ABSTRACT:
A drogue for drawing an elongated item through a conduit is disclosed. The drogue includes a flexible bag having a closed end and an oppositely disposed end opening. Shroud lines attached to the bag at the end opening allow attachment of the drogue to the item. A biasing member, preferably in the form of a continuous loop of flexible, resilient interconnected wire legs, is attached to the bag and positioned proximate to the end opening. The loop engages the bag over a portion of its length and biases the end opening into an open configuration to prevent its collapse and loss of pneumatic pressure as it is propelled through the conduit.
