Abstract

June, 1941 A I R C R A F T E N G I N E E R I N G 165 H E Liberator is one of the most distinc­ tive four-engined aeroplanes yet built. I t has been designed round the Davis aerofoil, which was patente d in th e 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 New R. A. F. Types 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 VI it is not certain if the built-in slots have been retained on the British version. The layout of the aeroplane is very neat. The deep fuselage and swept-up tail are dis­ tinctive characteristics. The tail of the fuselage looks large enough for the fitting of a British power-operated turret. The nose of the fuse­ lage is shorter than is usually the case with a The American tricycle undercarriage. The large span, com­ paratively short fuselage and large " end-plate " fins are very distinctive recognition features.
