Abstract

The design of the D.558 Skystreak in 1944 involved a full monocoque magnesium fuselage and there was a fear that a high‐temperature jet exhaust impinging on the structure might be unsafe. Tests in fact showed that magnesium due to its higher thermal diffusivity was safer than aluminium. Testing techniques for elevated temperature structures encompass a new field and as the methods of performing the tests have not become standardized, a wide variety of methods are being tried. A description of tests using the various methods tried by the authors of this paper are presented together with the reasons why the particular methods were chosen. Methods include a bank of furnace‐type gas burners, resistance heating techniques, heat blankets, lamp radiation and the Andersometer. Solar furnaces, shock tunnels, magnetohydrodynamic devices, plasma jets, etc., can be ruled out as the dimensions of the test article would be far too limited. Induction heating closely approximates the conditions encountered during aerodynamic heating, but cost and bulk of apparatus become a serious problem.
