Abstract
Purpose
The lightweight design of aircraft seats can significantly improve fuel efficiency and reduce greenhouse gas emissions. Metal additive manufacturing (MAM) can produce lightweight topology-optimized designs with improved performance, but limited build volume restricts the printing of large components. The purpose of this paper is to design a lightweight aircraft seat leg structure using topology optimization (TO) and MAM with build volume restrictions, while satisfying structural airworthiness certification requirements.
Design/methodology/approach
TO was used to determine a lightweight conceptual design for the seat leg structure. The conceptual design was decomposed to meet the machine build volume, a detailed CAD assembly was designed and print orientation was selected for each component. Static and dynamic verification was performed, the design was updated to meet the structural requirements and a prototype was manufactured.
Findings
The final topology-optimized seat leg structure was decomposed into three parts, yielding a 57% reduction in the number of parts compared to a reference design. In addition, the design achieved an 8.5% mass reduction while satisfying structural requirements for airworthiness certification.
Originality/value
To the best of the authors’ knowledge, this study is the first paper to design an aircraft seat leg structure manufactured with MAM using a rigorous TO approach. The resultant design reduces mass and part count compared to a reference design and is verified with respect to real-world aircraft certification requirements.

Abstract
Purpose
This paper aims to examine the relationship between perceived organizational support (POS) and work-life balance (WLB) in the context of the Indian banking sector and their subsequent impact on the commitment level of employees.
Design/methodology/approach
Data were collected from 617 banking employees holding different positions with a structured adapted questionnaire. The data analysis was done using structural equation modeling.
Findings
The results revealed a positive influence of POS on WLB. Moreover, this relationship has been found to be partially mediated by organizational commitment (OC).
Originality/value
This study augments the organizational behavior domain by identifying and empirically validating POS as an antecedent of WLB and OC as its consequence in the context of the Indian banking sector, where such studies are scant. The study also suggests the managerial and theoretical implications based on the findings.
