Mysore :
The Eighth Semester Mechanical Engineering students of Maharaja Institute of Technology (MIT), Mysore, have excelled in their project with the ‘Design and Frabication of Unmanned Aerial Vehicle (UAV) – Y4 Copter’ recently.
The project was carried out by Mohan Keerthi, S.T. Savanth, K. Ashwini and P.B. Pramod under the guidance of Dr. Mohamed Khaisar, Professor and HoD, Department of Mechanical Engineering and Dr. Y.T. Krishnegowda, Professor, Dept. of Mechanical Engineering and Secretary,Maharaja Education Trust (MET), Mysore.
An Unmanned Aerial Vehicle (UAV), commonly known as a drone and referred to as a Remotely Piloted Aircraft (RPA) by the International Civil Aviation Organization (ICAO), is an aircraft without a human pilot aboard. Its flight is controlled either autonomously by onboard computers or by the remote control of a pilot on the ground or in another vehicle.
They are usually deployed for military and special operation applications, but also used in a small but growing number of civil applications, such as policing and fire-fighting, and non-military security work, such as surveillance of pipelines. UAVs are often preferred for missions that are too ‘dull, dirty or dangerous’ for manned aircraft.
As a tool for search and rescue, UAVs can help find humans lost in the wilderness, trapped in collapsed buildings, or adrift at sea.
The name Y4 Copter is named after the shape of the aircraft resembling the alphabet ‘Y’ and ‘4’ is due to number of propellers used are four. The complete design and all the stages of fabrication process and assembly were solely carried out by the students at the college premises.
Automation is implemented to maintain the desired roll, pitch and yaw. There are two propellers and motors at the front on two separate arms and two co-axial propellers and motors at the rear end. The relative motions of roll and pitch are achieved by tilting mechanism by servos. There are two servos, one for the roll movement and the other for the pitch movement. The total system is powered by the battery.
The flight and movement of the Y4 Copter is controlled by the wireless system called radio controller. A custom remote is built to communicate with the Y4 Copter which offers long range and security. Dr. B.G. Naresh Kumar, Principal-Maharaja Institute of Technology witnessed the testing and first flight of the Y4 Copter and appreciated it.
