The study is devoted to the problem of saving limited energy resources of unmanned vehicles (UAVs). Regardless of the size and weight of the UAV, its electronic-optical system consumes from 7 to 20 % of the battery's charge. Author proposes the method for the UAV clusters formation with wireless unplug of non-priority devices from the power supply on board the slave drones. The algorithm for alternately connecting to the power supply of similar devices on board various UAVs of one cluster has developed. To non-priority devices can be attributed digital cameras, meteorological sensors, etc., embedded to drones that fly from each other at a distance commensurate with the GPS coordinates’ error. In this case it is enough if the monitoring functions will only perform devices on the Master drone of cluster. Devices assigned to non-priority ones are unplugged by a signal via the Bluetooth module. After the task is completed by the Master UAV of the cluster or when removing the Slave UAV from the Master drone, Master UAV sends the signal to connect the non-priority devices to the battery on board Slave drones. Considering that the 4K digital camera consumes about 11.2 % of the UAV battery charge (for the entire flight time), it can be argued that due to the use of the created method, it is expected that the energy consumption will be reduced and the flight time of the UAV will be increased. It has been proven that certain progress in saving limited energy resources of a UAV can be achieved by direct interaction between the computer components of the Master and Slave UAVs. In this case the external commands of their owner (the ground dispatch center) are not required. A multi-scale modeling was performed on the Arduino platform. It has confirmed the operability of the devised method. Subsequently, the proposed method can be improved by implementing a remote interaction between drones, which are at a distance that exceeds the technical capabilities of the direct communication of the UAV modules within a flock.
