AT_airship_(heated) 3D Model

3D model of the AT airship (heated LTA-gas version). The AT airship is an airship intented for (world) travellers; it is used similarly as an RV/camper. It can carry 2 people, aswell as 90 kg of cargo and 90 kg of ballast. The airship design is very small in comparison to most airships, and was made as light as possible, while also including some special features. Most notable features are: the use of a heated lighter-than-air (LTA) gas as lifting gas, and propellers that push the airship towards the ground (and propell the airship), rather than generating lift (and propell). The airship is continuously filled with a little too little LTA-gas (ie hot air) so that it continuously wishes to descend (lightly), hence requiring the burners to increase the temperature of the air in the balloon once and a while to generate lift and bring it to its starting altitude again. The propellers are non-rotatable; the propulsion is electric and has an integrated pedaling system for the recharging of the battery. A water tank functions as a battery management system, ballast and as a water source; a supporting floor is not present (a catwalk and seats are used instead), the propeller motors are used as a heat source, … The winches are still present to allow winching up people and for mooring, although they are no longer essential as this airship version can easily land (unlike the unheated airship version).
