Thanks for all your input guys. I only wish I had the time/money to experiment with concepts like this. Sadly I have a real life.. and so it will remain nothing more than an idea.
Umm, the intention was to have wider/larger than normal rotors that spin more slowly. Which reduces the centrifugal stress on them, and the "coriolis" force on the gas. I was thinking some sort of temp resistant composite construction might be possible? I know this would limit speed etc, but...
Can the "coriolis" force be countered by gradually morphing from a round to oblong section pipe of the same area?
btw- I did link to a very crude drawing in my last post.
I think that can be solved by using a continuously variable cross section rotor so that the volume or cross section of the pipe is always constant? And use a slit type nozzle on the trailing edge of the rotor instead of a round nozzle prehaps?
Anyhow, I had 10mins so I knocked up a very crude...
So a jet engine will not work with a long tail pipe? Even if the exit pipe is of the same or slightly greater dia than it's normal exhaust nozzle? That's a problem.
However, by using rearward curved blades would centripital force not help 'move' the air mass towards the end of rotor? And thus...
Mmm, kind of. But the path would be more of a gentle 90Deg radius. The rotors would also be slightly curved to help with gas routing. Also I was thinking of using a bypass turbine as more of an 'air pump'? I'm sure there would be some losses, but even if they were 50% (!) , it would only need a...
Thanks for the info. Seems they were creating the 'flame' at the rotor tips by pumping compressed air and fuel to the tips and igniting it? But they were too noisy.
My idea was to use a micro jet with a long 'split' tailpipe so that the air could be cooled/noise abated before it reached the...
I have seen those. But they all seem to suffer from very high fuel consumption and problems with accurate throttling. But thanks for reminding me as it seems a Dutch two seater called the 'NHI Kolibri' produced in the 50's had 2 x 20 Kg thrust ramjets. Which is great because maybe one person...
If I were to mount a mini-jet engine vertically and direct it's thrust (say 100Lbs) through nozzles at the end of a pair of rotors, via a rotating swivel joint, could I make a mini helicopter capable of lifting someone? The idea being that there would be no torque reaction and only one moving...
Hi, I would like to know if it's possible to create a helicoptor rotor blade that produces equal lift along its entire length? ie- having a profile (chord?) tapered to match the difference in windspeed between the slow moving inner and the faster moving outer sections? Also, it it possible to...
