Flight Test Maneuvers for Closed Loop Lateral-Directional Modeling of the F-18High alpha Research Vehicle (HARV) Using Forebody Strakes

摘要

Flight test maneuvers are specified for the F-18 High Alpha Research Vehicle(HARV). The maneuvers were designed for closed loop parameter identification purposes, specifically for lateral linear model parameter estimation at 30, 45, and 60 degrees angle of attack, using the Actuated Nose Strakes for Enhanced Rolling (ANSER) control law in Strake (S) model and Strake/Thrust Vectoring (STV) mode. Each maneuver is to be realized by applying square wave inputs to specific pilot station controls using the On-Board Excitation System (OBES). Maneuver descriptions and complete specification of the time/amplitude points defining each input are included, along with plots of the input time histories.
