Abstract
A system and method for actuating a hatch door. One embodiment includes a vertical launcher system that has a hatch door disposed in a plane at the top of a hold. The hatch door includes a leading edge and a trailing edge at opposite ends of the hatch door. When an actuator arm for maneuvering the hatch door is extended, the leading edge is lifted away from the plane by the actuator arm while the trailing edge remains in the plane and slides across the top of the plane toward the point where the leading edge was first lifted away. Such a sliding hatch mechanism allows for quick opening and closing of a hatch door while providing more efficient use of mechanical energy for breaking ice build up or prevent intrusion.
