From Clean Sky towards Clean Sky 2
Step changes in the “efficiency” of all airframe elements by the means of a systematic “re-thinking”
Re-think the a/c architecture
Re-think the fuselage
Re-think the wing
Re-think the control
Re-think the cabin
Smart Fixed Wing Aircraft
• Greener Airframe Technologies • More Electrical a/c architectures

Title: Development and validation of a portable, automated
and jigless system for drilling and assembly of fuselage joints
WP Location: AIR ITD WP B-4.3
Objective:
Development and validation of a flexible system for automated drill integrated holes inspection to be used for a regional aircraft composite fuselage assembly. Use of the system will allow a significant reduction of the overall production costs and flow.
The system will consist in a compact equipment, movable on curved surfaces, and able, through a dedicated Part Program, to perform one-shot drilling and hole inspection for assembly of primary structures. This solution will address longitudinal/circumferential joint of fuselage sections.

Tasks description:
• Task 1 - Trade-off Study and Tool Technical Specification
The advanced technologies development for an automated drilling system on the Regional
TurboProp fuselage shall be driven by the following key factors: increase of integration,
reduction of assembly flow, reduction of assembling costs and increase of automation..
• Task 2 Equipment design Equipment shall be designed as an integrated system of the three main components: drilling
and measuring head, head moving equipment (both X and Y axis, moving on the fuselage, at
specific locations for panels joint) and positioning and alignment system.
• Task 3 - Test Plan of the three main components and their integration After design, a Test Plan for each of the three main components shall be produced by the
Applicant, listing and describing all the tests that have to be conducted to develop the process.

• Task 4 - Equipment development and construction Equipment shall satisfy all design requirements. Tests required by plans shall be conducted during the equipment construction, thus supporting and orienting the development of the automatic equipment.
• Task 5 Pre-acceptance tests A pre-acceptance phase shall be conducted before equipment shipping to the Topic Manager plant in order to verify technology readiness and conformance to the requested performance level.
• Task 6 - Equipment Acceptance An acceptance task, similar but more in depth than pre-acceptance, shall be performed after final installation in the Topic Manager facility. A full-size demonstrator shall be successfully drilled, checked and assembled in order to validate the Equipment capabilities (6 longitudinal joints, 1 orbital joint).

Title: Development and validation of a self-adaptive system for
automated assembly of major composite aerostructures
WP Location: AIR ITD WP B-4.3
Objective:

Capability:
This solution will be applied for the assembly of stiffened panel skins, frames, window frames and door surround components.
Recognition of actual position and shape of sub structure is performed by a dedicated camera system, so that a specific algorithm will elaborate the 3D model holes pattern on the basis of the actual structure position and profile. Camera system and algorithm shall be able to perform visual and dimensional checks by matching the actual data with requirements and providing report.
Reference components is shown in figure 1.
