Feasibility study of an induction motor rim drive for an aircraft boundary-layer-ingestion fan

Research output: Contribution to conferencePaper

Abstract

This paper presents a feasibility study for an induction motor
rim drive to power aircraft BLI fans. The design is developed
from a BLI-fan specification for traditional aircraft
architecture: the rotor is fastened to the rim of the blade
shroud, not to obstruct the fan duct and interfere with the airflow.
The main objective of this study is the identification of
achievable power density and efficiency levels with an
induction motor rim drive configuration considering the
structural requirements for the integrity of the rotor operating
with high tip speeds. The proposed 250 kW, 14,000 rpm
design example achieves an efficiency in excess of 97% with
an active mass around 20 kg.
