ABSTRACT:
An integrated power plant installation system for underwing high-bypass mid-length fan air duct core-mounted engines readily permits disconnection of the entire powerplant at the wing thereby virtually eliminating the necessity of disconnecting the engine and complex systems per se from the support strut when engine replacement or removal proves necessary. Excessive congestion within the vicinity of the strut box structure is eliminated by disposing the engine accessories, and auxiliary equipment and system lines, within the lower quadrant of the powerplant assembly in both a laterally and longitudinally distributed array. Potential catastrophic fire hazards within the nacelle are substantially eliminated by routing the fluid lines and electrical conduits axially aft and upwardly around the circumference of the engine within the nozzle section of the powerplant aft of all rotating discs. These latter features permit the utilization of a simplified strut box structure in that the same need not be provided with equipment clearance structure, conduit throughbores, and complex fire seals and drains. The strut structure is easily tunable with simple plate structure for flutter stiffness control, involving strut and wing bending in gusts. The wing attach/detach engine mounting system, particularly for a core-mounted engine by means of the simplified strut box structure, also facilitates the elimination of the conventional fan D, or split, duct system and enables the employment of a continuous hoop structure thrust reverser system.
