A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants
ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.

Similarity Assessment of the Engineering Concepts: Decision‐Making Support and Metrics
ABSTRACT The new product development (NPD) process is a systematic approach to bring new products and innovations to market. Nowadays, this process is affected by a number of influencing factors associated with the fast‐paced technological changes. One of those factors is the distributed design nature of product development activities: team members are

Compression‐Expansion: Miniaturization, Modularity, and Logistics Beyond Earth
ABSTRACT If the Cold War space race culminated in a return to Earth, at present we are experiencing a renewed interest in space. Drawing on fieldwork among people working in the space sector in Sweden, this article focuses on some of the imaginaries underpinning this resurgence and the contemporary commercialization of space. Specifically, I hone in on
