The testing pyramid is mandatory for the development and certification process. This framework encompasses tests ranging from materials (coupons) to components, structural elements, and systems to full-scale testing.
Aerospace test pyramid
High precision for a safe take-off
Subcomponent testing
Structural subcomponents for the fuselage, wings, and tanks are qualified after different static and dynamic tests, such as fatigue testing.
Element testing
Testing construction elements and their subcomponents under specific loads and conditions is essential to meet damage tolerance requirements.
Coupon testing
Coupon or material testing is essential for understanding the behavior of materials under specific mechanical loads, particularly during standardized assessments such as tensile, compression, and shear tests.
Full scale testing
Structural testing evaluates an aircraft’s strength, durability, and reliability under operational stresses.
Component testing
Component testing involves evaluating individual parts to assess their performance and functionality under realistic conditions.
The mandatory nature of aerospace testing is evident through the prototype and development phase and during the certification process of new aircraft and their associated products. To ensure strict safety regulations and compliance, a multi-tiered testing framework, often called the test pyramid, evaluates materials, components, and structures using mechanical and virtual assessments.
This white paper emphasizes the importance of aircraft safety, reliability, and performance and outlines an approach that begins with material assessments progresses through component evaluations and culminates in full-scale tests. The framework aims to minimize risks and validate new designs, encouraging innovation while maintaining high-performance standards in the aerospace industry.
We invite you to explore the intricacies of aerospace testing and certification in this comprehensive whitepaper.
