Flight test data cycle map optimisation
Flight testing of aircraft in which new design concepts, problems, and deficiencies are examined, involves the collection of a large quantity of data or test parameters allocated onto blocks within a telemetry frame or Data Cycle Map (DCM). Individual parameters are sampled at different rates and may vary in both their word length and the number of words used to represent them. During a flight ...

متن کاملNeural Network Applications in Advanced Aircraft Flight Control System, a Hybrid System, a Flight Test Demonstration
Modern exploration missions require modern control systems that can handle catastrophic changes in behavior, compensate for slow deterioration in sustained operations, and support fast system identification. The dynamics and control of new vehicles remains a significant technical challenge. Neural network based adaptive controllers have these capabilities, but they can only be used safely if pr...
متن کاملHelicopter Rotor Airloads Prediction Using CFD and Flight Test Measurement in Hover Flight
An implicit unsteady upwind solver including a mesh motion approach was applied to simulate a helicopter including body, main rotor and tail rotor in hover flight. The discretization was based on a second order finite volume approach with fluxes given by the Roeand#39;s scheme. Discretization of Geometric Conservation Laws (GCL) was devised in such a way that the three-dimensional flows on arbi...
متن کاملValidating Uncertain Aircraft Simulation Models Using Flight Test Data
Reliability validation of safety-critical flight control systems requires accurate simulation models of aircraft. This paper proposes a simple approach to validate such models efficiently using flight data. A statistical model validation analysis is shown to be equivalent to a robust control analysis for simple linear systems. The analysis is extended to nonlinear systems in conjunction with Mo...
