This paper deals with the co-design of a Network Control System (NCS) and its diagnosis. Residuals are shown to be affected by network packet losses. A new indicator, sensitive to packet losses is proposed and thus changes in the residuals due to faults or to packet losses can be differentiated. Results are exemplified through the simulation of a 4-rotor helicopter using the Matlab/Simulink sta...

The paper presents the experimental investigation of aerodynamic interaction between a helicopter model and ship with simplified geometry. In first phase experiment, series wind tunnel tests were carried out in order to study flow features on flight deck for several conditions, without presence helicopter. Pressure measurements Particle Image Velocimetry surveys performed assess effect velocity...

This paper studies a flight load test method for helicopter blade, including the structural force of strain gauge bridge modification, calibration and establishment equation in typical maneuvers. First, blade structure was analyzed gauges were pasted profile which considered to be important positions analysis safe helicopter. Second, Load equations obtained by ground test, would used convert ti...
