The model represents a classic hot air balloon carrying two people and its measurements try to replicate the shape and proportions of a real balloon. For this reason the model itself is quite big. In order to reduce its weight, the balloon has an internal structure made of Technic bricks. The structure is composed by one central pylon and eight radial arc beams. Each piece of the envelope (the colored part) is connected to one of these eight braces. The stiffness of the structure is obtained with diagonal beams. The colors chosen for the envelope are eight and are the most common used in hot air balloons. Despite the dimension of the model, the building process is quite simple and repetitive. In fact both the internal structure and the envelope are modular parts. I put much care in the creation of the model, chosing the best angles in orde to avoid any gap between the bricks in angular connections.
---About me--- My name is Luca and I'm an aerospace engineering student at the univerisity of Pisa. My great passion for flying machines guided me through the creation of this model. I would share with other people the beauty of aircrafts. But despite all, my great passions are Star Wars and Lego bricks.
This hot air balloon model is dedicated to my girlfriend Sofia.
