Ultra micro UAV "Dragonfly" or into the next street fighter and reconnaissance tool (1)

No flapping wing ultra

Referred to the modern war, many people will think of armoured vehicles, the first aircraft, fighter these large weaponry, but in the near future, a shape like a Dragonfly-like size, the weight is only 10 grams, compared with ordinary airplane also small MAV may play out more powerful than traditional weapons, be decided the outcome of a battle.

According to the United States fun science network coverage, United States Department of Defense Advanced Research Project Agency (DARPA) is funding a group named "ultra micro UAV (NAV)" project, developed a complex and free flight in a building of mini-unmanned reconnaissance aircraft.

This aircraft can be manipulated by man-portable, street fighting and other special environment of combatants of battlefield intelligence, in a timely manner to avoid unnecessary loss of life.

Half hand large mini aircraft

"Ultra micro UAV" project aims to urban street fighting developed a super light, super small unmanned aircraft, the aircraft can fly in indoor outdoor climbing, downhill with vertical and horizontal fly around.

According to the research and development requirements, the aircraft fuselage each direction of dimensions should not exceed 7.62 cm and a maximum flight speed of 32 km, to be met in the Interior of the hourly 1.6 km speed-speed flying, can withstand a speed of 8 km of gust, the job should reach 2.4 km, could be sustained flight at least 20 minutes.

The initial phase of the project has a total of Lockheed Martin Corporation · advanced technology laboratory group, de Carepa laboratory, aviation environment firm and micro-promoting company 4 firms and research institutions involved.

The current project has entered the second phase, each institution has published its design or prototype. Lockheed Martin adopts · single-chip flying wing design, de Carepa laboratory with coaxial dual-rotor design, aviation environment firm and micro push companies to adopt a class respectively bird flapping-wing design and insects flapping-wing design.

Which Lockheed Martin adopts · single-chip flying, aircraft through its own high-speed rotation lift, the captain about 3.8 cm maximum takeoff weight 10 grams, the payload 1.98 g, comes with communication and navigation equipment and batteries.

While the United States aviation environment firm design looks more like a hummingbird, its published prototype to 10 g, itself bring energy, relying on two wings of vibration for propulsion, may be at a low altitude. The company stated that the second phase of the project will be completed this summer, when the aircraft traveling will reach 11 minutes to 20 minutes.

United States Department of Defense Advanced Research Project Agency stakeholders appraisal that ultra UAV will present human aerodynamics and energy conversion efficiency of technology are pushed to the limit, will be a milestone in aviation technology, this aircraft will allow the current urban environment of military surveillance capabilities have been significantly improved.
