An unmanned drone is spraying chemicals over Beijing to battle the fog and smog lingering over the city.

The Parafoil plane is designed to disperse smog above China’s cities fitted to a gliding parachute that can carry 700kg of smog-clearing chemicals.

The Chinese government, with help from state-owned firm Aviation Industry Corp of China (AVIC), successfully tested the unmanned vehicles over the weekend at an airport in central China’s Hubei province.

HOW DOES PARAFOIL WORK?

The Chinese government, with help from state-owned firm Aviation Industry Corp of China (AVIC), successfully tested its Parafoil unmanned plane, pictured, over the weekend at an airport in central China's Hubei province. The plane has been designed to disperse smog above China's cities

The device is fitted to a gliding parachute and can carry 700kg of smog-clearing chemicals – three times the cargo weight of common planes.

These chemicals can be used within a 5km radius.

It works by spraying the chemical catalyst, which reacts with the particles in the smog and freezes the pollutants.

These pollutants then drop to the ground.

The soft-wing unmanned aerial vehicle (UAV) is said to cost 90 per cent less than fixed-wing drones currently used to clear the smog.

For several years, China has used aeroplanes and fixed-wing drones to spray the chemicals in the air.

The Parafoil is more accurate, easier to control and has no complicated landing requirements.

China has used planes and fixed-wing drones to spray the chemicals in the air.

Chinese Premier Li Keqiang said China will ‘declare war on pollution after nearly every Chinese city monitored for pollution last year failed to meet state standards.

Even in thick fog the UAV could fly an accurate route,’ engineer Guo Haijun said.

The Parafoil plane ‘could be used to conduct agricultural seeding, emergency rescue and other tasks‘, said AVIC CEO Ma Yongsheng.

At the opening of an annual parliament meeting last week, Chinese Premier Li Keqiang said China will 'declare war on pollution' after nearly every Chinese town and city, including the Hebei province pictured, monitored for pollution last year failed to meet state standards.

State-owned AVIC is the unlisted parent company of Shenzhen-listed AVIC Aircraft Industry Corp of China.

Pollution is so severe in Beijing at the start of March that aircraft was grounded, roads closed and tourists numbers hit.

The direct danger posed to human health was also underlined by the World Health Organization.

It was reported that the level of PM 2.5 particles, a key measure of pollution because they are small enough to be assimilated into the blood stream, reached 505 micrograms per cubic meter, far higher than the maximum level it considers to be safe, which is 25.

The problem is far from solved.
