Pulse jet He-162

Not exactly the model for a quiet, relaxing Sunday afternoon's flying or if you value your flying site.  I think it was at the very first Wings and Wheels at North Weald back in circa '85, that we had a display by an Italian pulse jet team (Giuseppe Dardanello, if memory serves). One of their models spent most of the time during its flights, inverted.  We heard afterwards that this wasn't a display of skill or whatever, but actually because that particular model kept glitching down! Could have been an urban myth but I reckon it was mentioned in one of the many mags we still had back then..

AFAIA, V1 style pulse jets were never used successfully to power a conventional manned fighter - Messerschmitt 328 being an experimental project that proved the engines' unsuitabilty. Strange really, plenty of thrust, good duration, non-specialist fuel and cheap to build. No throttle, naturally.

The thread title is incorrect, the model's a pulse jet powered scale(ish) interceptor

 

The model is a semi scale He162 and is pulse jet powered. What is the problem with the title? 

 

Anyway its not bad at all. the full size was turbojet powered but the layout is ideal for a pulsejet. I assume the omission of landing gear was for weight reasons as the model is clearly quite light for what it is.

 Nothing, now that Paul has changed it.

Yeah, I saw the shape of the pulse jet and guessed it was a V-1. Then I noticed the cockpit and thought Reichenberg, then I noticed the tail and thought Salamander. Now I don't know what to think, lol! Nice model though, and a good glide power off.

In about 1979 or 80, I visited Malta, and met model a couple of model fliers, Joe Anastasi and Chris Vassallo.  Joe built his own R/C gear (not bothering with circuit boards, just soldering the component legs together and compressing the result in a vice for compactness), and Chris, his own engines.  They flew at Ta'Qali, a former RAF station, and had flown pulse jets on single channel escapements (!) there in the 1960s.  Chris built his engines with individual petals in the valves so he wouldn't need to replace them all when one burned out.  I'm pretty sure Chris said they had had some success at throttling the engines by having individual tubes to each petal and controlling which ones were supplied with fuel.
Chris was an amazing model engineer and showed us a huge range of different engines he had built, including hot air, flame sucker, supercharged glow engines, and even an axial gas turbine with eleven compressor stages and something like 750 hand-filed blades.  It had run for about a minute before the turbine melted!  When I find the photos, I'l upload them.

You haven't lived until you have seen a pulse jet engine powered plane fly, it's deafening !,

I have seen 5 in the air at the same time here in France, and a night flight of one with 3 pulse jet engines on it, fantastic !.

There was a display team with pulse jet powered models at the Weston Park show a few years ago. Exhilarating and unforgettable.

   Video on you tube of Ukrainian back street garage guys making and testing pulse jets, the intention is to fit them to flying bomb drones and use against the enemy. Not so much as attack weapons but decoys to give the proper stuff a better chance against air defenses.

Do you have a link to the video, I have failed to find it?

The Germans seem to be fond of pulse jets, here are some more enthusiasts:

So sad to see so many crashes, I have probably seen more than 50 pulse jet flights here in France, and no crashes, they seem to manage to land them right in front of themselves.

France- that's the difference. The Germans are used to building them without return tickets!

But they were launched from France, I was visiting relatives in London when the first ones were delivered 😟.

Very  impressive.

Pity it was not a  V-1. Then is would be true scale propulsion and even the launch method.  

Two  He162 versions were proposed to be powered by pulsejets. One was to have a single 044 Argus pulsejet and another was to have twin 012 pulsejets. They never got beyond the design stage.
