Conceptual Design of High Altitude Pseudo-Satellite
Keywords:
High Altitude Pseudo-Satellites, UAVs, satellites, aerodynamic, power-to-weight ratioAbstract
In the context of modern security, which is characterized by complexity and rapid transformation, High Altitude Pseudo-Satellite: HAPS technology is regarded as a future-oriented solution capable of enhancing or replacing existing Unmanned Aerial Vehicles: UAVs and satellite systems. With applications in surveillance and reconnaissance, this research aims to develop a conceptual design approach for solar-powered HAPS, emphasizing simplicity and practical applicability under constraints related to energy, weight, and environmental conditions at altitudes 17 kilometers above sea level. The proposed design approach includes an analysis of the mass-energy balance, an assessment of solar energy potential within the climatic context of Thailand, and the estimation of aerodynamic parameters such as power-to-weight ratio and wing loading. The study presents a prototype aircraft with a total weight of 77 kilograms and a wingspan not exceeding 30 meters, capable of continuous operation for more than 24 hours for a minimum duration of one month. Furthermore, the system is equipped with real-time data transmission capabilities via ground-based communication networks.
