Wing-Rotor Aerodynamic Interactions in Small UAVs During Hover and Cruise
Dev Pradeepkumar Nayak, Seungmin Choi, Muhammad Saif Ullah Khalid
A compact vertical take-off and landing aircraft requires the same tilt-rotor configuration to perform two fundamentally different aerodynamic tasks: sustain hover and deliver effi…

Dynamical Characteristics of the Body-Caudal Fin Joint of a Carangiform Swimmer and its Influence on Hydrodynamics
Dev Pradeepkumar Nayak, Muhammad Saif Ullah Khalid, Ali Tarokh
The hydrodynamics of fish swimming depend on the interaction between the undulation of the body and the flapping of the caudal fin. This study develops a computational framework of…

Comparative Investigations on Active and Passive Tails of Undulating Swimmers
Dev Pradeepkumar Nayak, Ali Tarokh, Muhammad Saif Ullah Khalid
Fish display remarkable swimming capabilities through the coordinated interaction of the body and caudal fin, yet the potential role of a passively pitching tail in enhancing hydro…
