The effects of aeroelastic deformation on the unaugmented stopped-rotor dynamics of an X-Wing aircraft [PDF]
A new design concept in the development of VTOL aircraft with high forward flight speed capability is that of the X-Wing, a stiff, bearingless helicopter rotor system which can be stopped in flight and the blades used as two forward-swept and two aft ...

FLEXOP - Application of aeroelastic tailoring to a flying demonstrator wing [PDF]
, 2018 This paper presents the application of aeroelastic tailoring in the design of flying demonstrator wings. The work is part of the Flutter Free Flight Envelope eXpansion (FLEXOP) project, funded under the Horizon 2020 framework. The project involves the design, manufacturing and flight-testing of a UAV toward two principle goals: i) to demonstrate the ...

Aeroelastic tailoring of a sailplane wing
, 2011 In this paper a process for how to perform aeroelastic tailoring of a sailplane wing is described. The analysis was carried out with the aid of a Finite Element solver and the aerodynamic loads were calculated with a potential flow solver. The design parameters of the process were mainly the number of carbon fiber plies and their orientation, but it ...

Aeroelastic Tailoring Of Woven Cantilevered Glass-Epoxy Plate-Like Aircraft Wing [PDF]
, 2008 The application of uni-directional composites in aeroelastic tailoring has long been established due to their highly directional properties. However, the use of woven, bi-directional textile composite in this area is practically nil due to their lower ...

Aeroelastic Tailoring of an NLF Forward Swept Wing [PDF]
, 2016 This article introduces the application of a multidisciplinary analysis (MDA) process chain based on high fidelity simulation methods for the aeroelastic tailoring of an natural laminar flow (NLF) forward swept wing. With this approach the interactions between aerodynamics, loads and structural sizing are considered in the wing analysis.

A review of research in rotor loads [PDF]
The research accomplished in the area of rotor loads over the last 13 to 14 years is reviewed. The start of the period examined is defined by the 1973 AGARD Milan conference and the 1974 hypothetical rotor comparison.
