The existing fastener installation operations account for drilling and bolting a large number of holes through the wing skin. Because of its inherent complexity, these operations are prone to costly defects. Consequently, there is room for improvement and optimisation. Instead of focusing on expensive, complex and high-risk automation solutions, visual aid has proven to be a more suitable option. Particularly, optical projection would display operations information directly on the wing skin. This would grant the operators the help they need to cut down on defects and remove the need to follow large slaving maps, simplifying their tasks. Therefore, the aim of this project is to introduce and install this technology, which will display hole positions and its related operation information. Coupled with the system’s flexibility to display any shape and colour, this solution will be robust enough and fit for purpose to support these production operations. After a comprehensive market research to select the best technology, the selected option was programmed and optimised to perform in an Airbus environment and to satisfy Airbus’ requirements. The…

Lean Manufacturing is generally a challenge across all manufacturing companies. Especially in the aerospace industry where production costs have a significant impact on the overall business success. Additionally, the aircraft Takt time is gradually being reduced to accomplish ramp up requirements. The hydraulic system tests are considered as a production waste (Muda Type I) since it is mandatory but does not add any value to the end customer. Furthermore, due to health and safety aspects, no other production task can be done while the test is being performed. This research project aimed at performing a Kaizen analysis of the hydraulic system test stations to reduce or eliminate idle time while it is taking place. To do so, an extensive literature review has be conducted to provide its research framework. Then, all the project requirements and constraints were identified in order to generate a design specification. As a part of the methodology, several design proposals to accomplish this specification are created. In parallel, a reverse engineering case scenario is used to generate a DMU using a…

NDT Application from Conventional to Digital Radiography for the Aircraft Maintenance Industry

SORT Engineering GmbH-Adel A. Ghobbar

To be published on 2019-09-16 by SAE International in United States
Technological innovation can provide improved productivity, increased cost savings, and it can keep or make an organisation competitive. Digital radiography for non-destructive testing (NDT) is such a promising innovation. In organisations with large scale utilisation of non-destructive testing, a transition from film to digital radiography is easily justified. Nevertheless, this is not the case for every organisation. Next to the operational workflow, system flexibility, quality, and regulatory issues also play a role in the trade-off. Especially in the aircraft maintenance industry, where the non-destructive operation is related to a lot of different factors. Motivated by the developments of digital radiography, the NDT department of KLM Engineering & Maintenance (E&M) requested advice in reconsidering their conventional film radiography capabilities. The objective of this research was to assess the feasibility of digital radiography at KLM E&M. First, a thorough understanding of the technical and practical principles behind conventional radiographic testing was built up. Regulatory and process requirements were identified and several digital radiographic systems for industrial purposes were analysed. Based on the requirements, only computed radiography (CR)…

Step & Repeat: Reduce Derivative Aircraft Development Risk with Design Reuse

To be published on 2019-09-16 by SAE International in United States
Designing derivative aircraft is a complex process with potentially large amounts of program risk. In this paper we present new technologies such as digital interface control documents, and generative design that can transform this process. Employing these types of technologies makes the process more verifiable and repeatable. The paper explains how the technologies can be adopted from the early definition of components & LRUs, to their aggregation into reusable subsystems, as well as the automation and validation processes that can be built around them to reduce the associated complexity and program risk.

Martinair is based on Schiphol Oost and is part of the KLM Group since 2008. The KLM Group on its turn is part of the Air France – KLM Group. Martinair started as a charter company and was founded by Martin Schröder. Martinair is now a cargo operator with its own maintenance base at Hangar 32 on Schiphol Oost. It operates 7 McDonnell Douglas MD-11’s and 6 Boeing B747-400’s. The focus will be on the MD-11 tri-jet in this thesis. Due to the entry in the KLM Group in 2008, changes have been made for synergy reasons to the Martinair organisation. Martinair Maintenance and Engineering is now focussing on becoming a Regional Jet Center. The maintenance on the Embraer E-190 of KLM Cityhopper will be the main part of the work. Due to the new focus of the Martinair maintenance and engineering department, the maintenance capacity for a MD-11 A-check will no longer be available. It is therefore chosen to outsource the MD-11 A-check from Martinair maintenance and engineering to KLM engineering and maintenance. The…

