Abstract

1317975 Jet nozzle on rotor blade VEREINIGTE FLUGTECHNISCHE WERKEFOKKER GmbH 7 July 1970 [8 July 1969 11 Sept 1969] 32986/70 Headings B7G and B7W The area of a nozzle 6 of a jet-propelled rotor blade 1 on a rotary wing aircraft is varied by means of a resilient element 8. This element is formed from a strip of metal and may be drawn by means of a cable 9 into a position such as that indicated in dotted lines, thereby reducing the cross-sectional area of the nozzle for increasing the velocity of the jet.
