I removed the 62" Hornet blades and replaced them with my 49" blades.
Some time back I posted a chart 13 diferant motor conversions, Hornet, tape drive, tredmill, Garbogen, dual disc with Lowes ceramics and the 403.
At 15 mph the 403 was doing 144 watts nothing below this mph. At 30 mph I was seeing 325 watts. This is less than Paul Gipe got in his test.
I was thinking my test may be showing higher #s do to being truck tested. However my #s are lower than his on the 403.
Hopefully this means my other test #s were not over stated either.
Heres a list of gennys the did over 95 watts at 15 mph and there blades size.
Garbogen 49" 250 watts.
SW403 46" 144 watts.
1.5 hp conversion 3 phase
49" 123 watts.
6 pole furnace conversion
49" 120 watts.
GE ECM at 48 volts
49" 120 watts.
moded Hornet 49" 95 watts.
Big TDM 55" 144 watts using blade extensions.
All these units have my plastic blades accept the 403.
The mast on the test truck is in the bed. The wind coming up over the hood and cab could be excelerated? But if so my 403 #s should be higher than Paul Gipes 403 #s?
The mast is 7 ft.
I still plan on building the wind tunnel.
I gather the data from a very nice analog amp meter, Fluke true rms multi meter and the trucks speedo. I checked the speedo with the State Police road side speed indecator, the thing that tells you your going this fast and its off by maybe 1/2 mph at 55?
I usually average wind speed in 2 directions to accont for prevaling wind.
