IRN: AP19679602 “Development of a tethered unified dual-use multicopter platform with an inverter with increased frequency switching and high coefficient voltage conversion"
The goals of the project are to develop technical documentation and an experimental sample of a dual-purpose tethered multicopter platform with an inverter with increased frequency switching and a high voltage down conversion ratio.
Relevance of the project: The purpose of this research project is the growing importance of unmanned aerial vehicles (UAVs) in various fields, from civil to military. The current disadvantage of limited flight time of autonomous UAVs is driving the development of tethered high-altitude unmanned platforms (HAUPs). These platforms can provide virtually unlimited flight time, making them important for a wide range of missions, including telecommunications, disaster prevention, fire control, video surveillance, life rescue and military operations.
The topic is also relevant due to the current difficulties in transmitting energy to power UAVs via wireless methods, as well as the disadvantages associated with short flight duration and dependence on weather conditions. Tethered high-altitude unmanned platforms represent a promising solution for extending flight time.
The application of PVBPs in various fields such as telecommunications, emergency situations, environmental monitoring and military operations reflects their versatility and wide range of possible applications. Work on energy transfer for tethered UAVs is already beginning to appear on the world market, which emphasizes the relevance and promise of the topic.
The proposed tasks for creating a simulation model of the functioning of inverters for energy transmission and using the simulation results to determine the technical characteristics of energy inversion systems are new and have no analogues among the works reviewed, which makes this topic important for the development of unmanned technologies.
