An airship comprising a hull (102,104) configured to be inflated with a first gas; a ballonet (106,108) in the hull, the ballonet configured to be inflated with a second gas that is heavier than the first gas; a fan (118,120) configured to draw the second gas into the ballonet; an inflatable landing system (122,124); a duct (110,112) configured in the ballonet to allow access to components in the airship; and a valve (126,128) coupled to the ballonet. The valve provides a pathway for air to flow between the ballonet and a plenum chamber (130), the plenum chamber is formed by the airship, a landing surface, and the inflatable landing system when the inflatable landing system is in contact with the landing surface. |
