A large part of the aircraft is not optimized to reduce turbulent friction
What we make
Our technology reduces turbulent drag by up to 4%. We develop surfaces with smooth and shallow indentations that reduce skin friction in a turbulent boundary layer. Designs are unique to specific environments and applications. You'll go further, faster, and do it greener.

This is no golf ball

We use dimples in an innovative way that is fundamentally different to the classic golf ball. Our surfaces establish a finely tuned steady pressure field, which suppresses near-wall turbulence in the boundary layer. The Dimple team has published several scientific papers outlining the main flow concepts:

Key benefits
A low-cost worry-free approach to reducing fuel consumption

Passive


Our surface is passive, it just works. There is no energy expenditure and it has zero moving parts. It is inherently simple, cheap, and light.


Fuel savings


Our surface technology improves areas where no other attractive solution is available, reducing fuel consumption substantially.


Low maintenance


Our geometries are smooth and shallow making them compatible with standard cleaning and maintenance procedures.


Retrofittable


The technology can easily be retrofitted to existing aircraft panels in order to obtain significant fuel savings.


Low design impact


The shallowness of our geometries allows skin panels to be treated as normal panels during the design process.


Widely applicable


The surface works in fully turbulent flows making it applicable to more than 90% of the wetted surface of aircraft.

Turbulence is everywhere
Our surfaces are applicable to other applications involving long fully developed turbulent boundary layers. This includes hulls of large marine vessels, high-speed trains, and the interior of transmission pipelines.
