A method and device is provided for increasing the efficiency of jet drives by recuperating effective power from the propulsion flow. A ducted propeller in the propeller housing, driven by a driving engine via a drive shaft, conveys the fluid for the jet drive out of the interior Vi of a radial turbine . The fluid is accelerated axially and ejected backwards against the direction of travel. This creates thrust. Because the pressure in the interior of the turbine decreases, new fluid from the environment flows directly via the blades of the rotating radial turbine from the outside to the inside, thereby driving them. A guide apparatus is missing. The power of the radial turbine is transmitted via a transmission to the drive shaft of the propeller, which relieves the driving engine and increases the efficiency of the jet drive. The invention is particularly suitable for electric drives.
Method for increasing the efficiency of jet drives by recuperating effective power from the propulsion flow, characterized in that in the propeller housing (5) a ducted propeller (4), driven by a driving engine (9) via a drive shaft (1), conveys the fluid for the jet drive from the interior Vi of a radial turbine (6), in that the propeller (4) accelerates this fluid axially and ejects it backwards against the direction of travel, in that new fluid from the environment flows from the outside to the inside directly via the blades of the rotating radial turbine (6) without a guide apparatus and thereby drives said radial turbine (6), and in that the power of the radial turbine (6) is transmitted via a transmission (2) to the drive shaft (1) of the propeller (4), which relieves the driving engine (9).
Device for increasing the efficiency of jet drives by recuperating effective power from the propulsion flow, characterized in that in the propeller housing (5) it contains a ducted propeller (4), which is driven by a driving engine (9) via a drive shaft (1), and in that it contains a radial turbine (6) without a guide apparatus through which fluid from the environment flows, wherein the fluid firstly flows through the radial turbine (6) and then through the propeller (4), and in that the radial turbine (6) is connected to a transmission (2) by means of which its power can be transmitted to the drive shaft (1).
