An Acrobatic Airship ‘ACROSTAT’ 911994

A novel type of airships or a powered LTA aircraft has been proposed, which is designed with a rather conventionally shaped hull and with conventional thrusters and is not made as a control configured vehicle(CCV) nor utilized any sophisticated control mechanism. None of control surfaces are installed but couples of stabilizers equipped to the aft hull, and without any active control tricks the vehicle holds its stability and realizes enhanced maneuverability performances. This newly conceived type model is named as ‘ACROSTAT’. This airship can ascent and descent vertically, and can perform somersaults, spiral flights, and rotates around its C.G. as the center of the movement. The paper deals with the structural design concept of the model, design data and the attitude control principle.
