At the A.N.Tupolev Kazan state technical university under the leadership of professor V.A.Pavlov a supersonic vertical takeoff airplane with retractable main rotor is created ....

If that thing's supersonic, I'm the Space Pope.

The model has a certain hoaxy look about it, like some of Unicraft's more whiffy products.

It's nice to see that Russian aviation designers also read Secret Projects Forum:

http://www.secretprojects.co.uk/forum/index.php/topic,3954.0/highlight,modus.html

http://www.secretprojects.co.uk/forum/index.php/topic,898.75.html

;D ;)

Anyway, supersonic or not, is there anything technically impossible about this configuration (retracting-rotorblades-turning-into-diskshaped-wing) ? Mr. Pavlov, it would seem, is not the first to stumble across it.

All together now: "ALL HAIL THE SPACE POPE....ALL HAIL THE SPACE POPE....ALL HAIL..." (accompanied by bowing, scraping, kneeling, assorted genuflection, et.al.) ;D

I suppose Prof.Pavlov have asked his students to make a model of this flying something, so amateur first year teenagers have produced this cadavre.

I think Vic Morrow was the first to stumble into it.

Just call me Ray said:
Holy Space Pope, it just dawned on me that the fuse is a Horsa!

Well, obviously. What else would you do with a plywood and fabric glider than make it VTOL and supersonic??

Next up: the VG, turboscramjet powered SPAD.

Shouldn't that be the "ACME do-it-yourself, easily assembled VG, turboscramjet powered SPAD. One previous owner (W. E. Coyote)" ? ;D

Brilliant! I'm working on it (can we replace the turboscramjet with a regular pulse jet)?

Hi,

At the A.N.Tupolev Kazan state technical university under the leadership of professor V.A.Pavlov a supersonic vertical takeoff airplane with retractable main rotor is created in which generally different scheme of blade retraction is used making the structure lighter and compact, thus more attractive for use (in figures, the flying model for testing the lifting system is presented).During the transfer to the airplane mode of flight the blades are retracted inside the disc wing.= The retraction takes place in the plane of rotation at the expense of kinetic energy, therefore, there is no need in additional reduction gearboxes, transmissions and power units. For this, geometry of the flying vehicle is not changed, so the danger of transitional modes is sufficiently lowered.The structure of the lifting system of the given flying vehicle unites the advantages of main rotor with those of disc wing having a wing profile in the cross-section. The round in plan shape gives two benefits: the first one - the stable flight at any angle of attack up to 90 degrees, thus excluding spin even at the lowest speeds; the second one - the excellent mating of the disc with helicopter way of creating a lift.On the basis of the given scheme in KAI are developed the projects of supersonic rescue-airplane, recoverable spacecraft, high-speed vertical takeoff airplane for domestic freight and passenger traffic.
