ABSTRACT:
In accordance with the present invention, there is provided an aircraft engine air intake cover for use with an air intake which is characterized by an air velocity profile therewithin. The air intake cover is provided with an air induction plate which disposed across at least a portion of the air intake. The air intake cover is further provided with a multitude of air induction ducts. The induction ducts are disposed about and extend through the air induction plate. Each induction duct has a duct inlet, a duct outlet and a duct body interposed between the duct inlet and the duct outlet. The duct inlets each respectively define an effective inlet diameter. The duct bodies each respectively define a duct body length which is greater than the associated effective duct inlet diameter. The duct outlets each respectively define an effective outlet diameter greater than the effective inlet diameter for increasing the cohesiveness of the air velocity profile within the air intake.
