Journal of Aeronautical History, 2018 (07). pp. 200-207. http://repository.nms.ac.uk/2121 Deposited on: 17 September 2018 NMS Repository – Research publications by staff of the National Museums Scotland http://repository.nms.ac.uk/ Journal of Aeronautical History Paper 2018/07 People and Planes: Technical versus social narratives in aviation museums Ian Brown Assistant Curator of Aviation, National Museums Scotland Abstract Redevelopment of two Second World War hangars at the National Museum of Flight in East Lothian provided an opportunity to re-interpret the museum collections. This short account of the project looks at the integrated incorporation of oral history recordings. In particular, it looks at the new approach taken to the interpretation of the museum’s Messerschmitt Me 163B-1a Komet rocket fighter. This uses oral histories from the only Allied pilot to make a powered flight in a Komet, and from a Jewish slave labourer who was forced to build aircraft for Nazi Germany. This focus on oral history, along with an approach to interpretation that emphasises social history, rather than technology, has proven popular with visitors and allowed the building of audiences. 1. INTRODUCTION Traditionally, transport museums and collections have focused on the technological history of their objects, producing Top Trump displays which look at the fastest, biggest, most mass-produced, etc. Colin Divall and Andrew Scott noted in 2001 that ‘transport museums followed some way behind other sorts of museums in dealing with social context.’ 1 These displays often include great detail about the engines and their performance, sometimes including extreme technical detail such as bore size, stroke length, etc. -

Artifacts and Aircraft
International Journal of Business, Humanities and Technology Vol. 5, No. 2; April 2015 The Ancients: Artifacts and Aircraft Susan Kelly Archer, EdD Embry-Riddle Aeronautical University Department of Doctoral Studies College of Aviation Daytona Beach, Florida USA Abstract Throughout literature and other art forms, certain themes appear repeatedly. The same might be said for engineering designs, specifically the design of aerospace vehicles. In 1996, Lumir Janku wrote about a set of artifacts, discovered in Peru and determined to be Pre-Columbian, that can be interpreted as models of delta- winged fliers. The design of the Peruvian artifacts has been interpreted in multiple ways by a variety of professionals. The delta wing was also incorporated into the design of civilian aircraft during the 20th Century. Modern delta-winged aircraft were used successfully in both military and civilian applications for more than 40 years. It is interesting to read about the possibility that this aeronautical design may have originated millennia earlier with a culture that did not leave written records to explain its artifacts crafted in gold. Keywords: aviation history, delta wing, Pre-Columbian artifacts Throughout literature and other art forms, certain themes appear repeatedly. The same might be said for engineering designs, specifically the design of aerospace vehicles. Man’s fascination with how birds fly can be linked to the ancient legends of Daedalus or the winged Egyptian gods, and then more recently to John Damien’s attempt to fly with wings made from chicken feathers (Brady, 2000) or Otto Lillienthal’s essays linking the physiology of birds to the design of early gliders (Lillienthal, 2001). -

(Robert W. MacCormack) I certify that I have read this dissertation and that, in my opinion, it is fully adequate in scope and quality as a dissertation for the degree of Doctor of Philosophy. (Gianluca Iaccarino) Approved for the University Committee on Graduate Studies. iii Abstract In developing the next generation supersonic transport airplane, two major challenges must be resolved. The fuel efficiency must be significantly improved, and the sonic boom propagating to the ground must be dramatically reduced. Both of these objec- tives can be achieved by reducing the shockwaves formed in supersonic flight. The Busemann biplane is famous for using favorable shockwave interaction to achieve nearly shock-free supersonic flight at its design Mach number. Its performance at off-design Mach numbers, however, can be very poor. This dissertation studies the performance of supersonic biplane airfoils at design and off-design conditions. -

ExperimentalExperimental AerodynamicsAerodynamics Lecture 4: Delta wing experiments G. Dimitriadis Experimental Aerodynamics Introduction •! In this course we will demonstrate the use of several different experimental aerodynamic methodologies •! The particular application will be the aerodynamics of Delta wings at low airspeeds. •! Delta wings are of particular interest because of their lift generation mechanism. Experimental Aerodynamics Delta wing history •! Until the 1930s the vast majority of aircraft featured rectangular, trapezoidal or elliptical wings. •! Delta wings started being studied in the 1930s by Alexander Lippisch in Germany. •! Lippisch wanted to create tail-less aircraft, and Delta wings were one of the solutions he proposed. Experimental Aerodynamics Delta Lippisch DM-1 Designed as an interceptor jet but never produced. The photos show a glider prototype version. Experimental Aerodynamics High speed flight •! After the war, the potential of Delta wings for supersonic flight was recognized both in the US and the USSR. MiG-21 Convair XF-92 Experimental Aerodynamics Low speed performance •! Although Delta wings are designed for high speeds, they still have to take off and land at small airspeeds. •! It is important to determine the aerodynamic forces acting on Delta wings at low speed. •! The lift generated by such wings are low speeds can be split into two contributions: –!
