Case Study: Model Validation and Experiment Design for Helicopter Simulation Model Development and Applications

  • David J. Murray-Smith
Part of the Simulation Foundations, Methods and Applications book series (SFMA)


This case study brings together issues that are important in the testing and validation of physically-based nonlinear models of helicopters and other types of rotorcraft. The need for accurate and fully-tested models has been increasingly recognised during the past 30 years because of the introduction of active control technology in helicopters. The techniques emphasised within the case study are based on the system identification and parameter estimation approach and special consideration is given to questions of test input design. Compared with many other application areas in engineering, the problems of model validation are challenging for all forms of rotorcraft due to issues such as the inherent instability of the vehicles for some flight conditions (unless external feedback control is applied), major uncertainties in terms of some aspects of the aerodynamics of the vehicles and problems with experimental test records due to the short record lengths likely to be available and the high levels of noise for some measured variables.
