Abstract
A mast which is retractable to a lesser height and volume, and deployable to a greater height, and which when deployed can survive a very high temperature event. All structural elements which are required for structural integrity while the mast is deployed are rigid members made of high temperature resistant material. Where the ends of structural diagonals must move toward one another during retraction, that diagonal is provided as a rigid body of two relatively sliding parts which can be latched in an extended condition when the mast is deployed. A lanyard is provided for unlatching and retraction purposes, which may be sacrificed to a high temperature event.
