A two-piece nested air intake scoop for an engine cowl and methods of assembly and manufacture. The nested air intake scoop includes an air intake scoop lower duct and an air intake scoop upper duct coupled to the air intake scoop lower duct. The air intake scoop upper duct is reversibly nested within the air intake scoop lower duct. Reversibly nested includes at least two surfaces of the air intake scoop upper duct airtight mechanically connected to at least two surfaces of the air intake scoop lower duct.

An electric motor includes a stator having a first side and a second side, a first housing coupled to the first side of the stator, and a second housing coupled to the second side of the stator. A shaft of the electric motor has a first end and a second end. The shaft is rotatably supported by a first bearing and a second bearing. A propeller of the electric motor couples to the first end of the shaft. An inverter includes an inverter housing directly coupled to the first housing.

A fairing for an aircraft, comprises a wall element comprising an inner surface and an outer surface, wherein the outer surface is exposed to a free air flow outside the fairing, and at least one stiffener element attached to the inner surface of the wall element, to keep the fairing in shape under dynamic pressure loads. The fairing comprises at least one air inlet device comprising an inlet opening for a part of the free air flow outside the fairing to pass through the wall element and to enter the interior of the fairing. The air inlet device is at least partially integrated into the stiffener element, and the inlet opening of the air inlet device is formed in the stiffener element and extends into or through the stiffener element. The air inlet device and the stiffener element may be integrally formed as a single part, by 3D printing.
