Additive Manufacturing covers a set of rapidly expanding technologies that have the potential to profoundly transform the way in which the aviation industry develops, manufactures, or maintains its products. . These technologies enable designers to access to new shapes, materials and functions that are unattainable by conventional means. Furthermore, Additive Manufacturing may drive main change in our traditional industries as well as main impacts on business models. To take quickly and fully benefit from additive manufacturing technologies and have an organization able to face these challenges, Safran has decided to create a multidisciplinary competence center dedicated to AM within SafranTech: "Safran Additive Manufacturing”. The proposed presentation will give us the opportunity, to present challenges identified by Safran Additive Manufacturing that will have to be mastered in order to enlarge AM use. These challenges are metallurgical, mechanical, numerical but also Human.

Electroimpact has supplied a wing assembly system for the C919. This system incorporates tooling for the wing box, leading and trailing edges, flaps and aileron. Electroimpact did the work in Mukilteo and Hawarden in the UK. The supplied system takes maximum benefit from automation including two robot drilling systems and two large envelope CNC drilling machines for the wing surfaces. Engineering was generated by Comac and passed to Avic who in turn passed it along to Electroimpact. In order to work closely with the customer Electroimpact opened a support office in Yanliang. Chinese engineers were recruited from universities in the USA and worked on the project in Mukilteo and Hawarden for two years. Then they relocated to Yanliang, China to represent the company at the customer’s doorstep.

Starting from the analysis of the actual operation of ARJ21, the presentation will focus on the solution to the maintenance problems faced by new model aircraft in the initial operation stage. The presentation will discuss an evaluation system built on characteristics and development need of enterprises with continuous analysis and monitoring functions. It dynamically inputs scientific information instruction into enterprise organizational structure and provide scientific basis for enterprises’ decision-makers. The presentation calls for an aircraft structural management system to lay a solid foundation for the future development of aircraft intelligent health management system.

Building IMA system configuration is one of the major tasks for IMA integration. It involves supplier requirement capture, system configuration and verification. To mitigate the increase in aircraft system complexity and short development schedules, AVIAGE utilizes the Model-Based System Engineering (MBSE) technology to overcome the challenges. This presentation will introduce the practice of applying MBSE to build IMA system configuration for C919. It will introduce how AVIAGE utilizes the model-centralized approach in the life-cycle phases for IMA system configuration development, including establishing and managing the system model, capturing customer requirements and conducting system impact analysis, generating configuration artifacts and verifying them. Future challenges and potential solutions will be also outlined and discussed.

Heavy Duty regulation Euro VI step C and the product being produced accordingly is judged by China VI drafting committee as not sufficient for China. Presented will be the drafting committee proposed increment from Euro VI step C -> China VI. The whole emission area will be covered but Special focus will be on the OBD related increments. Highlighted will also be some area were fundamental technical OBD related challenges is expected as result of China VI.

Turbocharged engines can suffer from poor transient performance at different load and speed ranges. This leads to increase in engine-out exhaust emissions primarily particulate matter and NOx and poor drivability after a positive change in speed or load. Fast and accurate response of the boost pressure control system during transient conditions is a fundamental factor to solve this issue. A slowly responding system can considerably increase emissions. The magnitude of which is dependent on the dynamics of the driving profile. An adaptive method of diagnosing a slow responding boost system is proposed in this presentation. It uses real-time evaluation of the driving profile to assess the health of the boost pressure control system during transient conditions.

In their latest regulation, CARB requires all inputs into the propulsion system to be audited and classified. One of the areas that is receiving scrutiny is the safety related inputs from the chassis control system. This presentation provides a methodology to analyze the system, and determine a systems classification for some common chassis functions.

The presentation will show the performance of soot sensors from 3 different suppliers when used to monitor the status of a DPF. This presentation is a sequel to a presentation made by Ricardo at the March 2015 SAE OBD Symposium, in Stuttgart. The generic DPF OBD monitoring technique presented at the 2015 Symposium will form the basis for comparative analysis of the sensors. A discussion will be made on the effectiveness of each sensor in terms of the quality of the signal provided, the robustness of the resulting judgement metric, and observations on the use of each sensor from a practitioner's standpoint. The presentation will also provide comments on the effectiveness of the generic OBD monitor used to benchmark the sensors.

Cyber-attacks, such as intrusion and manipulation can cause malfunctions that affect the safety of a road-vehicle or non-road mobile machine. According to the Global Technical Regulation No.5 of the United Nations (UNECE), it is the job of OBD to detect failures that affect the environmental or safety performance. Thus, a cyber-attack that affects the safety should be detected by the OBD system.
