Airborne nitrogen inerting is the most ideal way to suppress the explosion of aircraft fuel tanks, and hollow fiber membrane inerting is the most economical and efficient airborne nitrogen inerting technology. The size of the membrane core in the hollow fiber membrane module determines the nitrogen production performance, and also determines the space size and weight of the module to a certain extent. This paper mainly studies the factors that restrict the size of the membrane core, analyzes the influence of the effective length of the membrane core, the radius of the membrane core and the filling rate on the nitrogen production performance of the module, and gives the calculation method of the nitrogen production performance and quality of the membrane core, and finally obtains the given Optimal solution for spatial membrane core size. The research results can provide a reference for the subsequent optimization design of the hollow fiber membrane size. © 2022 IET Conference Proceedings. All rights reserved.

As one promising sensorless control algorithm, the nonlinear flux observer is widely used in industries. However, it is sensitive to parameter variations and the gradient search gain can greatly affect its stability. Therefore, this paper proposes an improved nonlinear flux observer, which corrects the stator flux estimation by adding an extended state observer (ESO) to reduce the parameter sensitivity. In addition, the position error compensation is realized by another ESO constructed in estimated rotation frame. The effectiveness of the proposed algorithm is verified experimentally. © 2024 The Institute of Electrical Engineers of Japan.

Lamb waves, characterized by slow attenuation, short wavelength, and sensitivity to damage, have been widely utilized in the field of composite material damage detection. In addressing the issue of damage localization in composite curved tank structures, this study proposes a composite tank localization algorithm based on convolutional neural networks (CNNs) using Lamb wave data. The approach transforms the damage localization regression problem into a classification problem through partitioning, achieving damage zone localization in composite tank structures with fewer sensors. The accuracy of the algorithm is more than 98% in the dataset constructed from physical experiments, which verifies its accuracy and applicability. © The Institution of Engineering & technology 2024.

In this paper, two key components of thermal management system are modeled by the underlying logic operation of SIMULINK. Simulink-PS signal conversion module is used to connect the electric grid and the calculation part of the heat grid to build the fuel tank heat grid model. The temperature transient simulation model of phase-change heat exchanger was established by using the integral module in Simulink library. Experimental verification and literature data verification are provided for these two components. The results show that the error between simulation results and experimental data is between 0.1% and 3%, which proves the accuracy and feasibility of the system modeling in this paper. It lays a foundation for the simulation of the overall thermal management scheme. © The Institution of Engineering & technology 2024.

Valve is important flow control part in the flow tube system, which is defined by the valve plate angle characters, many researches had been done to get valve plate characters by tests and numerical simulations. Function (1) is famous formula to estimate valve characters, such as mass flow, pressure drop, and so on, where μis a key parameter to calculate. The data of test and simulation of data from reference [4] and reference [9] had dealt by function (2), which had shown that the μhad some bigger than 1 values, the angle of valve open and the pressure ratio had established μtogether. The bigger than 1 values had been gotten by same conditions, which derived from mouth type nozzle inducing injecting.

The motor for electromechanical actuator has high reliability requirements. This paper studies a triple redundancy permanent magnet synchronous motor with winding redundancy structure. However, the triple redundancy system has the problem of asymmetric channel parameters, which leads to unbalanced winding phase current and affects the reliability of the triple redundancy permanent magnet synchronous motor. In this paper, the possible consequences of parameter asymmetry are analyzed. Aiming at the problem of stator current imbalance caused by parameter asymmetry, a cooperative control strategy based on virtual impedance is proposed. The control strategy compensates the parameters through the virtual impedance adjustment module, which can reduce or even eliminate the parameter asymmetry and realize the balanced control of the winding phase current. At the same time, a Simulink model is built to verify the effectiveness of the control algorithm. Finally, the hardware drive platform and software control algorithm based on YXSpace 2000 semi-physical simulator are built for experimental verification. © 2023 IEEE.

This paper takes the aviation Electro-hydrostatic Actuator (EHA) as the research object, analyses its working principle and structural characteristics, establishes mathematical models for the drive motor, pump and cylinder, and builds a simulation model based on MATLAB/Simulink. Addressing the issues of strong nonlinearity, cumbersome manual tuning of PI parameters under strong disturbances, and poor control effects in the EHA systems, this paper proposes an auto-tuning method for PI control parameters based on improved Bayesian optimization. A comparative analysis is conducted with traditional manual tuning methods and RF methods. According to simulation comparison results, the proposed method outperforms traditional tuning methods in terms of robustness and rapidity.

Unmanned aerial vehicles (UAVs) have enabled the unmanned management of water areas. Path loss (PL) serves as a critical factor that affects the UAV communication quality. In this work, a PL model for UAV channel in water scenarios is proposed, aiming to explore the multidimensional relationship between transceiver distance, carrier frequency, UAV height, and PL by constructing an Artificial Neural Network (ANN). Moreover, channel measurements are conducted in a river area, and the obtained data are analyzed using the proposed ANN model as well as the close-in (CI) model. The analysis results demonstrates that the PL increases initially and then declines as the UAV height increases. The proposed ANN model has higher prediction accuracy than the classic empirical model, and can achieve precise prediction of the PL in water scenarios. © 2024 IEEE.

The reliability requirements of the aviation electromechanical actuator system are high, and the three-redundancy motor is often used to provide reliable propulsion power. The triple-redundancy PMSMs is composed of a nine-phase stator winding and a permanent magnet rotor. When a redundancy fails, the fault redundancy is actively removed, and the use of other redundancy can still maintain the normal operation of the system to ensure that the entire system can maintain normal operation. However, the traditional 3-dq modeling method ignores the mutual inductance and flux linkage coupling between different windings, and it is difficult to achieve a smooth transition of redundancy removal. The purpose of this paper is to propose a decoupling control method for multi-stator modeling, which eliminates the cross-coupling of mutual inductance between redundancy and retains the modular control characteristics of 3-dq decoupling. When one or two redundant faults occur, the fault winding is actively removed to reduce the dynamic transition time of speed and torque during redundancy switching and realize the smooth transition of fault winding removal. © 2023 IEEE.

The plunger pump is one of the most complicated hydraulic components, the fault reason is hidden, the traditional analysis method such as theoretical formula is difficult to study its fault principle and correlation. In some cases of plunger pump failure, the fracture of the plunger is usually accompanied by serious wear of plunger and sliding shoe. In order to study the correlation between kinematic pairs wear and plunger fracture, a flexible-solid coupling dynamic digital prototype of plunger pump is built, which takes into account the action of hydraulic pressure and rotating load in a rotating cycle. The friction force of the friction pair is considered by modifying the contact method of the friction surface of kinematic pair. The simulation results show that the plunger pair wear leads to the increase of supporting force of sliding shoes, the wear of plunger and sliding shoe leads to the sharp increase of stress of plunger neck, the wear of kinematic pair is related to the plunger fracture.
