Oddball engines and prototypes

[Frits Overmars]

I reckon that up till then, he was accelerating and was getting wheelspin on the "dog collar" running on the tyre and he just pulled the engine down a little more snugly - well, that's one theory!

I haven't got a better one.

BTW what would be your estimate on revs - 30,000 ?

We do not estimate, Sir. We perform video and audio analyses .
They tell us that top speed is 36 km/h (five seconds from one yellow snow marker to the next one, fifty meters further on) and rpm = 1200 .
With the same over-all gear ratio and Ryger-revs he would do exactly 900 km/h. No problems with the sound barrier yet, but maybe his tire rating won't allow it .

[Flettner]

I love it. But did he really change gear at 1:05? How??

No, he just opened her up. Released the choke?

[WilDun]

No, he just opened her up.

The bottom end on your machine might not fly apart (or contract 'osmosis') if you adopted the lubrication method he uses, it's obviously so good that he can keep it running without any need for a cover (thus keeping it cool) - what the hell is osmosis anyway? - a disease or an inferior grade of oil?

Why are you Dutchmen always so precise? - we would just estimate it and reckon that there was one 'bang' per lampost! (every pine tree in this case).

I know some of you blokes like plane stuff, so have a look at these Russkie fighters.

I have seen some russian demo's before, but nothing as comprehensive as that.
It is amazing the propaganda we are told, but those Ruskies have some real interesting tech and physics working there.
Just imagine how advanced their drones may be?
The west does not have any aircraft capable of some of those maneuvers, let alone training pilots capable of withstanding the forces they are exerted.
Just staggering stuff to watch.
Thanks very much for posting the video.

Yes, we have been fed a lot of propaganda about those guys, but it's just as well they can fly because their infrastructure including their transport/roads in the important areas leaves a lot to be desired (not to mention their president!).
But in saying that, never underestimate their ability when it comes to aircraft, in fact never underestimate them at all! - Sikorsky in the USA, (an expatriate Russian) showed the world the way in helicopters.

Not just him, although I thought he was Polish. remember the Russian space pen that cost millions of Dollar less than the Nasa one.

Ground effects craft
Note: The 6-engined jet at 0:40 is the Antonov 225, which is presently the largest aircraft in the world, period. Its a cargo transporter and its cargo bay is so large it can hold most of the assembled components of a Boeing 747.

[husaberg]

Ryger anyone.

Do you have an old Renown or Davis Pump in the shed Neil?

I also found these air engines. they make more sense than all the other clean engines I have seen.
Up to 70 degrees at tdc

He was Russian I believe, (without asking uncle Google's opinion) - then remember, Russia is comprised of Swedes, Finns, Germans, Poles, Ukranians, Georgians,Turks, Mongols, in fact you name it - these people have lived there more or less forever and are all Russians! - Boundaries are man made, but genes don't recognize boundaries!

That is indeed a mighty machine but it might have to remain on the Black Sea - Caspian Sea maybe? Had read about it somewhere before but haven't seen this stuff as yet but I will soon!

I haven't googled either yet but there is a video (not in Russian) about them they use a lot less fuel than a plane. I understand they use ground effects plane in the Caribbean you can also buy kitset ground effects flying hovercraft.

From my experience with compressed air motors in the workshop, they are bloody inefficient and you don't need a detailed analysis to tell you that! Your average sized air compressor will be struggling to keep up with even one small vane motor used a lot, the concept has been around for a very long time but has never been used in automotive stuff (except for starter motors and brake systems on trucks etc). Better off with a generator and electric motor I reckon.

Don't really want to pour cold water on it all, but that's how I see it anyway.

PS I do like those ground effect flying machines!

And where does the energy come from to make the compressed air in the first place, real inefficent!! A three horse motor to drive a tiny pencil grinder via a compressed air energy transfer, I'll bet these air engines are a French idea.

Acording to the blurb $2 for 120 ms (around town) This engine is a little different, maybe watch the videos
Whilst it will be hyped, it seems a better alternative than fuel cells. Yes foggy tech and in production as well I think with Indians.

[WilDun]

A cording to the burn 2 dollars for 100 km around town the engine is a little different maybe watch the videos

The fact that it was mooted in the eighties, the fact that the technology has been around and the fact that it's still not in use, doesn't give me a lot of confidence in a successful introduction.

Then, (as always I could be wrong!)

I like it. It can be charged quickly. 2 minutes.
Uses availabe technology. I also like the linkage which is why i actually posted it.
Its an around town only thing.

This is worth a look to.
