Abstract
The nacelle lip skin is a critical component in aircraft design that has a major impact on aerodynamic efficiency and overall engine performance. The analysis of de-icing technology is very important because the formation of ice on the nacelle lip skin poses a serious risk to flight safety. Uneven temperature distribution can lead to re-ice formation, where melting ice refreezes downstream, creating additional hazards. This final year project (FYP) focuses on the investigation of the temperature distribution on the nacelle lip skin during the operation of the hot air de-icing system. The main objective is to develop an experimental setup that can simulate the real conditions faced by an aircraft nacelle and analyse the heat is distribution across the nacelle lip skin. The hot air heater in this arrangement is designed to supply air at a temperature between 45℃ to 55℃. Preliminary findings from experiments show that the uniformity of heat distribution is affected by factors such as air flow rate, supplied air temperature, and nacelle lip skin geometry. This research emphasizes the importance of optimizing these parameters to increase the effectiveness of the de-hazing system. This study contributes to the knowledge of the principles of heat transfer. It provides room to improve NextGen aircraft to handle icing conditions better, as shown by the increase in the average dimensionless temperature from 0.247 to 0.368 under varying Reynolds numbers, thus helping the aviation industry towards its goal of improving operations reliable aircraft in bad weather. The results of this study are expected to contribute to the development of a more effective anti-hazing system for aircraft. This research, with its detailed analysis of the temperature distribution and critical factors of de-icing system performance, offers valuable insights that help engineers and researchers improve design and operational strategies, as well as flight safety and efficiency.
