Effect of Wing Size and Amount of Indentation on Applicability of Transonic Area Rule to Swept-Wing Configurations
Memorandum presenting a systematic transonic zero-lift drag investigation utilizing a swept-wing configuration with three different ratios of wing to fuselage size utilizing a 6-inch helium gun. The experiments and comparisons with other results indicated that the reduction of pressure drag obtainable from partial indentation is approximately proportional to the amount of indentation employed up to a Mach number of 1.3. Results regarding the basic data, total drag, pressure drag, equivalent bodies, and special projections are provided.

Some Considerations Regarding the Application of the Supersonic Area Rule to the Design of Airplane Fuselages
Memorandum presenting certain considerations and techniques pertinent to the application of the supersonic area rule to the design of airplane fuselages. Some of the factors considered are an extension of the rule to account for the interference effects of the wing and tail on the general flow field for asymmetrical configurations, the determination of fuselage area developments which result in approximately the minimum wave drag, and the influence of wing parameters and design Mach number on the effectiveness of fuselage shaping.

Effect of Phosphate Coatings on Temperature of Metal Parts Exposed to Flame Environments
Note presenting an investigation of the effect of phosphate coatings on the temperature of metal specimens placed in a flame. Small cylindrical specimens of mild steel and S-816 alloy were placed in a natural-gas-air flame at specific temperatures. Special attention is given to the fact that temperature drop was noted in certain specimens and the potential reasons for this reaction are explored.

Comparison of several methods for obtaining the time response of linear systems to either a unit impulse or arbitrary input from frequency-response data
Report presenting a description and comparison of several methods of obtaining the time response of linear systems to either a unit impulse or an arbitrary input from frequency-response data. All of the methods give good accuracy when applied to a second-order system; the main difference is the required computing time.
