TAS25/100C Computer Controlled Supersonic Wind Tunnel





The Computer Controlled Supersonic Wind Tunnel, "TAS25/100C", is an open wind tunnel for the study of the aerodynamic properties of different drag bodies subject to subsonic and supersonic flows. Air flows through a vacuum pump or blower incorporating a computer controlled power regulator, located on the discharge side of the tunnel.

The air enters the tunnel through a nozzle, which has a flow rectifier where the fluid is accelerated. Then, the transparent working section is located, which consists of a section where the resistance models are mounted, and the accelerated air flows around these models. The models included have different forms: rocket, projectile, wedges of different slops and double wedge with different inclinations.

There are three different upper profiles of the working section to generate different velocities up to two times the speed of sound (2 Mach).

The optional "TAS25/100-SO" accessory, an optical Schlieren system, allows you to directly observe and photograph the supersonic flow and shock fronts formed around the aerodynamic models, thus enabling a greater number of experiments.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
