“…The pneumatic inflatable boot (PIB) is a mechanical deformation ice protection device commonly used in light airplanes. The development of the inflatable boot began in 1928, and this has been used in more than 30,000 small aircraft worldwide (Ramamurthy et al, 1991). This device has inflatable rubber strips on the wings' outer surface and control surfaces where ice is accreted (Ronaudo et al, 1991).…”

Aircraft icing remains a key aviation hazard as the global fleet of aircraft in various sectors continues to expand, posing a serious threat to flight safety. As previously stated, the growth of this type of aircraft has been accompanied by an increase in noise levels, and aircraft is reportedly the second most bothersome noise source after traffic. However, integrating an acoustic liner with anti-icing techniques on the leading edge of a nacelle would not efficiently eliminate forward radiated noise and improve the thermal performance of the anti-icing system. Hence, it is of the utmost importance to research the integration of ice protection and noise abatement systems for aircraft applications. This review discusses the integration of ice accretion and noise abatement systems in aircraft applications. The prominence of this review is to explain significant features such as ice protection systems, Computational Fluid Dynamics in ice protection, noise abatement systems, and the integration of ice protection systems and noise abatement systems wherever they are described.

“…Due to the combination of shear, bending, and peel forces, the surface distorts and breaks the ice down. Then the broken ice is carried away from the surface by aerodynamic force (Ramamurthy et al, 1991). The working principle of the pneumatic inflatable boot is shown in Figure 1.…”

“…Before entering conditions that can lead to icing, anti-icing mechanisms are activated and are intended to stop ice formation while continuously providing energy. Conversely, de-icing systems are usually used to remove ice that regularly accumulates to a considerable thickness [7,[9][10][11][12]. Anti-icing bleed air technology is widely used in the aircraft industry [13,14].…”

Airplane manufacturers are frequently faced with formidable challenges to improving both aircraft performance and customer safety. Ice accumulation on the wings of aircraft is one of the challenges, which could result in major accidents and a reduction in aerodynamic performance. Anti-icing systems, which use the hot bleed airflow from the engine compressor, are considered one of the most significant solutions utilized in aircraft applications to prevent ice accumulation. In the current study, a novel approach based on machine learning (ML) and the Internet of Things (IoT) is proposed to predict the thermal performance characteristics of a partial span wing anti-icing system constructed using the NACA 23014 airfoil section. To verify the proposed strategy, the obtained results are compared with those obtained using computational ANSYS 2019 software. An artificial neural network (ANN) is used to build a forecasting model of wing temperature based on experimental data and computational fluid dynamics (CFD) data. In addition, the ThingSpeak platform is applied in this article to realize the concept of the IoT, collect the measured data, and publish the data in a private channel. Different performance metrics, namely, mean square error (MSE), maximum relative error (MAE), and absolute variance (R2), are used to evaluate the prediction model. Based on the performance indices, the results prove the efficiency of the proposed approach based on ANN and the IoT in designing a forecasting model to predict the wing temperature compared to the numerical CFD method, which consumes a lot of time and requires high-speed simulation devices. Therefore, it is suggested that the ANN-IoT approach be applied in aviation.
