Abstract:
A pressurized airflow generating system adapted for use with an aircraft to provide an air curtain adjacent a portion of said aircraft, and wherein said aircraft includes a power unit for generating a pressurized airflow, said system comprising:at least one air intake duct operably associated with said aircraft to enable an ambient airflow to be drawn into said air intake duct; an intake fan operably associated with said air intake duct for drawing said ambient airflow into said air intake duct and creating an intake airflow having a first velocity within said air intake duct; a manifold having an inlet and an outlet, said inlet being operably associated with said air intake duct to receive said ambient airflow drawn into said air intake duct; a conduit having a first end in flow communication with said power unit for receiving said pressurized airflow, and a second end; an injection nozzle in flow communication with said second end of said conduit for injecting said pressurized airflow into said air intake duct in the same direction as said intake airflow; and said pressurized airflow operating to accelerate said intake airflow to produce a high pressure airflow having a second velocity greater than said first velocity through said outlet of said manifold to thereby form said air curtain.
