Flexible conduit for guiding exhaust gases from a jet engine, particularly for aircraft use. Said conduit is intended for attachment to the discharge end of a jet engine for redirecting the flow of propellant gases, as for either braking or attitude control purposes. The conduit in the preferred embodiment comprises a plurality of base rings pivoted to each other on alternately perpendicular axes with a flexible hose of heat-resistant material provided internally of said rings and a protective skin applied externally of said ring. Preferably serially connected hydraulic means are provided between alternately pivoted pairs of rings to provide hydraulic control for pivoting or flexing said conduit as desired.
