| Summary: | 碩士 === 中華科技大學 === 飛機系統工程研究所 === 100 === Nowadays the present fast developing UAV (Unmanned Aerial Vehicle), the near mature systems offered by the related industries, along with the fast changing modern control, communication, and navigation technology, bring up the surge demand for UAV no matter for commercial or military purposes.
This study focus on the analysis and discussion on the design and implementation of the flying car. The typical UAV development is based on the traditional flying vehicle as ference, and shrink down the size to make sure the task requirement and then proceed to the design of each part of the platform/vehicle. The key technology for the design of the UAV is aerodynamic shape and stability controlling system designs. Among them, the first step of design lies in the static and dynamic stability of the airframe. Flying car using the car-shape as the vehicle frame can run as agile as a car while on the ground, and flies while up in the sky. Due to the fact that few studies on the flying car have been conducted in the past, plus lacking of relevant aerodynamic data, this study put various design into consideration to design the shape and do the testing. By utiliting the design theories of the model plane aerodynamics, we build the frame with lighten materials and perform tests and analyze the angle of attack, angle of the dynamic line, and position and the CG with the try and error approach. At the end, we describe the designing and building process of 3 types flying car in detail.
Besides, the kinematics equations of six degrees of freedom were used in this study to analyze the Longitudinal and Lateral dynamic movements of six different types of airplanes to form the basis for the flight control system design of the aircraft. Since the flying car is a car that can fly in a three dimensional space, its physical characteristics and flying dynamics are similar to those of airplanes. Based on analysis result of the airplane’s Longitudinal and Lateral dynamics movement, incorporating with a controller to meet the flying quality specification, we utilizes the Matlab\Simulink computer aid computer assist control system designing software to implement the simulation and verification analysis. This study will offer the technique for flying car design and implementation. After achieving the wind tunnel testing dynamics data of the flying car, the dynamic movement analysis result and the method of designing flight control system of this study can be used for the design and implementation of the flying car.
