i had just unrolled my G8-2-20 prints on the living room floor engouraged by Luc and Viv to re-explore them.
i never built them because of all the compound curves to work up and i heard from many that there was a bug in the plans that lent low thrust.
now i see the nice job you have done! you shall become Sir Yuk in the knighthood of pressure jet folk soon. please share with us the metal flaring and forming of all those curves someday.
i have to respond to all that are wondering how my old engines ran with just hand tossing over the rotor blades, hope you are all reading. no my engines did not fill the job or i'd still have em but they brought the rotors up to a good speed. as i remember it was like over 150 rpm. with full drag attack (there's one problem). some possible explaination of this might help.
my first engines ran on propane. there was of course 100psi available and i used a heat expansion coil in each to bump up and vaporize a'la Ghluey. missing was a fuel regulator to keep every thing from backing up (problem two).
the fuel nozzle and inlet diffuser were somewhat aerodynamically tuned so the the fuel spray pulled in the air right from the get go. might be part of my success? there was no flame lock device in the plans (problem three) that long pulsejet type tail was not needed because it was more of a ram jet (problem four) so we cut them off. worked just as well.
them suckers did get real hot but somehow did not harm my spruce core composit blades. who knew? i have a good plan for heat isolation next time anyway.
Yuk, keep talking to everybody and we will make that G-8 work.
all the best to everyone and keep up the joined effort,
Has anyone experimented with supercharging a gluey? If so, what kind of increase in thrust did you notice? That is, if you you have the propper setup for measuring thrust. ...Perhaps a question for Luc & Viv. hehe
