Supersonic wind tunnel experimental device

Supersonic wind tunnel experimental device

Compressed air is rapidly blown from an optional (sold separately) large-capacity compressor and tank into the downstream of the experimental area. The air that passes through the straightening and contraction sections of the wind tunnel supplies stable flows at subsonic, Mach 1.4, and Mach 1.8 to the experimental area. The air that has passed through the experimental area mixes again with the blown air and recirculates. Excess air is discharged from the exhaust filter. The experimental area, measuring 100mm x 25mm, comes with three types of interchangeable liners for subsonic, Mach 1.4, and Mach 1.8. The included model is mounted in the center of the observation window, and experiments are conducted while changing the angle. The pressure at 25 locations in the experimental area is displayed in real-time digitally in four groups, and two Bourdon tube pressure gauges show the pressure from the compressor (sold separately) and the supply pressure to the wind tunnel. *The operating time (approximately 10 to 20 seconds) varies depending on the capacity of the compressed air tank, etc.

Tabletop wind tunnel experimental device

Tabletop wind tunnel experimental device

This open-type suction wind tunnel, despite its compact design, allows for a wide range of experiments related to fluid dynamics. It consists of a large bell mouth with a honeycomb, a two-dimensional converging nozzle, an experimental area (125x125mm), a diffusion section, a protective mesh, a variable-speed fan, and a silencer unit, achieving a flow with minimal turbulence. The included manometers (6 units) and two Pitot tubes positioned before and after the experimental area measure wind speed and the pressure distribution in the wake of the model. The experimental area has four sides made of transparent acrylic panels, with the front and back panels being removable. The device comes with a single force balance measurement system and three types of experimental models (a cylindrical model with pressure holes, a NACA0012 wing model, and a flat plate model), allowing for immediate experiments on drag or lift, as well as pressure distribution experiments around a cylinder. The drag or lift (N) is digitally displayed on the included display unit. Additionally, the single force balance measurement system can be mounted on the underside of the experimental area, enabling the measurement of drag (N) with original test specimens made using a 3D printer or similar methods.

Small Wind Tunnel Experimental Device 305

Small Wind Tunnel Experimental Device 305

This open-type suction wind tunnel can conduct a wide range of experiments related to fluid dynamics while being compactly designed. It consists of a large bell mouth, a two-dimensional nozzle contraction body, an experimental area (305x305x600mm), a diffusion body, a protective mesh, an axial flow fan, and a silencer unit, achieving a flow with minimal turbulence. The control unit (desktop type) regulates the rotational speed of the axial flow fan and controls the flow velocity in the experimental area. The wind tunnel and control unit mounted on a caster-equipped frame are designed to be very compact, making it easy to change their arrangement. Various options can be added according to the experimental purpose. The optional data automatic collection system VDAS (sold separately) can display measurement data in real-time on a computer (sold separately) and can calculate and graph the collected data, facilitating a smooth progression of experiments.

Smoke wind tunnel experimental device

Smoke wind tunnel experimental device

This is a specially designed small wind tunnel to visualize the airflow around a model. The compact device can be demonstrated in various locations, such as classrooms, regardless of the laboratory setting, and can be easily moved and stored when not in use. The airflow moves from the bottom to the top. Air entering from the bottom of the device passes through a converging section and a comb-shaped nozzle, then enters observation ducts illuminated on both sides. The lighting clarifies the streamlines around the model. There is a variable-speed fan at the duct exit, which adjusts the flow rate based on volume. A smoke generator is located at the bottom of the device. Smoke (oil droplets) is produced by heated vegetable oil and carbon dioxide supplied from a cylinder, and is sent to the comb-shaped nozzle. From the comb-shaped nozzle, 23 streamlines are released to observe the airflow around the model.

Flight demonstration wind tunnel testing device

Flight demonstration wind tunnel experimental device

This is a device specially designed to conduct extensive experiments on the takeoff, flight, and landing of aircraft. The aircraft model in the suction-type open wind tunnel consists of two propellers, a main wing with a chord length of 152mm (NACA2412), and a fully movable tail with a chord length of 76mm. Air flowing in from the bell mouth is discharged from the device through a straightening honeycomb, the experimental area equipped with the aircraft, a diffusion body, an axial fan, and a silencing duct. The control wheel located at the front of the experimental area manipulates the tail angle of the aircraft model, while the lever simulating the engine throttle on the right side controls the wind speed within the wind tunnel.
