Summary:

Lack of equipment suitable for measuring airplane propellers at flying fields and storage depots prevents the accumulation of reliable information on the effect of storage and service on the warping and change of blade angles in propellers. Such information would be of much value in perfecting specifications for manufacture and storage, and it is thought that a single instrument for this purpose would be appreciated.
