Abstract :

A jet blast produces tremendous amount of thermal energy and noise. In order to prevent mishaps or equipment failure of machines nearby blast fences are used. A blast fence is often called as a “blast deflector” by the layman. A blast fence or a jet blast deflector (JBD) is a safety device which redirects the high energy from a jet engine to prevent accidents/damages. The structure is strong enough to deflect the high velocity debris carried by the turbulent air and heat. It is designed to provide a simple and aesthetically pleasing appearance. Blast deflector provides positive protection for ground vehicle, pedestrians and other airport facilities that may be subjected to jet-blast hazards from nearby runways .The structure includes two structural members, a curved rib channel member securely and hingedly attached to an airport apron and a vertical King Post of angle iron which is rigidly secured at its lower end and hingedly attached at its upper end to the channel. At airports blast fences are complementarily used with sound-deadening walls with which a jet/aircraft can be tested silently and safely. Without blast fence, the high intensity jet blast can be dangerous to people or other machines near the aircraft. In the present paper an attempt has been made to focus on design criteria, selection of structural members for analysis of jet blast deflector fence using E-TAB software. Keywords— E-TAB, Jet blast deflector (JBD), Structural members, curved rib channel member, vertical king post member.
