ESDU Stability of Aircraft Segment
The ESDU Aerodynamics information contains a wide and ever-increasing range of data and methods applicable to the project design of aircraft, guided weapons, space rockets, etc. Data are given concerning general aerodynamics, including properties of the atmosphere; aerodynamics of airframe components, including the effect of power plant/airframe interactions for propeller-powered and jet aircraft; aerodynamics of the effect of surface imperfections on drag; aerodynamics of controls, flaps and leading-edge devices; aircraft stability, including derivative estimation; and aerodynamics of internal flow systems, including propulsion systems.
The Stability of Aircraft Segment focuses on:
- Longitudinal Stability - Derivatives due to Rate of Pitch
- Longitudinal Stability - Ground Effect, Downwash, Tandem Lifting Surfaces, Tailplane
- Pitch-Break Characteristics
- Lateral Stability - Derivatives due to Sideslip
