Chinese authorities conduct drone-aircraft collision tests


Beijing - Civil Aviation Administration of China conducts collision tests between the drones and a passenger aircraft. The purpose of the tests is to study the safety risks of collision between drones and civil aircraft.

The results of the study will serve as the technical guidance and decision-making basis for drone operations, management rules, and design and manufacturing as well.

The maturity of drone-related technologies and the increasing interest of people, make these devices more and more popular. Today, drones are widely used in many fields such as emergency rescue, environmental monitoring, power line inspection, aerial mapping, and agricultural plant protection.

However, the rapid growth in the number of unmanned aerial vehicles also led to an increase in incidents. There have been close enc─▒unters between drones and civilian passenger planes in many countries. The European Aviation Safety Agency (EASA) 2010-2016 statistics report shows that there were almost 1000 collisions or almost collisions of unmanned aerial vehicles within Europe, among which three were confirmed as a drone-Civil aircraft collision that caused different degrees aircraft structural damage and economic losses. Federal Aviation Administration (FAA) statistics show that the risk of drone - civil aircraft encounter events soared since 2014.

From the perspective of safe operation of civil aircraft and travel safety of passengers, the impact of drones on the safety of civil aviation operation is immeasurable and has drawn wide attention from government departments, research institutes, and scholars.

Although domestic and foreign airworthiness authorities carried out preliminary tests and simulation studies on the safe operation of drones from the perspective of safety risks, providing preliminary technical support for the development of airworthiness management and operation policies of UAVs in various countries, there is a lack of necessary technical basis in the assessment of crash damage between drones and passenger planes, CAAC says.

The crash simulation tests that were jointly carried out by Nanjing University of Aeronautics and Astronautics, Northwestern Polytechnical University and Shanghai Aircraft Design and Research Institute show that the UAV manufacturing material, flight attitude, flight speed, volume, weight and the collision position of the aircraft and other factors have different degrees of impact the aircraft body structure.
