THE PROJECT

Scheuch COMPONENTS was commissioned the task of supplying the perfect source of wind for a new test bench at the company KTM AG. It opted for a double-flow fan, designed for simulating headwind conditions.

The motorcycles that KTM AG manufactures are subjected to extensive testing before they enter series production. This means undergoing trials out on the racetrack during the development stage, plus endurance tests on a range of different test stands. Two of these test stands were already equipped with double-flow fans from Scheuch COMPONENTS, which use a nozzle to simulate headwind hitting the motorcycle at as much as 100,000 m3/h or 200 km/h.

48-hour endurance tests
In the test stand, the 450 kW motor driving the double-flow fan draws in air that is present in the area and blasts it at the motorcycle over the 48 hours required for the endurance test. A robot simulates the rider during this process, changing speed and switching gears automatically. To add an extra dimension of realism to the results, the test stand features integrated heating and cooling – making it possible to test driving performance in the kinds of conditions that would be found in the blazing heat of the desert or at low winter temperatures. Sensors installed at various points on the motorcycle indicate how much air pressure is being generated and in which areas.
“We are delighted with the double-flow fan from Scheuch COMPONENTS. Working with Scheuch was also a fantastic experience”, says Daniel Farbig, KTM AG Team Leader for engine and vehicle test stands, whose responsibilities in the project included planning the new test stand. Gabriel Schustereder, Project Manager at Scheuch COMPONENTS, adds: “The level of power that the fan delivers means it’s a very large piece of equipment, so the staff at KTM AG weren’t able to fit the whole thing in the test stand. To get round this, the fan was split into two parts initially and then reassembled on site. As well as this, the first of the four side panels wasn’t attached until the fan was in its final position”.

OUTSTANDING INNOVATION FROM TWO LONG-STANDING INNVIERTEL COMPANIES

Leonhard Zeilinger, Head of Sales at Scheuch COMPONENTS, is also delighted to have worked with KTM on this project: “It’s a shining example of two long-standing Innviertel companies getting together to create something great. Both companies are amazingly innovative, something that is evident not only in the fan we supplied and KTM’s fantastic products, but also in the professionalism that everyone working on the project showed”.
