Problems solved by technology

At present, there are many hybrid power systems suitable for vehicles, but there are few researches on hybrid power systems based on fixed-wing unmanned aerial vehicles, and because the driving forms of automobiles and aircrafts are different, the structure of vehicle-mounted hybrid power systems cannot be copied. The hybrid power system structure and propulsion mode of a fixed-wing unmanned aerial vehicle are very important

Abstract

The invention discloses a hybrid power system for a fixed-wing unmanned aerial vehicle and a propelling method. The system comprises a first propulsion motor, a first propeller, a first ISG motor, a first ISG motor clutch, a second propeller, a power controller, a battery pack, a transmission shaft, a third propeller, a second ISG motor clutch, a second ISG motor, a fourth propeller, a second propulsion motor, a first bevel pinion set, a transmission shaft bevel gear set, a second bevel pinion set, a main propeller, a main propeller clutch, a fuel engine and a transmission shaft clutch. The hybrid power system combines the advantages of fuel propulsion and pure electric propulsion, has multiple hybrid propulsion modes, and can effectively improve the whole voyage of the fixed-wing unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of hybrid power systems, and specifically refers to a hybrid power system and a propulsion method for a fixed-wing unmanned aerial vehicle. Background technique [0002] With the continuous development of new energy technology, more forms of power based on new energy have emerged, such as pure electric drive systems using electrochemical batteries, hybrid drive systems using internal combustion Fuel cell drive systems in the form of energy storage, among which the hybrid drive system is the most mature, which is further divided into series hybrid, parallel hybrid and hybrid hybrid. The above-mentioned new energy drive forms have been widely used and developed in vehicles in the past ten years, but as aircraft, especially fixed-wing unmanned aerial vehicles, internal combustion engine propulsion is still the main drive form, so new energy power is used as the propulsion form The fixed-wing unmanned aerial ve...
