ABSTRACT:
In a propeller measuring device, moving means move a probe relative to the propeller to a plurality of reference positions indicative of positions on a desired propeller shape. The probe determines the deviation from reference position and a recorder records the deviation. In one embodiment, the measuring means measures only from the time the probe contacts the propeller being measured until the reference position, which is a given distance beyond the position on a desired shape, is reached.
