ABSTRACT:
A duct for aircraft use which has ease of use and will resist degradation over time. Silicone impregnated cloth is supported by a nylon helix and covered with a protective braiding of KEVLAR.RTM., a commonly used polyamide fiber. The resulting tube can be strung through tight openings. The duct is equipped with a flexible flange for secure engagement. The flexible flange can be collapsed to reduce the cross sectional area for fitting through narrow openings.
