    1-22页
    查看更多>>摘要：Fatigue properties of materials by Additive Manufacturing(AM)depend on many fac-tors such as AM processing parameter,microstructure,residual stress,surface roughness,porosi-ties,post-treatments,etc.Their evaluation inevitably requires these factors combined as many as possible,thus resulting in low efficiency and high cost.In recent years,their assessment by leverag-ing the power of Machine Learning(ML)has gained increasing attentions.A comprehensive over-view on the state-of-the-art progress of applying ML strategies to predict fatigue properties of AM materials,as well as their dependence on AM processing and post-processing parameters such as laser power,scanning speed,layer height,hatch distance,built direction,post-heat temperature,etc.,were presented.A few attempts in employing Feedforward Neural Network(FNN),Convolu-tional Neural Network(CNN),Adaptive Network-Based Fuzzy Inference System(ANFIS),Sup-port Vector Machine(SVM)and Random Forest(RF)to predict fatigue life and RF to predict fatigue crack growth rate are summarized.The ML models for predicting AM materials'fatigue properties are found intrinsically similar to the commonly used ones,but are modified to involve AM features.Finally,an outlook for challenges(i.e.,small dataset,multifarious features,overfitting,low interpretability,and unable extension from AM material data to structure life)and potential solutions for the ML prediction of AM materials'fatigue properties is provided.

    54-92页
    查看更多>>摘要：High-performance devices usually have curved surfaces,requiring high accuracy of shape and low surface roughness.It is a challenge to achieve high accuracies for form and position on a device with low surface roughness.However,due to the unique nonlinear rheology,magnetorheo-logical fluids with hard abrasives are widely applied in ultra-precision surface finishing.Compared with conventional mechanical finishing,magnetorheological finishing displays obviously advan-tages,such as high precision shape of machined surface,low surface roughness and subsurface dam-age,and easy control for finishing processes.However,finishing performance depends on various factors,e.g.volume fraction and distribution of magnetic particles,types of hard abrasives and additives,strength of magnetic field,finishing forms.Therefore,a comprehensive review on related works is essential to understand the state-of-the-art of magnetorheological finishing and beneficial to inspire researchers to develop lower cost,higher machining accuracy and efficient approaches and setups,which demonstrates a significant guidance for development of high-performance parts in fields of aerospace,navigation and clinical medicine etc.This review starts from the rheological property of magnetorheological fluids,summarizing dynamically nonlinear rheological properties and stable finishing approaches.Then,the effect of components in magnetorheological fluids is dis-cussed on finishing performance,consisting of magnetic particles,carrier fluid,additives and abra-sives.Reasonable configuration of magnetorheological fluids,and different magnetorheological finishing methods are presented for variously curved surfaces.In addition,the current finishing forms and future directions are also addressed in this review.

    93-120页
    查看更多>>摘要：Fault diagnosis plays a significant role in conducting condition-based maintenance and health management for gas turbines(GTs)to improve reliability and reduce costs.Various diagno-sis methods developed by modeling engine systems or certain components implement faults detec-tion and diagnosis based on the measurement of systemic parameters deviations.However,these conventional model-based methods are hindered by limitations of inability to handle the nonlinear nature,measurement uncertainty,fault coupling and other implementing problems.Recently,the development of artificial intelligence algorithms has provided an effective solution to the above problems,triggering broad researches for data-driven fault diagnosis methods with better accuracy,dynamic performance,and universality.This paper presents a systematic review of recently pro-posed intelligent fault diagnosis methods for GT engines,according to the classification of shallow learning methods,deep learning methods and hybrid intelligent methods.Moreover,the principle of typical algorithms,the evolution of enhanced methods,and the assessment of pros and cons are summarized to conclude the present status and look forward to the future in the field of GT fault diagnosis.Possible directions for development in method validation,information fusion,and inter-pretability of intelligent diagnosis methods are concluded in the end to provide insightful concepts for scholars in related fields.

