Folding Wings, Aircraft Trailers, and Portable Hangars for Inexpensive Storage

Not sure who this is, with the patent on the Dmitriev style mechanism, but it's up-to-date on the fees...

Henryk,

What is that little V4 engine? It looks like weedwhacker cylinders on a homemade crankcase...

 

-I think=it is only macket vor MAX2013 exhibition...\no exhaust,no gasoline instalation\.

=+see propeller mounting\nut...\

 

MAKS is the Moscow International Airshow.

Engine looks like a Wisconsin air-cooled tractor engine, but those weigh too much. Very similar to a Japanese air-cooled V-4 from around 1910, that was used in some aircraft.

 

As for the Dmitriev, it looks loike they've done away with the folding wings, which would make it lighter and far less complicated. If it was me, in order to retain the Leading Edge slats, I'd look at using the automatic ones they add to Cessna's and such, for STOL. I believe they're spring-loaded, then close by aerodynamic drag, when no longer needed. Seen that on Alaskan airshow S.T.O.L. competition stuff.

 

Idea on the engine... Could it be a converted 2-stage/4-cyl. air-compressor? Make it into a 4-cyl/2-stroke engine? Case looks like steel pipe, rather than cast iron, so, Asian knock-off...?

While that may sound a bit far-out, there are quite a few folks that make engines out of compressors, such as sterling and hit/miss engines, for fairs and shows, here in the US.

 

I wonder how well they cool under load though. Not many fins on most air compressors.

 

If it was me, I'd use cylinders from something like a weed-whacker, so you can get a matching piston and rings...

:gig:

Could simplify the frame a good bit with something more like this...
(G-1 Ultralight Helicopter)

... or maybe the Bensen Gyroglider

Just searching those Russian sites and came across this. LOVE IT!

That is definitely a neat airplane!
Anyone know any more about it?
Is it made in Serbia or Russia?

 

=Russia...

there are some remarkable aircraft designed and built in Russia, and not all of them are ugly.
