Iranian students at Tabriz University designed an Unmanned Aerial Vehicle (UAV) flying at 15,000 feet.

Fars News Agency reported that researchers at the Modern Technologies Engineering Collage of Tabriz University developed the drone, dubbed as Shaparak (butterfly), which can keep flying at 15,000 feet and a range of 20 km.

One of the designers of the drone said that the long period of constant flying at high altitudes is one of the main feature of the newly designed drone. "These types of UAVs are able to keep flying for 3 hours and have the capability to increase their length of flight to 20 hours," the designer said.

The small size Shaparak weighs 55kg and enjoys the capability to carry a maximum 10kg load and conduct night flights.

The UAV can take off in three seconds.
