Supporting a state-of-the-art crosswind simulation facility with innovative solutions
Systemair delivered 15 jet fans to Robert Bosch GmbH's test centre ensuring successful integration from the outset through strong collaboration.
Robert Bosch GmbH test centre, Germany
Strong cooperation and meticulous planning
The project benefited from a successful and collaborative approach supported by strong preliminary planning.
Innovative solutions
The Systemair jet fans met the customer's specific requirements for their crosswind sensitivity test procedures, with integrated silencers providing a significant advantage in terms of noise level.
Full flexibility of the generated wind power and technical control
The 15 jet fans installed can be selected depending on the desired test scenario and have a minimum speed of 40%, enabling the customer to run various crosswind scenarios and control and monitor everything from a central control room.
Expertise supporting successful commissioning of the fans
In addition to the fans, Systemair also provided Robert Bosch GmbH with all the expertise they needed. The fans were successfully integrated into the crosswind simulation system from the onset, which was challenging given the technical complexity.

Supporting a renowned testing centre
The Bosch test centre in Boxberg, Germany, spans 97 hectares and features numerous test tracks dedicated to testing and developing vehicles and systems. The facility is renowned for its work on complex vehicle systems, notably the Electronic Stability Programme (ESP). Bosch continuously optimises the ESP and its various functions, including Crosswind Assist, by utilising sensors installed in vehicles and their braking systems. This technology intervenes early during driving to mitigate the impact of crosswinds on the vehicle. A major customer of the test centre is increasingly implementing crosswind assistants in the passenger car sector.
Principle of the test procedure
The test procedure makes it possible to investigate the behaviour of vehicles and their control systems in response to external disturbances. Under the influence of a crosswind, forces act on a vehicle that can cause a change in direction and a course offset. The extent of the disturbance and the control effort required by the driver to compensate for the vehicle's reactions are then evaluated. In addition, the approach routes are also tested with different scenarios: with different motorisation, fully loaded, and trailer operation. The test sequences also test new modes of use with motorbikes, buses and lorries.
Therefore, the test facility must offer ideal conditions for evaluating crosswind behaviour and sensitivity in vehicles.

Full flexibility and control
To meet the requirements of the crosswind simulation facility, Systemair supplied 15 AJ 1250 / 55 kW jet fans, each equipped with integrated silencers for a powerful solution. These fans were expertly installed side by side and commissioned at the 2023 test site, which features a dedicated 30-meter measuring section.
Initially designed for the ventilation of construction sites, these jet fans offer versatile operation options tailored to various test scenarios. They can be activated individually, in groups, or as an entire row. With a minimum speed setting of 40%, these jet fans allow the customer to simulate diverse crosswind conditions. All operations are centrally controlled and monitored from a control room, ensuring precise management of the testing environment.
Due to our increasing need for test scopes, we have chosen Systemair because, on the one hand, we were convinced by the performance of the jet fans with silencers and, on the other hand, the cooperation with Arthur Palmer was very trusting and constructive. We were in constant contact with each other and optimised the route, the access routes and the wind speeds. The system worked well straight away!
Project Manager and Engineering Service Boxberg
Our motto is ‘Testing, but always with safety as a priority. ' That's why the management of the test track is completely focused on safety aspects. For me, the cooperation with Systemair is an all-around great project, also for Boxberg! There is a synergy effect!

Celebrating a successful collaboration
Recently, the Systemair team, including project manager Arthur Palmer, took the opportunity to visit the Robert Bosch GmbH test centre in person and experience the crosswind simulation system in action on-site following the successful completion of the project. Tests were carried out using the example of a small van driving past.
Arthur Palmer expressed his thanks to site manager Joachim Schorr, project manager Markus Rheinhold, and their entire team for the invitation to exchange ideas.
