Expandable aircraft section

An expandable aircraft section, comprising:

• a rigid stationary aircraft portion defining an enclosed cavity;
• a rigid movable aircraft portion forming a closure of the cavity;
• an elastomeric transition section attached between the rigid stationary aircraft portion and the rigid movable aircraft portion permitting the rigid movable aircraft portion to move relative the stationary aircraft portion between a contracted position and an expanded position to increase the volume of the cavity;
• wherein the rigid stationary aircraft portion forms a weapons bay and the rigid movable aircraft portion forms a weapons bay door.

A fairing for an expandable aircraft bomb bay, the bomb bay having at least one bomb bay door extending along a side edge of the bomb bay, said fairing comprising:

• a rigid member having an aerodynamic surface;
• a mechanism to attach the rigid member to the aircraft and move the rigid member between a retracted position and an expanded position relative the aircraft;
• and
• an elastomeric transition section attached between the rigid member and the aircraft at an edge of the bomb bay extending at an angle relative the side edge.
