Speedo uses ANSYS tool to develop Fastskin Racing System

Competitive swimmers this summer can streamline performance thanks to Speedo's revolutionary Fastskin Racing System, whichwas designed using engineering simulation software from ANSYS. When worn together as a complete system, a Fastskin suit, cap and goggle can reduce full-body passive drag by up to 16.6 percent, improve oxygen economy by up to 11 percent (enabling the athlete to swim stronger for longer), and reduce active body drag by up to 5.2 percent.

"Engineering simulation has been absolutely critical in launching this world-first concept," said Tom Waller, head of Speedo's in-house global research and development facility, Aqualab. "For the first time, competitive swimmers can use a cohesive, hydrodynamic solution that will help them cut through the water with maximum efficiency.

“In developing the Fastskin Racing System, ANSYS software gave us the confidence that our designs would perform as expected in the real world — and saved us a huge amount of resources that we would otherwise have had to invest in physical testing."

In engineering the three components into a system, Aqualab used data from more than 1,200 separate simulations conducted with ANSYS multiphysics software. By replicating the dynamic pressures of competitive swimming in a risk-free virtual design environment, these simulations helped engineers to minimize the effects of turbulence and drag, mitigate the impact force generated by a dive, maximize the structural strength of the goggle assembly, and address other real-world design concerns.

Following the design work, Speedo conducted a number of pool tests of the new racing system, using professional athletes including Natalie Coughlin, Ryan Lochte and Michael Phelps of the United States.

While Speedo is a long-time ANSYS customer, development of the racing system relied on an expanded, multiphysics perspective that included both fluid dynamics and structural mechanics analyses.

For the goggles, for example, ANSYS solutions offered insight about the structural forces that impact the equipment from all directions, which lightweight material would be able to withstand those forces, and how the shape generated turbulence that could negatively impact the swimmer's downstream performance.

This broader approach matches the new, forward-looking portfolio of products that Speedo is developing to meet swimmers' full-body needs.

"ANSYS has a long history of working with leading organizations to produce winning products — whether it be a swimsuit that helps to shave fractions of a second off an elite athlete's performance or a hybrid vehicle battery that delivers optimal value in terms of cost, reliability, energy usage and safety. We are proud to partner with Speedo in engineering yet another groundbreaking product," said Jim Cashman, president and CEO of NSYS.
