Abstract
A static pressure regain coupler for coupling an input duct and the upstream end of a branch take-off device having a main duct and one or more channel. The static pressure regain (SPR) coupler includes an upstream end which has substantially the same cross-section as the input duct. The SPR coupler also includes a downstream end which has a first port having the same cross-section as the main duct of the take-off device, and a second port having substantially the same cross-section as the channels of the take-off device. The SPR coupler is adapted to couple most of the input airflow to the take-off main duct, and a minor portion of that air flow to the take-off channels.
