Aeroelastic Scaling of a High-Aspect-Ratio Wing Incorporating a Semi-Aeroelastic Hinge AIAA J. (IF 2.5) Pub Date : 2024-04-17 Huaiyuan Gu, Fintan Healy, Lucian Constantin, Djamel Rezgui, Mark Lowenberg, Jonathan E. Cooper, Thomas Wilson, Andrea Castrichini
There has been a growing interest in utilizing flared folding wingtips as an in-flight load alleviation device to enable increased wing spans that meet airport gate limits but with little increase in wing weight. The semi-aeroelastic hinge (SAH) concept is implemented in high-aspect-ratio wings to enable wingtips to be released during severe load cases such as maneuvers and gusts to alleviate the bending

State Observing Method and Active Vibration Control Based on Virtual Sensing AIAA J. (IF 2.5) Pub Date : 2024-04-05 Yuhan Sun, Zhiguang Song
State feedback is mostly used in the active vibration control of structural systems. However, the most challenging problem is to achieve the whole state of the structure. Another issue in active vibration control is that, in many cases, only some particular modes need to be controlled, while the other modes can remain unchanged in order to save on the costs of the control. To solve the above issues

The investigation of flow separation control over a NACA 0015 airfoil model using a fluidic oscillator (FO) is conducted through delayed detached eddy simulation. First, the flowfield within and outside an FO operating in quiescent air is resolved simultaneously. The oscillation of the jet flow induced by the FO is attributed to the cyclic expansion and contraction of the recirculation bubbles located

Buzz Characteristics Under Fluid–Structure Interaction of Variable-Geometry Lip for Hypersonic Inlet AIAA J. (IF 2.5) Pub Date : 2024-03-31 Kun Ye, Xinxin Zhou, Zhengyin Ye
Variable-geometry lip structures can effectively broaden the operating range and improve the performance of hypersonic inlets. However, the presence of connection devices leads to a significant reduction in structural stiffness, which can easily trigger fluid–structure interaction (FSI) issues of the lip. In this study, an in-house FSI program is employed to investigate the buzz characteristics under

Machine-Learning-Enhanced Real-Time Aerodynamic Forces Prediction Based on Sparse Pressure Sensor Inputs AIAA J. (IF 2.5) Pub Date : 2024-03-31 Junming Duan, Qian Wang, Jan S. Hesthaven
Accurate real-time prediction of aerodynamic forces is crucial for the navigation of unmanned aerial vehicles (UAVs). This paper presents a data-driven aerodynamic force prediction model based on a small number of pressure sensors located on the surface of a UAV. The model is built on a linear term that can make a reasonably accurate prediction and a nonlinear correction for accuracy improvement. The

Enhanced Aerodynamic Performance of a Two-Dimensional Airfoil Using Moving Boundaries AIAA J. (IF 2.5) Pub Date : 2024-03-30 Rushikesh Fale, Manikandan Mathur, Bharath Govindarajan
The effects of moving boundary conditions on the aerodynamic performance of a two-dimensional NACA 0012 airfoil at different angles of attack (α) in a uniform freestream at a Reynolds number of 10,000 are numerically studied. The moving boundary conditions are motivated by inviscid potential flow around the airfoil, which also satisfies the viscous equations of motion. In this study, the wall is moved

This paper concerns the interaction of an impinging shock wave with a supersonic turbulent boundary layer over several distinct and permanently deformed surfaces, resulting in differences in the shock–boundary-layer interaction and the surface acoustic loading. High-order numerical simulations featuring two-dimensional surface deformations typically encountered in experiments are performed. The deformation

Aerodynamic Performance of a Finite-Span Wing in a Time-Varying Freestream AIAA J. (IF 2.5) Pub Date : 2024-03-23 Dasha Gloutak, Kenneth E. Jansen, John A. Farnsworth
The current study analyzes the dynamic response of a NACA 0015 finite-span wing to a time-varying freestream in an unsteady wind tunnel at a mean Reynolds number of 1.0×105. The aerodynamic response of the wing can be categorized based on the angle of attack and the degree of flow separation on the suction side of the wing. When the suction side is dominated by separated flow, either at low angles

The presence of grazing flow can alter the noise reduction performance of resonant liner panels. One possible cause is the flow entering the liner opening. In this study, a fine perforated film was applied to the surface of acoustic liners to prevent such flow effects. Three types of liner samples were fabricated and tested in a flow duct rig at the Japan Aerospace Exploration Agency. The first sample
