Magnus Effect over Aerodynamic Components of Spinning Missile

Gao, Yi; Lei, Juanmian; Yin, Jintao

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00452-9

To reveal the flow mechanism of the Magnus effect of the spinning missile, the flow field under supersonic conditions was numerically simulated based on the unsteady Reynolds-time-averaged Navier–Stokes equation, and the implicit dual-time stepping method and sliding mesh method were used....

The Investigation of Rotating Instability Under Distortion Based on a Compressor Rotor

Zhang, K.; Park, W. G.

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00467-2

The twisted-swept fan is one of the most important components of a high bypass ratio engine. Under clean inlet flow or inlet distortion, the unsteady flow field of the fan rotor near stall condition is obtained by numerical simulation. At the same time, fast Fourier transform (FFT) transformation...

Research on a Robust Overset Grid Method for Load Calculation of Coaxial Rotor

Yucheng, Yang; Guohua, Xu; Yongjie, Shi

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00460-9

In this paper, a robust overset grid assembly technology suitable for the coaxial rotor in flow field calculation is established and two kinds of interpolation boundaries including so-called Max-hole boundary and Max-overlap boundary are proposed. The technology is applied to the computational...

An Angular Discretization Method Using Repulsive Particles for the Three-Dimensional Radiative Transfer Equation

Jung, Seongmun; Jo, Sung Min; Kwon, Oh Joon

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00468-1

In the present study, a new angular discretization method, repulsive particle angular discretization (RPAD), is proposed for use with the three-dimensional radiative transfer equation (RTE). To discretize a solid angle as uniformly as possible, mutually repulsive particles on the unit sphere were...

The Study of Mach Waves Generated by a Roughness Element

Dinh, Hoang Quan; Nguyen, Anh Tuan; Egorov, Ivan Vladimirovich; Duong, Ngoc Hai

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00471-6

In this paper, a simplified inviscid boundary condition is applied to solve the problem of Mach waves generated by a roughness element on the wall surface of a supersonic wind tunnel. The geometry of the roughness element is simplified by a parabolic function, to which mathematical formulas are...

Estimation of Effective Mechanical Properties of Plain Woven Composites Using Direction-Selective Micromechanical Models

Kim, Dong-Hyeop; Kim, Sang-Woo

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00459-2

The directional elastic properties of composite yarn calculated by micromechanical models depend on the type of the models directionally adopted, and which significantly impacts the estimation of effective mechanical properties of woven composites composed of yarns and matrix (resin). This study...

Performance Design of a Turbofan Engine Using Multi-objective Particle Swarm Optimization (MOPSO)

Lee, Dong-Sun; Sung, Hong-Gye

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00451-w

The performance design of a turbofan engine is carried out to find a set of Pareto optimal solutions satisfying multiple conflicting and/or competing objectives simultaneously within objective constraints by applying multi-objective particle swarm optimization. A gas path analysis is incorporated...

Coking Test Using Jet A-1 and Desulfurized Kerosene in a Regenerative Cooling Channel Environment

Lee, Dain; Lee, Kangyeong; Han, Sunwoo; Ahn, Kyubok

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00463-6

The walls of a liquid propellant rocket engine generally employ regenerative cooling channels to reduce the enormous heat load generated by the combustion of the fuel and oxidizer. When a hydrocarbon fuel is heated to a high temperature in such an engine, the reaction between the copper in the...

Collision-Free Adaptive Control for UAV Formation with Input Saturation and Communication Delays

Lu, Jianhui; Luo, Fan; Zheng, Zhong; Hou, Mingxin; Wang, Lin

2022 International Journal of Aeronautical and Space Sciences

doi:10.1007/s42405-022-00447-6

This paper addresses the collision-free adaptive formation control problem for multiple unmanned aerial vehicles subject to input saturation and communication delays. First, a novel collision-free adaptive saturated control scheme is proposed using potential function and anti-windup compensator...
