Abstract
Each convergent flap and seal has a cantilevered extension deflector. This deflector reduces the throat area at minimum throat area, and seals against a divergent flap or seal in the maximum throat area position. Cooling ambient air is induced through openings in the upstream portion of each divergent seal at intermediate throat areas. At minimum throat area the divergent flaps block these openings. At maximum throat area the deflectors block the cooling airflow path.