    An integrative mathematical model of microwave ion thruster for mHz-frequency thrust noise analysis

    Xiang NIUHui LIUDaren YU
    121-136页
    查看更多>>摘要：Many high-precision space missions need thrusters to produce thrust with low noise to compensate for disturbances and ensure satellite platform stability.Microwave ion thruster is char-acterized with a wide thrust range and potential for these missions.A cost-effective and accurate mathematical model is crucial for mHz-frequency thrust noise analysis and feedback controller design.The Particle-In-Cell(PIC)and global models are two common simulation tools.The PIC model is characterized with high accuracy but huge computation cost,which is difficult to analyze long-time performance characteristics.Now,the global model is only used for the discharge cham-ber with low accuracy and cannot reflect ion extraction properties.In this paper,an integrative mathematical model is built for a 1-cm microwave ion thruster and can reflect ion beamlet diver-gence and impingement on the Accelerator Grid(AG).Simulation results show good agreement with experiments at 0.06 sccm.However,the model demonstrates worse consistency with experiments when the flux increases to 0.1 sccm,which may be because the influence of neutral gas on the Electron Cyclotron Resonance(ECR)is not considered in the model.A long-time(1000 s)simulation is conducted with this model under 35 μN.It takes 3 hrs,and the thrust noise reaches 1 μN/Hz0.5 at 1 mHz.

    Infrared radiation characteristics of dagger-type hypersonic missile

    Xubo DUQingzhen YANGHaoqi YANGJin BAI...
    137-150页
    查看更多>>摘要：Hypersonic vehicles emit strong infrared radiation from their high-temperature exhaust plume and body,which is critical for infrared early warning,tracking,and guidance.In this work,a comprehensive analysis is conducted on the factors involved in air dissociation reaction within the shock layer of hypersonic missile heads,as well as the multi-component afterburning effect of the exhaust plume.A novel Reverse Monte Carlo Method(RMCM)is proposed for infrared radiation calculation,which utilizes two-dimensional Low-Discrepancy Sequences(LDS)to improve compu-tational accuracy.The numerical calculations for a dagger-type missile show that afterburning reac-tions increase the temperature on the centerline of the outlet exhaust plume by about 1000 K.The total infrared radiation intensity of the missile is the highest in the 1-3 μm band,with the high-temperature wall of the nozzle being the primary source of solid radiation,and gas radiation pri-marily coming from H2O.The radiation intensity of the missile exhaust plume in the 3-5 μm band is the highest,with radiation sources primarily coming from CO2,CO,and HC1.Afterburning reac-tions of the exhaust plume increase the total infrared radiation intensity of the missile by about 0.7 times.These results can provide reference for the detection and guidance of hypersonic missiles.

    Experimental study on shock interaction control of double wedge in high-enthalpy hypersonic flow subject to plasma synthetic jet

    151-165页
    查看更多>>摘要：The hypersonic shock-shock interaction flow field at double-wedge geometries controlled by plasma synthetic jet actuator is experimentally studied in a Ma=8 high-enthalpy shock tunnel with the purpose of exploring a novel technique for reducing surface heat flux in a real flight envi-ronment.The results demonstrate that increasing the discharge energy is advantageous in eliminat-ing the shock wave,shifting the shock wave interaction point,and shortening the control response time.The oblique shock wave can be completely removed when the actuator's discharge energy grows from 0.4 J to 11.5 J,and the displacement of the shock wave interaction point increases by 124.56％,while the controlled response time is shortened by 30 μs.Besides,the reduction in diameter of the jet exit is firstly proved to have a negative impact on energy deposition in a working environment with incoming flow,which reduces the discharge energy and hence decreases the con-trol effect.The shock wave control response time lengthens when the jet exits away from the second wedge.Along with comparing the change in wall heat flux at the second wedge over time,the con-trol effect of plasma synthetic jet actuator with and without inflation is also analyzed.When plasma synthetic jet works in inflatable mode,both the ability to eliminate shock waves and the shifting effect of the shock wave interaction point are increased significantly,and the wall heat flux is also reduced.

