NTC-14.61.B “Throttling. Gas Flow in a Convergent Nozzle. Gas Flow in a de Laval Nozzle”

Structurally, the stand consists of three parts:

• basis-stand;
• compressor;
• a set of interchangeable devices.

The basis-stand includes:

• power mains input unit with short circuit protection and zero protection;
• measuring system unit;
• compressor control unit;
• air flow meter;
• ambient temperature sensor;
• pressure sensors.

The front panel is made of composite material. The schemes on the front panel are UV-printed and is resistant to mechanical and other influences. The front panel features:

• stand power controls;
• controls of operating actuators;
• connectors for measuring circuits of plug-in modules;
• USB port for connecting a measuring system to a PC.

The mounting area allows quick replacement of the studied plug-in modules. The mounting area features:

• input pressure regulator;
• input pressure gauge.

The output of the pressure regulator features a quick-disconnect connection. which allows quick connection of the studied modules without special tools.

The training system is accompanied with

• a set of teaching materials and technical documentation intended for the teaching staff;
• software with opportunity to display measured values at computer screen in real time and to automate the process of data logging. For each laboratory experiment, a special indication profile has been developed that outputs only the values used in the experiment. The software features the ability to copy or save the received data to a file for further value dependency graphs plotting in Microsoft Office Word or Microsoft Office Excel.
