Development of an Active Aeroelastic Parametric Wing Apparatus

This paper presents the development and initial characterization of an active, para- metric wing section with aileron and spoiler control surfaces. This wing section is intended to replace the currently used passive wing section setup and facilitate research in active con- trol techniques of aeroelastic phenomena such as flutter, gust load...

Aerodynamic and Performance Analysis of Ground Spoilers on the Flying V

Optimal design of a lift dumping assembly (LDA) has been found utilizing a gapped spoiler design that consists of two separate surfaces that are placed at 0.06b-0.17b and 0.28b-0.038b spanwise locations. The gapped design allows the cross flow amplified at the hingeline of the inboard spoiler to escape through the middle gap increasing the lift...

Bleed Air Spoiler Optimisation for AWE Purposes: An aerodynamic optimisation of upper surface bleed air control to minimise reel-in power loss for soft-kite-based Airborne Wind Energy systems

A key challenge in the Airborne Wind Energy industry is the minimisation of the time and energy required for the transfer and return phases inherent to the power cycles of ground-generator-based kite power systems. This thesis contributes to solving this problem by exploring the use of bleed air spoilers during the return phase in terms of their...

Unsteady Non-linear Control Surface Modelling for Aeroservoelastic Applications

In this paper, we present a data-driven method to model the unsteady non-linear response of aircraft control surfaces. This method relies on aerodynamic reduced-order models (ROM) derived from computational fluid dynamics with Reynolds averaged Navier-Stokes (CFD-RANS) analysis in the transonic domain. The ROM consists of a combination of look...

Hydrodynamic forces on a near-bed offshore pipeline with spoiler, during the selfburying process

To prevent offshore submarine pipelines from damage by fishing gear, the formation of dangerous free-spans and excessive wave and current forces, it is a requirement that these pipelines are completely buried under the seabed. Usually pipelines are buried artificially by means of ploughing, digging or jetting in order to meet the requirements of...
