An international team of scientists has developed a new aerodynamic fairing for the helicopter rotor head, which significantly reduces drag during forward flight.
Due to the possibility of vertical take-off and landing, helicopters are an indispensable aircraft today. However, they consume a lot of energy to travel and travel slower than aircraft. This is due to the presence of the rotor, which creates strong resistance during cruise flight..
A research team from the Technical University of Munich and Airbus Helicopters announced the development of an aerodynamically optimized rotor fairing. New head shape retains (stabilizes) airflow to minimize turbulence.
Types of Rotor Systems in Helicopters
Computer models have shown that the use of an improved rotor will allow the helicopter to fly at speeds of up to 400 km / h. The group is currently working on the production of the first rotors of a new type, after which it will proceed to flight tests..
Late last year, researchers began testing a new jet engine that would allow planes to fly 16 times faster than the speed of sound..
