ZF1129A Air Flow Training Unit Fluids Engineering Training Equipment Teaching Equipment Didactic Equipment1. Equipment introduction
1.1 Overview
Aerodynamics is a branch of mechanics that studies the force characteristics of aircraft or other objects in relative motion with air or other gases, the flow patterns of gases, and the accompanying physical and chemical changes.
There are two classification methods for aerodynamics: (1) According to the speed range of fluid movement or the flight speed of the aircraft, aerodynamics can be divided into low-speed aerodynamics and high-speed aerodynamics. Usually, the speed of 400 kilometers per hour (this value is close to the value of 0.3Ma at 1atm on the ground and 288.15K) is used as the dividing line. In low-speed aerodynamics, the gas medium can be regarded as incompressible, and the corresponding flow is called incompressible flow. (2) Depending on whether the viscosity of the gas medium must be considered in the flow, aerodynamics can be divided into ideal aerodynamics (or ideal gas dynamics) and viscous aerodynamics.
The ZF1129A airflow trainer is a device used to study aerodynamics. It can study viscous and low-speed aerodynamic theories. The device is mainly composed of two parts. One part is the main part of the device, which mainly provides the high-speed flow of air required for experiments; the other part is the accessories library of the device, which is mainly used to verify various experiments. .
1.2 Features
(1) Adopting a safer electrical design, the device has excellent and reliable grounding performance.
(2) An integrated electrical solution is adopted, which can clearly display the various sensor data obtained through the smart display, allowing users to process the data more conveniently.
(3) The device provides many various experimental accessories, and the experiments that can be performed are becoming more and more abundant.
(4) Using corrosion-resistant and stronger materials, the equipment has higher safety and longer service life.
