Abstract
A nacelle assembly provides thrust reverser doors and core cowl doors with separate thrust reverser door hinge lines and core cowl doors hinge lines for independent operation to eliminate the requirement of a lower bi-fi splitter. The removal of the lower Bi-Fi splitter provides improved aerodynamic packaging with improved performance by reducing drag in the bypass fan stream.
