These are a result of increased turbulence and entrainment of air at higher altitudes by the simulated turbines.

Surrounding air is drawn into the airflow, amplifying it six times in a process known as inducement and entrainment.

"The animals are conceived to be 'traveling machines' instead of big thrills entrainment, " said its co-artistic director Francois Delaroziere.

And, similar to Dyson, Lugg is proposing to achieve these radical efficiencies by coordinating multiple engine systems (analogous to the acceleration, inducement and entrainment of the Air Multiplier) to create optimal conditions for each stage of flight and to use the excess energy the system produces to create a plasma field to reduce drag and eliminate sonic boom.
