Elevated Skid Design for an Unmanned Disaster Relief Helicopter
AbstractDevelopment of unmanned disaster relief helicopters is need of developing countries like Pakistan to save the lives of disaster victims. As a part of research on the development of unmanned disaster relief helicopter at National University of Sciences and Technology (NUST), this paper aims to address the problems of installing disaster relief equipment on a Radio Controlled (RC) model helicopter. Skid elevation is essential in order to facilitate the installation of disaster surveying equipment like video and data telemetry system. This paper proposes an elevated skid design as a potential solution to the problem. The Structure of elevated skid has been simulated for the static structural analysis to check its safety and reliability. Simulation results and overall design of proposed elevated skid has been compared with the existing skids. Virtual Computer Aided Design (CAD) PRO-E has been used for the modeling of elevated skid and ANSYS has been used for the simulations of proposed design. Proposed elevated skid has been specifically designed for the 90 size model helicopters and can be utilized to attach the additional imagery and data telemetry equipment beneath the helicopter.
