CBM Fastener Sector visits Airbus
Report by Dr John Newnham
At a Fastener Engineering Research Association seminar held
in November, Bill Eccles, of Bolt Science Ltd, gave a
presentation on the theory and testing of vibration resistance
in nuts and bolts, and showed how the standard aerospace and
industrial tests differed. Bill is a leading fastener engineering
consultant, currently engaged in research leading to a PhD on the
subject of vibration resistance.
He presented interesting views of what caused bolts and nuts to come
loose. The most plausible theory is that vibration itself does not cause
loosening, but the transverse movement between the bearing face of
the fastener and the joint. The most common industrial and
automotive test for vibration resistance (the Junker test) applies
repeated transverse force.
The seminar continued with a presentation on two successful
products for preventing loosening by very different means. The first
was on the properties and industrial applications of the Loctite
range of products, given by Bob Orme and Colin Chapman of
Henkel Loctite. Following that, Rodney Cross of Cross
Manufacturing Co described a novel thread insert with the
Spiralock thread form, which allows bolts to be installed in a freespinning
mode, and only locks the thread when tightened. This
product has good re-usability, and has found applications in very
demanding helicopter bolting. Both Loctite and the Cross
Spiralock insert give excellent performance in the Junker Vibration
Machine.

Developing & Implementing Proactive Cost & Fuel Efficient Strategy
Active Communications’ Efficiency in Aviation forum will provide a unique platform for senior executives from the aviation
industry to discover, consider and discuss innovative management, operational and technical strategies to achieve greater cost
and fuel efficiency.
THE AGENDA
Throughout the 2 days you will have the opportunity to hear from your industry peers and
evaluate the latest solutions:
• Discover the most effective cost management strategies being implemented in
the industry
• Understand the best measures to optimise fuel efficiency both in flight and on the
ground
• Examine the outlook for the global aviation industry and the future of fuel prices,
supply and demand
• Consider the potential impact of improvements in air traffic control
• Learn the latest fuel efficient aircraft and engines in research, development and
production
• Determine the advantages and disadvantages of fleet replacement under the
current climate and also study various leasing options
AN INTERACTIVE 2 DAYS
Active Communications’ meetings offer the perfect opportunity to discover the latest
updates and discuss your own challenges and solutions with your peers through an
interactive and informative 2 day programme.
• Hear from an outstanding line-up of the industry’s leading executives.
• Network informally with a relatively small, targeted group of senior-level experts and
decision-makers from the aviation industry.
• Learn more about your peers’ key business strategies, research and development.
• Discuss the latest challenges and developments in this increasingly important area.
• Participate in roundtable sessions – giving you the chance to discuss the latest issues
with your colleagues – and the speakers - in an open, informal and intimate setting.
Who will attend?
All Active Communications’ events attract a targeted group of senior level decision-makers and
researchers from industry. Our meetings are strictly end-user focused. Only a select group
of companies are invited to sponsor the event to ensure the emphasis is on the industry
participants, and making sure our delegates have a valuable and positive experience.
Delegates will be drawn from national, regional and international commercial airlines, and
technology and service providers including Presidents and CEOs as well as Senior Vice
Presidents, Executive Vice Presidents, Directors and Managers of: Finance, Investment,
Commercial Strategy, Flight Operations, Ground Operations, Engineering and Technology.
