Crash Analysis of Unmanned Aerial Vehicle Using FEA

Abstract

Even though there are lots of technology advancements in the field of Unmanned Aerial Vehicle (UAV), there is a high possibility that an aerial vehicle will crash during initial test trials and in subsequent flights and hence loss high-cost equipment’s along with the loss of aeroplane structural components and money invested on it. The main interest in the present work is to analyse the possible accidents that designed UAV goes through and find out the peak impact forces at the important locations in the UAV where most of the electronic equipment’s are installed. In any crash, we cannot avoid damage to the structure. So even after the crash, we should not lose the data which is acquired during the surveillance, terrain mapping, reconnaissance, in this work our aim is to extract the peak impact (nodal dynamic forces) at Main electronic equipment like a surveillance camera, servomotors, fuel tank, payload, receiver etc. After crash no structure is safe but the costlier components like a surveillance camera, servomotors, fuel tank, payload, receiver etc. can be reused to rebuild UAV within less time and can be made ready for successive flight with no much difficulty in design and construction.
