KH-25 

The Kh-25 is a low wing-loading unmanned aerial vehicle (UAV) designed for efficiency, versatility, and experimental use. It features a wingspan of 2 meters and has a total weight of approximately 1200 grams, making it lightweight and well-suited for stable and energy-efficient flight. The low wing loading contributes to improved lift characteristics, allowing for longer flight durations, smoother handling, and better performance at lower speeds.

The UAV is powered by an economical propulsion system that is carefully selected to balance energy consumption and performance. Despite its efficiency-focused design, the Kh-25 achieves an excellent thrust-to-weight ratio, enabling responsive maneuverability and reliable climb performance. This combination of efficiency and power makes it ideal for extended missions and repeated testing cycles.

Constructed primarily from foam board, the airframe is both lightweight and cost-effective, while still providing sufficient structural strength and ease of repair. This choice of material also allows for rapid prototyping, modifications, and upgrades, which are essential for experimental platforms.

The Kh-25 is designed to function as a flying laboratory, carrying a range of onboard instruments and systems for research and development purposes. It is equipped with a Doppler-effect radar system, which can be used for motion detection, velocity measurement, and environmental sensing. In addition, the UAV supports multiple onboard sensors, which may include altitude, speed, temperature, and other environmental or navigation-related measurements. These systems enable the Kh-25 to be used in a wide variety of testing scenarios, including sensor validation, flight dynamics research, and data collection missions.

Overall, the Kh-25 represents a flexible and capable experimental UAV platform, combining lightweight construction, efficient propulsion, and advanced sensing capabilities to support innovation and exploration in unmanned aviation
