The drag is actively modulated by energy beams (110) which may either increase or decrease the drag.
The wave drag and the boundary layer drag are part of the shock drag.
The viscous drag on the bubbles is much smaller than that on the surrounding solid surface and the net drag on the entire submerged surface is less than that on an equivalent solid surface.
Thereby, the drag force on a body could be divided into two components, namely frictional drag (viscous drag) and pressure drag (form drag).
drag rise Mach number
The technical solution is directed towards reducing aerodynamic drag.
The advantage of the present invention is a decrease in the residual drag after braking.
A hydrocarbon-soluble drag-reducing suspension is described, along with a process for manufacturing the drag-reducing suspension.
engine drag power
The drag and lift of the submarine or airship, are given with a distinction between form drag and total drag which included the drag caused by lift.
The aerodynamic drag of the recuperator acts in the reverse direction.
Skin friction is responsible for around half of the total drag on an aircraft.
A drag reduction device between carriages of a high-speed motor train set is used for damping air drag.
The aim of the invention is to reduce drag.
The main sources of friction are rolling friction and fluid drag (air drag or water drag).
