| １． |
Outline |
|
In this course, students will design a helicopter of the scale that they chose themselves according to typical conceptual design methods that will be shown in the lectures. Students will understand numerically the aerodynamics of the rotor and the flight dynamics of the helicopter through the design.
|
| ２． |
Objectives |
|
The goal of this course is to understand the flight mechanism and aerodynamics of the helicopter through the conceptual design of the original helicopter according to basic process. In addition, the lectures address problems that should be settled by the helicopter design and aim to understand flight properties and performances.
|
| ３． |
Grading Policy |
|
Results will be evaluated by reports with own design procedure and discussion in the lecture.
|
| ４． |
Textbook and Reference |
|
Texts and some materials will be distributed.
|
| ５． |
Requirements (Assignments) |
|
It is desirable for students to have studied "Introduction to Helicopter Engineering" in the undergraduate course. Furthermore, “Fundamental Design Technology of an Airplane” and “Airplane Dynamics” will also be needed. In the lectures, the supplemental explanation shall be given with the presentation materials depending on the understanding level of participants. However, a preparation learning with using the reference books introduced in the class is recommended.
|
| ６． |
Note |
|
Students will design a helicopter based on what they learn in lectures. They will give presentations about the design progress status when appropriate and discuss their results.
