Electric Drives

Taxiing Systems
Examining and evaluating
the electric drive system.

his article addresses the implementation
of electric taxiing without the use of main
engines by exploiting the electric propulsion of the landing gears. In a joint initiative, Honeywell Aerospace and Safran have
achieved substantial progress in developing an electric
green taxiing system (eTaxi). Significant analysis, design,
fabrication, and testing have already been completed and
culminated in a demonstration at the Paris Air Show (PAS)
in 2013. The eTaxi system has been installed on an A320
airplane that uses the auxiliary power unit (APU) to generate electric power to provide propulsion to two wheels of
the main landing gear. The primary advantages of such a
system are reduction of fuel consumption and audio
noise; reduction of carbon dioxide (CO2), carbon, and
nitrous emissions; reduced foreign-object-damage (FOD)
exposure to the engine; and the fast-turn time savings
achieved by the elimination of the ground tractor for pushback operation.
The electric drive system (EDS), which comprises an acto-dc converter, a wheel actuation control unit (WACU), and
a traction motor (TM), is the heart of the system. It performs
high-power conversion of electrical to mechanical energy. At
least one EDS is required to perform eTaxi functions. This
article focuses on the EDS and its components.
