Low-drag

Describes a design or shape that minimizes resistance to movement through a fluid, such as air or water. This resistance, called drag, slows down objects. 'Low-drag' designs aim to reduce this drag, allowing for increased speed, efficiency, and fuel economy. This principle is fundamental in aerodynamics and hydrodynamics, impacting the performance of vehicles, aircraft, and even aquatic creatures. It is achieved through streamlined forms and smooth surfaces that prevent turbulent flow and reduce friction.

Low-drag meaning with examples

• The sleek, low-drag design of the new sports car contributed significantly to its impressive top speed and fuel efficiency. Its smooth, curved body minimized air resistance, allowing the engine to propel it forward with greater ease. Extensive wind tunnel testing ensured the car's optimal aerodynamic performance.
• Engineers meticulously crafted the airplane's wings to achieve a low-drag profile. The optimized wing shape and smooth skin minimized air turbulence, reducing fuel consumption and increasing flight range. This design allows it to soar smoothly through the air.
• Competitive swimmers often wear specialized suits designed to be low-drag in the water. These suits compress the body and reduce friction. This small detail can significantly impact race times and allow the swimmer to move easier.
• The submarine's hull was engineered to be exceptionally low-drag, allowing it to move through the water with greater speed and less energy consumption. Its rounded form, devoid of protruding features, helped reduce the water's resistance.
