A turbine connector in an engine exhaust manifold includes a turbine foot attached to incoming exhaust conduits. The turbine foot has an outer perimetric edge defining a trapezoidal shape, and inner perimetric edges forming exhaust outlets from the incoming exhaust conduits. The inner perimetric edges have varied perimetric curvatures largest in finite curvature size upon a web extending between the exhaust outlets, and together forming an hourglass web profile in a turbine-mounting plane defined by the turbine foot.

A gas turbine engine is provided having: a turbomachine; a fan section having a fan rotatable by the turbomachine; a nacelle enclosing the fan; and an engine controller positioned within the nacelle. The nacelle defines an inner surface radius (r) along the radial direction inward of the engine controller, wherein the engine controller defines a radial height (Δr) along the radial direction, a total volume (V), and a normalized radius (r′). The normalized radius (r′) is a ratio of the inner surface radius (r) to the total volume (V) to cube root, and wherein these parameters are related by the following equation: $0.1{\left(r^{\prime }\right)}^{-1}<\frac{\Delta r}{r}<{K\left(r^{\prime }\right)}^{-4/3},$
wherein the normalized radius (r′) is between 1.25 and 8 and K is equal to 40%, or the normalized radius (r′) is between 2.75 and 4.5 and K is equal to 65%.
