As you can see clearly, on this wind tunnel simulation, the main resistance point is at the tip (nose) of the Blimp. That problem is solved by placing motor exactly on that location. By doing that we have not only eliminated the main resistance area but created a high pressure front that is actually “sucking” the air and eliminating the “nose” resistance. In the same time, the added bonus, the speed of the air flowing over the envelope, is accelerated creating a sort of “wind tunnel” that is covering the whole envelope. This “tunnel” effect is especially enhanced in our UniBlimp-Duo (front and back motor) where the front motor is “sucking” the air, directing it over the envelope and the back motor “sucking” it again reducing the time needed for the air to flow, therefore, reducing drag. With this “blimp tunnel effect", as we named it, the effect of cross and side winds is reduced up to 40% what is directly affecting less battery drain.
The other direction was a logical deduction from the single motor concept. Stabilizers with ailerons reverse low stabilizer reverse motor and mount for the batteries and electronics where all that we needed to have a maneuverable and precisely controllable Blimp or Airship. All unnecessary weight was stripped to back up the main concept.
