Hi Naudet,

>What did you modify and can you sent the new one to me via email? (naudet@blackadders.de)

I'm going to have to prepare a releasable version first :-) It has become a bit difficult to handle as it's now, and I'd like to make it more modular so that it can handle different aircraft types.

Does your version already offer the option to enter a separate engine exhaust thrust curve?

Regards,

Hi fats,

>The boost is increased by 2.8 or 4 lb/sq on top of what ever the boost pressure was before the activation of either mechanism. The boosts are not 2.8 and 4 lb/sq.

Good point!

An overview over boost calculations:

Germany: 1 ata = 98.0665 kPa (absolute)
Soviet Union: 1 mm Hg = 133.322 Pa (absolute)
Great Britain: 1 psi = 6.89476 kPa (relative to standard atmosphere)
USA: 1 inch Hg = 3.386 kPa (absolute)
Japan: no idea, as the Aleutian Zero's meter ranged from -40 to +20 it could be inches of mercury

Sure the boost was increased by 2,8/4 lb/sq in

the last line should have ended that way:

standard boost+4 lb/sq in = 1,8 ata

and NOT 4lb/sq in = 1,8 ata


@henning: no my version has no separate engine exhaust thrust curve, just a engine power output curve

did you finally find a way to incooparate the thurst data we had from that FW190 series drag chart?
