High‐Power Engine Development: A Widely‐Disseminated German Survey of Progress in the Past Twenty Years Available to Purchase

SOME months ago a number of German aeronautical and military papers published an article in which some of the important problems of aero‐engine design, as seen from a German point of view, were surveyed. The author concluded his survey by stating that (1) the solution of these problems had enabled German aviation to recover the advantage which foreign aviation had gained between the end of the late war and the inauguration of the National Socialist regime; (2) these German achievements have greatly improved the performances of modern military machines all over the world.
