Title: Propellers that looked feathered.
Post by: Kenne on December 22, 2013, 06:24:03 PM
When the eng on a multi eng AC fails.

or do i just use the 'RPM' key to do such?

Feathered props are not currently modeled visually.  They are modeled in flight behavior though.

Anybody run a game test to see if feathering the prop increases gliding range after an engine failure on single engine fighters?

Single engine airplanes don't have feathering propellors, added weight and complexity is not needed.

Reducing RPM on a windmilling prop does reduce drag both r/l and in AH.

I get tickled when I see someone landing who is a little fast and they shut the engines off since by doing so they are decreasing drag, not increasing it.

Single engine planes do not feather the prop, AFAIK. In twins this is much more critical because the off engine creates a lot of drag that yaws the plane towards the dead engine. This is very dangerous when flying at a slow speed (rudder ineffective) and applying full power on the good engine - like when losing an engine immediately after take-off.

Feathering the windmilling prop reduces the total drag of course. Twins are supposed to keep on flying on one engine, sometimes to quite long distances. Single engine planes were not supposed to fly 400 miles back home with no engine. If you were flying a single engine plane and lost the engine, the extra drag from the milling prop is the least of your worries...

In the twins, the yaw is the bigger issue than the total drag, and this is irrelevant in single engine planes.

Getting the prop to stop windmilling is the key to a long glide but you had better  be at high altitude when you try it because these planes seem to windmill down to 38mph or less so an unusuccessful attempt to stop the prop will lose you precious altitude.

Thanks for getting be straight on the single engine prop feather.   

Icepac I had noticed a stopped prop seems to help.

In the P-38 it's automatic.
