Identification question

Kenneth’s explanation is is spot on.

As far as I understand that system, the pitch of the propeller is related to the speed at which the small “fan” is spun, i.e. low airspeed -> coarse pitch, high airspeed -> low pitch. Older, Walter-engined Zlin aircraft have the same (or similar) system.

S’funny.

Only a week or so ago I was discussing with some folks from WIX ‘aircraft that you only ever see at airshows and are damn@d if you kno what they are first time you see um’. P-2 was mine. Famous as ‘the aeroplane in Indiana Jones’.

I’m not an expert, but I think the finned unit is standard on Argus powerplants (another reason the P-2 get’s parts as a German a/c) and is a constant speed unit for the prop – or in non-tech speak, something to do with how the prop works by being spun by the airflow. Over to any resident engineers for a safer answer!

Cheers / salut

Could anyone please explain what the grooved spinner on the front of the propeller boss on the Pilatus does please?

I think all the P2’s have that undercarriage!

Blimey, that was quick!! Two mins.

Many thanks Stewart1a
