Helicopter Law Of Motion And Flight Simulation

As the part of the project of "XXXX", this thesis is about the motion trends of helicopter, which is also simulated. And the main results are listed as follows:(1) Analyze helicopter's dynamic model and motion trends, as well as the typical force condition.When the rotors and fuselage of helicopter are looked as the whole part, general flight dynamics model is constructed and 6-dof state equation about rigid motion is given according to Newton Law. As for the complex problems such as rotors' dynamic characters, the typical force condition is analyzed by assuming some conditions. As a result, helicopter's force and torque are calculated.(2) Construct three- dimensional model of the helicopter and background with the help of 3D Studio MAX.(3) Design the software of the flight simulation of helicopter.I designed the software to control the flight of helicopter in C++ language by using OpenGL, a kind of 3D scene driving software. After receiving commands from the keyboard or local network, the software can show the flight mode of helicopter. It is demonstrated that visual simulation software can work well, reaching the goal of simulating the motion trends of helicopter.
