This configuration uses an ironless armature since the magnetic flux path crosses the air-gap and the windings in between the two cars to form a closed magnetic circuit with the permanent magnets. Table A1 in Appendix A presents the main characteristics of the actuator [8]. Since the cars ...
A common damper configuration is the so-called under-platform dry friction damper in the form of a small piece of metal device located underneath the blade platform and actuated by centrifugal force against the platform due to engine shaft rotation. Figure 1 shows a Dummy bladed disk for ...
