Airscrews as Landing Brakes: I. The Realization of the Airscrew Landing‐Brake

Abstract

SINCE the first successful flight tests were made with the Escher Wyss airscrew some years ago, this type has been distinguished in this sphere by several fundamental innovations . From the beginning a very high speed of adjustment of approximately 8 deg./sec. was attained in normal operation as an automatic, constant‐speed airscrew. This property and the wide range of speed control between 100 per cent and approximately 40 per cent of the rated r.p.m. made it possible completely to release the pilot from control of the airscrew. Thus the problem of the automatic airscrew was finally solved (Fig. 1). That this solution was satisfactory has been proved by many years' service under the most stringent conditions in the Swiss Air Force.
