Wing Secondary Structure - Large Civil Jet Transport (MTOM > 40t) - Statistical Mass Estimation

Dies ist die aktuellste Version dieses Eintrags.

Kurzfassung

The scope of the presented paper is to present a set of formulae that can be used to compute the mass off all secondary structures of wings of large civil jet transport aircraft. Secondary structures are all wing structures that do not belong to the wing box (skin, ribs and spars). The developed formulae are for ‘large’ aircraft having a maximum take of mass (MTOM) of more than 40t respectively having 70 or more passenger seats in a typical layout. The mass computation is split into 18 main components of the wing secondary structures such as flap bodies, spoiler bodies, fixed leading edge etc. For each component one separate formula is developed in chapter 4. A brief description of the definition of each mass is given for each component. As the split into 18 components is very detailed one might also sum up the different masses according to different mass accounting standard, such as e.g. DIN9020 or the Airbus Mass Standard. Finally the validation of the different formulae is given in chapter 5.
