Maser’s Potential Rests on Further Work

Increasing pace of research in atomic amplifiers, spurred by their potentialities for improving radar, communications and countermeasures equipment performance, has already produced a variety of techniques and experimental devices.

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:

AIR TRANSPORT

Equipment, Routes Cripple Local Lines

Washington—Lack of modern flight equipment, strong route structures and present rate-of-return methods are cited by local service airlines as main stumbling blocks to subsidy-free operations. These are problems which face the industry as a whole.

Letters

Replies to Sayen Re the letter in the issue of July 29 by C. N. Sayen of ALPA (p. 118) concerning the Specht case. It might be well to discard emotion for a moment and examine this letter for what it says—not what it seems to say. Item: “. . . on the basis of brief and unverified newspaper reports . . .”

Guidance, Production Details Show Simplicity of Fireflash

London—Engineering and control details of Britain’s first fully operational Mach 2 guided missile system—the Fireflash—were revealed last week during a tour of a pilot production line at Fairey Aviation Co.’s Weapons Division in Heston.

AIR TRANSPORT

Airlines Edge Into Mass Market, Survey Shows; “Pay Later” Lags

New York—Transatlantic scheduled airlines have begun to penetrate the potential mass market of average-income passengers, a Port of New York Authority survey indicates. But transatlantic air travel still is largely for the well-heeled, the survey also shows.

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.
