Nano Air Vehicle

for methane detection

Fixed wing nano air vehicle (NAV), 6 cm long and 4 cm wide. Inspired by the "ballooning" behavior of the spider, it can quickly monitor methane leakages.

Ballooning is a process by which spiders move through the air by releasing one or more gossamer threads to catch the wind, causing them to become airborne at the mercy of air currents, and more importantly, electric currents. 

Curved Charged Wire (electrostatic force)

1.extend battery life & quickly take off - the static interact with the electric field to produce a lifting force.
2.help positioning - with the help of wind, quickly position the spread range of methane

I improved the problem of the short flight duration and stability of the NAV — it emits silk threads with negative charged electrons to generates lift when attempting to repel the same charge in the air.

With restrictive sizes, NAVs can travel in “swarms”. They work together and communicate with each other through a control center so that a large number of NAVs can quickly detect methane leakage.
