In this paper,a series of flutter simulations are carried out to investigate the effects of split drag rudder(SDR)on the transonic flutter characteristic of rigid NACA 64A010.A structural dynamic model addressing two-...
The issue of nonlinear structural freeplays in aircraft has always been a significant con-cern.This study investigates the aeroelastic characteristics of a twin-tail boom Unmanned Aerial Vehicle(UAV)with simultaneous ...
Welcome to year 6 and volume six of the Journal of Integrative Nursing.It is an honor to join Professor Tang as Editor-in-Chief in cultivating an international community of scholars whose foci includes the topics list...

In this study,we designed a new,semi-balanced,twisted rudder to reduce the surface cavitation problem of medium-high-speed surface warships.Based on the detached eddy simulation(DES)with the Spalart-Allmaras(SA)model(...
This paper presents recent developments towards efficient and reliable methods for roll damping estimation based on numerical simulations as well as model tests using the harmonic excited roll motion(HERM)technique.A ...

Target strength(TS)and circular synthetic aperture sonar(CSAS)images provide essential information for active acoustic detection and recognition of non-cooperative unmanned undersea vehicles(UUVs),which pose a signifi...
Based on the incompressible RANS equation,the KVLCC1 ship’s resistance field’s numerical simulation is carried out.In this paper,the bare hull(calm water resistance and wave resistance)and hull-propellerrudder model...

Reducing the fuel consumption of ships presents both economic and environmental gains. Although in the past decades,extensive studies were carried out on the flow around ship hull, it is still difficult to calculate t...
A ship manoeuvring problem is solved using an algorithm built on fuzzy logic.The manoeuvring model for a design ship is coded in C++and the results are presented here.A bulk carrier is assumed as design ship for a new...
