| Spinners The spinners on some Arado aircraft, e.g., the AR 96 and the AR 396, had some kind of expanding, flower-like front end. Does anyone know what these are or what their function was? |

| My guess it was to improve airflow around the cowling and into the engine for better cooling.

| From what Ive read on it they were used to regulate the variable pitch mechanism for the propellers but not sure exactly on how they work.

| The Spinner called Rippenhaube. On a Hamilton Constantspeed Propeller the energy for the pitch of the blades comes from the engine oilpressure. The ARGUS propellers take the energy for the pitch of the blades from the airstream at the Rippenhaube. It is a mechanical constantspeed propeller. |

| This is a scan from the manual of the ARGUS As 410 MA Motoranlage. It shows the parts of the ARGUS-Propeller. |
