Abstract

607,924. Helicopters. POELVOORDE, P. J. VAN. April 27, 1946, No. 12745. [Class 4] A helicopter comprises a supporting and propelling unit 1 consisting of an engine and a propeller with blades rigid with the hub (or a pair of co-axial contra - rotating propellers) and universally mounted on the fuselage 2 to ensure the stability of the machine and to enable the propeller to be tilted forwardly to furnish a propulsive force. The universal mounting comprises a longitudinally disposed journal 7 beneath a transversely disposed journal 6. Fig. 5 shows an aircraft provided with a supporting and propelling unit 17, including a jet motor, at the end of each of a pair of wings 9, the units being in line with the centre of gravity of the machine. A number of such propelling units may be mounted at intervals along the fuselage. The propeller or propellers may be by worm gearing. Specifications 365,030, 437,447, 441,445, 493,439 and 534,864 are referred to.
