Aerodynamic study of a wing-fuselage combination employing a wing swept back 63 degrees : effectiveness at supersonic speeds of a 30-percent chord, 50-percent semispan elevon as a lateral control device

Description: Report presenting the effectiveness of a 50-percent-semispan, constant-percent-chord elevon, and of upper-space spoilers as lateral control surfaces for a wing-fuselage combination with a wing swept back 63 degrees over a range of Mach numbers. For the elevon, results indicated that only about half of the predicted rolling-moment effectiveness was realized. The spoilers were found to be inferior to the elevons for lateral control because of a rapid loss of effectivness above an angle of attack … more

Methods for Connection to Revolving Thermocouples

Description: Memorandum presenting several new methods that have been designed for obtaining electrical connection to thermocouples that are revolving at high speeds. Two general types of pickup system are described with modifications for special installations. Both pickup systems have been proved to transmit an accurate signal from a revolving thermocouple to within 0.045 millivolt at contact sliding speeds up to 5400 feet per minute.

Theoretical Calculations on ZPR Experimentation: Part 2. The Calibration of the Single Central Cross Control Rod

Description: From Abstract: "The report is concerned with a theoretical analysis of the experiment known as the Calibration of the 3" Cross Control Rod. The experiment provided 29 points on a curve of reactivity (in hours per centimeter) versus depth of control rod insertion. An attempt to reproduce this curve theoretically has been quite successful."
