Abstract�� A full-scale experiment was carried out on air flow and heat transfer of a fight plane-s cockpit. Aerothermal load and body heat load were simulated, and ATM2400 36-channel airflow and temperature instrument were used to measure velocity fields of 5 measurement planes and temperature fields of 2 measurement planes and near clothing surface. The influnce of air supply flux and the switch of nozzles was observed, and the cockpit comfort was assessed. The results show that velocity fields are asymmetry and temperature distribution on cockpit-s inside wall is unevenness, and the switch of nozzles has great effect on velocity fields, temperature fields and temperature distribution near clothing surface while has little effect on the average velocity and temperature in cockpit, and the average velocity is linear with air supply flux. Experimental results can be used for proving numerical simulation accuracy.
Keywords�� cockpit   air distribution system   velocity field   temperature field   heat load   comfort
