Implications of Recent Rotary Rig Results for Flight Prediction

摘要: Analysis of rotary balance data on a generic aircraft model revealed the nature flow mechanisms present in subscale experiments, which included existence support interference. Recent results F/A-18 confirmed threshold rotation rate and that nonlinear domain at elevated angles attack, alternatively deterministic or chaotic behavior will prevail, depending whether not magnitude initial exceeds value. This has important implications for flight mechanics predictions control system design as poststall maneuvering envelope often include hysteresis loop. Moreover, dynamic generated to date have been restricted this inner region, limited by rates, do provide any information about basic hysteretic behavior. Only comprehensive investigation steady-state interference, case F/A-18, can basis needed
