Abstract
A propeller or propeller drive, the propeller being carried by a support shaft (3) which projects from the body (53) of the missile or vehicle and about which the propeller rotates, the drive unit for the propeller being situated in front of the propeller (23) in the propulsion direction or in the propeller spinner (1). According to the invention it is provided that the drive unit has at least one gas turbine (55), optionally a multiple-stage gas turbine, which is secured to the drive shaft and which drives it or jointly rotates with it, and that the drive shaft (6) is traversed by the support shaft (3) or is mounted thereon in a rotating manner and drives the propeller (23), optionally by way of a gear mechanism (14) situated between the turbine (55) and the propeller (23).
Claims30
A propeller drive for aircraft or watercraft comprising a propeller, a propeller spinner located forward of the propeller in a propulsion direction of the aircraft or watercraft, a support shaft carrying the propeller, projecting from a body of the aircraft or watercraft and formed by a hollow shaft about which the propeller rotates, a drive unit for the propeller being situated in front of the propeller in the propulsion direction of the aircraft or the watercraft, and a drive shaft mounting at least one gas turbine which drives the propeller via a gear train arranged between the at least one gas turbine and the propeller, wherein the drive shaft extends through and is rotatable relative to the support shaft, and wherein the drive unit for the propeller comprises the at least one gas turbine and is arranged within the propeller spinner.
A propeller drive for aircraft or watercraft comprising a propeller, a propeller spinner, a support shaft carrying the propeller and about which the propeller rotates, and projecting from a body of the aircraft or watercraft a drive unit for the propeller arranged in the propeller spinner, the drive unit including a compressor, a combustor and a rotatable turbine being situated in front of the propeller in the propulsion direction of the aircraft or the watercraft, and a drive shaft extending along and being rotatable relative to the support shaft mounting the turbine for rotatably driving the propeller via a gear train arranged between the turbine and the propeller.
A propeller drive for aircraft or watercraft comprising:
- a propeller for moving the aircraft or watercraft in a propulsion direction,
- a spinner defining a spinner housing located in front of the propeller in the propulsion direction,
- a stationary support shaft extending from the aircraft or watercraft in the propulsion direction past the propeller into the spinner housing, and
- a drive unit carried on the support shaft for rotating the propeller via a drive shaft that is rotatable relative to the support shaft and including a gas turbine having a rotor and a gear train, the rotor and the gear train being coupled to the drive shaft for rotating the propeller relative to the support shaft, the gas turbine and the gear train being located forward of the propeller in the propulsion direction and inside the spinner housing.
