Pursuing Air Flow Perfection: 90 Years of Wind Tunnel Innovation

TLT-Turbo have a long-standing tradition of supplying wind tunnels especially for the motor vehicle and aerospace industry. TLT-Turbo were among the first to focus on aero-acoustic wind tunnel fans. As a supplier for some of the world’s most prominent car manufacturers, TLT-Turbo aims to become renowned as a global leader in wind tunnel fans and systems through continual innovation and a deeply ingrained passion for performance.

The development of wind tunnel production at TLT-Turbo started with their ancestral company, Dinglerwerke, who built their first wind tunnel back in 1936. Decades later, the company now known as TLT-Turbo, would be responsible for some of the world’s most notable wind tunnel installations. “From the start we set out to establish a tradition of being pioneers and innovators in this field of ventilation as we recognized the significance of these systems for vehicle testing,” says Volker Szemskat, Vice President of TLT-Turbo.

TLT-Turbo’s first wind tunnel installation for the motor vehicle industry was built in 1940 for FKFS (Research Institute of Automotive Engineering and Vehicle Engines) in Stuttgart. It was a low speed wind tunnel designed for wind speeds of up to 72 m/s. This wind tunnel was later taken over by Daimler.

Testing vehicles in wind tunnels started with projects such as Peugeot’s passing a car through the Eiffel Wind Tunnel at the rue Boileau, in Paris in 1914. The goal was to gain information on how to modify the shape of models to decrease aerodynamic drag. Since then these types of tests have advanced significantly and today, they are becoming more and more relevant as a means of testing for reducing pollutant and noise emissions. “Even the smallest gain in the aerodynamic drag leads to a decrease in consumption of fuel,” Szemskat explains.

In total, over the past 90 years, TLT-Turbo have supplied around 70 wind tunnels and test stands, of which about 30 were delivered for the automotive industry. This includes more than 70 customized fans ranging from 100 kW to 88.000 kW with diameters from 1 to 15 meters. Among these are some of the most notable facilities in the world – such as the ONERA (French Aerospace Center) Transonic Wind Tunnel S1 in Modane, France, being installed in 1949, with a 2-stage counter-rotating fan measuring 15 m in diameter with a drive power of 88.000 kW. This colossal fan remains to this day the largest wind tunnel fan in the world being in continuous operation since 1952.

Another example of the longevity of TLT-Turbo’s fans is the wind tunnel installed for Volkswagen in 1965. Its 9-meter diameter fan has been in operation in operation for over 50 years.

“The combination of our experience, with the field-proven performance and long operational life spans of these fans has made us a trusted supplier across the globe,” says Szemskat.

This status has been well maintained over the years with clients including Volkswagen, Ferrari, Ford and Audi coming back to TLT-Turbo for repeat orders.

TLT-Turbo’s 145 years of experience in ventilation design and supply has contributed to the innovations and new methods they have been able to apply to their wind tunnel designs. In 2010, TLT-Turbo supplied a fan for an aero-acoustic wind tunnel for the DLR (German Aerospace Center) which features a special blade and guide vane design for particularly low noise generation as well as composite material for the fan blades. Since then, this innovation has been applied to most of their automotive wind tunnel fans.

“Most often the development of innovations in the application of wind tunnels is guided by the needs of a particular client or the project itself. We need to think on our feet to come up with new approaches to solving challenges that arise as a project unfolds. This then informs future designs and installations and ensures that our offering is constantly evolving.”

Some of TLT-Turbo’s latest field-driven innovations include the application of their ‘Cut-off’ and ‘Lean/Sweep’ design that they have applied to their low speed aero-acoustic fan design to reduce blade tone and broadband noise. “We have also been working with the use of composite materials which has allowed us to apply 3D-geometry on the guide vanes which increases efficiency and overall performance,” Szemskat says.

The use of composite materials is also being applied in their current projects for the CAERi and CATARC automotive research institutes in China. These projects are currently in installation and commissioning phase.

For the past 12 twelve years, TLT-Turbo have changed their focus to the centerpiece of wind tunnels; the fan. “In the past, TLT-Turbo supplied turn-key wind tunnel solutions. From 2007, this offering changed to focus solely on the fan itself as the key component of a wind tunnel system. Our clients still benefit from our extensive experience and expertise in complete wind tunnel systems. This allows us to provide a tailored solution because we understand how the separate components interact with each other,” Szemskat reports.

“This gives us greater scope for customization. Every fan and its project planning is adapted to its specific installation. Stand-alone drive systems with local operation, control and monitoring systems and their connection to the parent digital control system also form part of our portfolio. Our experience with the supply and installation of turn-key wind tunnels means that we are able to recognize the significance of specific wind tunnel features to the design of the fan.”

