Avionics Rack Structure Strength Analysis during Emergency Landing on CN-XXX Aircraft

Abstract

The aviation industry is currently developing rapidly. The Avionics rack is one of the most important parts of an aircraft which functions to place various electronic devices to support the aircraft during flight. As explained in CASR 25 point 25.561, of course, the avionics rack itself is specially designed so that the rack structure can withstand various flight conditions, one of which is when the aircraft experiences an emergency landing. Emergency landings that are generally experienced by aircraft will experience a G-Force of 9G forward, 6G downward, 3G upward, 3G sideward, and 1.5G rearward. This research aims to measure how strong the structure and materials used are to support the devices stored on the avionics rack. Through the Finite Element Analysis method using software, hand calculations in calculating the Margin of Safety, as well as shear force analysis and bending moment diagrams, results can be obtained that the analysis carried out on the identified structure is declared safe if something crucial occurs such as an emergency landing.
