Special Lectures on Helicopter Engineering |
HIRAMOTO, Takashi |
|
|
【Doctor's program･full year】
19-3-1043-3035 |
| １． |
Outline |
|
In this course, students will discuss the problems of an actual helicopter, analyze its mechanism, and take counter measures.
|
| ２． |
Objectives |
|
The helicopter is more unstable than an airplane. Therefore even a slight disturbance can have a large impact due to resonance phenomenon.
In this course, the understanding of the flight principle of the helicopter will deepen by considering for the means to improve safety and the factors and mechanisms bringing a helicopter to a critical situation.
|
| ３． |
Grading Policy |
|
The results are evaluated by discussions and reports.
|
| ４． |
Textbook and Reference |
|
Text materials will be distributed in lectures.
Reference books will be shown as required.
|
| ５． |
Requirements (Assignments) |
|
This course is more specialized than the undergraduate class and the master's course. For the students, it is necessary to understand the mechanism and the flight principle of the helicopter.
A phenomenon and its conditions are shown before the class. Based on them, consider for the motion and behavior of helicopter.
|
| ６． |
Note |
|
In this course, students will be shown emergency situations and other phenomena, and these will be analyzed and discussed.
|
| ７． |

| 10. Motion affected by wind shear and turbulence in flight |
| 11. Motion affected by wind shear and turbulence in flight |
| 12. Motion affected by wind shear and turbulence in flight |
| 13. Mechanism and countermeasures of ground resonance |
| 14. Mechanism and countermeasures of ground resonance |
| 15. Mechanism and countermeasures of ground resonance |
