The document describes the design and testing of an experimental blimp intended to generate electricity from wind power. The blimp was designed with a vertical wind wheel attached to harvest energy from high-altitude winds. Several blimp designs were tested, starting with complex shapes and moving to a standard zeppelin form. The final design used a typical zeppelin body with two foil surfaces glued together and a lightweight vertical wind wheel and generator. A test flight of this blimp design was able to successfully demonstrate electricity generation from wind power aboard the airship.

2. Structure
• Basic idea
• First designs
• First Blimp
• Second Blimp
• The wind wheel
• The generator
• The test flight

3. Basic idea
• The Blimp is a zeppelin, on which a vertical
wind wheel is fixed
• In a high of 500m is the wind very strong and
blows permanent
 you can produce more electricity
• It don‘t needs a mast, so it‘s cheaper and
better to transport

4. First designs
• Round zeppelin with a wind tunnel
• Problem:
• Complex to form the zeppelin
• Efficiency depends on the wind direction

5. First Blimp
• Cylinder as body,
cone as roof
• Problems:
– Form is too complex,
isnt airtight

6. Second Blimp
• Typical zeppelin form
• Two foils glued on each other
• No Problems, very airtight

7. The windwheel
• Vertical wind wheel
 independence from
wind direction
• Fixed with a
styropor bar

8. The generator
• Problems:
– Generator must be very light, with just a few turns
per minute
We took a motor with a gear
