ABSTRACT:
A temperature control device for a jet aircraft engine installation that includes a jet engine and a nacelle for supporting and enclosing the jet engine. The jet engine has a primary exhaust nozzle from which the engine produces a rearwardly extending primary exhaust plume of hot gases. The primary exhaust plume has a centerline and a generally cylindrical shape about its centerline. Each engine installation includes a nacelle-associated structure, such as a support strut, that extends in a generally fore and aft direction above the centerline of the primary exhaust plume. The temperature control device comprises a deflector formed at the lowermost surface of the nacelle-associated structure. The deflector includes a sheet-like lower surface having a lateral extent greater than the lateral extent of the nacelle-associated structure immediately above the deflector, and extends longitudinally aft of the primary exhaust nozzle. The deflector is positioned such that its lower surface is generally parallel to the primary exhaust plume.
