    Abstract: An aeronautical propulsion system includes a fan having a plurality of fan blades rotatable about a central axis and defining a fan pressure ratio, FPR. The propulsion system also includes an electric motor mechanically coupled to the fan for driving the fan, the electric motor including a number of poles, npoles, and defining a maximum power, P. The relationship between the fan pressure ratio, FPR, of the fan, the number of poles, npoles, of the electric motor, and the maximum power, P, of the electric motor is defined by an equation: n pole p = C 1 · e - 9.062 · FPR + C 2 · e - 1.2604 · FPR ; wherein C1 is a constant having a value between 22,000 and 52,000, wherein C2 is a constant having a value between 4.0 and 9.8, and wherein e is Euler's number.

    Abstract: A tubular array heat exchanger and a method of manufacturing the same are provided. The heat exchanger includes a plurality of helical tubes defining a primary diameter around the centerline to define interstitial voids between the plurality of tubes. The plurality of tubes defines an increased surface area compared to a single heat transfer tube having the same primary diameter, thereby resulting in improved heat transfer efficiency or a smaller footprint. In addition, the helically formed tubes and optional stiffening structures improve the structural resiliency of the heat exchanger to better absorb thermal expansion and contraction with improved modal response.

    Abstract: An electric machine includes a stator assembly including a first stator segment and a second stator segment, the first and second stator segments each including a plurality of laminations extending generally along a circumferential direction, each pair of adjacent laminations of the first and second stator segments defining a gap therebetween. The first and second stator segments are assembled together such that the laminations of the first stator segment are arranged at least partially in the gaps between the laminations of the second stator segment.

    Abstract: A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a housing defining a flow passageway having a plurality of heat exchange banks stacked therein. Each heat exchange bank includes a plurality of heat exchange tubes that form a lattice structure that extends from a first end proximate a central manifold outward along the radial direction toward a second end proximate an annular outer manifold. The central manifolds and the annular outer manifolds fluidly couple the heat exchange tubes of adjacent heat exchange banks in an alternating manner to form a serpentine flow path for a flow of heat exchange fluid.
