Field of Flow About a Jet and Effect of Jets on Stability of Jet-Propelled Airplanes
A theoretical investigation was conducted on jet-induced flow deviation. Analysis is given of flow inclination induced outside cold and hot jets and jet deflection caused by angle of attack. Applications to computation of effects of jet on longitudinal stability and trim are explained. Effect of jet temperature on flow inclination was found small when thrust coefficient is used as criterion for similitude. The average jet-induced downwash over tail plane was obtained geometrically.

Internal and external aerodynamics of ducted bodies at supersonic speeds
Report presenting a method for calculating the lift, moment, and pressure drag of slender open-nose bodies of revolution at supersonic speeds. An application of the method to a typical ramjet fuselage is shown to give excellent agreement with available experimental data.

A method for the determination of air infiltration rates in airplane cabins
From Summary: "A method for the experimental determination of the rate of infiltration of air into aircraft cabins during flight has been developed and tested. This method consists of releasing a quantity of gas in the cabin and calculating the infiltration rate from the measured rate of change of the gas concentration. The results of the flight tests indicate that after the infiltration rate is established at one altitude and airspeed, the infiltration rates at other altitudes and airspeeds can be calculated."

Numerical procedures for the calculation of the stresses in monocoques 3: calculation of the bending moments in fuselage frames
"This report deals with the calculation of the bending moments in and the distortions of fuselage rings upon which known concentrated and distributed loads are acting. In the procedure suggested, the ring is divided into a number of beams each having a constant radius of curvature. The forces and moments caused in the end sections of the beams by individual unit displacements of the end sections are listed in a table designated as the operations table in conformity with Southwell's nomenclature. The operations table and the external loads are equivalent to a set of linear equations" (p. 1).

Numerical procedures for the calculation of the stresses in monocoques 4: influence coefficients of curved bars for distortions in their own plane
"Formulas for the calculation of influence coefficients of curved beams of constant radius of curvature are presented corresponding to displacements in the plane of curvature. Moreover, numerical values are given in tabular and graphic form for a limited number of values of the parameter involved" (p. 1).

Preliminary Wind-Tunnel Investigation at Low Speed of Stability and Control Characteristics of Swept Back Wings
Note presenting tests conducted on untapered constant-span wings of 0, 30, 45, and 60 degrees sweepback. The purpose of the tests was to investigate the effect of sweepback on stability and control characteristics. The data showed large changes in longitudinal stability at moderate lift coefficients for the 45 and 60 degree sweptback wings.

Quantitative Treatment of the Creep of Metals by Dislocation and Rate-Process Theories
Note presenting an equation for the steady-state rate of creep, which has been derived by applying the theory of dislocations to the creep of pure metals. The form of this equation is in good agreement with empirical equations describing creep rates. A discussion of the way the theory can be applied to alloys, in particular heat-resisting alloys, is also provided.

Structural hinge-moment increments caused by hinge-axis distortion
Report presenting an investigation of elevators with three hinges to evaluate the structural hinge-moment increments resulting from changing the elevator angle when the hinge axis is distorted under load. The analytical results are compared to test data obtained for a full-scale semispan fighter-type horizontal tail surface in the 16-foot high-speed tunnel.
