Pitch Control Margin at High Angle of Attack-Quantitative Requirements (Flight Test Correlation with Simulation Predictions)
Abstract
Aircraft designs that employ relaxed static stability (RSS) have the following problem: reduced pitching moments associated with RSS at high angle of attack (AOA) require a minimum pitch recovery moment or margin to guarantee a safe return from high AOA maneuvers at the most aft center of gravity (CG) encountered during a mission. Recent incidents and mishaps on Class IV aircraft have demonstrated a need for establishing quantitative longitudinal high AOA pitch control margin design guidelines for future aircraft. The Naval Air Warfare Center - Aircraft Division (NAWC-AD) is currently supporting an effort in conjunction with NASA Langley Research Center (NASA LARC) to quantify such requirements. NASA LaRC has conducted a series of extensive simulation evaluations to define these design guidelines.
