1. An altitude control system compressor assembly for an unmanned aerial vehicle comprising:
a compressor housing;
a motor housing disposed within a central cavity of the compressor housing;
a motor disposed within the motor housing;
an impeller, wherein the impeller overlies the motor housing such that the motor housing is positioned between the impeller and an inlet of the compressor housing; and
wherein an interior surface of the compressor housing extends around the central cavity, and wherein the motor housing is spaced apart from the interior surface of the compressor housing and provides an air flow conduit around the motor housing that dissipates heat from the motor.