    Development of a deviation package method for low-cost robust optimization in compressor blade design

    Mingzhi LIXianjun YUDejun MENGGuangfeng AN...
    166-180页
    查看更多>>摘要：Manufacture variations can greatly increase the performance variability of compressor blades.Current robust design optimization methods have a critical role in reducing the adverse impact of the variations,but can be affected by errors if the assumptions of the deviation models and distribution parameters are inaccurate.A new approach for robust design optimization without the employment of the deviation models is proposed.The deviation package method and the inter-val estimation method are exploited in this new approach.Simultaneously,a stratified strategy is used to reduce the computational cost and assure the optimization accuracy.The test case employed for this study is a typical transonic compressor blade profile,which resembles most of the manufac-ture features of modern compressor blades.A set of 96 newly manufactured blades was measured using a coordinate measurement machine to obtain the manufacture variations and produce a devi-ation package.The optimization results show that the scatter of the aerodynamic performance for the optimal robust design is 20％less than the baseline value.By comparing the optimization results obtained from the deviation package method with those obtained from widely-used methods employing the deviation model,the efficiency and accuracy of the deviation package method are demonstrated.Finally,the physical mechanisms that control the robustness of different designs were further investigated,and some statistical laws of robust design were extracted.

    Effects of dynamical spanwise retraction and stretch on flapping-wing forward flights

    Kang LIUBifeng SONGAng CHENZhihe WANG...
    181-202页
    查看更多>>摘要：Birds and bats retract and stretch their wings dynamically during each flap in level flights,implying intriguing mechanisms for the aerodynamic performance improvement of flapping wings.A numerical investigation into the aerodynamic effects of such bio-inspired concept in for-ward flights has been performed based on a three-dimensional wing in plunging motion and a two-section wing in flapping motion.The currently considered Reynolds number and Strouhal number are Re=1.5 × 105 and St=0.3,respectively.During the research,the mean angle of attack is var-ied in relatively wide ranges to achieve lift-thrust interconversion for the wings.The conclusive results show that dynamical spanwise retraction and stretch has induced three absolutely desirable scenarios for the oscillating wings in forward flights,namely producing more lift and consuming less power for a given thrust generation,producing more thrust and consuming less power for a given lift generation,and producing more lift and more thrust while consuming less power.Furthermore,the morphing wings have alleviated periodical aerodynamic load fluctuations compared with the non-morphing baseline.The mechanism of the aerodynamic effects of the bionic morphing mode is analyzed with the aid of field visualization.The current article is the first to reveal the absolute advantages of the bionic spanwise morphing.Hopefully,it may help comprehend the behaviors of natural fliers and provide inspirations for performance enhancement of micro artificial flapping-wing vehicles.

    An axisymmetric characteristic model for enhancing prediction of centrifugal compressor characteristics

    Peng RENXiangjun FANGZeyu JIAOYing HAN...
    203-215页
    查看更多>>摘要：Rapid and accurate determination of compressor characteristic maps is essential for the ini-tial design of centrifugal compressors in aircraft power systems.The accuracy of existing methodolo-gies,which rely on combinations of loss models,varies significantly depending on the compressor's geometry and operational range.This variance necessitates substantial experimental or Computational Fluid Dynamics(CFD)data for coefficient calibration.To address this challenge,this study presents an axisymmetric characteristic model for compressor performance assessment.This model incorporates the factors of blade angle,meridional passage area,and the radial deflection angle of meridional stream-lines of the compressor.These factors are derived from fundamental aerodynamic equations encom-passing mass,momentum,and energy conservation of the compressor.In contrast to conventional one-dimensional approaches,the proposed method reduces the number of loss coefficients and more effectively accounts for the impact of geometric alterations on centrifugal compressor properties.Fur-thermore,the model reduces dependence on experimental and CFD data.Efficacy of the model is val-idated using experimental data from four distinct types of centrifugal compressors.Correlation analysis reveals that the model's coefficients can be expressed as functions of the ratio of the Reynolds number to the impeller tip speed.This ratio serves as a characteristic parameter for the design and optimization of centrifugal compressors.Consequently,the proposed method offers an efficient and accurate means for the quick computation of centrifugal compressor characteristics.This is of great significance for improving the efficiency of centrifugal compressors and reducing energy consumption.
