Universal connectors for joining stringers

Harrison, Jr., Ernest · NASA Technical Reports Server (NASA)

This invention is a lightweight, universal connector that joins stringers at various angles. The connectors 10 are fabricated from fiber-epoxy resin strips that wrap around stringers 30 and have ends, tabs 16 and 18, which extend in one general direction. The inside surface of the first tab 16 lies on a plane defined by the stringers being joined, and the second tab 18 is separated from the first tab 16 by a distance equal to their thickness. Stringers 30 of different shapes and sizes are joined by alternately bonding the first tab 16 of one connector between the first 16 and second 18 tabs of another connector. Tee-joints are formed by using web elements 41 and 42 which each partially wrap around a stringer 3010 and have tabs 411 and 421 which are offset, and are bonded between tabs 16 and 18 of universal connectors 109 and 1010 bonded to another stringer 309. Sharp corners are trimmed from the tabs so that a gusset area remains between the stringers for support. Acute angle through obtuse angle joints are formed by trimming those edges of the tabs which lie against the stringers. A specific application of the invention is a Walker 60, utilized by handicapped individuals, fabricated from composite materials that is 40% lighter than similar metallic structures.

Stringers and the Journalistic Field

Nimmagadda Bhargav · 2023

This book is one of the first ethnographic works on small-town stringers or informal news workers in Indian journalism. It explores existing practices and cultures in the field of local journalism and the roles and spaces stringers occupy. The book outlines the caste, gender, class and region-based biases in the production of Indian-language journalism with a specific focus on stringers working in Telugu dailies in small towns or ‘mofussil’ areas of Andhra Pradesh and Telangana, states in south India. Further, it captures their daily work and processes of news production, and the precarious lives they often lead while working in small towns or mofussils. The author, by using Bourdieu’s field theory, introduces the journalistic practices of stringers working on the margins and how they negotiate the complex hierarchies that exist within the journalistic field and outside it. This book will be of great interest to scholars and researchers of ethnography, media sociology, journalism and media studies, labour studies and Area studies, especially South Asian studies.

Hydrodynamic Shape of Oil Stringers: ABSTRACT

I. Lerche Z. He · AAPG Bulletin · 1989

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.

Analysis and optimization of composite stringers

Badalló i Cañellas, Pere · RECERCAT (Consorci de Serveis Universitaris de Catalunya) · 2015

The use of the stiffened panels in the aircraft/aeronautical industry has been growing in the last decades. On the other hand, the exponential growth in the use of composite materials in the last years has had a strong2/2influence in these structural components and in the industry in general. In consequence, with this new material unknown characteristics appear, for example new failure mechanisms, producing high complexity when simulation, analysis and testing are performed. For this reason, thanks to the increment in the power of the computers, the use of virtual tests with finite element method has become crucial in the simulation of the components with high structural responsibility. In the same way, the general spread of computational resources has made possible the use of optimization methods in the design process of stiffened panels. Optimization methods are able to find the best design according to some criteria, by modifying different parameters

Hydroforming of Laser Welded Sheet Stringers

Metin Ertuǧrul, Peter Groche · Key engineering materials · 2009

The hydroforming of sheet metals belongs to deep drawing processes, where the forming capacitiy is performed by a pressure medium. This process is especially suitable for parts with a non-rotationally symmetric geometry. Light-weight structures require particularly weight optimized geometries with a possibility to attach joints or secondary shape elements. Weight and strength optimised structures often use stringer elements to fulfill this requirement. They are used in flat plates or in single curved bodies. The assembling of the sheet stringers is often costly in terms of time and money. Hence, the hydroforming process of those sheet stringers offers a new process chain for the manufacturing of complex, multi-curved hollow parts with pre-attached stiffeners. Thereby, tools and process control strategies are similar to the conventional hydroforming process of blank sheets. This paper describes the hydroforming process of laser welded sheet stringers. It gives a first outline of the potential and the limitations of the new process chain. Blank holder force and the fluid pressure are the main parameters during the hydroforming process.

A NEW MANUFACTURING PROCESS OF STRUCTURAL AERONAUTICAL STRINGERS FROM STRAIGHT STRINGERS USING AN ADAPTATIVE MOULD

IMANOL ANSOLA ARIZMENDIARRIETA, Natalia G. Pérez-de-Eulate, IBAI BERROTARAN SAAVEDRA et al. · DYNA · 2020

A new process of dry carbon fibre fabrics (NCF's) preforming has been developed for composite stringers of aeronautical structural parts using an adaptive mould. The new process consists of straight stringer preform manufacturing of known section in a conventional way, applying tensions, deformations and variations of pressure and temperature by means of an adaptive mould to achieving the final geometry. This preform will be consolidate by liquid moulding. The behaviour of the preform will be evaluated analysing the formation of wrinkles both internally and externally. Finally, a new prototype has been designed and manufactured and the automation of this new process has been initiated.
