The Bloodhound Guided Missile and the Hawker Harrier “Jump Jet”
Draft for joint Herbert Simon Institute/Manchester Institute of Innovation Research Seminar, 1st April 2011 Practice in Communities: how engineers create solutions ‐ the Bloodhound Guided Missile and the Hawker Harrier “jump jet”. Jonathan Aylen* and Mike Pryce* Manchester Institute of Innovation Research Manchester Business School University of Manchester “Every aeroplane is different ‐ a self‐optimising shambles” Ralph Hooper, Harrier project designer Aerospace engineers face the task of developing a project from overall design concept through to working prototype and on into sustained use. Engineers often work in small groups when developing an initial concept. Once the basic concept has been agreed they may work in similarly small groups, or as part of larger teams to develop key components of a system. At this stage key design tasks are defined and delegated and then the resulting components are tested and integrated to build a prototype (Vincenti, 1990). Individual sub‐assemblies are usually developed in parallel. So, aeronautical engineering is often seen as a cyclical process of analysis and synthesis, although in practice it is seldom so neat and linear, as the opening quote from a leading practitioner, Ralph Hooper, illustrates. The nature of engineering design is complex, with designers having to cope with many systems and components interacting in dynamic ways. The breadth and depth of knowledge required means no one person can carry out all the tasks of engineering design. Group or team working is essential. Engineering design is an innately social activity. However, mastering the specific skills of any one discipline, and also learning how to utilise the knowledge gained within the group or team, often depends on the abilities of key individuals. -

We’re on the www. Thanks to Don Taylor the MAAA has now its own individual Internet web site. Look us up on www.aussiemossie.asn.au. Don has slaved over a hot PC for many nights teaching himself how to undertake the task, and the result as you will see is a credit to him. He welcomes all feedback, as well as genuine articles that are unique, as he does not want the site to be just another list of numbers but wants to have articles that portray the human side as well. You can email him with your anecdotes via the Contact Us section on the site. Our thanks also go to stalwart Brian Fillery for making his personal site available to the MAAA for the past few years. It was greatly ap- preciated. By the way if you are look- ing for the home page, there is not one, it is now known as the Hangar page (Don’s humour—you can tell by the smirk on his face).

Cluster Weapons – Military Utility and Alternatives
FFI-rapport/2007/02345 Cluster weapons – military utility and alternatives Ove Dullum Forsvarets forskningsinstitutt/Norwegian Defence Research Establishment (FFI) 1 February 2008 FFI-rapport 2007/02345 Oppdrag 351301 ISBN 978-82-464-1318-1 Keywords Militære operasjoner / Military operations Artilleri / Artillery Flybomber / Aircraft bombs Klasevåpen / Cluster weapons Ammunisjon / Ammunition Approved by Ove Dullum Project manager Jan Ivar Botnan Director of Research Jan Ivar Botnan Director 2 FFI-rapport/2007/02345 English summary This report is made through the sponsorship of the Royal Norwegian Ministry of Foreign Affairs. Its purpose is to get an overview of the military utility of cluster munitions, and to find to which degree their capacity can be substituted by current conventional weapons or weapons that are on the verge of becoming available. Cluster munition roughly serve three purposes; firstly to defeat soft targets, i e personnel; secondly to defeat armoured of light armoured vehicles; and thirdly to contribute to the suppressive effect, i e to avoid enemy forces to use their weapons without inflicting too much damage upon them. The report seeks to quantify the effect of such munitions and to compare this effect with that of conventional weapons and more modern weapons. The report discusses in some detail how such weapons work and which effect they have against different targets. The fragment effect is the most important one. Other effects are the armour piercing effect, the blast effect, and the incendiary effect. Quantitative descriptions of such effects are usually only found in classified literature. However, this report is exclusively based on unclassified sources. The availability of such sources has been sufficient to get an adequate picture of the effect of such weapons. -
2021-03 Pearcey Newby and the Vulcan V2.Pdf
Journal of Aeronautical History Paper 2021/03 Pearcey, Newby, and the Vulcan S C Liddle Vulcan to the Sky Trust ABSTRACT In 1955 flight testing of the prototype Avro Vulcan showed that the aircraft’s buffet boundary was unacceptably close to the design cruise condition. The Vulcan’s status as one of the two definitive carrier aircraft for Britain’s independent nuclear deterrent meant that a strong connection existed between the manufacturer and appropriate governmental research institutions, in this case the Royal Aircraft Establishment (RAE) and the National Physical Laboratory (NPL). A solution was rapidly implemented using an extended and drooped wing leading edge, designed and high-speed wind-tunnel tested by K W Newby of RAE, subsequently being fitted to the scaled test version of the Vulcan, the Avro 707A. Newby’s aerodynamic solution exploited a leading edge supersonic-expansion, isentropic compression* effect that was being investigated at the time by researchers at NPL, including H H Pearcey. The latter would come to be associated with this ‘peaky’ pressure distribution and would later credit the Vulcan implementation as a key validation of the concept, which would soon after be used to improve the cruise efficiency of early British jet transports such as the Trident, VC10, and BAC 1-11. In turn, these concepts were exploited further in the Hawker-Siddeley design for the A300B, ultimately the basis of Britain’s status as the centre of excellence for wing design in Airbus.
