The Ongoing Mystery Aircraft Thread Part Deux.

[Dev One]

Mike, IIRC the gap between planes should be at least one chord to stop interference.

Thanks Keith -I never did get around to studying aerodynamics ! Seems like a sensible ratio.

[Dev One]

Unfortunately Wiki (as usual) has its data wrong, so I cannot guess at the wing chord (103 ft span for a wing area of 132 sq ft???)

Here is another photo I have of the P.R.B. Pretty decent sized machine!




And the next mystery...a little runabout...





Edit: Found a couple more photos of the P.R.B. that I had not seen before. So we know it survived into 1922. Note the large "PRB" letters painted on the nose.

Hi boys and girls!
Nice find of the P.R.B. never heard of it!
Anyway the pictured Aircraft is the De Bernardi MdB-02 "Aeroscooter" of 1959. One copy is shown at the Caproni Museum in Northern Italy...

Sorry for the late reply. Spot on with the scooter BG.

Thanks Moses...Here comes a strange prototype of an otherwise well known Aircraft
Cheers

Looks like the Praga BH-36 to me, BG. Was that not a one-off prototype ?

You're as usual right my dear Lefty! It is the Praga BH36....my stupid comments are due to the fact that some sources (wrongly) maintain that the BH36 was the ancestor of the Praga BH39 or E39...
Therefore your turn please

Still pondering on chord/interplane spacing etc etc, I wonder where this crazy machine fits in ??

[Moses03]

Thought this was Russian, and there she was on page one of Gunstons. Bezobrazov Triplane of 1914. Listed as a fighter!

[lefty]

Yes, an oddball indeed.

Over to Texas

[Moses03]

Here is a contemporary of the Bezobrazov. An oddball in it's own right.

[lefty]

As it doesn't have a propeller, and has wings made of recycled cornflake packets, is this another April 1 special ??????

[Moses03]

Real, and did fly a couple of times.

The engine is running in the first photo. Note the tail section that is attached by a ball joint.

[Moses03]

The tailwheel was spring mounted, ahead of it's time. The metal machine made a couple of flights in the Niagara Falls area...

The investors did not think they were getting their money's worth so they started taking parts of the plane to sell off...starting with the carburetor! Eventually it disappeared.

[lefty]

Presumably the 'tail unit' went back to the washing machine whence it came......

People really invested in that ?????

[dan_pub]

the only airplane that can wag its tail...

[lefty]

The only thing I can find to match is the Weidmann Flying Tank - 'reportedly flew'

Aye, right*, as we say in Scotland - that's what the 'investors' were told.......


(*You know how two negatives make a positive - well this Glasgow term is the only known example of two positives conveying a negative!)

[Moses03]

It is the Weidmann. An interesting machine for 1910!

Over to the lowlands-

[lefty]

Something a little more modern

Hi Mike
Maybe a Yourfeng?. But forgot what number

[lefty]

Not Yourfeng, Walter,but Mifeng (as I'm sure you knew ) In fact, the Mifeng-11 from the Beijing Institute of Aeronautics and Astronautics.

[wout]

Hi Mike!
I knew this one, but since you were so kind to supply me with info on the Mifeng-11 a couple of weeks ago, I called it the Yourfeng in the hope other members would react.
To be honest (which I try to be most of the time), I wanted the chance to post this floater (amphibious) parked in the back yard. It was twin engined (the cowlings are still on top of the wings) with tractor props. I have reasons to believe the mystery aircraft was actually flight tested.
I have a sketch which gives a better idea of how it looked like and will post that later.

[wout]

No takers?
The aircraft is US and may have been completed around 1969/1970. The picture was taken in 1985 and I cordially invite better photos of this one-of-a-kind twin .
