Velocity vector - incidence angle of aero profil - MotionView
Hi, I'm working on an aero project on MotionView. I need to return the incidence angle for a lift force calculation. The incidence angle is the angle between the Chord line of my aerodynamics profil (represented by one of the direction of a marker in my model) and the vector of his relative velocity, Vr. To calculate Vr, I…

Landing Gear Simulation with Hydraulic Control in MotionSolve and Twin Activate
Overview INTRODUCTION Landing gear are employed on most aircraft for ground operations and landings. Engineers must design landing gears to handle the impact loads during aircraft touchdown and absorb the shock of the landing to prevent damage to the aircraft. There are three main types of struts used in the aircraft…
