Gust load alleviation by normal microjet
Aerospace Science and Technology, 2021 This paper presents an investigation on the capability of gust load alleviation by normal microjet. The numerical method integrates the unsteady Reynolds averaged Navier-Stokes (URANS) solutions, structural dynamic equations of motion and the Field Velocity Method. The method is verified for gust responses of rigid and elastic models.

Airfoil gust load alleviation by circulation control [PDF]
Aerospace Science and Technology, 2020 This paper presents a numerical investigation on the gust load alleviation effects based on circulation control (CC) via blowing over airfoil trailing-edge Coanda surface. The NACA0012 airfoil was chosen for the study from subsonic to transonic speeds. The field velocity method is introduced to the unsteady Reynolds averaged Navier-Stokes solutions to ...

Structural optimization for gust load alleviation
7th AIAA/USAF/NASA/ISSMO Symposium on Multidisciplinary Analysis and Optimization, 1998The subject of this paper is gust load alleviation through structural optimization methods. It explains some of the ways that gust loads can threaten the safety of a flight, and also describes the accepted way of characterizing gusts. In particular, the random nature of a gust and the associated simplifying assumptions in order to make the problem ...

Prediction of gust loadings and alleviation at transonic speeds
27th Structures, Structural Dynamics and Materials Conference, 1986Abstract : The transonic indicial theory is used to predict the effect of a gust on an airfoil at transonic speeds. The effect of operating two control surfaces is also modeled by the indicial method. The transonic indicial mehtod is linear in a strained coordinate system and superposition can be used.

Aircraft Design with Maneuver and Gust Load Alleviation
29th AIAA Applied Aerodynamics Conference, 2011of maneuver (MLA) and gust load alleviation (GLA) systems on aircraft performance are evaluated at the conceptual design level. Results suggest that a conventional transonic transport aircraft designed with an aggressive aerodynamic MLA system may achieve some 3% lower direct operating cost (DOC) and more than 4% reduction in fuel consumption relative ...
