Why still no dive acceleration difference?

[Crumpp]

Speed is an important concept in combat, just like altitude. Pilots know what's the best altitude for their aircraft, eg, P47D, are willing to fight fw190/bf109 above 6000m altitude. If fly a La7, the lower altitude, the better. Why altitude is so important? one reason is "engine output".So is speed.

All of this comes out in standard performance calculations. In this case, subsonic incompressible flow theory works very well at predicting subsonic propeller design behaviors.

For example, you don't have to add anything when crunching the numbers for a FW-190 regardless of the propeller.

If you plug in the data for a metal propeller, your drag is less which means less lift and your sustainable turn performance envelope is reduced.

If you plug the data for a wide chord wooden propeller, your drag increases resulting in more lift and your sustainable turn performance envelope increases!

It is all in the math!

But one fact is very clear: prop efficiency may lead to hundreds of horsepower difference above Vmax, so a simulation game must pay enough attention to detailed efficiency curve. otherwise, a big difference from history is inevitable.

What is the basis you will manipulate the curve? Propeller design is extremely complex and once again, it is too easy to spot a bad design very early on. Like first flight early, LOL.

This appears to be a license to manipulate aircraft behaviors based on intuiation and supposition.

Propeller design is just too complicated and easy to spot a bad design. There is a reason why a generic curve is acceptable!
