I June 30, 1938. Supplement to 648a TURCRAFT%*. ENGINEER Mo. 149. June 30, 1938. EXTRUSION of LIGHT ALLOYS An Industry Which Has Made Great Strides : Increasing Application in Aircraft IF one looks around among the types of military aircraftin service to-day it is found that nearly all the morerecent are of the thick-wing cantilever monoplane variety. When the need for high performance arose a few years ago, the biplane which had served us so well for many years was ruled out, partly by the fact that it was ex- tremely difficult to provide a retractable undercarriage without encroaching on the already limited fuselage space (the wings were, of course, too thin to house the retracted wheels). The thick-wing monoplane, particularly if the wing was set low on the fuselage, offered a fairly ready solution to the wheel-retraction problem, and the low-wing cantilever monoplane became the fashion. The aircraft industry was faced with two sets of problems: aerodynamic design and structural engineering solutions to carry the heavy loads. The former were con- cerned mostly with the elimination of interference drag at the junction of wing and fuselage, and with avoiding tail buffeting. Fillets in the angle between the two appeared to reduce both problems to reasonably small proportions.
