Abstract:
1. An on-board, ventilating airflow management system dedicated for use in operative association with the electrical sliding-contact zone in an aircraft rotary electrical generating device, said system, in operative condition, comprising an air intake (a) spaced from the electrical generating device and from the aircraft engine, (b) independent of the aircraft engine and (c) disposed to intake a flow of air under circumstances with the aircraft engine operating, elongate fluid-flow conduit structure having (a) an intake end disposed adjacent said air intake for receiving an airflow therefrom, (b) a discharge end including a fluid-flow connector which closes upon the mentioned electrical sliding-contact zone, whereby said discharge end, via said connector, is tightly coupled to said electrical sliding-contact zone for directing thereinto, substantially solely, all airflow, and only from that which is received at the conduit structure's said intake end, and (c) a fluid-flow path extending between and communicating with said intake and discharge ends, and particulate filter structure operatively disposed in said conduit structure's said fluid-flow path, intermediate said intake and discharge ends, adapted to prevent particle passage through said connector into the operatively associated electrical sliding-contact zone.
