Performance Simulation Of The Land And Air Vehicle With Gyroplane Rotor

The land and air vehicle with gyroplane rotor is a multi-domain mobile platform which can drive and fly, the vehicle can realize ricochet and unpowered landing safely. The land and air vehicles in counter-terrorism, patrol, rescue, transportation and other aspects can play an important role. The four parts of work are the overall parameter design of the land and air vehicles, the vehicle dynamics model, performance simulation and analysis of the vehicle and visual simulation.In the overall design part, first of all, combined with given indicators and the demand, comparing with various flight plan, choose the initial flight plan and calculate the parameters of the main components. Introduce the principle of the gyroplane and parameters of the main rotor, propeller, vertical tail are calculated, finally completed the parameter calculation of drive components.For researching the flight dynamics, build the flight dynamic model. First of all, all parts of the model are builded under different coordinate respectively, and then take the forces and moments which are produced by all the parts into the body coordinate system to be composited, which constitute a mathematical model of flight. Dynamics model is the basis of simulation, balancing and stability analysis.According to the established dynamic model, simulate the performance of the vehicle. Balancing analysis was carried out on the model, research the changes of the manipulated variable under the different stable forward speeds. The lift and drag characteristics of each parts are studied. The characteristics of the main rotor are researched as well. Combine with the ricochet theory, simulate altitude and speed changes in the process of flying. Design a ricochet test, and then make a contrast with the test results and the theoretical calculation which can proof the accuracy of the simulation.Using the Vehicle simulator which is a flight simulation software for visual simulation. Combined use CATIA and 3ds max to build a three-dimensional model. Control instructions are given. Finally, demonstrate in the scene.
