Major Structural Modifications on a Boeing 777-200LR Fuselage

01/13/2021

The exponential evolution in the aeronautic industry in the last century opened the market for new business opportunities such as aircraft modifications. Whether it is a repair or an alteration, these modifications must be certified, by the company that is doing them or, in case they do not have the privileges to do so, by a regulatory agency such as the European Union Aviation Safety Agency (EASA) or the Federal Aviation Administration (FAA), through the use of a Supplemental Type Certificate (STC). In this thesis, two major modifications are presented : i) a Ka-band antenna, used for wireless internet access and ii) a quad camera used for passenger entertainment. For both cases, a careful and detailed aircraft environment definition, at the installation area, is done, since it is considered to be one of the keys for design success. All structural provisions are produced by Jet Aviation, in-house, for both installations, although for the Ka-band antenna integration there is the additional guidance from the industry standard Aeronautical Radio Incorporated (ARINC) 791. Three quad camera design variations are studied by using the finite element method (FEM), in order to achieve a weight and cost reduction, while maintaining the structural integrity. Finally the important documents needed in order to apply for the STC are presented.
