A4d Design Opposes Complexity Trend

El Segundo—Simplification and low-cost concept underlying the Douglas carrier-based A4D “midget” attack-bomber fits the philosophy behind economy measures now being projected for the aviation industry. Although established five years ago, this design approach for the A4D Skyhawk, smallest and lightest of U. S. jet combat planes, brings these advantages:

Gyron Fits Mach 3 Propulsion System

Compared with complex high compression ratio split compressor and variable stator engines optimum for current Mach 0.8-2 flight, de Havilland’s Gyron seems at first glance to be a backward step. However, the complete picture of the propulsion system into which de Havilland visualizes blending the basic Gyron illustrates how turbojets will tend to become second-fiddle to supersonic inlets and ramjet-like afterburners as jet aircraft approach Mach 3 speeds.
