Abstract
A propulsion system suitable for use in aircrafts (for example propeller plane) is provided. The propulsion system includes at least one propeller hub, which is mountable to at least a portion of the aircraft and includes at least one rotatable propeller blade thereon, propeller blade which is foldable, at least one fuel nozzle which is provided on the propeller hub and used to spray fuel into the section where the propeller blades are folded.
Claims20
A propulsion system comprising a propeller, wherein the propeller is rear-mounted to an aircraft and propeller blades of the propeller are allowed to be folded backwards;
- and a fuel nozzle, wherein the fuel nozzle is allowed for spraying a fuel between the propeller blades in a closed position of the propeller blades;
- wherein by means of folding the propeller blades backwards, a high pressure area is created between the propeller blades and by means of spraying the fuel into the high pressure area and burning the fuel, the propeller blades does not lose propulsion properties at high speeds.
A propulsion system suitable for use in aircrafts comprising
- at least one propeller hub, wherein the at least one propeller hub is mountable to at least a portion of the aircraft and comprises at least one rotatable propeller blade the at least one propeller hub,
- the at least one rotatable propeller blade, wherein the at least one rotatable propeller blade is foldable,
- at least one fuel nozzle, wherein the at least one fuel nozzle is configured to spray the fuel into a section where the propeller blades are folded.
A method of increasing an aircraft speed for expanding an efficiency range of the aircraft speed and thrust depending on a speed in an aircraft, wherein the method comprises
- folding the propeller blade in case a thrust efficiency of the propellers decreases,
- spraying a fuel into a high-pressure area formed between the propeller blades when the propellers are in a folded position.
