Efficient Multidisciplinary Analysis Approach for Conceptual Design of Aircraft with Large Shape Change [PDF]

open access: yes, 2009
The conceptual and preliminary design processes for aircraft with large shape changes are generally difficult and time-consuming, and the processes are often customized for a specific shape change concept to streamline the vehicle design effort ...

Discrete adjoint-based simultaneous analysis and design approach for conceptual aerodynamic optimization [PDF]

open access: yes, 2017
In this paper, a simultaneous analysis and design method is derived and applied for a non-linear constrained aerodynamic optimization problem. The method is based on the approach of defining a Lagrange functional based on the objective function and the ...

On the effect of low blowing ratio continuous jets on wingtip vortex characteristics [PDF]

open access: yes, 2018
Vortices are an unavoidable effect of flight, which appear behind the wing with a bounded length. The strength of these vortices, which are extremely stable, is due to the lift force [1].

SurfNet: Generating 3D shape surfaces using deep residual networks

open access: yes, 2017
3D shape models are naturally parameterized using vertices and faces, \ie, composed of polygons forming a surface. However, current 3D learning paradigms for predictive and generative tasks using convolutional neural networks focus on a voxelized ...

Perspectives on Highly Adaptive or Morphing Aircraft [PDF]

open access: yes, 2009
The ability to adapt to different flight conditions has been fundamental to aircraft design since the Wright Brothers first flight. Over a hundred years later, unconventional aircraft adaptability, often called aircraft morphing has become a topic of ...
