Correlation of Predicted and Free-Flight Responses Near Departure Conditions of a High Incidence Research Model,

Abstract

The mathematical model of aerodynamic forces and moments is described, based on results from various wind-tunnel experiments with the RAE High Incidence Research Model (HIRM). Simulations of the responses due to longitudinal and lateral control inputs at high angles of attack are compared with the responses measured on free-flight models of the configuration. It is shown that the main features of the flight behavior are reproduced, in particular such phenomena as roll-off, wing rock and nose slice.
