To obtain an easier-to-build airship, the design has a flat underbelly. This shape has clear and pragmatic advantages in construction, but needs to be verified as an aerodynamic concept.<\/p>\n

To this goal an experimental, remote-controlled model was realized in the Verbeke Foundation. Construction materials are Mylar foil, carbon fiber and Dyneema wire. Overall mass is 6,6 kg for a length of 8,6 meters. It is filled with helium.<\/p>\n

Developing this model in a public space inside an arts center has had several advantages.
\nIt allowed for the presentation of the project as a work-in-progress.
\nShowing the experiments, instead of the final results, facilitates discussion about research as a progressive series of experiments and tests through trial and error. The essence of science and engineering cannot be found in the end result, it is in the process.
\nThis is a story that is seldom told, as our engineers are trained to work behind closed doors and only present successful results.<\/p>\n

As a consequence, the model is not presented as a glossy, finished object. Epoxy repairs, tied-on extra parts and the Scotch tape on the gas bags show the modifications that were made during testing & development.<\/p>\n

The model has an animatronic spine. Actuators control two vertical and three horizontal hinges. Bending this spine distorts the outer envelope. The gasbags slide over each other.<\/p>\n

These deformations can be used to control aerodynamic lift and allows the ship to steer along its yaw axis.<\/p>\n

The model was further developed into a remote-controlled, flying model.
\nA conventional RC steers the device, sending signals to 2 onboard Arduinos. Xbee radios providing a telemetry link.<\/p>\n
