The basic functions of the helicopter are understood in connection with the rotor blade mechanism principle, aerodynamic theory, and flight principle such as hovering. Students will also learn about basic equipment and power system overview, operational issues including noise and flight safety, and mechanisms of abnormal events that occur during operation such as settling with power and loss of tail rotor function.
In this course, you will gain the knowledge necessary to understand the on-site issues related to DP1.
The goal of this lecture is to understand the flight characteristics of a helicopter with a unique shape and system, and to know the various devices that make up the helicopter, based on basic knowledge such as aerodynamics related to aircraft.
(1) Explain basic principles of aerodynamic theory, flight principles, stability, and maneuverability of helicopters
(2) Explain outline of mechanical device for flying
(3) Understand and explain the characteristics of the structure, landing gear, etc. that have a different aspect from the fixed wing aircraft
The result is evaluated based on the regular examination. (100%)
Test results will be returned to each student and the necessary feedback will be given.
