Effect of unequal air-flow distribution from twin inlet ducts on performance of an axial-flow turbojet engine
Report presenting an investigation in the NACA altitude test chamber to determine the effect of inlet-air-flow distortion on the performance of an axial-flow turbojet engine with simulated twin inlet ducts. Results regarding the pressure and temperature profiles, component performance, overall engine performance, and operational comments are provided.

Theoretical Investigation Based on Experimental Frequency-Response Measurements of an Automatic Altitude Control in Combination With Supersonic Missile Configuration
Report presenting an analysis of an investigation of a simple altitude control based on static-pressure and rate-of-climb sensing is combined with a supersonic missile as a servomechanism to yield the closed-loop behavior of the entire system. The control system was found to function successfully at a low-altitude missile of the boost-guide type and would likely perform well at high altitude.

A method for increasing the effectiveness of stabilizing surfaces at high supersonic Mach numbers
Report presenting the use of wedge-shaped airfoil sections to obtain large increases in lift-curve slope at low angles of attack at high supersonic Mach numbers. The use of such sections on the tail surfaces operating at low angles of attack on airplanes or missiles traveling at these speeds can greatly decrease the stabilizing-surface area required.

Investigation of a high-temperature single-stage turbine suitable for air cooling and turbine stator adjustment 2: performance of vortex turbine at various stator settings
Report presenting a consideration of a mode of engine operation that requires operational flexibility of the turbine, which requires that the turbine stator and exhaust nozzle area are adjusted to maintain a fixed compressor operating point. Results regarding turbine performance and comparison of predicted and experimental turbine performance are provided.
