Thank you

When at Harrogate doing test firings of the flash steam hydro a young chap (everybody seems young now) from Paisley had a very interesting talk about the steamer and many other things.

He talked about many R/R turbine blades that had been discovered and some of his projects especially his pulse jet.

I thought it would only be small until I looked on his website that I found when I received a parcel today with his name on it **LINK**

I had mentioned about lubrication problems on the steamer and I use solid lubes mainly so he sent me some coating to try plus a turbine blade with test certificate.

When you meet young people with a passion for engineering there is hope for the future of our hobby.

Thank you Wilson Logan for the natter and the lube I would like to talk to you again.

I have spoken to Neil about email notification problems it seems from a person who eventually contacted me via another website that they are getting bounced possibly I am classed as a Spammer and get blocked by ME website security? that I am not as security spam checks make me clean..

He's building a full size V1?!!

There was a bloke in NZ who was building motors that size, he thought he might be in the market for a cut price cruise missile, but I think that idea got shut down, there is a video on line of his jet powered go-cart.

The lad is getting some good welding practice. Ian S C

Those of us in the Jet and Rocket engine community are not building models, we are building to actual size. There is a whole other world out there my friends, and it has nothing whatsoever to do with coal or traction engines.

He actually did build a cruise missile — minus explosive payload — but got shut down by the NZ gumment, who also sent the taxman after him.

But he has published details here so you can build your own if you want…

Hi Paul,

Not so young, I'm 48! Although in the pictures I'm nearer 40.

I made two large flap valves instead of the Luftwaffe approved valve grid. Didn't work.

So I had to down the valve grid route:

These are about 1/2 the size of the valves I will eventually need.

I made a wax master followed by an RTV negative followed by a more durable resin positive.

Here's a link to pictures of the turbine blades and stuff we found in Rolls Royce's QA dungeon:

Its all titanium with a smattering of some very hard, very magnetic, very corrosion resistant stainless. Or it might be a chrome steel. Not sure. Whatever it is, HSS won't look at it and carbide doesn't like it either. Well, not on my Bantam. A bigger lathe like a Triumph or Excel might be stiff enough.

Cheers,

Wilson.

I just noticed the plasma circle cutter I made out of scrap.

It was actually a college course where you could come along with an idea that involved welding and machining and learn 'on the job' as it were. I was the youngest there by a long way. Most of the guys were in their seventies. It was an ideal learning environment for me as most of them were life long engineers.

For those not familiar with the V1 rocket motor, it was in essence a two-stroke engine with a reed valve inlet, and a resonant exhaust system – just like many more modern motorcycle (etc) engines. Except – and this is the clever bit – the engine had no crank, piston, etc – the reed valve was connected directly to the exhaust. Power came not from a rotating crank, but from the thrust of the hot gas emitted from the exhaust. There had to be an ignition system, to light the mixture after the resonance had drawn it in – but I think this was a simple coil ignition and a small battery. Or was it?

Cheers, Tim

Walter Kaaden was one of the men who worked on the V1 then in peace time used that knowledge to develop MZ two stroke racing bikes in East Germany.

Their star rider Ernst Degner took many of MZ's secrets when he defects to the West.

Suzuki then got them and that started the domination of the Japanese bikes.

The V1 used a spark plug to ignite the fuel (fairly ordinary petrol). The pulse jet engine used was designed by Paul Schmidt and Fiesler built the airframe. Apparently the V1 was 1/6 the cost of a V2, and with British bombing intensifying and Luftwaffe losses increasing, they sat up and took notice.

The engine needed to have ram air to get it started and this was provided by a catapult launch powered from a H2O2 steam generator. Flight control problems were studied with the aid of the extremely brave, extremely petite and extremely skilled test pilot Hannah Reitsch, who flew the beast to learn it's handling characteristics. Unfortunately, neither her brains nor her beauty nor her awesome piloting skills could gainsay the fact that she was a committed Nazi.

I have an interesting pdf paper on German rocket projects (though not including the V1) called "Wunderwaffen". PM me if you'd like a copy.

Carl.

Was a very good book written about this called "Stealing Speed" written by Mat Oxley ISBN 978 1 84425 975 5
