Abstract: Helicopter with tip-jet rotor drive comprising at least two rotor blades attached to a central shaft, where each rotor blade comprises means for guiding a fluid from a location close to said central shaft towards a tip of the rotor blade. At the area of said tip there is an outlet arranged so that by each of the rotor blades a jet stream is generated. The helicopter comprises a compressor for releasing compressed air. This compressor is co-axially arranged with respect to said central shaft above the rotor blades. The compressor is connected to the rotor blades to feed compressed air into the rotor blades. A piping system is provided for feeding fuel into the rotor blades. Each rotor blade comprises a combustion zone and means for bringing the fuel and compressed air together so that a combustion process is maintained which produces the jet streams.
