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

, 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 ...

Fluid–Structure Interaction Analysis of the Fish Bone Active Camber Mechanism [PDF]

, 2015
A coupled, partitioned fluid/structure-interaction analysis is introduced for calculation of the deformed equilibrium shape, aerodynamic coefficients, and actuation requirements of the fish-bone-active-camber morphing concept. The fish-bone-active-camber

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

One Dimensional Morphing Structures for Advanced Aircraft [PDF]

, 2012
Since the Wright Brothers’ first flight, the idea of “morphing” an airplane’s characteristics through continuous, rather than discrete, movable aerodynamic surfaces has held the promise of more efficient flight control. While the Wrights used a technique known as wing warping, or twisting the wings to control the roll of the aircraft (Wright and Wright,

Climate Change Responses in the Pacific: Just Transformation or Transforming Justice?

Geo: Geography and Environment, Volume 13, Issue 1, January‐June 2026.
Short Abstract Through considering four types of ‘fatigue’, this article asks whether or not transformation and justice approaches for climate change account for on‐the‐ground circumstances of Pacific Islands and Islanders. The critique indicates how the identified difficulties could be overcome through the Pacific approach of talanoa. ABSTRACT Pacific

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

, 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 ...
