Claim:
A thrust reverser blocker door assembly comprising: a translating cowl forming an aft portion of an engine nacelle; a translating sleeve slaved for movement with the translating cowl and disposed internally thereto, wherein both the translating cowl and the translating sleeve are able to translate from a stowed position to a deployed position uncovering a gap between the translating cowl and the nacelle; an engine case within the nacelle forming an airflow duct between the translating cowl and engine case; a cascade vane set positioned in the gap; a blocker door that covers the cascade vane set when the translating cowl is in the stowed position and blocks a portion of the airflow duct when the translating cowl is in the deployed position; and a geometrically shaped drag link that is pivotally connected to the engine case at a first end and connected to the blocker door at a second end, the geometrically shaped drag link moving with the translating cowl.
