84 a year ago, 7 October 1932, for the first time, flew into the air of the Stip-Caproni, perhaps one of the funniest aircraft in stories aviation.

Its developer, Italian engineer Luigi Stipa, put forward the theory that an aircraft propeller that drives air through a tunnel should have a higher efficiency than an ordinary propeller. To test this theory, Kaproni built an experimental airplane with a fuselage in the form of a wide tube, which flew quite normally, but showed no noticeable advantages over other machines with engines of the same power. The propeller really increased slightly, but not so much as to justify the construction of aircraft of such an original scheme, moreover, very inconvenient to operate. Therefore, the “flying barrel” of the Stips remained in a single copy, and a year later it was sent for scrap.

It's a pity. A valuable copy of "technology on the verge of fantasy".

Funny design !!!

In hydrodynamics the same. If you put a regular screw in the tunnel, the speed of the craft will not increase. The tunnel will be a simple screw protection. But if you set the screw in a special shape, you get a water cannon. In aviation, propellers of a special shape placed in a tunnel become a turbine.

The history of aviation development is so close in time to the creation and development of technology that there is nothing to be surprised. An example is I-15 and I-16. And the further development of the aircraft industry depended only on the improvement of technology!

And he flew!

Surprisingly, the Italians launched into the sky and not such pilgrims. But it’s one thing to raise a single instance into the air, and mass production is another, and then the Italians were not strong. Managing to spoil even great cars.

Raging fan.
I wonder what ideas the human brain can generate.

Long neighing over a flying pipe Although for those years, the decision was extraordinary. And the main thing is not without common sense. Later, jet fighters (MiG 15,17, etc.) began to make such a principle to the author, respect, raised his spirits

[Peacemaker]

Such an eroplan could be sent to make circles over the territory of the enemy even without weapons. And take them with bare hands at a time, while from his sight, the enemies roll on the ground with laughter ...

In this case, there is no comparison with either the mobs or donkeys.

The Mig 21 was really compared to a flying pipe. But in the case of a moment, the layout of the fighter is associated with a uniform distribution of mass, so that the center of mass is at the right point.

I-16, similar to a barrel, due to a star engine. The designer also reduced the length of the fuselage to increase maneuverability, due to the plumage area. Again does not fit with the idea of ​​the Italian.

Well, the Italian went ahead of the theory using the method of scientific poking. This method, however, does not deserve full irony, since it often and unexpectedly led to the expected result.

It would be better if the author issued a series on the airplanes of the First World War than entertained the audience by jokes.

It does not interfere! Both that, and another is interesting.

[novobranets]

Mom dear, it also flies. Self-transporting wind tunnel. Wonderful, Lord, your deeds.

[masiya]

But there were many funny and interesting projects in the history of aviation, and this is also a peculiar unusual, but nonetheless flying ...

Article clearly +. Thanks to the author! An interesting page from the history of aviation. The article has great shots and even a great video!

The era of naked empiricism. Sometimes it was lucky, but most of it was not very lucky. Yes, of course, a decrease in the inductive resistance of the propeller took place, but after all, it is not the propeller that needs to fly, but the entire aircraft, and here optimization is already needed. From the same, but earlier era - the famous "Ilya Muromets" was statically unstable (the aerodynamic focus was in front of the center of mass), but the time of its revolution was about 9 seconds, during which the pilot compensated for the change in the angle of attack. That is, he kept the device "on the handle" all the time.

however, the time of his coup was about 9 seconds, during which the pilot compensated for the change in the angle of attack. That is, he kept the device "on the handle" all the time

By the way, yes, I read the memoir ... I wondered why it is so difficult to fly a plane ... straight people were exhausted ...

And also the profiles were, to put it mildly, not very, the breakdown at the leading edge occurred at 3 - 4 degrees, and there were no parachutes ...

Just some LOSHARIK!

"Beast unknown to science ..." Funny, it’s a pity that it wasn’t preserved.

Interesting info, did not know, thanks!

This is normal development of aviation. Brainstorming into reality. In practice. The lack of a result is also a result. And those who laugh at this machine - you are stupid! Do you really consider yourself smarter than that designer? For an understanding person in engineering and invention, this topic is cognitive and interesting, and by no means "hilarious".

Looks like a can of cola ... or something like that. A suitable color and for advertising purposes, it also pays off, if built in our time.

The project is not completed. He continued CCS2.
