Summary

[edit]
Description

Speaking of 'good at their job', have a look at the engine pylon behind the hot section- see the discolored bare metal that gets heated by the hot exhaust? Take a moment to admire how the bare metal runs. They put it where the heat will be greatest, shallower than the stream-line pylon-to-engine junction, at the front (right), but tipping up at the back end (left) where turbulence might bring hotter air higher on the pylon.

Cheap, painted, aluminum or composite, where they can live with it, bare, high-temp, metal, where it has to be. Lovely.

Engine manufacturers now design the nacelle but its not clear to me who owns the pylon, maybe its collective. Boeing wants the cheapest and most common interface, the engine builders want the cheapest and most effective installation for their product.
