ORIX Rentec Commences Offering of One-Stop Wind Tunnel Test Solution Service for Designing and Modelling of Mock-Ups and Aerodynamic Analyses

TOKYO, Japan - October 4, 2022 - ORIX Rentec Corporation (“ORIX Rentec”) announced today that it would offer a new Wind Tunnel Test Solution Services using 3D printers jointly with Persol Research & Development Co., Ltd. (“Persol R&D”).

Wind tunnel tests are generally conducted in the course of developing new models of automobiles or railroad cars to improve their aerodynamic characteristics. The concept is that identifying various effects of the flow of surrounding air on a moving vehicle will help optimize its shape and structure and thereby improve its fuel efficiency and operating performance.
The Wind Tunnel Test Solution Service covers three steps. First, Persol R&D designs the 3D data of a mock-up^*1 required for wind tunnel tests. ORIX Rentec then fabricates the mock-up with a 3D printer. Finally, Persol R&D carries out wind tunnel tests and aerodynamic analyses of the mock-up. As the wind tunnel test is contracted as a one-stop service, customers do not have to find other outsourcing companies or subcontracting firms for the respective processes. This allows them to hold fewer meetings and seek fewer quotations. Changing the shape of the mock-up and conducting retests can also be handled quickly.

Transportation equipment, including automobiles and railroad cars, are required to contribute toward achieving targets of carbon neutrality by 2050 with reduced environmental loads. The automobile sector accounts for about 15% of the domestic CO₂ emissions in Japan^*2. Heavy vehicles such as buses and trucks must meet the fuel efficiency standards by 2025 (target fiscal year) and passenger vehicles including electric vehicles and plug-in hybrid cars must meet similar standards by 2030 (target fiscal year) as stipulated in the Act on the Rational Use of Energy (“Energy Saving Law”)^*3. Besides fuel shift such as to electric vehicles (EV), other pressing issues include improvement of fuel efficiency performance such as through aerodynamic improvement.

ORIX Rentec will contribute to the reduction of CO₂ emissions in a wide range of fields—including automobiles and ultrasmall mobility, railroad, ships, aerospace, and drones—by improving the precision of wind tunnel tests.

*1 A mock-up is a model that is fabricated in the design stage of an industrial product and whose appearance is close to that of the finished product.
*2 Data from the document “CO₂ Emissions from Transport Industries” (Ministry of Land, Infrastructure, Transport and Tourism)(in Japanese)
*3 See the documents “Fuel efficiency standards have been formulated for heavy vehicles that are to be met by fiscal 2025” (Ministry of Land, Infrastructure, Transport and Tourism) and “Fuel efficiency standards for passenger vehicles have been formulated for fiscal 2030” (Ministry of Land, Infrastructure, Transport and Tourism)(in Japanese)
