Semi-transparent simulation experiment platform of large passenger plane cabin environment

Abstract

The invention discloses a semi-transparent simulation experiment platform of a large passenger plane cabin environment. The semi-transparent simulation experiment platform comprises a thermostatic chamber, a thermostatic chamber air conditioning system, a simulation cabin air conditioning system and a real-time data acquisition and monitoring system, wherein a semi-transparent simulation cabin of the passenger plane cabin environment is arranged in the thermostatic chamber. The semi-transparent simulation cabin and seats in the semi-transparent simulation cabin are all designed and installed according to a real cabin size with the ratio of 1:1. Thermal manikins are arranged in the simulation cabin and used for simulating sensible heat and heat dissipation of real persons. The simulation cabin is provided with multiple types of simulation air ports, and disassembling and replacing are convenient. Air distribution forms of the simulation cabin can be changed by opening or closing a valve. By utilizing the air conditioning system of the thermostatic chamber and the air conditioning system of the simulation cabin, diversified experimental conditions can be achieved. Through a computer software platform, real-time data can be monitored and controlled. According to the semi-transparent simulation experiment platform, a flow field in the cabin can be obtained by fully utilizing a PIV technology, and meanwhile the diversified cabin air distribution forms can be achieved. The working condition during the experimental process is stable, and regulating and controlling of temperature and air output are accurate.

Description

technical field [0001] The invention relates to the experimental research on the cabin environment of a passenger aircraft, and in particular to related experimental researches on the characteristics of airflow organization in the cabin of a passenger aircraft, the transmission of pollutants, and the thermal comfort of passengers. Background technique [0002] With the development of science and technology and civil aviation, passenger aircraft, as a means of transportation that provides high-speed and fast public transportation services, has gradually become a popular way of travel. At present, more than 2 billion people around the world choose to travel by air every year, and this number will continue to increase. As the number of air passengers continues to increase, so will the problems posed by flying. International flights have greatly increased the chances of rapid international spread of infectious diseases. The World Health Organization (WHO) pointed out that SARS ...

AI Technical Summary

Problems solved by technology

However, there are certain defects in the application of these simulation cabins: (1) The outer walls of most simulation cabins are opaque, and only embedded flow field measurement tools (ultrasonic anemometer, etc.) influences

(2) Non-embedded particle imaging velocimetry (PIV) can be applied to partially transparent simulation cabins, but its measurement area is generally limited obviously, and it is basically an empty cabin without thermal mannequins and seats

(3) The existing simulation cabin is only designed for a certain aircraft type, and it is impossible to conduct comparative studies on the airflow organization forms in the cabins of different aircraft types

(4) The existing cabin simulation experiment platform does not consider the precise control of the external environment of the simulation cabin, and the stability and controllability of the boundary conditions are low
