Investigation of Heaving-pitching Airfoil in Ground Proximity using Large Eddy Simulations [PDF]
Journal of Applied Fluid MechanicsThis study examines the aerodynamics of a wing-in-ground (WIG) airfoil subjected to heaving (plunging) & pitching motion, specifically examining the distinctions in flow between transitional and turbulent states, which are essential for assessing its ...

Forearm Trajectory Measurement during Pitching Motion using an Elbow-mounted Sensor
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2009 This paper describes a measurement method of three-dimensional (3D) forearm movement during pitching motion using an elbow-mounted sensor (3D sensor). The 3D sensor comprises accelerometers of two kinds with dynamic range of 4 [G] and 100 [G], and two ...
