11 SEPTEMBER 1959 FLIGHT There are, of course, several systems for preventing explosions in fuel tanks struck by missile fragments. But most of them are complicated—and they can only be used once. So they're not very practical for very high-speed aircraft, where aerodynamic heating of the tank walls can produce explosive conditions many times in one sortie. Now B.O.A.E. have developed a new system for discouraging explosions. It consists of a simple converter containing liquid nitrogen. Nitrogen vapour is introduced into the tank pressurisation line... and keeps the atmosphere in the tank inert from take-off to touch down. For aircraft of 3,000 gallons fuel tankage, the whole system weighs less than 50 lb. It's all very simple. No electrical circuits. No detection units. No explosions. Can't think why someone hasn't thought of it before. w - British Oxygen Aro Equipment THE PINNACLES • HARLOW • ESSEX British Oxyoen Aro Equipment combines the resources of the British Oxygen group of companies and the Aro Equipment Corporation of Ohio and Is backed by the extensive facilities of the British Oxygen Research and Development Establishment at Morden.
