International Journal for Numerical Methods in Fluids, Volume 95, Issue 7, Page 1054-1075, July 2023., 2023 A novel turbomachinery oriented volumetric parameterization technique is presented. It employs volumetric NURBS along with a coordinate system transformation, retaining axisymmetry and periodicity. Its combination with a GPU‐accelerated flow and adjoint solver is utilized for the shape optimization of a high‐pressure, transonic, turbine stage rotor ...

The Aerodynamic Characteristics of a Diamond Joined‐Wing Morphing Aircraft
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 This paper presents a new‐concept aircraft with a diamond joined‐wing morphing configuration, which simultaneously adjusts the sweep angles of both the front wing and rear wings by a telescopic support rod. The compressible Navier‐Stokes equations in the conservative form are solved to analyze the configuration characteristics and the aerodynamic ...

Design Improvement of a BWB Aerodynamic Performance at Cruise and Take‐Off Speeds
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 As a high‐performance aircraft, BWB (blended wing body) has attracted the attention of many countries around the world. A 300‐seat BWB design is proposed by the Airplane Concept Design Institute of Northwestern Polytechnical University, which is also called SWB. The aerodynamic performance of it is evaluated by CFD (computational fluid dynamics).

Robust fault tolerant control allocation for a modern over‐actuated commercial aircraft
IET Control Theory &Applications, Volume 15, Issue 2, Page 307-322, 29 January 2021., 2021 Abstract This paper presents a novel form of control allocation, designed within a sliding mode framework, for the fault tolerant control of over‐actuated systems. The control allocation is designed in such a way as to allow a subset of the actuators to remain inactive under nominal fault‐free conditions.
