I'm pretty sure the V-1 pulse-jet flying bomb used a rocket to launch and get up to flying speed. I don't recall whether it was a solid fuel rocket like the contemporary American JATO, catalyzed hydrogen peroxide monopropellant. or a liquid rocket with hydrogen peroxide oxidiser. If I had to guess I would say the second. Doug Woodard St. Catharines, Ontario, Canada On Thu, 1 Sep 2005, Manzo, Emil wrote: > Hi Doug. 400 mph...oops...just a minor detail.

Hi Doug. 400 mph...oops...just a minor detail. Of course you're right. The SCRAM jet is the super-sonic version (supersonic combustion ram jet). I think the old German V1 (buzz-bomb) used a variation on the pulse jet that had a front-flap, allowing starting from a standing stop using only the turbine. It was quite advanced for the time.

Hi Joe, for no (very few) moving parts you need a ram-jet. Or as some used to call a “scram jet”. It is essentially a pipe with a venturi and a fuel injector. It needs to have air flowing through it before ignition, like if it was attached to a glider or vehicle. Once enough airspeed flows, the injector is activated and the fuel ignited producing thrust. I bet WVO would work for fuel J. Another one of my hair-brained dreams….

Awesome. The jet engine is too noisy in my opinion. We just viewed a really cool movie called Winged Migration. Now that's the way to take to the sky. Man has never done a flying machine that even comes close to the way birds fly. beautiful & graceful. I am content to watch.

That's a good question Joe. Right now, I'm just collecting information. So, I couldn't tell ya. Since bearing life is a function of load and RPM, it's hard to say -- High revs and low load.

Hi Joe. When you said Pulse-jet you reminded me of something I saw when I was a kid. It was a small jet turbine that bolted onto your car’s differential. It bolted in place of the rear differential cover and connected to your fuel and electrical system. As the car ran down the highway, the turbine came up to speed and you could flip a switch and inject fuel into it for a boost. Primitive but effective. I bet one of these would run well on biodiesel.
