French Impress with New Jet Engines

Paris—Postwar French development in engines closely parallels the situation with regard to aircraft. The long years of research and prototyping seem ready to pay off in production. That is the feeling of foreign observers at the 21st international Salon de l’Aeronautique at the Le Bourget Aerodrome.

Leduc 0.21 Puts Ramjet in Spotlight

Next step in the development of this series is the 0.22, a sweptwing interceptor powered by a single Snecma Atar turbojet in the center of the hollow fuselage, surrounded by the concentric rings of ramjet burners. For Leduc, this will be a high point in an almost single-handed effort to make the ramjet a practical airplane powerplant instead of a scientific curiosity.

New Power Packages for Missiles

A new line of guided missile accessories is in pilot or prototype production in the shops of a newcomer in the field—American Machine & Foundry Co.’s Turbo Engineering department. The organization was set up by AMF to specialize in research and development of compact, high-output combustion devices, hot air turbomachinery and other equipment related to guided missile accessory power supplies.

Kidding the Public on Russian Airpower

The latest Russian air show over Moscow (see page 13) is the second formal display of five new types of long range jet bombers and high speed jet fighters in a few months. This air show in honor of Red Air Force Day was held at Tushino Airport near Moscow in an atmosphere not far removed from the great Western airpower exhibits at Le Bourget, Farnborough and our own traveling National Aircraft Show to be held this year at Philadelphia.

‘Cone of Confusion’ The writer has read with much interest the informative article by Commander H. H. Ward III published in your issue of May 30th (“Phase Shift Cleans Up ADF ‘Confusion’,” p. 73). His suggestions for cleaning up the so-called “cone of confusion” in ADFs are timely and helpful.
