Japan Wind Tunnel Manufacturing Inc.（株式会社日本風洞製作所） Product Lineup

- Short-distance and Marathon In fields such as short-distance running and marathons, which appear to be relatively low-speed and less affected by air, records are considered "wind-assisted" in official competitions and do not count as official results. Our company has also conducted tests on tailwinds, and measurable effects have been observed. We are capable of producing wind tunnels that can reach far with a large area of wind. We can provide an environment where measurements can be taken in a spacious setting (including outdoors). - Racing Wheelchairs As the speed of racing wheelchairs has increased in recent years, there is a trend towards considering aerodynamics in vehicle shapes, clothing, and helmets. Our company has the unique achievement of producing a "dedicated scale for racing wheelchairs." This technology can also be applied to other fields (marathon and short-distance). - Head Measurement Platform Our company manufactures head measurement platforms. They allow for adjustments in yaw and pitch, enabling measurements to be taken with and without hair, as well as the characteristics of different helmets.

• Thermo-fluid analysis

We can assist with the measurement and imaging of internal flows in the engine room, brakes, batteries, motors, and more. In recent years, due to the shift towards electric vehicles (EVs), the objects that need to be cooled have transitioned from engines and radiators to motors and batteries. Since these parts are installed deep within the vehicle, the design of internal flows within the car has become very important. Our company provides support for such thermal fluid and thermal management using a compact wind tunnel.

• Thermo-fluid analysis software

The strength of our wind tunnel lies in its portability. It is characterized by the ability to conduct tests outdoors in a GPS environment. We can replicate the behavior of drones in a GPS environment. The wind tunnel shown in the photo is made by connecting 12 units of Aero Optim, achieving a wind delivery area of 2.7m x 2.1m with a depth of only 1.4m.

This is an attachment for our company's wind tunnel outlet that generates gusts. While there are variations depending on the size, it can accelerate from 0 m/s to 15 m/s within 0.1 to 1 second, putting a load on the drone. Additionally, the main attraction is that the testing device is portable, allowing it to be taken outdoors for testing in a GPS environment. This enables the reproduction of behavior under GPS conditions.

This product is a set item that utilizes the short overall length of the Aero Optim (stacked wind tunnel) with a variable pitch platform. It can recreate a variety of winds, including winds from directly below, diagonally above, diagonally below, and directly above. It can address issues such as downwash and downburst that are problematic for drones. Additionally, the main attraction is that the testing device is portable, allowing it to be taken outdoors for testing in a GPS environment. It can replicate behaviors in a GPS environment.

A boundary layer wind tunnel is a wind tunnel designed to artificially recreate the wind near the ground (atmospheric boundary layer). Regular wind tunnels produce a "clean wind" with uniform airflow and minimal turbulence. In contrast, a boundary layer wind tunnel replicates the characteristics of actual outdoor wind, such as: - Wind speed decreases closer to the ground - Wind speed increases with height - Sudden changes in local wind direction and speed (turbulence).

Wind tunnel testing equipment has few moving parts it can be operated for a long period with proper maintenance (e.g., the University of Tokyo's 3m wind tunnel has been in operation since 1930). However, if you are concerned about damaging your wind tunnel while trying to fix it, our company can provide skilled staff members with specialized knowledge in aftercare.

The CWT series is a wind tunnel with a modular design, allowing for a single-fan configuration as well as a large multi-fan configuration. The advantages include cost reduction due to mass production effects, low power consumption due to deliberate placement of nozzle and flow straighteners, portability in case of a need for expansion or transportation. The nozzle section is custom-built according to the customer's needs (maximum wind speed, wind speed distribution, turbulence, nozzle dimensions and nozzle height).

This is an automotive wind tunnel scale that achieves high resolution (±0.05% Reading) with a space-saving thickness of only 30 cm. The entire system is composed of modular parts, allowing for easy installation in cases where forklifts cannot be used. It was developed in collaboration with Yamato Scale Co., Ltd., a manufacturer that has handled numerous wind tunnel scales for major automotive manufacturers, and Nishiyama Co., Ltd., a technology development-oriented trading company. The SLIM BALANCE is available for rental at the testing center in Numazu.

The Aero Optim series is a stand-alone wind tunnel unit that consolidates all functions of a wind tunnel (fan, diffusor and rectification) into a 0.7m by 0.7m unit. These units can be combined to form the airflow required for a given test section. A standard wind tunnel is often cost-prohibitive to someone looking into purchasing one for the first time, owing to its large consumption of building space and power, as well as high maintenance fees. The Aero Optim wind tunnel provides a low-cost, space-efficient alternative to those wishing for just enough flow quality to make simply, repeatable tests. 【Measurement Platforms】 For automobiles, bicycles, competitive wheelchairs, 6-axis aerodynamics testing, etc. -Wind Tunnel for Everyone-

**Aero Optim Series** ★For more details, please visit our website★ https://japanfudo.com/product/aerooptim-cell.html The Aero Optim series is a "stackable wind tunnel unit." It consolidates all functions of a wind tunnel (airflow, diffusion, uniformity, rectification) into a unit approximately 70 cm square, allowing for a customizable airflow area by stacking the units as needed. This breaks the traditional image of wind tunnels as "large, high-cost, and high-maintenance" systems, making it accessible for those who previously found wind tunnel experiments out of reach by achieving "compact, low-cost, and low-maintenance" solutions. The quality of the airflow is also sufficient for wind resistance testing. While it is possible to use the basic unit alone, additional options can enhance flow quality, add measurement functions, and allow for individual control of fans. **[Measurement Platforms]** For bicycles, competitive wheelchairs, 6-axis measurement platforms, etc. **[Airflow Related]** Additional rectification sections, contraction unit additions, etc.