TLT-Turbo Fan Range Redesigned to Meet Specific Mining Industry Needs

Global ventilation fans and systems manufacturer, TLT-Turbo GmbH, has announced the redesign of its Auxiliary and Booster fan range. Developed in close collaboration with clients, the new designs address both efficiency and cost effectiveness, in a versatile product range that meets the specific ventilation requirements of the mining industry.

Development of the new fan range concept began in early 2015. Following a lengthy global market study to gain an understanding of the market requirements, the range was defined in mid-2017, with fabrication of the first units taking place shortly thereafter. “The development of the Auxiliary and Booster fan range would not have been possible without the input of clients. This ensured that we focused on key market driven requirements including energy efficiency, noise reduction, cost effectiveness and turnaround time,” says Michael Minges, Technical Director at TLT-Turbo Africa, who headed up the fans’ designs.

“To sell these products we needed to ensure close customer relationships and visibility. We are striving to change the industry’s mindset on the use of such fans to ensure proper fan selection for the ventilation required. In optimizing mine ventilation, efficient, high quality Auxiliary and Booster fans can add as much value as surface fan installations.”

TLT-Turbo started commissioning of the first iterations of the fan range towards the end of 2017 within the Sub-Saharan market through its Africa office. From there, they based the development of the various fan sizes of the new range on market interest. The fan designs and their performance validation was completed at the end of July 2019. They aim to complete product roll out, with all supporting documents and certification, by the end of September 2019.

Minges explains that meeting identified market demands was the main focus of the improved designs. “As energy efficiency is one of the main drivers of industrial equipment usage, and minimum efficiency requirements on certain equipment are often legislated, TLT-Turbo identified the need and opportunity in the market for more efficient mining fans compared to what is currently in use.”

The new designs include several innovative additions to enhance performance in order to provide exceptional underground ventilation. The fan range was developed using the latest in engineering flow technology which allowed TLT-Turbo to improve the aerodynamics, and thus efficiency of the fans. A unique stator design and aerodynamic fairings, all manufactured from wear resistant composite materials, result in improved efficiencies and reduced noise levels. The modularity of the fan casings allow for quick and easy assembly with interchangeable ancillary fan parts.  The motor mounting in coherence with a machined impeller track ensures low and controllable blade tip clearances for improved performance and efficiencies. Pad mount motors are used for all fan sizes and help reduce vibration levels in the axial direction of the motor significantly which leads to longer motor bearing life and lower maintenance requirements.

(Above) The first orders for the new range were received at the end of 2017

Minges says that all possible measures are taken to ensure the highest quality and best possible performance of every fan supplied by TLT-Turbo. “All fans are ISO 5801 tested, unless the client agrees to type testing on higher volume orders. We ensure the client quoted performance is met before the fans leave the factory. Test certificates on both raw data and calculated performance can be provided on request. Fan efficiency is determined with the performance test and this quality check ensures we deliver on what we promised the client. Clients are regularly invited to witness the performance tests to sign off on acceptance. The fans also come with pressure ports that can be hooked up to a calibrated handheld measuring device to measure performance in-situ.”

In addition to performance and efficiency, ease of maintenance was also a major consideration in developing the new Auxiliary and Booster range. The modularity of the product design and the interchangeable standardized parts allows for quick turnaround time on parts supply. “For example, we only have two blade types for the full product range and generally only one motor barrel per fan size accommodating various motor sizes and types. Standardization on the product is the key to successfully managing maintenance and repair as it allows ample supply of spares for companies certified to do the repair work. The design track record has indicated a longer mean time between failure (MTBF) than previous products,” Minges explains.

(Above) The new TLT-Turbo Auxiliary and Booster fan range is available to clients worldwide

The fan range is being rolled out in phases. The preliminary testing at sites located in Sub-Saharan Africa has been launched successfully. The next phase is globalization as the new range will be rolled out in the USA, Canada, Europe, Russia and Australia. Following this, product supply and support will be extended to TLT-Turbo offices in South America and India. In the interim though, Minges says that these fans can be supplied to clients worldwide from TLT-Turbo Africa.

TLT-Turbo Africa has received a number of orders for these fans since the end of 2017. These orders include South African clients seeking a solution for deepening a gold mine, and for Kamoa Copper in the DRC as an exclusive supplier. “The feedback that we have received thus far has been that the fans are meeting our and client expectations. I am proud to say that one EPC consultant used the phrase ‘super fan’ to describe the new range and indicated that he has not heard a fan of this size so quiet before,” says Minges commenting on the reception of the new range.

“The Auxiliary and Booster fan range was developed to enhance TLT-Turbo’s mining ventilation product portfolio. The product is based on historic innovative designs by the TLT-Turbo Africa R&D team. Continual product development and keeping up to date with the latest technologies is ingrained within the engineering teams of TLT-Turbo. Ensuring that innovations are market and client driven with the end result being a benefit to the industry, puts us in the forefront of advancement in ventilation solutions,” Minges concludes.
