Title:
AERODYNAMIC COEFFICIENT ESTIMATION DEVICE AND CONTROL SURFACE FAILURE/DAMAGE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/115164
Kind Code:
A1
Abstract:
The disclosed device can compute a high-reliability estimate of aerodynamic coefficients, allowing accurate detection of failure of or damage to control surfaces while reducing the burden on passengers. Said device is provided with: a control-angle command-signal generation means (5) that generates a control-angle command signal for estimating aerodynamic coefficients that indicate the aerodynamic characteristics of an airframe; a kinetic state quantity acquisition means (6) that acquires kinetic state quantities for the airframe, resulting from control surfaces provided on the airframe being driven on the basis of the control-angle command signal; a candidate-value computation means (7) that uses at least two different estimation methods to compute, from the kinetic state quantities, candidate values for estimating the aforementioned aerodynamic coefficients; and an aerodynamic coefficient estimate determination means (8) that determines aerodynamic coefficient estimates on the basis of the candidate values.
