Abstract
A flow management system for delivering air to a heat load of an aircraft includes a cover having an opening for receiving and directing an airflow, and a duct defining a non-linear fluid flow path. The fluid flow path operably couples the opening and the heat load. A configuration of the fluid flow path reduces a velocity of the airflow therein while minimizing a pressure drop of the airflow.
Claims17
A flow management system for delivering air within an aircraft, the system comprising:
- a cover having an opening for receiving and directing an airflow;
- and
- at least one duct defining a non-linear fluid flow path, the fluid flow path operably coupling the opening and an area within the aircraft, wherein the at least one duct comprises a baffle extending from a portion of the at least one duct, wherein a cross-sectional area of the at least one duct downstream of the baffle is greater than a cross-sectional area of the at least one duct upstream of the baffle, and wherein the baffle and a portion of the at least one duct downstream of the baffle reduce a velocity of the airflow within the at least one duct and a pressure drop of the airflow,
- wherein the at least one duct comprises:
- a first duct member;
- and
- a second duct member configured to cooperate with the first duct member to define at least a portion of the fluid flow path,
- wherein at least one of the first duct member or the second duct member has a first end and a second end and is disposed to contact the cover at the first end and disposed to contact an airframe of the aircraft at the second end;
- wherein the baffle is disposed at the first end such that the baffle is adjacent the opening and extends in a direction away from the cover;
- and
- wherein a lip is arranged adjacent a terminal end of the second duct member, the lip extending in a direction perpendicular to the second duct member into the fluid flow path, wherein the lip forms a v-shape such that an apex of the lip is disposed at the terminal end of the second duct member, and portions of the lip forming the apex extend away from the terminal end and toward the opening.
