First person to post here with correct identification of this aircraft, wins the "boobie" prize. Ten points added to their forum member post count and the win will be shown in their member rank/status till the next contest winner.

What ever it is????? It looks like it had lots of power :o

AND!!!!!!!

The guy on top of it should be #1 in the B.O.S.S.Society :wacko:

The term "Scared Sheetless" does come to mind.
That is why he is standing in a bucket. Keeps the sheet from hitting the big fan just below. Also to keep his big GoooNads from hanging in the fan.

Sort of like David L. when he contemplates forward flight with his chopper and wind howling at over three MPH. :lol: :P ;)

As far as I can tell it has no actual name, it is refered to as either a Coaxial Rotor helicopter or a captive helicopter for observation. It was powered by three rotary engines, it included a pilot/observer position above the rotors, inflated bags for landing gear, and a quick-opening parachute. It achieved a height of 164 feet (50 meters) and remained aloft for an hour, although it was always held by cables and could not move horizontally. :helicopter:

AND, it was designed by Stephan Petroczy and Theodore von Karman.

PKZ-2 Austro Hungarian Early Helicopter

The world's first real helicopter was built in Austria-Hungary during the last stages of World War I. Yet during 1916 Major Stephan Petrochy proposed the idea of replacing observation balloons by a new-type of machine. He suggested that a helicopter would be more reliable and less dangerous then hydrogen filled balloons. Initially the new helicopter was planned with the installation of the 300 hp electric Austro Daimler motor, but this decision proved wrong because of it being too heavy. In its final configuration the PKZ-2 ("PKZ" for Petrochy-Karman-Zurovec whose ideas and decisions gave a life to helicopter) was a counter-rotating machine with two rotors and three 100 hp Gnome rotary engines; construction was light and assembly easy for transportation purposes. The PKZ-2 was a "tethered" helicopter, with tethering cables retracted by winches on the ground. The observer occupied a special cupola-like basket; he could leave the cupola with a parachute, if necessary. Test flights of the PKZ-2 began in April of 1918. The more powerful Le Rhone's soon replaced the unreliable Gnome's. The helicopter performed more than 30 successful flights, but some problems with stability were still unsolved. On June 10, 1918 the PKZ-2 was demonstrated for military commanding officers; two flights were made with observers in the basket, but others were made without an observer. On the same day the helicopter crashed from height and was slightly damaged. Military command refused the PKZ-2, saying it represented a "high danger to the observer". On June 21st the project was cancelled. Finally, the PKZ-2 was a revolutionary design for its time. Only forty years later the counter-rotating scheme was introduced on the Kamov helicopters in the Soviet Union: other countries generally would not adopt this scheme. And although the PKZ-2 was never used operationally, it really was the first real helicopter and the only helicopter, which flew in the skies of World War One.

Hmmmm, Is it a Thunder Tiger Raptor during the R&D stage?

Kind of looks like a Thunder Tiger Rep in the bucket.



Did I win????




Scott

Well Poot, thought I had a good one here and it was IDed so soon.

We Have a Winner!!

It is indeed a Karman-Petroczy Captive Helicopter.

Congratulations Steve (Mr.Incredible), you have won the "boopie" prize for winning the "Mystery Aircraft Thirtytwo" contest.

Steve receives ten points added to his forum post count total and his member rank/status will reflect his win till we have another new contest winner.

Andrew gets an "Honorable Mention" for being hot on the trail, but Steve got there first.

When I first saw the picture, it reminded me of a "Blade CX" prototype.

Pregnant Idea:
Use a Blade CX mechanics to build a scale model of the Karman-Petroczy Captive Helicopter. Would only need the radio for the up and down part and have it tethered to ground with kite string on spring loaded reels. Or leave out radio all together and mannually let out the tether strings.

Take it to next level and have it full radio controlled and untethered.
Can't you just see that contraption buzzing around field with some little pilot figure in the bucket.

Thank you to all the little people wihout whom I would have won anyway but it wouldn't have been as much fun. :thumbup: :banana: :dance:

I am just posting here to put this topic back on top and give people more oportunity to congratulate me on my fantastic victory. :D

ettu Margo, ettu

We still Loves Ya Steve :wub:

I have another Mystery Aircraft in the can and will post it in a day or two or three.
I think that it will last through the rest of year.

We will let Steve revel in his latest victory and wallow in self-admiration for a little while longer. :hysterical:
