The main and unique characteristic of Solar RC Blimps is that the flight autonomy is incomparable to any other craft. Simply explained ...the volume of the Blimp is calculated to annul the Blimp weight including envelope, electronics, stabilizers, solar cells, batteries, all rest Blimp related and target payload. The result is a fully set Blimp, ready to fly, that is positively buoyant. All the available energy is than used only for motion with minimum losses (mainly on aerodynamic resistance of the envelope). There is no need to use energy to lift payload, components or else as they have “no weight”. A fully set and loaded Blimp will float consuming no energy at all. That is unique to Blimps! Today flexible solar cells with 20%+ conversion efficiency are giving more energy than the Blimp needs for motion and rest electronic onboard consumers. To take advantage of the two above facts the design of the Solar RC Blimp also had to be ground breaking and innovative. Classic Blimp designs with double turn able main motors are great for maneuverability but are adding too much drag on the low part of the Blimp. In the same time the nose (front) of the Blimp is cutting through air making it extremely aerodynamically resistant (see graphic below). So the results are 2 main aerodynamic resistant areas of the Blimp. With that fact in mind we had to redesign the classic Blimp concept. The obvious place for the main propulsion was at the nose (front) of the Blimp.
After several years of trials, errors and corrections we have designed One Main Motor (OMM) - front/nose mounted and the results were finally worthy to be integrated into the Solar RC Blimp concept. We named it UniBlimp. There are several unequivocal advantages of this Blimp design:
The 10 m Solar Blimp is designed for hours of flight autonomy and able to carry a payload of up to 2 kg. It has a single front motor, back reverse motor, stabilizers with ailerons all synchronized for maximum power efficiency. The rail system allows simple payload attachment for various remote sensing equipment. Several subsystems were developed to make this Blimp possible. Most important is the intelligent power distribution unit that is, in essence, an automated switch that diverge the solar power to batteries or system. The power to the Blimp comes from the batteries and the solar modules are in the same time gives energy to the system and charge the batteries. So It flies until sufficient sun power!
