Faced with a lack of domain expertise and internal resources, an aviation technology provider asked EASi to review designs, analyze failure cases and recommend design solutions for its avionics controller.
Reliability plays a major factor in the competitive world of advancing technology and is the highest-priority requirement in the aerospace industry. Companies that develop avionics systems use a plethora of techniques to make sure their products are reliable even at altitudes of 50,000 feet. Typically, product reliability measures are defined and addressed from the beginning of and throughout the design lifecycle. These measures include reliability prediction techniques that involve mathematical calculations and methodologies for analyzing the life and quality of products.
The client and challenge
The client is a high-end technology provider that develops aircraft engine systems and controllers. It is the world leader in the aircraft industry and has brought the latest technologies to its avionics systems.
The client was developing a new aircraft controller system that was complex and had many electromechanical and software components, external sensor inputs, controls and coils. During the initial phase of development, the client needed to verify the reliability and robustness of the initial design. Due to a lack of domain expertise and internal resources, the client sought out an engineering consultant to review designs, analyze failure cases and recommend design solutions.
The review scope included:
The EASi solution
EASi provided a reliability analysis solution based on military and aerospace safety standards. A multi-stage product analysis approach was applied, which involved:
EASi delivered in-depth analysis reports for design, schematic, PCB layout, reliability and FTA, which have given this client deep confidence in the reliability of its new system design. EASi completed all phases of this project ahead of schedule by conducting weekly tracking touchpoints with the client during which activities, key updates, open items and design changes were discussed and reviewed. Additionally, the proper documentation that EASi aggregated was a huge value-add to the customer, as quality and compliance considerations are held in high regard in the aerospace and defense industry.
The documentation gathered included a detailed system-level reliability report, fault tree analysis report, electrical design recommendations and changes and a software static analysis report. We exceeded client expectations in each phase by providing detailed analysis results, additional inputs and value additions. Most specifically, we were able to provide a 0-100 degree Celsius temperature report, which provided a deeper insight into the product’s reliability analysis. This prototype has since been completed and is expected to launch on the market by the end of 2019.
