Estimation of change in time of flight of unmanned flying vehicle with electrical engine

For effective operation of an unmanned flying vehicle, it is necessary to ensure as large time and range of its flight as possible. The extension of the flight time and hence the flight range can be achieved by increasing the fuel capacity. However this leads to an increase in the vehicle mass and hence to a reduction in the flight range. The application of electrical engines onboard the unmanned flying vehicle will require the onboard accommodation of accumulator batteries having a substantial mass. Meanwhile, the vehicle has large-area lifting surfaces (wings), on which photoelectric converters for feeding the engine can be arranged; this will enable the mass of accumulator batteries to be reduced substantially. A problem is considered regarding the extension of the flight range and time of the unmannedflying vehicle with electrical engine. The power supply of the electrical engine is provided from the accumulator batteries and photoelectric converters mounted on the vehicle wings. As a result of the investigation, it is obtained that the flight range increases by 4% with maintaining the vehicle maneuverability.
