“…For instance, studies [8][9] have explored the fundamental principles of charged exhaust particles and electrostatic sensing, leading to the development of probetype electrostatic sensors. Research by [10] delves into the optimization of different types of electrostatic sensors, sensitivity modeling, and the design of planar array electrostatic sensors, enabling the monitoring of abnormal particles and their locations. However, the current state of aircraft engine exhaust particle monitoring techniques using electrostatic principles presents certain challenges.…”

Aircraft engines, serving as the power core of aircraft, also constitute a significant source of potential malfunctions. The charge level of exhaust particles from aircraft engines serves as a crucial indicator of engine malfunction severity. This paper introduces a method for estimating the charge of exhaust particles based on electric field detection to monitor charged particles in the exhaust of aircraft engines. Initially, a mathematical model for estimating the charge of exhaust particles based on Gauss’s theorem is presented. Subsequently, an exhaust electric field induction device is designed, and the distribution of electric field sensors is studied, providing an overall design for the exhaust particle charge measurement system. Finally, the proposed method for estimating the charge of exhaust particles is analyzed through finite element simulation. The results indicate that the introduced aircraft engine exhaust particle charge estimation method based on electric field detection exhibits high accuracy and effectiveness. It offers a novel means for monitoring engine operation faults in aviation, with the potential for application in engine ground testing to further investigate engine state characterization technologies based on exhaust particle monitoring.

<abstract> <p>Renewable energy is a global energy system that is very important in nature and humans' harmonious and conducive development. Considerable attention from the government towards renewable energy is due to the increasing energy demand. The impact of the current energy shortage has also resulted in damage to the environment. The current legal framework for accelerating the development of renewable energy has made a considerable contribution but is still not in favor of investors. Thus, the integration of renewable energy into the national energy system is still far from being expected, so the cooperation between the government and industrial development must be further enhanced. The specific aim of this work is to adopt various practices and policies towards the development of renewable energy from several developing countries. A critical review of this work will discuss policies and legislation on renewable energy policies especially under-operation, fragmentation, and obsolescence. Policies in favor of renewable energy developers are also presented in this paper. This paper as a whole investigates various renewable energy development policies from developing countries to be adopted in ensuring the availability of energy security in the future.</p> </abstract>
