THEORETICAL INVESTIGATION OF DUCTED PROPELLER AERODYNAMICS VOLUME 4

Abstract

The performances of VTOL aircraft using ducted and free propellers are compared The comparison is based on existing light VTOL aircraft equipped with ducted propellers and on the same aircraft using free propellers computed for this purpose. The free propellers appear to provide better aircraft performance, especially higher flight speed. An appraisal and analysis of VTOL aircraft b sed on the existing VTOL testbeds forms the second part of this volume. Summaries of design particulars and performance re given in graphical and tabular form. The special purpose vehicles, such as the flying jeeps, aerial platforms and aerodynes, are treated as a separate group. Particular performance data of the various VTOL aircraft are collected in an appendix.
