Aerodynamic Characteristics of Several 6-percent-thick Airfoils at Angles of Attack from 0 to 20 Degrees at High Subsonic Speeds by Bernard N. Daley Pdf

Two-dimensional tests of eight 6-percent-thick symmetrical airfoils of the supersonic and subsonic types were conducted in the Langley rectangular high-speed tunnel. The aerodynamic characteristics of each of the airfoils have been determined from the measured pressure data. These results showed that the lift-curve slope of each of the airfoils decreased rapidly to a positive value approaching zero at angles of attack near 9 degrees and roughly maintained this value up to the highest angle of attack tested.

Noise Survey of a 10-foot Four-blade Turbine-driven Propeller Under Static Condtions by Max C. Kurbjun Pdf

Theoretical calculations of the sound-pressure levels by the method of NACA TN 2968 predict accurately, for the 10-foot propeller investigated, the location of and the maximum levels to be expected for the overall noise and the first two propeller harmonics. The calculations do not predict accurately the location of the maximum sound-pressure levels ad the maximum calculated levels are 10 and 13 decibels lower than the msximm messured levels for the third and fourth harmonics, respectively.

Qualitative Simulator Study of Longitudinal Stick Forces and Displacements Desirable During Tracking by Stanley Faber Pdf

In this study in which an airplane simulator with one degree of freedom (pitch) was used, results were determined for three conditions of airplane dynamics. For an undamped natural frequency of 1/2 cps with a damping ratio of 0.18 and for an undamped natural frequency of 1 cps with a damping ratio of 0.11, moderate longitudinal stick forces and displacements were desired.
