P-51D Prop Windmilling (2.0)

When the engine is turned off in the P-51D, the prop will continue to spin slowly when a headwind is present.

The slow speed that the prop spins is affected by the speed of the headwind. :book:

I have witnessed this in 1.5

This has been around as long as I can remember with the P-51.

I too have seen it in 1.5 and earlier and reported it before. I am just bringing it up again pointing out it remains in 2.0

its been there since 1.2, nothing new, and not uncommon IRL when props aren't secured into a headwind, i doubt its a bug.

Really? :doh:

Is the compression that low in a Rolls Royce Merlin that a 5 knot head wind is enough to freely spin a 12 cylinder, 27 liter engine over? :lol:

This. It's not uncommon on say other aircraft perhaps (haven't seen it myself though), but with a Rolls Royce Merlin? Absolutely not. :)

I agree with Mr Busitil. The propellers on an internal combustion engine will not windmill as modeled. A turbine engine will which is way you see the props secured when the aircraft is unattended.

An internal combustion engine will windmill in flight as a result of engine failure due to the airflow across the prop at a speed which can maintain flight (lift) which is why they need to be feathered during an engine failure. Windmilling.

I would proffer that it depends on the engine failure - if a sudden seizure in the cylinder head occurred could not the momentum of the propeller be enough to either strip the reduction gear or cause a fracture in the prop shaft thus leaving the propeller free to windmill?

Of course if it's simply a case of user selected engine shutdown in flight then I'm with the school of "gonna need a bit more than 5 knots to turn that sumb***h over!"

Thanks for acknowledging, Yo-Yo!

I was in a P-51 in multiplayer yesterday and had all my settings the same as

1.2 and 1.5, but in 2.0 I experienced a very strange popping noise in the

engine when I was taxiing and turning. It sounded really great but I had

never heard that noise before and I wondered if that was a 2.0 change for

the sound or was something wrong going on ????

I love the popping!

In Germany, poppen has a ... special meaning :music_whistling:, but the statement would still apply
