Pulsejet on an Eindecker??

Geoff · October 13, 2016, 05:30:57 PM

Ok I have entered a club build where we are all doing a Fokker EIV. I was thinking about a ducted propeller or a pulsejet. The pulsejet had been invented before WW1. So if I squint a bit - - I was thinking a pulsejet powered parasite fighter from a Zeppelin.

Tadpole type engine mounting with a skid for emergency landings if it cannot reconnect with the mothership zep. Proper wing control surfaces and ridged bracing not wires. Bigger tail. Yes it has to be this kit and no I cannot kitbash mods to have to be scratched, so it's got to be simple.

Or a very simple colour scheme job of an angry clown for a warped "flying circus".
opinions?

?

I'm not sure but I think the ducted propeller had been invented before WW1, too.

Now, if contra-prop gearing had been, as well ...

Quick check of Google shows that "A contra-rotating propeller was patented by F. W. Lanchester in 1909." in the UK. Here: https://en.wikipedia.org/wiki/Contra-rotating_propellers

OK! Now we have it!

A contra-rotating, ducted propeller E.IV Eindecker with a belly-mounted pulse-jet in an "angry clown" scheme!

What he said. Except for the angry clown bit

This should be a real head turner !

Well I for one like the idea of a ducted fan

Maybe a float plane ? Straightforward pusher, no interupter gear ?

Steer well clear of clowns with them being all over the news and that

. Never really liked them even as a kid. There were exceptions though - Carolli, Wisdom, Mr Pastry.

I have been thinking maybe a ski equipped plane launched off of a ramp on a gun turret, and recovered onto a towed pad. The pulsejet seems to predate the ducted propeller, but didn't work without a separate power source.

Looks a bit like the coanda jet plane......

The problem with early pulse-jets is that they lacked sufficient power to attain fight speed from stationary; however, once they got some forward velocity, they could maintain airspeed & could accelerate quite quickly to their maximum speed.

I have this image in my head of a mini diorama, of the aircraft being launched and just reaching the end of the ramp with the wings and tail feathers being ripped off by the slipstream as the fuselage bursts into flames from exhaust.

I just wonder what it was like for the pilot ? Asbestos underpants ?

I think Gerry Lee Lewis may have had the answer!!

Yep I think it will have to be a Coander fan.
Nice build Caveman!

The Coanda Morane-Saulnier was built by Frank Henriquez aka 'frank2056' and 'Frank3k', the 1910 Coanda by 'Gabriel Stern' (the nom de maquette of artist Claudio Luchina).
