Experimental Evidence of Sustained Coupled Longitudinal and Lateral Oscillations From a Rocket-Propelled Model of a 35 Degree Swept Wing Airplane Configuration (open access)

Experimental Evidence of Sustained Coupled Longitudinal and Lateral Oscillations From a Rocket-Propelled Model of a 35 Degree Swept Wing Airplane Configuration

Memorandum presenting a rocket-propelled model of a representative 35 degree sweptback wing airplane design at high subsonic Mach numbers to investigate the possibility of the existence of coupled longitudinal and lateral motions. The data indicate the existence of sustained longitudinal motions of appreciable amplitude forced by lateral oscillations. The longitudinal motions had twice the frequency of the lateral oscillations and are shown to be the result of aerodynamic moments due to sideslip and inertial cross coupling.

Experimental investigation of effect of high-aspect-ratio rotor blades on performance of conservatively designed turbine (open access)

Experimental investigation of effect of high-aspect-ratio rotor blades on performance of conservatively designed turbine

"A considerable weight reduction in the turbine wheel of an aircraft gas turbine is attained through the use of high-aspect-ratio rotor blading. An experimental investigation was made to compare the performance of a turbine of conservative aerodynamic design having shrouded rotor blades with an aspect ratio of 4.48 with that obtained from both a shrouded and an unshrouded rotor design with aspect ratio of 2.24. The use of high-aspect-ratio rotor blades had a negligible effect on the turbine efficiency" (p. 1).

Measurement and Calculation of Blade Torsional Deflection of Three Supersonic-Type Propellers (open access)

Measurement and Calculation of Blade Torsional Deflection of Three Supersonic-Type Propellers

Report presenting an investigation to determine the blade torsional deflection of three supersonic-type propellers at various operating conditions. Blade-torsional deflection was found to produce appreciable results that can be predicted by theory with good accuracy. Results regarding the efficiency, thrust coefficient, and power coefficient are provided.

Reflection of Electrons by a Model Magnetic Mirror Machine (open access)

Reflection of Electrons by a Model Magnetic Mirror Machine

Abstract: A visualized electron beam has been reflected by a conventional magnetic mirror. Visualization of the beam path from the electron gun to and including the region of reflection was achieved by the "thread ray" technique of Wehnelt. The total current passing through a magnetic mirror has been measured as a function of the beam energy and angular momentum for Hâ‚‚ over a range of pressures from 0.5 to 5 microns.
