Supercharger in P3Dv4

[edakridge]

I realize that Doug's Turbo/Supercharger dll is 32 bit and doesn't work in v4. Has anyone found a workaround or fix?

Hi,

Doug was nice enough to create a 64 bit version, which is included in my FSX/P3D Base Packs.

EDIT: Doug never created such a gauge, sorry.

Hi. First off, thank you very much for all the planes and your work on the FSX/P3D conversions. Much appreciated.

The supercharger isn't doing anything in the Convair 340. I downloaded the FSX/P3D base packs and use the included supercharger gauge, but it's not working. I did check the gauge and I don't believe it is 64 bit.

Is the 64 bit version included in a different base pack?

Thanks.

Dave

Hi,

I misspoke above; he did create 64 bit versions of other gauges, but not the supercharger gauge. I did ask him back in 2019 if he was interested in creating such a gauge, but I never got a response back.

Sorry for the confusion,

My results are quite close to the RW numbers. I used a combination of Tom's fix and the supercharger thread from FSDeveloper. (Along with a little tweaking) DC-7 Tested in P3Dv5

From the original Ref (My settings in brackets):
Max Cruise (about 1900hp x 4):
Use only to battle headwinds

MAX 41 inches MAP in cruise  (@35 inches MAP)  

FF = 750 PPH(FF=~800 PPH)
RPM = 2400(RPM=2400)(Mixture=19%)

COWL FLAPS = 1 degree
Check CHT  < 232C
SUPERCHARGER to HIGH when THROTTLE => 95% FULL at target MAP

Note:  May cruise nose down due to headwinds at higher altitudes

Plan 3000 PPH
Yields 306 KTAS @ FL200 @ 104,280lbs (50% fuel)
(225 KIAS/307-308 KTAS @ FL 210 @ 119,000)

COWL FLAPS = 0.5 degree
Check CHT  < 232C

Standard Cruise:  @ 0 pitch climb 2000 ft at 500 fpm (FL230 max,
then CALL for MW Econ Cruise, if desired)
Long Range Cruise:  @ 0 pitch CALL for MW Econ Cruise
