摘要
A non-rigid hot-air airship with a turboprop drive can be used as an airborne advertising hoarding for daytime and nighttime advertising flights. The streamlined nylon balloon ship's hull has divided chambers which are open underneath, and the balloon space is connected to the nozzle overpressure control flap behind the gondola. In addition, in each case one turbine engine is fitted which, with the adjustable heat distributors, blows the lifting hot air into the respective balloon chamber, and the propellers which are coupled in at the same time drive the hot-air airship to provide its own movement drive. During take-off preparations, the balloon ship's hull can be inflated only by its turbine set using the propeller air, after which only heat blown in from the turbine is then used. In the event of a fully hot or cold air supply, the airship rises or falls on the spot as a result of which a high manoeuvring capability is made possible during takeoff or landing. If severe weather suddenly occurs, the flexible non-rigid hot-air airship is quickly deflated, packed together and can be moved to a fine-weather area in order to carry out new operational advertising flights. The transparent nylon balloon can be transilluminated from the interior during darkness, and the production surfaces of the balloon inner sides allow slides, illuminated moving lettering or multi-coloured moving airborne image advertising to be projected.
