为了研究稳态边界条件下大型客机座舱内空调通风气流组织分布,利用一架退役但功能完备的全尺寸真实MD-82型飞机建立了一个座舱空气环境实验测量平台.设计了恒温地面式空调机组为飞机座舱输送空调新风,该机组送风参数满足乘客热舒适性要求并保持恒定,同时飞机蒙皮外表面覆盖两层闭孔海绵保温材料,避免大气温度及太阳辐射对机舱内壁面温度的影响.设计了一套发热假人模型系统,用于模拟座舱真实人体散热情况下的空调工况.利用热球风速仪和超声波风速仪测量了机舱送风速度边界,利用标准水银温度计和热成像仪拍摄获得机舱热边界,为CFD模拟提供精确的边界条件.对送风条缝测量发现,机舱送风非常不均匀.
In order to study the tissue distribution of air conditioning ventilation in large passenger aircraft cockpit under steady-state boundary condition, a cockpit air environment experimental measurement platform was established with a retired but fully functional full-scale real MD-82 aircraft.The design of a constant temperature surface air conditioning unit Air-conditioned fresh air is delivered to the cockpit of the aircraft, the air supply parameters of the aircrew meet the passenger thermal comfort requirements and remain constant, while the outer surface of the aircraft skin is covered with two layers of closed-cell sponge insulation material to avoid the influence of atmospheric temperature and solar radiation on the temperature of the inner wall of the cabin A set of heating dummy model system was designed to simulate the condition of air conditioning in the case of real human body cooling.Using the thermo ball anemometer and the ultrasonic anemometer to measure the air supply speed boundary in the cabin and using standard mercury thermometer and thermal imager Filmed to obtain the thermal boundaries of the cabin, providing accurate boundary conditions for CFD simulations. The airbag seam measurements found that the cabin air supply is very uneven.
