“Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.”
― Leonardo da Vinci
Over the past few years, unmanned aircraft have become central to the functions of various businesses and governmental organizations and have managed to pierce through areas where certain industries were either stagnant or lagging. The Society For Industrial Management and Engineering (SIME), along with the Department of Production and Industrial Engineering, BIT Mesra, organized a four-week live session on the ‘Drone Design and Development Workshop’, which commenced at 11:00 A.M. on 3rd October, 2021. The event was conducted on the online video conference platform Google Meet. The esteemed guest speaker, Veteran Air Commodore Pradeep Kumar Choudhary, inspired and nurtured young minds on Drone technology and its technical details in a lucid and foolproof way. The workshop was followed by the drone design and concept development competition. Air Commodore PK Choudhary is the founder of General Aeronautics Private Limited, which is actively involved in the design and development of UAVs. He was commissioned in the Indian Air force in February, 1985 as an aeronautical engineer. In 31 years of its distinguished services, he has held several important appointments, including senior engineer of a premier fighter base, commanding officer of 4 BRD, and many more. A recipient of the Vishisht Seva Medal by the President of India for his distinguished service of a high order, he has been commended by Air Officer Commanding-in-Chief and Chief of Air Staff for his professionalism and achievements. Currently, he is a specialist consultant of mechanical systems and maintainability in the Aeronautical Development Agency (ADA). Over 30 students attended the session to gain knowledge of UAV technology and its workings. Mr. Choudhary started the session by providing a glimpse of the history of Drones, how they evolved with time, and their various structures according to the desired work.
He shared the knowledge of the VITOL Ariel Vehicle and threw light on its functioning and characteristics. Further, he introduced the students to the technical terminologies and elucidated the Quadrotor theory, the concept of Multiple Reference frames, Six Degree of Freedom (6 DOF), and the calculations related to it. Then, he gave a detailed and clear understanding of drone dynamics, covering the mathematical parts of its motion, and sign convention for navigation. Following this, he shared the slides and videos of these technical things for better visualization and understanding. Finally, he discussed Quadrotor dynamics, propeller thrust, moments, take off, and hover in detail.
In the end, Mr. Choudhary took up some questions from the students and cleared their doubts. The first day of a four-week workshop ended at 1:00 P.M., with Dr. Joyjeet Ghose, head of the Production engineering department, culminating the session with a vote of thanks to the guest speaker and fellow professors, who got together to make this event a successful one.
