Abstract
Contactless power and data transfer is developed as an alternative to traditional slip rings with electrical connections. The contactless data transfer is power efficient, high bandwidth, reliable (because no or limited wear) and with low noise through an innovative near-field transmission of electrical waves. The technology does not need the modulation of radio waves applied for far-field transmission. Transformer technology is applied for the power transfer. The transfer technology is implemented in a module for in-flight application on a tilt rotor aircraft. A light-weight module is developed for installation in the hub of the proprotors. Additional to the data and power transfer a contactless optical sensor is integrated in the module for angular position measurement.
The development is both for integration in the aircraft avionics, e.g. measuring the flapping angle of the rotor blades and for enabling the transfer of power and data to Flight Test Instrumentation installed in the hub and on the rotor.
The power circuitry is developed in cooperation with DDC limited, partner in the Constance project and will be applied on the Leonardo Next Generation Civil Tiltrotor (NGCT) - Technology Demonstrator (TD), Leonardo being the topic leader for the project.
Constance will enable a safe and highly reliable link to the avionics and the Flight Test Instrumentation on the rotor.
