Construction problems
micro aerial vehicles operate at lower speeds smaller dimensions
mechanizing mav at low Reynolds numbers difficult
complication of MAV minimize the overall size of the MAV maximize the available lifting wing area, the chord and wingspan should be roughly equal to each other.

Bomb attacks
Terrorist bomb attacks have become a major problem of world
2008 world has faced 162 bomb attacks
India has faced 14 bomb attack till November 24.

mav tower explosives
Sensors explosives release their own vapor
particles via leaks in the sealment of the explosives
bomb-detecting sensor Ion Mobility Spectrometer "Sensor A," developed to "sniff out" leaked particle clusters of C4 and other explosives a method based on ion mobility spectrometry technology.
their detection is often marked as a cloud general area of the explosives.
sensors Sensor B explosives were securely sealed to
prevent leaks, utilizing the combined use of a neutron scintillator and a hydrogen bomb detector.
Instead of detecting any ionized particles released from the explosives, Sensor B detects the explosives themselves
via neutron emission and picking up rear diffusion due to neutrons interacting with the hydrogen material inside the explosive.
