Morphing Airfoils with Four Morphing Parameters
An episodic unsupervised learning simulation using the Q-Learning method is developed to learn the optimal shape and shape change policy for a problem with four state variables. Optimality is addressed by reward functions based on airfoil properties such as lift coefficient, drag coefficient, and moment coefficient about the leading edge representing optimal shapes for specified flight conditio...
متن کاملusing adaptive meshing for solving the transonic flow around airfoils
numerical analyses have shown that successful flow simulations and the accuracy of solution noticeably depend on the number of nodes used in computational meshing. a suitable meshing should have the capability of adapting with main flow parameters. because the number of total nodes that can be used in numerical simulation is limited, making such grid for complex flows is almost difficult, if it...
متن کاملReinforcement Learning of Morphing Airfoils with Aerodynamic and Structural Effects
This paper applies a Reinforcement Learning methodology to the problem of airfoil morphing. The reinforcement learning as it is applied to morphing is integrated with a computational model of an airfoil. The computational model utilizes a doublet panel method whose end yield is airfoil lift, drag, and moment coefficients. An episodic unsupervised learning simulation using the Q-Learning method ...
متن کاملDynamic Meshing Using Adaptively Sampled Distance Fields
Many models used in real-time graphics applications are generated automatically using techniques such as laser-range scanning. The resultant meshes typically contain one or more orders of magnitude more polygons than can be displayed by today’s graphics hardware. Numerous methods have been proposed for automatically creating level-of-detail (LOD) meshes from large input meshes. These techniques...
متن کاملDynamic Meshing Characteristics of Elliptic Cylinder Gear Based on Tooth Contact Analysis
As the most important working area of gear, teeth play the role of transmitting load and power. Tooth line and tooth profile are the two main characteristics of the tooth surface, which affect the shape of the tooth surface, tooth meshing characteristics and contact characteristics. Taking the elliptical cylinder gear pair in the reversing device of a new type of drum pumping unit as the resear...
