An automated system shall be developed to operate in a very flexible way, for panel longitudinal joints and barrel circumferential joints. Thanks to a jigless and portable architecture, the system shall follow the actual outer surface, moving on it with a suitable indexing and holding device. The system shall demonstrate the capability to drill in an accurate way and to insert sealant and fasteners, this in order to achieve the one-up process with significant flow reduction. After machine development and validation, the system will be used at TM facilities on a regional a/c fuselage full scale demonstrator. Please refer to the full and formal topic descriptions published in this call.
