AI Technical Summary

Problems solved by technology

A single motor propulsion system may also not be able to meet the power demands required by the propulsion system in the most efficient manner
Using two or more motors in a propulsion system solves these problems but creates air management problems where the exhaust from one of these motors is sucked in by the other
Ingestion of exhaust gases by the motor may cause the motor to run at unacceptably high temperatures, subjecting the electrical components of the motor to high thermal conditions and may affect the life, performance and efficiency of the motor
This air management problem is exacerbated when one of these motors discharges exhaust towards or adjacent to the intake of the other motor

Abstract

A stacked motor assembly for an aircraft and the aircraft, the stacked motor assembly includes a front motor with an air outlet and a rear motor arranged behind the front motor, the rear motor has an air inlet. The stacked motor assembly includes an exhaust duct originating at the exhaust port of the front motor and at least partially disposed around the rear motor such that exhaust gas from the front motor bypasses the rear motor. The stacked motor assembly also includes an air intake duct terminating at the air intake of the rear motor and disposed at least partially around the front motor such that air intake from the rear motor bypasses the front motor.

Description

technical field [0001] The present disclosure relates generally to air management systems for aircraft motors, and more particularly to air management systems for stacked motor assemblies used to power aircraft propulsion systems. Background technique [0002] Electric motors may be used in aircraft as power sources for various functions, such as providing rotational energy in aircraft propulsion systems. Some electric motors utilize airflow to cool their internal electrical components, drawing ambient air into the motor and expelling warmed air out of the motor. In aircraft propulsion systems using only a single motor, the lack of a backup motor increases the likelihood of a fall or other catastrophic condition due to motor failure. A single motor propulsion system may also not be able to meet the power demands required by the propulsion system in the most efficient manner. The use of two or more motors in a propulsion system, while solving these problems, can cause air m...
