Hi, All

 

Just thinking aloud here, I visited a local f= oundry yesterday to collect some feet for a bath-tub which I had made, and = the owner was showing me around his shop =E2=80=A6. One thing which caught = my eye was an impeller he is currently building a mould for =E2=80=93 it is= for pumping air into one of his furnaces, and this got me thinking on the = way home =E2=80=A6.

&= nbsp;

If an impeller were to be cast for this air-induction/super-charging app= lication, and was tied-in to the e-shaft (key-way or similar) would it work= to have a suitable magnet cast-in to the periphery of the impeller, so tha= t two coils could be mounted, 180 degrees apart, to provide =E2=80=98magnet= o-type=E2=80=99 spark to one set of plugs =E2=80=93 one coil per rotor at 1= 80* for a 2-rotor, and 120* for a 3-rotor =E2=80=93 this sounds, to me, so = simple that I am surprised nobody has done it before =E2=80=93 how good wou= ld it be to have a completely battery-independent ignition system for amate= ur-built aircraft ? =E2=80=A6 maybe I should shaddup, & return to lurki= ng =E2=80=A6
