Drag Measurement at Transonic Speeds on a Freely Falling Body

Direct measurements have been made of the drag of a special test body and its stabilizing tail surfaces throughout free drops from high altitudes. The data obtained have been used to establish the relation between the drag coefficient and the Mach number for the body and for the tail surfaces over a range of Mach numbers from 0.85 to 1.15. For bodies of the form tested, the drag per square foot of frontal area increased abruptly from about 3 percent of atmospheric pressure at a Mach number of 0.95 to 17 percent of atmospheric pressure at a Mach number of 1.00, then linearly with Mach number to 28 percent of atmospheric pressure at a Mach number of approximately 1.15. Some doubt exists as to the applicability of the tail drag results to the estimation of wing drag at transonic speeds because of the possibility of appreciable interference effects between the vertical and the horizontal surfaces and between the body and the tail surfaces. Insofar as they are applicable, the tail drag results indicated that with symmetrical 6-percent-thick area may be expected to increase abruptly from 4 percent of atmospheric pressure at a Mach number of 0.88 to 36 percent of atmospheric pressure at a Mach number of 1.00, then linearly with Mach number to approximately 50 percent of atmospheric pressure at a Mach number of 1.15.

Photographic Observations of Blade Motion of the YG-1B Autogiro Equipped with Tapered Rotor Blades

This report presents the results of photographic observations in flight of the flapping, the motion about the vertical pin, and the dynamic twist of a new type tapered rotor blade on the Kellett YG-1B autogiro. The blades, which were designed by the Kellett Autogiro Corporation, made use of the NACA 230 series airfoil section, for the purpose of eliminating undesirable dynamic blade twist present in the original blades. The results reported herein show that in actual operation the new blades very closely approach the desired condition of no dynamic twist.

A Flight Determination of the Moments of the YG-1B Tapered Blade Rotor about the Hub Trunnions

At the request of the Materiel Division, Wright Field, the National Advisory Committee for Aeronautics is conducting a program of flight tests on a Kellett YG-1B autogiro equipped with a new type of rotor blade. The new blades are tapered in both plan form. and thickness and are designed to avoid periodic blade twist. One phase of the investigation, involving determination of the moments of the resultant rotor force about the trunnions on which the hub is pivoted for control, has been completed. The results obtained are reported herein.
