stuck out far enough to be safe enough to both vehicle and pilot.

I really wanted to go to Yokohama this weekend since Worldcon is so much fun. I spent many years supporting the convention and voting on the Hugos, although I have not been a member since 2002 (I must have had around 100 novels signed by various favorite authors at that con) when it was in San Jose. Out of all the conventions I've ever been to Worldcon is by far my favorite since there are hundreds of authors who attend. I actually was standing in line for Frederik Pohl's autograph behind Logan's Run creator William F. Nolan. We passed the time waiting in the line by talking about his buddy Ray Bradbury. It's funny to see authors you respect standing in line with you to get an autograph!

I didn't know that this was the first time it has been in Asia since it seems to migrate to Europe and Canada fairly often. I really want to go to Denver for next year's Worldcon.

There's an interesting new class of materials that are metallic-ceramic hybrids called silicocarbide metals that might be able to pull it off, specifically Titanium Silicocarbide ( Ti3SiC2 ). Its being studied right now for use in next generation jet engines.
