Introduction

• The SciSmart-Tunnel is an enhanced version of the original SmartTunnel. It is a fully computerized wind tunnel that uses a patent-pending 3DoF electro-mechanical measurement unit. It has an integrated pitot tube for true air speed measurement. It has a stronger impeller to generate higher air speeds of up to 15m/s (55kph). It includes an air flow straightener to produce more accurate measurements. Like the Smart -Tunnel, the mechanical structure is lightweight and foldable for easy storage or relocation. In addition,  the entire operation is done remotely using a standard PC with user-friendly application.

Modes of operation 

The SciSmart-Tunnel is fully operated from a remote computer and can be programmed to perform different test profiles automatically. It can be operated in two ways:

Manual: The user sets the Angle Of Attack (AOA) and air speed. After the desired test conditions settled, the user command a measurement operation to display and log the applied forces that acts on the test model. Each measurement includes its statistical properties (Mean and Stddev) and logged into a CSV file for later analysis.

Automatic: The user setup and load a predefined test protocol that includes AOA and air speeds. The wind tunnel follow the profile and dwell at each test point before logging a measurement. At the end, a graphical representation can be generated.

Performance

• Accurate 3DOF measurements of drag, lift, and pitch-moment forces.

• Measurement crosstalk: roll torque will affect lift and yaw torque will affects drag measurement.

• Maximum force: 8[N] (800gr), Resolution: 0.01[N] (1gr), Accuracy 0.02[N] (2gr)

• Maximum torque: 100[N*mm], Resolution: 0.3[N*mm], Accuracy 1[N*mm]

• Maximum wind velocity: 14[m/s] (50kph), Wind velocity resolution 0.5[m/s]

• Maximum UUT AOA: -45deg to 45 deg, AOA resolution: 1deg (accuracy <1deg)

• Power consumption: 600w (AC220v / AC110v / DC-12v)

• PC communication: USB or RS232
