Flutter prediction, suppression and control in aircraft composite wings as a design prerequisite: a survey [PDF]

open access: yes, 2007
Emergence of flutter compromises not only the long-term durability of the wing structure, but also the operational safety, flight performance and energy efficiency of the aircraft. Effectual means of flutter prevention are, therefore, mandatory in the

Aerodynamics of variable geometry wing/body combinations [PDF]

open access: yes
A description of the experimental investigation of the aerodynamic characteristics of variable geometry of an aircraft model is presented. Aerodynamically, the model is tested-for a sweep range of 0°,12.5° 32.5°, and 52.5° and incidence range of 0° to ...

Identification and attenuation of slat noise [PDF]

open access: yes, 2012
In the case of civil transport aircraft, engines were the dominant noise source until the advent of the high-bypass ratio engines in the early 1970s. Since then, airframe noise has become more important, particularly during the approach-to-landing stage ...

Application of panel methods for subsonic aerodynamics

open access: yes, 1985
Several panel methods are developed to model subsonic aerodynamics. The vorticity panel method for two-dimensional problems is capable of handling general unsteady, potential, lifting flows.

A Novel Airframe Design Methodology For Silent Aircraft [PDF]

open access: yes, 2008
The impact of noise on civil aviation is not just a localised airport problem, but a global concern, due to the ever-increasing demands for passenger travel.

Aerodynamics and aeroacoustics of wings and rotors via BEM - Unsteady, transonic, and viscous effects

open access: yes, 1998
Recent developments on a general boundary integral formulation for the aerodynamic and aeroacoustic analyses of lifting bodies (e.g., wings and rotors) are reviewed.
