Life extension of UAVs: a case study of Indian UAVs

Abstract

Unmanned Aerial Vehicles (UAVs) are an integral part of any Armed force. They are being used in dull, dirty, dangerous and demanding missions. These missions restrict the life of UAV thus increasing the cost of UAV operations. To keep the operational cost low, it is essential to utilize UAVs to their full potential and life. The process of aging of UAV which results in structural and performance deterioration cannot be stopped, but its impact can be limited by using preventive measures, proper maintenance and implementing the required changes. A well-used UAV can be a befitting candidate for Life extension. Life extension of UAVs cannot be just on economic factors but also on reliability and performance in the extended life. This paper presents the case study of life extension of Indian UAVs which are designed and developed by Aeronautical Development Establishment, Bengaluru. These UAVs have been field tested and operationalized by Armed forces under varying environmental and usage conditions. The procedure, conditions and lessons learnt during the life extension process of UAVs are described. Life extension of these UAVs has resulted in considerable amount of cost and time saving to the users.
