Abstract
A winged hybrid airship (dynastat) combining the advantages of lighter-than-air (LTA) and heavier-than-air (HTA) aircrafts is disclosed. By combining the dynamic lift of low drag, high aspect ration airfoils (e.g., length over chord >10) with the static lift of low drag, laminar-airflow airships, a platform is formed which is capable of prolonged high altitude flight, maintaining station over a given point on the earth, carrying a payload of communications, reconnaissance or meteorological equipment. Solar collection cells and microwave antennas allow for recharging of on board batteries/fuel cells for powering both the airship and on board avionics computers and reconnaissance or meteorological equipment. An alternate embodiment, having strengthened structural members, is able to provide low altitude heavy cargo lift in remote regions regions or cross country transport of goods.
