Cyclical thermal management system

1. Field of the Invention A cyclical thermal management system is provided for responding to diurnal heating and nocturnal cooling cycles to maintain a high altitude platform in a geostatic position for long periods of time. The novel cyclical thermal management system utilizes solar energy collection devices to collect solar energy which is stored and utilized to operate physical and chemical exothermic processes for heating the lifting gas of the novel high altitude platform at night and to operate physical and chemical processes during the day for transferring the heat of the lifting gas to maintain a particular geostatic position.The cyclical thermal management system utilizes a recyclable energy storage material which is utilized in not only the cyclical thermal management of heat diurnally but also to provide for seasonal and longitudinal variation by increasing or decreasing the volume of lifting gas or by increasing or decreasing the amount of the energy storage material. The energy storage material also provides for the replacement of lost lifting gas.The novel cyclical thermal management system controls altitude and pitch attitude so that horizontal stabilizers and elevators are not necessary to maintain or control pitch and therefore become optional. The novel cyclical thermal management system is combined with other active systems for reducing the amount of heat processing through physical and chemical processes to maintain a geostatic position.
