Estimating Instrumentation Data Acquired During Flight Test of a Helicopter using Predictor Models. Abstract: In this paper, we propose a hybrid system ...

I. INTRODUCTION. Helicopter design is a challenging process for engineers due to lots of rotating and dynamic systems that work syn- chronously.

In this paper, we propose a hybrid system consisting of decision trees and neural networks to calculate the measurement faults of sensor readings and to ...

The data of first flight used to estimate the model has been divided into two parts: the first part for estimation of the model and second part for validation ...

This paper examines the application of rotorcraft stability and control derivative estimation techniques for the purpose of formulating a reliable helicopter ...

during flight testing using telemetered frequency-sweep data ... costs both through revisions in flight-test methods and by using validated simulation models.

Sep 21, 2022 · The NRC and DRDC now use a framework and analysis approach that is intended to standardize SHOL testing with the use of modeling and simulation.

A comprehensive rotorcraft analysis model was used to predict blade aerodynamic and structural loads for comparison with flight test data.

Then, the accuracy and effectiveness of this empirical model was evaluated by comparing its predictions with the actual flight-test data gathered in Sortie 4.
