The system has been installed on a #Bell429 demonstrator aircraft at Bell’s facility in Mirabel, Quebec, and began flight testing on May 23, 2019. Since then, the aircraft has completed about 25 flight hours and gradually expanding its flight envelope./Bell Flight

The Edat system is composed of four small fans within a tail rotor shroud in an offset two-by-two pattern.Each of the rotors contains four blades, and they are powered by four separate motors, with the electrical energy provided through generators driven by the turbine engines

Edat Offering immense benefits to vertical lift operations, the innovation redefines norms for aircraft noise output, safety and electrical distribution. The fans are controlled via fly-by-wire, but the remainder of the helicopter’s controls remain the traditional hydromechanical system.
