Stable Gyroplane Platform ?

[PeroxidePropuls]

For me it is amazing to see how stable the Hiller Flying Platform was! You can see it fly here: www.peroxidepropulsion.com/files/Hiller_Flying_Platform.wmv

If one took away the duct (like the PAM Platforms) and installed a propeller on the platform and let the rotor rotate free, it would be a Gyroplane Platform. Right? Would it be stable if one also put a horizontel stabilizer on it and located the center of thrust were the center of gravity is?

Personally I belive it might be stable, despite the pilot was standing on top of the rotor! At an engine out situation I believe it would flip over, so the rotor went to the top and the pilot would go to the lowest point of the craft (If he could hold on to it!)

What do you think? Should we build one and see what happened?

It would be a very small rotor, Erik.

Build it....no. First you have to complete the test with perioxide on my Powered Gyroglider :) - as we have talked about.

Hi Jens,
I have no intention to build a Gyroplane platform right away. I was just qurious if someone on the forum had an idea if such an odd craft could be stable, dispite the pilot was standing on top of the rotor.

I will be glad to let you test my tip rocket system on your Powered Gyroglider, with your Para motor, because I could than prove my theory that a gyroplane could be driven with a small propeller engine, if the rotor is partially driven.

You have to stand in line, though, because I have already agreed with a gyroplane friend to test the system on his Humla (Bumble Bee in English) right after midsummer. After that we can move the rotor system over to your Gyroplane Glider frame.

Jens, I think a lot of forum readers dont know what we are talking about. For you that are interested can go to my web site and read more: www.peroxidepropulsion.com/article/27

I have seen your site before, and have to admit that peroxide propulsion does offer some promise, and Im thinking in particular of the Fairey Rotodyne type of application ~ prerotor, sans the rotor pitch adjustment. The unit displayed seems well presented.

My concerns are in the handling and use of peroxide fuels, you would recall the Russian Navy Kursk incident, involving the high speed peroxide powered torpedoes (some 70 knots), and this was not the only submarine to fall fowl of peroxide fuels.

Also there is the question of availability of the fuel, as I recal visiting the local pharmacy to aquire about a pint of peroxide for cleaning purposes, they were innitially reluctant untill I provided identification and stated the purpose.

Gabrial,
You are right the two big suppliers of Rocket Grade Hydrogen Peroxide, Degussa and FMC, are quite strict in their selection of customers. I am more easy to deal with.

I am busy starting up a new plant now, but I have produced and delivered RGHP already just to convince myself everything is working. with transport and distribution. I have sent RGHP to customers in Europe and US. It works fine. You just need to buy enogh product per shipment, lets say minimum 36 gallons, to keep the shipment cost on a reasonable level, (One 0-roll Gyroplane take-off takes about 1/4 of a Gallon).

I dont know what the Russians did, but I know they had a mix of organic fuel and peroxide, wich is more risky to deal with, than the monopropellent rockets I use. Hydrogen Peroxide/Parafine torpedos made by the Swedish SAAB Underwater Systems, have been produced many years, and they are still produced, without a single accident so far. But again one should not compare with my monopropellant rockets which are very plane, simple and safe, even if the power yield is lower. I use 80 to 85 % concentration while the military and the space industry use 90 to 98% concentration.
