Abstract

This Report describes the results of wind tunnel tests on a 1/4th scale model of the Curtiss-Wright XP-55 Airplane. The experiments were made in the closed working section of the 10-foot wind tunnel of the GALCIT (Guggenheim Aeronautics Laboratory at the California Institute of Technology). The tests were made at a wind speed of approximately 150 m.p.h. (dynamic pressure 25 gm/cm^2), corresponding to Reynolds Number based on mean wing chord of about 1,670,000. The critical Reynolds Number at which a 15 cm. sphere has a drag coefficient of 0.3 is about 325,000, indicating a stream with rather low turbulences. The model was lacquered and rubbed down to a fairly high polish.
