Electronics progress report

Description: The Argonne National Laboratory model of the Vibrating Reed Electrometer was installed in the laboratory of Group 3 to detect the point at which electrodeposition of a radioactive element begins. As now set up, the Vibrating Reed Electrometer has a direct reading sensitivity of 10{sup {minus}12} amperes and this can be increased to 10{sup {minus}17} amperes by using it as a rate of charge instrument. During the past month the ionization chamber was designed and constructed and the complete syst… more

The Influence of Dimensional Modifications upon the Spin and Recovery Characteristics of a Tailless Airplane Model Having Its Wings Swept Forward 15 Degrees (Cornelius XFG-1)

Description: "An investigation has been conducted in the Langley 20-foot free- spinning tunnel scale model of the Cornelius XFG-1 glider, a tailless design having its wings swept forward 15 degrees. It was previously found to possess erratic spin and recovery characteristics, and tests were made to determine modifications which would lead to normal steady spins with consistently good recoveries. The results of the investigation indicated that modifications that aid not appreciably alter the basic design aid… more
