Abstract
A thrust reverser having a multi-panel construction is disclosed. The thrust reverser has a main door operatively associated with a deflector panel. The door and the deflector panel are pivotally attached to the housing so as to pivot about axially displaced pivot axes. The deflector panel and a downstream inner door panel surface extend along an ideal for flow line between the stationary upstream housing portion and the downstream housing portion when the thrust reverser is in the forward thrust mode. A cavity is defined between an upstream stationary housing portion, an upstream inner door panel surface and the deflector panel communicates with the ambient atmosphere such that the pressure acting on the upstream inner door panel surface is substantially equivalent to the ambient air pressure. The relationship between the upstream inner door panel surface and the downstream inner door panel surface is such that the higher pressure in the cold-flow air duct, which acts on the downstream inner door panel surface, urges the thrust receiver door toward its closed position.
