Air is everywhere on the earth. The flowing air can change the moving path of the object. The faster the air moves, the greater the energy is. The jet airflow can isolate some objects. So when we make use of the airflow, we can protect ourselves from the rain drops. Then the airflow forms an umbrella without a visible cover. 

Based on this idea, we designed various types of air umbrella with postgraduates from Nanjing University of Aeronautics and Astronautics from July in 2012 to August in 2013.We also tested the air umbrellas on rainy days. 

Luckily, one of our samples achieved the goal of protecting one or even more persons from the rain in the test in November 2012. But the product still needed more improvement. As the sample was designed to take a large amount of airflow, the top was big, which didn’t achieve the portable characteristic.

To design a better looking product, we cooperated with a few PhD graduates from  Beijing University of Aeronautics andAstronautics to improve the design. After a year’s hard work, we finally improved the appearance of the umbrella which may influence the effect. But at least, we could really use it outdoor on rainy days. 

In July 2014, we finished the new sample and colored the product to make it better-looking. And this sample is what we show as air umbrella-b in out pictures and videos.

Currently, we only put the air umbrella-b into practice. According to different demands of various users, we designed two more types of umbrellas based on air umbrella-b (basic style), that is, air umbrella-a (for female) and air umbrella-c( scalable). 

Based on the appearance of umbrella-b, we made design drawings of air umbrella-a and air umbrella-c for your reference.

Air umbrella-a is mini and could be put in bags,It is about 30  centimeters  in  length and 500 grams in weight,It is not scalable.The battery life is about 15 minutes.

Air umbrella-b:it is the basic style.The umbrella is 50 centimeters in length and 800 grams in weight.The battery life is about 30 minutes.

Air umbrella-c is scalable.It is about 50 centimeters after shortened and 80 centimeters after extended.The umbrella weights about 850 grams.The battery life is about 30 minutes.