Reconfigurable Jig Tooling and In-Process Metrology for High Accuracy Prototype Compound Helicopter Wing Assembly

University of Nottingham-Richard J. Crossley
  • Technical Paper

To be published on 2019-09-16 by SAE International in United States
This paper documents the potential use of reconfigurable reusable jig tooling based on the box-joint system for use in the assembly of a prototype compound helicopter wing. Due to the aircraft configuration the wing design is pinned at both ends and therefore requires a higher degree of accuracy (typically 0.2mm), over the 4m length, than conventional wings. In this paper the cost benefit of reusable tooling in a low volume prototype scenario is examined followed by the design of the jig and location features to enable accurate build and metrology documentation. A prototype 4m test jig comprising of commercially available components and bespoke machined ‘pick-ups’ is presented here. Hardware and measurement process cost modelling is documented along with results for the positional and hinge-line concentricity setting accuracy that was achieved using a laser tracking system. Subsequent measurements over a 24hr period are also discussed along with potential sources of the observed reduction in jig accuracy over time.

Optimisation of assembly processes for Adhesive bonded Brackets onto the airframe structure

Aircraft manufacturers use adhesive bonded brackets (ABB) to support wire harnesses, looms and sensors. Using ABBs eliminates the necessity to drill holes in the airframe and significantly reduces the assembly time. Such brackets are installed manually on the airframes in numerous locations using high strength epoxy based adhesives. In addition, the application of adhesive onto bracket is carried out manually. Thus it's time consuming and quality relies on operator’s skill sets to apply a certain quantity of adhesive using a predefined pattern, both of which are commonly not controlled. On the other hand, removing the damaged brackets by manual operations tend to cause dents and scratches in metallic airframes and delamination in composites. Prior research indicates that the brackets can be removed by heating them. But, they are not recommendable to aerospace manufacturers due to the longer process times. Therefore, it is vital to find a solution or methods to remove the ABBs without damaging any airframes. The scope of this research encompasses all the areas of design, technology and product development enabling a multi-disciplinary…

Concept of Modular and Reconfigurable Electronic Warfare System (EWS) Suite

AIRBUS Helicopters-Davide Baccello
  • Technical Paper

To be published on 2019-09-16 by SAE International in United States
A new concept of standardized EWS suite is proposed in order to match the different operational needs and the several platform constrains. The idea is do have an EW controller, connected with the core mission able to manage and reconfigure the suite depending to the sub-systems selected for the specific integration w/o H/W changes (except for the sensors identified for the installation). The full suite has to be qualified for all the platform classes (most demanding has to be considered) in order to avoid re-qualification/certification activities each time that new installation is required. The level of modularity is depending to the requirements allocated to the EWS suite and/or to the operational needs. The EWS suite is managing passive and active (countermeasure) subsystems connected with the controller by serial standards. Electronic System Measurement (ESM), Radar Warning Receiver (RWR) and Laser Warning Receiver (LWR) are just few example of passive subsystems that can be supported by the Suite as for active like: Chaff and Flares Dispenser System (CFDS) and Direct IR Countermeasure System (DIRCM). Only one modular…

Outdoor geolocation has been widely implemented and enhanced by using the Global Positioning System. However, the inefficiency of this technology for indoor geolocation purposes has required the development of new solutions. As part of a global digitalisation strategy, the geolocation and tracking of drilling machines, tooling and jigs is a real challenge for Airbus in manufacturing environments. By understanding the current practices in Airbus Broughton factory and analysing current uses of indoor geolocation technologies, this paper aims to develop a geolocation system for machines and tooling and to consider its benefits and issues from both operational and financial views. The successful deployment of geolocation technology relies on a robust system with high accuracy and reliability in data transmission. The benefits for future manufacturing and supply chain improvements, as well as quality enhancement and cost reduction, will highly contribute to operations traceability and to the development of the next generation of aircraft.
