Elevated Temperature Properties of Titanium Carbide Base Ceramals Containing Nickel or Iron

Description: Elevated-temperature properties of titanium carbide base ceramals containing nickel or iron were determined in oxidation, modulus of rupture, tensile strength, and thermal-shock resistance. These materials followed the general growth law and exhibited two stages in oxidation. The following tensile strengths were found at 2000 degrees F: 13.3 weight percent nickel, 16, 150 pounds per square inch; 11.8 weight percent iron, 12,500 pounds per square inch; unalloyed titanium carbide, 16,450 pounds p… more

The static longitudinal characteristics at Mach numbers up to 0.95 of a triangular-wing canard model having a triangular control

Description: Report presenting the longitudinal stability and control of a canard model employing a triangular wing of aspect ratio 2 and a control surface of identical plan form at Mach numbers up to 0.95. The fixed control surface was effective in producing pitching moments at angles of incidence up to 10 degrees. Results regarding the static longitudinal characteristics, control-surface effectiveness, stability and effectiveness derivatives, and evaluation of the split flap effectiveness are provided.

Fundamental Flame Velocities of Pure Hydrocarbons 3: Extension of Tube Method of High Flame Velocities - Acetylene-Air Mixtures

Description: Memorandum presenting an extension of the tube method of measuring flame velocities to fundamental flame velocities of 141 centimeters per second. The extension was accomplished by reducing the flame-tube diameter from 25 to 12.5 millimeters. Results regarding the gas flow and spatial flame velocity, flame surface area, and fundamental flame velocity are provided.
