The monograph contains a conceptual analysis of the possibility to create the high-speed (up to 800 km/h) and maneuverable small-size jet-powered combat aircrafts with an engine thrust of 10–90 kgf and reduced radar and thermal signature of the aircraft. The classification of unmanned aerial systems (UAV/UAS) is considered, an analysis of the market for mini turbojet engines with a thrust of 10–90 kgf is given. Based on the statistical analysis, the weight, geometric and speed characteristics of the small UAV/UAS were assessed from the point of using the mini turbojet engines with a thrust of 10–90 kgf. The dynamic and altitude-speed characteristics of the basic UAV/UAS with a thrust of 20 kgf are presented. An analysis was carried out of the feasibility of using technologies to reduce radar and thermal signature in the design of small UAVs/UASs. A list of possible operational-tactical tasks for small UAVs/UASs with mini turbojet engines thrust of 10–90 kgf has been formulated. In conclusion, the prospects for the future development of small-size jet-powered UAVs/UASs are considered. All the data presented in the book are valid on January 1, 2023.

Unmanned Aerial Vehicle (UAV) propulsion technology is significantly related to the flight performance of UAVs, which has become one of the most important development directions of aviation. It should be noted that UAVs have three types of propulsion systems, namely the fuel, hybrid fuel-electric, and pure electric, respectively. This paper presents and discusses the classification, working principles, characteristics, and critical technologies of these three types of propulsion systems. It is helpful to establish the development framework of the UAV propulsion system and provide the essential information on electric propulsion UAVs. Additionally, future technologies and development, including the high-power density motors, converters, power supplies, are discussed for the electric propulsion UAVs. In the near future, the electric propulsion system would be widely used in UAVs. The high-power density system would become the development trend of electric UAVs. Thus, this review article provides comprehensive views and multiple comparisons of propulsion systems for UAVs.

Recently, unmanned aerial vehicles (UAVs), also known as drones, have gained widespread interest in civilian and military applications, which has led to the development of novel UAVs that can perform various operations. UAVs are aircraft that can fly without the need of a human pilot onboard, meaning they can fly either autonomously or be remotely piloted. They can be equipped with multiple sensors, including cameras, inertial measurement units (IMUs), LiDAR, and GPS, to collect and transmit data in real time. Due to the demand for UAVs in various applications such as precision agriculture, search and rescue, wireless communications, and surveillance, several types of UAVs have been invented with different specifications for their size, weight, range and endurance, engine type, and configuration. Because of this variety, the design process and analysis are based on the type of UAV, with the availability of several control techniques that could be used to improve the flight of the UAV in order to avoid obstacles and potential collisions, as well as find the shortest path to save the battery life with the support of optimization techniques. However, UAVs face several challenges in order to fly smoothly, including collision avoidance, battery life, and intruders. This review paper presents UAVs’ classification, control applications, and future directions in industry and research interest. For the design process, fabrication, and analysis, various control approaches are discussed in detail. Furthermore, the challenges for UAVs, including battery charging, collision avoidance, and security, are also presented and discussed.
