To reduce time to design
aircraft electrical harness. |
|
To maintain and overhaul
electric cabling by a smart system. |
| |
|
Computer Aided
Design (CAD) systems have paved the way, in the
past twenty years, for cost reductions in aircraft
design; new cost reductions are foreseeable from
an extension of the CAD capabilities.
In the specific case of the electrical distribution
of power supply on an aircraft, the CAD systems
generate wiring plans. Then the electrical harness
is designed from the wiring plans. A new step
forward needs to be accomplished in order to automatically
design and optimise the harness itself; this is
the expected technical achievement of the FRESH
project. |

The technical research goal of the FRESH project is to focus on new technologies acquisition in order to convert automatically wiring plans into harness simulation.
The project addresses not only CAD designed aircraft but old aircraft as well. For not-CAD designed aircraft, a part of the proposed research will focus on methods to automatically capture paper plans and transfer them in a numerical form, on like CAD. Doing so, the whole fleet of aircraft is taken into account.
Large manufacturers have expressed interest in the FRESH system; they are expecting:
- electrical harness optimisation capabilities
- cost reduction in industrialisation
- cost reduction in modification design and validation
SMEs have as well expressed interest in the progress expected from FRESH. The most concerned ones are those working in the aircraft maintenance sector. The expected benefits are:
- fault free recapture of wirings diagrams
- significant reduction of wasted time, 50% is our target : we consider that the manual recovery of a wiring diagram plan takes several hours or days, according to its complexity.
- error free intervention. Presently, errors are detected most frequently during the installation, what engages extra-costs in overhauling (one error out of a hundred is detected after implementation)
The FRESH expected project aims at increasing the productivity of the design and maintenance teams in charge of the harness by a global 15 %. The aircraft safety level will be kept up without over-cost thanks to the strict verification and validation carried out by the simulation (no reengineering iteration).

EXPECTED RESULTS |
|
|
|
|
Design of an automatic simulation of performance behaviour for the electrical harness. The simulation system will embed all the design phases from the aircraft definition of wiring plans (Computer Aided Design or paper plans) up to the simulated harness.
|
|
Positive impacts are foreseen on the aircraft life cycle cost:
- optimisation and validation of harness design (aircraft design and production cost)
- safety assessment, of the whole cabling, requested modification or enhancement (cost of aircraft modification).
