THE Liberator is one of the most distinctive four‐engined aeroplanes yet built. It has been designed round the Davis aerofoil, which was patented in the United States some years ago. This aerofoil does not appear to be unduly thin, although designed for high‐speed operation, but is claimed to provide an almost perfect co‐ordination of the airflow across upper and lower surfaces. The main plane of the Liberator is of exceedingly high aspect ratio, greater even than that of the Vickers geodetic aeroplanes, so that some special structural design must have been evolved. Extensive Fowler flaps are fitted, but it is not certain if the built‐in slots have been retained on the British version.
