Abstract

A two‐stage gas gun has been built at British Aerospace's Sowerby Research Centre, Filton, Bristol. The gas gun, a company investment in a high technology future, is used as a tool in a materials research programme to study the physics of hypervelocity impact. It is unique for its size and versatility and can be ‘fired’ up to five times per day in tests presently being conducted with one gramme projectiles striking targets at velocities up to 3.2 km/second.

Abstract

Purpose

The purpose of this paper is to find the optimum configuration of the composite launch tube currently being developed in Roketsan. The winding thicknesses and winding angles of the launch tube are selected as design variables, and three different composite material alternatives are evaluated: glass/epoxy, carbon/epoxy and aramid/epoxy.

Design/methodology/approach

In this study, structural optimization of a composite launch tube of man portable air defense system is conducted. To achieve a cost-effective design, a cost scoring table that includes structural weight, material cost, availability and manufacturability is first introduced. Then, optimization for minimum weight is conducted, where the winding thicknesses and winding angle are taken as design variables, and the safety factor value obtained by using the Tsai–Wu damage criterion is used as constraint. A surrogate-based optimization approach is used where various options for surrogate models are evaluated. Glass/epoxy, carbon/epoxy and aramid/epoxy are considered as alternative materials for the launch tube. Finally, the selection of the most cost-effective design is performed to achieve optimum cost.

Findings

Carbon fiber-reinforced epoxy matrix material provides the optimum cost-effective design for the launch tube.

Practical implications

The findings of the paper can be used to design more cost-efficient composite launch tube currently being developed in Roketsan.

Originality/value

The existing studies are based on a design approach to achieve minimum weight of the launch tubes, whereas this study introduces a design approach to achieve optimum cost.

Abstract

Purpose

The purpose of this paper is to highlight current changes in the way people communicate, and the role of You Tube in leading these changes

Design/methodology/approach

The approach takes the form of the author's observations and reflections.

Findings

With close to 100 million examples online, and growing exponentially, You Tube, and short video in general, are dramatically affecting the way in which today's Americans – especially young people – communicate and learn. In only five years, short video has moved from a medium for isolated, perhaps geeky young people to express themselves, to a two‐way medium used by mainstream people all over the world – including many experts and intellectuals – to share information and ideas. Today so much information is shared through video that, for perhaps 80 percent of Americans, reading and writing are rarely used skills, and becoming even more so.

Practical implications

While it is admitted that there remains a (relatively small) group for whom reading and writing will continue to be important, the question is “Should we continue to struggle to teach reading and writing to the great percentage of students, or should we focus on teaching clear communication of ideas through media that are easier to use?”

Originality/value

The paper provides a new perspective on the meaning of communication and the role of textual literacy in life and education in the near future.

Abstract

This case describes the journey of a Doctor from curiosity to product formulation to enterprise promotion and presents the problems faced by him in succeeding commercially. The innovator perceives the innovation to be a medical success and a commercial non startec. The case provides an opportunity to evaluate the efforts of Dr. Shah and propose a strategy for the future.
