  • Judt, David; Forster, Kevin; Lockett, Helen L.; Lawson, Craig P.; Webb, Philip (Society of Automotive Engineers, 2016-09-27)
    In the civil aircraft industry there is a continuous drive to increase the aircraft production rate, particularly for single aisle aircraft where there is a large backlog of orders. One of the bottlenecks is the wing ...
  • Lockett, Helen L.; Arvanitopoulos-Darginis, K. (Elsevier, 2017-05-09)
    Design for maintainability is an important aspect of aircraft design, with maintenance representing 10 – 25% of the direct operating cost of an aircraft [1]. Design for Maintainability incorporates many aspects including ...
  • Guenov, Marin D.; Libish; Tang, Dunbing; Lockett, Helen L. (2006-12-01)
    In the conceptual design phase, relatively simple equations and functions (or compiled code) are used to describe the aircraft and to perform trade-off studies. The latter require an optimal execution sequence in order ...
  • Mehnen, Jorn; Ding, J.; Lockett, Helen L.; Kazanas, P. (2010-04-19)
    Additive Layer Manufacture (ALM) is a technique whereby freeform structures are produced by building up material in layers. RUAM (Ready-to-Use Additive Layer Manufacturing) is an innovative concept for building large ...
  • Hussain, Romana; Lockett, Helen L.; Annamalai Vasantha, Gokula Vijaykumar (Elsevier Science B.V., Amsterdam., 2012-05-01)
    Both the Product-Service System (PSS) literature and industry express a need to close the design loop by using product-in-use data to inform PSS Conceptual Design. Nevertheless, how to actually accomplish this is largely ...
  • Lockett, Helen L.; Guenov, Marin D. (Elsevier Science B.V., Amsterdam., 2005-02-01)
    This paper presents a novel CAD feature recognition approach for thin-walled injection moulded and cast parts in which moulding features are recognised from a mid-surface abstraction of the part geometry. The motivation ...
  • Li, Tao; Lockett, Helen L. (Elsevier, 2017-05-09)
    Modern aircraft are more integrated with advanced systems functionalities, which result in ever-increasing aircraft complexity, further development difficulties and development delays. These system complexities are mostly ...
  • Guenov, Marin; Lockett, Helen L. (Design Society, 2007)
    In today's competitive market many consumer products are designed with complex curved shapes to meet customers' demands for styling and ergonomics. These styled products are commonly manufactured using moulding processes ...
  • Lockett, Helen L. (Cranfield UniversitySchool of Engineering, 2005-07)
    This thesis presents a knowledge based manufacturing advisor for Computer Aided Design. The aim of the project has been to develop techniques that can help designers to evaluate the manufacturability of moulded parts ...
  • Lockett, Helen L.; Johnson, Mark; Bastl, Marko; Evans, Stephen (MCB University Press, 2011-03-01)
    Purpose - In recent years there has been increasing interest in Product Service Systems (PSS) as a business model for selling integrated product and service offerings. To date there has been extensive research into the ...
  • Lockett, Helen L.; Fielding, John (2005-10-27)
    Post-graduate education in aircraft design needs to prepare students for their future roles as professional engineers in the aerospace industry. A key requirement from industry is for students to learn how to deal with ...
