Stealth ariframe design methodology for high altitude real-time reconnaissance drones

摘要

This apper presents the design philosophy behind the development of a Stealth Unmanned Air Vehicle (UAV) for real-time reconnaissance applications. The aspects of the threat analysis, the mission analysis and the Radar Cross Section (RCS) requirement definition leading to the design concept of the airframe, are introduced. The Electro Magnetic (EM) design requirements for low radar signature are derived and brought into context with the development of the composite airframe.
