US military scientists have designed a miniature drone, Cicada, which can be used on civil missions and in wars. Cicada stands for Covert Autonomous Disposable Aircraft.

“The “micro air vehicle” is named after the insect that inspired its invention, the Cicada, which spends years underground before appearing in great swarms, reproducing and then dropping to the ground dead,” according to Discovery News.

AFP reported that it is designed to be smaller, cheaper and simpler than any other robotic aircraft but is still able to carry out a mission in a remote battlefield.

Aaron Kahn, a flight controls engineer at the Naval Research Laboratory, told the news agency, “The idea was why we can’t make UAVs (unmanned aerial vehicles) that have the same sort of profile.”

“We will put so many out there, it will be impossible for the enemy to pick them all up,” he added.

The prototype model has cost just a thousand dollars, and Kahn also stated that the cost could come down to as low as $250 a piece.

Despite of its small size, the Cicada drone can fly at about 46 miles (74 kilometers) per hour and is fairly silent, as it has no engine or propulsion system.

Daniel Edwards, an aerospace engineer at the Naval Research Laboratory, said, “It looks like a bird flying down,” adding that the drone is “very difficult to see”.

The researchers have said that these miniscule-drones can be used for a multitude of missions, from weather forecasting or monitoring traffic on a remote road, beyond the enemy lines to eavesdropping on enemy troops.

Kahn said, “You equip these with a microphone or a seismic detector, drop them on that road, and it will tell you ‘I heard a truck or a car travel along that road.’ You know how fast and which direction they’re traveling.”

“They are robotic carrier pigeons. You tell them where to go, and they will go there,” Edwards told AFP.

Edwards added that despite their toy-like appearance, the Cicada drones are surprisingly robust.

“They’ve flown through trees. They’ve hit asphalt runways. They have tumbled in gravel. They’ve had sand in them. They only thing that we found that killed them was desert shrubbery,” he said.

The news agency reported that academics and almost every branch of government have expressed an interest in the Cicada program, including some intelligence agencies.

“Everyone is interested. Everyone,” Edwards concluded.

New Delhi, November 2, 2017: E-commerce players like Amazon and Flipkart will be able to make airborne delivery of products to customers in India using drones enabled by technology being developed by the country’s aviation sector, a minister announced on Thursday.

“E-commerce deliveries using drones are certainly going to be possible in India. Companies like Amamzon and Flipkart can deliver products with the tecnological developments we are seeing in the aviation eco system,” Minister of State for Civil Aviation Jayant Sinha said at the Aero Expo 2017 here organised by the PHD Chamber of Commerce.

The Directorate General of Civil Aviation (DGCA) on Wednesday invited public comments on the draft rules on use of drones, including for commercial purposes, which the aviation regulator hopes to finalise by the year-end. Drones have been classified under five categories based on their weight.

“Aviation is at the cutting edge of technology be it in avionics, software..throwing open the drone industry to experimentation and innovation will really benefit India,” Sinha said.

Noting the various uses of drone technology in areas like oil and gas prospecting, agriculture and in taking pictures, Sinha said use of drones as “air rickshaws” for travelling around a 100-km radius could be a viable proposition.

A few years ago, a drone had been used to deliver a packet to a location at a multi-storeyed building Mumbai. The local police, however, described it as an unauthorised flight in violation of rules.

Noting that this government had brought in the National Civil Aviation Policy, Civil Aviation Minister Ashok Gajapathi Raju said that the sector had notched up 20 crore passenger trips this year, which exceeded the Railways’ 13 crore passengers in their upper class coaches.

“Our journey, however, has only begun because only 3 per cent of Indians actually fly. With our efforts to increase connectivity, we are aiming at 30-40 per cent,” the minister added.

Vice President Venkaiah Naidu was among the chief guests at the event and released a knowledge paper on the sector.(IANS)
