Real-Time Parameter Identification

Metadata Updated: May 2, 2019

Armstrong researchers have implemented in the control room a technique for estimating in real time the aerodynamic parameters that describe the stability and control characteristics of an aircraft. Typically, aerodynamic modeling is performed on recorded data after test flights and then used in simulations. The drawback with this approach is that if the collected data are not complete or of high quality, additional and costly flight tests must be scheduled. In this innovative approach, Armstrong[HTML_REMOVED]s real-time parameter estimation automates the process and runs during flight, enabling researchers in the control room to evaluate and adjust flight maneuvers to ensure data quality. The technology increases the efficiency and productivity of flight tests, as researchers can determine during the tests if they have collected the data needed for specific modeling simulations.Work to date: The technology is currently being used in Armstrong control rooms to evaluate data collected during test flights as well as in-flight maneuvers.Looking ahead: Researchers are continuing to improve the system display and are working to refine the way results are presented. A capability to compare the estimated parameters to preflight-predicted values is being added, which will make it possible to evaluate the aerodynamic effects of aircraft modifications.Benefits Automates data collection: Estimates in real time the parameters for aircraft stability and controlImproves data quality: Enables adjustments during flight tests to ensure correct data acquisitionSaves time and resources: Decreases the duration and number of flight testsApplications Aerodynamic modeling
