The relationship between elastic deformation and elastic vibration on dynamics (IMAGE)
Caption
- This schematic illustrates the intricate interconnections between different physical domains in aerospace vehicle guidance and control systems, demonstrating how thermal, structural, and aerodynamic effects interact throughout the vehicle's operation.
- The diagram reveals a sophisticated control system where real-time flight status data feeds into guidance & control laws, generating precise commands such as rudder deflection to maintain optimal trajectory and stability while accounting for varying flight conditions.
- The system must withstand extreme operational challenges, including intense aerodynamic heat during high-speed flight and fundamental structural strength limitations, while accounting for substantial airframe deformation and air-rudder deformation caused by combined thermal and mechanical loads.
- These interconnected factors create complex feedback loops that continuously modify the vehicle's aerodynamic properties and control effectiveness, necessitating advanced control approaches that simultaneously address coupled thermal, structural, and aerodynamic effects across the entire flight envelope.
