excellent vid to chuckle at... :ok:

hang on, where's the tail rotor on that beastie? :confused:

HOGE 2nd Apr 2006 19:25

I presume it was a tip jet rotor, like the Djinn.

What a great way to get to work....if it wasn't raining.:}

Sweeeeet...............I remember a couple of those things which are now in Museums. Some may be here if you visit the states. http://www.armyavnmuseum.org/index.html
The US Marine Corps had one also, very similar.

The last time i have seen anything like that was outside asda, and i put 50p in it for my daughter to play on it :}

Which ASDA?

The one that has the kid's helicopter ride outside :=

"I presume it was a tip jet rotor, like the Djinn."

Correct: "..it's only power coming from compressed air generated by the engine.."

Was that Nick Lappos ?

Here's competition; http://www.unicopter.com/1009.html

It's packaged in a torpedo tube. :ooh:

The jet engine provides compressed air to the rotor tips, hence no torque or need for a tail rotor. I don't know for sure but I assume it also uses directional compressed air jets in the tail for yaw control.

The Dornier 32 E/U was an ultra-light single seat helicopter designed by Dornier, which started flight testing at Oberpfaffenhofen on June 19, 1962. It was a collapsible helicopter with reaction drive which could be carried in a car trailer which also served as a take-off and landing platform. Stowed in a special transport box, the helicopter could be stored anywhere, ready for operation, and was easily carried by air, sea and land. The two-blade rotor made of light metal was driven by compressed air leaving through blade tip nozzles. The drive system of this reaction helicopter, free from anti-torque moment, consisted of a turbine-operated compressor made for easy handling in operation. The Do 32E was practically a precursor for the unmanned "Kiebitz" ("Pewit") rotor platform. The Do 32 U autostable, remotely controlled rotor platform was derived from the Do 32 single seat helicopter. This experimental unit was used from June 1966 for basic testing for the future tethered unmanned "Kiebitz" rotor platform.
Dornier built a total of three prototypes of the single-seat helicopter. Since the German Ministry of Defense (Bundesverteidigungsministerium) was in muliseater though, additional models were not completed.

The Dornier Do.32 was one of the first helicopters designed and built by the German helicopter industry after the war. It was a small, ultra-lightweight single-seater which could be carried in a container of modest size, measuring 3.8m long and less than 1m wide. The container was fitted with wheels, could be towed by an ordinary motor car, and also served as a take-off and landing platform. The mini helicopter could be assembled in just five minutes.


The Do.32 was powered by a 100shp BMW 6012 turbine which drove the rotor through a cold cycle. The prototype was tested on 29 June 1962 and completed the test programme in mid 1963, when the German company displayed a second model at the Paris Air Show. A few others were built but the two-seat derivative (with a 250shp turbine) offered to the German government was not adopted.

My own theory:

The yaw control is through the flow of air over rudder, as a conventional airplane.

In a hover, the exhaust from the turbine will provide that flow...just a theory.

I probably would, at least in a hover. I'd be wearing a really good helmet and a back brace, just as if riding a sport bike :} .
The US version was designed by Hiller, and they have a nice display of one "flying" via ceiling-mounted wires and also one that is still in the drop tank configuration.
I took a couple pictures at the Hiller museum in San Carlos, CA, USA in 2004:

I thought I had some shots of the indoors displays mentioned above, but I guess I don't.
