Detection of Airborne Beryllium Dust : Monthly Report Covering the Period from May1 to June 1, 1955

Description: During this period a prototype gamma ray detection system was assembled and data was obtained on samples of beryllium salts on filter paper under a variety of conditions. Ordinarily either a scaler-register combination or the CRM-recorder combination would be sufficient for obtaining data. Both units have been used here in order to utilize the particular advantages of each system. The scaler-register unit was employed for obtaining precise data over short intervals while the CRM-recorder was us… more

Low Speed Wind Tunnel Tests of Several Airfoil Sections Through 360 ° Angle of Attack

Description: A series of two-dimensional airfoils were run through a complete 360 ° angle of attack range to determine their low-speed force characteristics. The airfoils were chosen in an attempt to vary as many parameters (such as thickness, camber, thickness distribution, etc.) as possible with the limited number of shapes that time permitted. All airfoils tested had lift curves with two distinct stalls and quite similar drag curves between 0 ° and 90 ° angle of attack. The highly cambered sections devel… more
