NACELLES/PYLONS - DESCRIPTION AND OPERATION 1. General A. Two engines are installed on the airplane, one on each wing. (See figure 1.) Each engine is mounted at three points directly from the wing. The cowling and supporting structure of the engines is generally constructed of aluminum alloy. Steel, stainless steel or titanium is used in areas where high structural strength and fire or heat resistance is required. The engine-to-wing fairing is supported by the wing. The fixed cowl is attached to the engine and the movable cowl is supported by hinges from the fixed cowl. B. The engines are mounted by cone bolts at two points forward and at a single point aft. The forward mounting, with thrust links, takes all thrust loads plus vertical and side loads. Engine vibration isolators are installed at the structural engine attachment points. The engine support fittings are designed to allow for thermal expansion of the engines. C. The forward attachment fittings consist of a steel forging suspended from fittings attached to wing structure. The aft attachment fitting is suspended from the outboard track of the inboard flap. D. Engine hoist fittings, with protective covers are installed on the surface of the wing.
