Hi,all!
I know this isn't e-bay, but I know the
exact formula for the timing of Klaus' PLASMA I,II,III NA, HC, and Turbo! What
am I bid?
In a chemically-correct mixture, it only requires 0.5
milli-Joule to obtain ignition. PLASMA's put out in excess of
120mJ.
PLASMA l&III have multiple, opposite polarity sparks
that really excite the molecules in the intervening gases which
then get very hot, hence the name PLASMA. Notice: this spark is a very
light violet color, almost transparent rather than blue, and a piece of
paper put in the gap will ignite!
In all this discussion of timing and thetaPP, no one
has mentioned flame-front propagation speed vs charge density.
Litton Industries and Hughes had D-Sub connectors on their approved list for spacecraft. 'Course,
gold only, not tinned!
Now for a request. I fly a 235 with an
O-235, 9.7:1 CR, putting out about 123 SL hp at 2800 rpm, with dual PLASMA I
ignitions and an ELIPPSE three-blade prop with 76" effective pitch. I have
extended wing tips which add about 2 sq. ft. and 20" span. I get 1550 ft/min ROC
at SL, 2420 rpm, 110mph IAS, 1350 lb. At 1000' dalt, 2950 rpm I get 214 mph
TAS; at 10,000' dalt, 2800 rpm, I get 201 mph TAS, and at 14,500' dalt, 2750
rpm, I get 198 mph TAS at 5.8 gph. These numbers were all obtained with a
highly-calibrated pitot-static system, true OAT, and a GPS. I would like to
get comparative data from those of you who fly 235's. Thanks!
Paul
