F-18 High alpha Research Vehicle (HARV) Parameter Identification Flight TestManeuvers for Optimal Input Design Validation and Lateral Control Effectiveness

摘要

Flight test maneuvers are specified for the F-18 High Alpha Research Vehicle(HARV). The maneuvers were designed for open loop parameter identification purposes, specifically for optimal input design validation at 5 degrees angle of attack, identification of individual strake effectiveness at 40 and 50 degrees angle of attack, and study of lateral dynamics and lateral control effectiveness at 40 and 50 degrees angle of attack. Each maneuver is to be realized by applying square wave inputs to specific control effectors using the On-Board Excitation System (OBES). Maneuver descriptions and complete specifications of the time/amplitude points define each input are included, along with plots of the input time histories.
