    (another) question about C Beaty's rotor

    I couldn't find one in LODR catalog, or, at least, i couldn't see it. i guess we wil have to ask rotorway... isn't the mosquito using that kind of bushings?

    Attention computer experts

    Chuck, svchost is a process that is used by other programs . the fact that it appears in your task manager is quite normal. BUT svchost is sometimes used or faked by spyware and trojan worms. you better check your computer. you can block it in your firewall with no damage. i recommend Sygate...

    (another) question about C Beaty's rotor

    that's it. i actually wonder if this system could be adapted. Or maybe we could shape the fixed hub and the floating hub, then mold an elastomer, to reproduce the same effect+replace the bushings. Chuck, you really know a lot of useful products and manufacturers, have you got an idea where i...

    (another) question about C Beaty's rotor

    Hi Chuck, oh yes tip jets are wonderfull in many aspects... yes torque is a problem, your arrangement sounds good, we also plan to use pseudo-laminated bushings to have axial softness but radial stiffness. I have read the Shafer catalog and had a look at the refecence you gave me and it sounds...

    (another) question about C Beaty's rotor

    Hello Phil, Chuck. Chuck, excuse me if i don't explain things very well, yes it is collective/compression coupling, not d3 link. Thank you for the information, it seems that this problem is going to be a serious issue. i had a look at the SHAFER bearings and i don't know if they can worl...

    (another) question about C Beaty's rotor

    Chuck, Thank you for your fast reply, as usual. Yes i meant the tilting allowed by the rubber bushings. 5° sound stiff. i would be grateful if you could tell me if you encoutered some resonnance problems due to the rubber bushings. A friend of mine, while we were drawing some ideas, told me...

    (another) question about C Beaty's rotor

    Hello Chuck, as you know, i find a great interest in your "floating hub rotor" and it happens that a rotor could be built using that system. If you don't mind (and if you ask no fees :D), i'd like to ask you 2 things : 1 - if you could measure it, what was the angle of "flapping" allowed by...

    Flying trailer

    My friend Xavier Averso sent me this video of Michael Obermaier, designer of the DF 02, of a test performed on a 900 kg trailer (1800 lbs). If you never saw a flying trailer, it's worth watching the video. http://www.gyrotec.de/images/Videos/FlyingCarTrailer.wmv

    Tip Jet Helicopters

    Mike, glad you joined the discussion and i think you are an asset in the debate. i don't understand how you determine the HP required to run the procharger 564 HP !! (the engine must be at least 1500 HP or more to have one !!). the rotrex numbers are not exact. here is a message i got from...

    VTOL Gyro at Oshkosh, maybe !

    YES, the turbochargers are designed to reduce the pipe lenght from the exhaust to the hot turbo intake, yes heat is energy and a loss in heat in a turbo charger is a loss in power. If you cool air you reduce its pressure.

    VTOL Gyro at Oshkosh, maybe !

    Mike, i already had seen the applet from nasa, but it works for rocketry :D Ok i just try to sat logical, i maybe wrong buti assume that the DJiNN worked with an airflow of 1 Kg/sec and i just try to find which device could do that. I think the nozzle is not the only element of the problem...

    WARNING: scary flying photos, mountan top private research jet labs, unknown devices

    Tim, those are very nice shots, that is what i call flying. i'm surprises you didn't have trouble flying over the jet lab... You know...the men in black..:spy:

    VTOL Gyro at Oshkosh, maybe !

    WOW ! that's GREAT !! I hope it will fly, the forum members know that i try to push this concept further for yesars, even in France, and i'd love to see it fly, that would prove that we can do that. People are skeptical about tip jets here and it's tireing.. way to go !

    Question for Mr C. Beaty

    Thank you very much Chuck, your explanations are very precious for my understanding. I perfectly (or quite) understand how your rotor works. You didn't invent the principle of the floating hub but you proved that you can build a rotor w/ cyclic and collective control simple enough to be made by...

    Question for Mr C. Beaty

    Phil, i agree with your statement, now. Chuck, that's what was tickling me : did the drag cause some noticeable vibrations. You didn't answer about the aerodynamic center. it should not be the same as the hub center or am i overkill ? in my drawings, i plan to place 4 bushings (or maybe a...

    Phil, are you shure of that statement ?

    Question for Mr C. Beaty

    Thank you Chuck, i didnt expect an answer so fast ! in understand the advantages of your rotor and i'm still asking : the rotor, in flight, is subject to dissimetry of lift, so, drag, does the elasticity of the hub allow the rotor to absorb the advancing blade extra drag/lift in addition to...

    Question for Mr C. Beaty

    Hello Chuck, times ago you sent me some pics of your rotor and i have some questions about it : this rotor does'nt need lead/lag hinges but can it be absolutely rigid ? i feel not, does it need somehow a flap hinge or some coning ease ? , i feel yes and you rotorhub was designed that way you...

    Empathy

    Vance, i discover, with this thread something that i suppose has taken some of your thoughts. You explain very well that some "accidents" cannot be condemned "at first glance" and that hazards don't happen because the designer is a bad person but because that person takes the risk to build a...

    Electrically driven rotor concept for future rotorcraft.

    Let Me Explain Let Me Explain ok, i forgot to mention WHY my interest in tip jets for gyros.. first, i live in France where the regulations about ultralight airplanes, including gyrocopters if a very tolerant one (ask our UK friends!). you can build and fly your own machine, that's your very...
