The European Bronze Age Sword……………………………………………….21
48-JLS-0069 The Virtual Armory Interactive Qualifying Project Proposal Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for graduation by _____________________________ ____________________________ Patrick Feeney Jennifer Baulier _____________________________ Ian Fite February 18th 2013 Professor Jeffrey L. Forgeng. Major Advisor Keywords: Higgins Armory, Arms and Armor, QR Code 1 Abstract This project explored the potential of QR technology to provide interactive experiences at museums. The team developed content for selected objects at the Higgins Armory Museum. QR codes installed next to these artifacts allow visitors to access a variety of minigames and fact pages using their mobile devices. Facts for the object are selected randomly from a pool, making the experience different each time the code is scanned, and the pool adapts based on artifacts visited, personalizing the experience. 2 Contents Contents........................................................................................................................... 3 Figures..............................................................................................................................6 Introduction ……………………………………………......................................................... 9 Double Edged Swords In Europe………………………………………………………...21 The European Bronze Age Sword……………………………………………….21 Ancient edged weapons prior to the Bronze Age………………………..21 Uses of European Bronze Age swords, general trends, and common innovations -

The SKYLON Spaceplane
The SKYLON Spaceplane Borg K.⇤ and Matula E.⇤ University of Colorado, Boulder, CO, 80309, USA This report outlines the major technical aspects of the SKYLON spaceplane as a final project for the ASEN 5053 class. The SKYLON spaceplane is designed as a single stage to orbit vehicle capable of lifting 15 mT to LEO from a 5.5 km runway and returning to land at the same location. It is powered by a unique engine design that combines an air- breathing and rocket mode into a single engine. This is achieved through the use of a novel lightweight heat exchanger that has been demonstrated on a reduced scale. The program has received funding from the UK government and ESA to build a full scale prototype of the engine as it’s next step. The project is technically feasible but will need to overcome some manufacturing issues and high start-up costs. This report is not intended for publication or commercial use.

Swordsmanship and Sabre in Fribourg
Acta Periodica Duellatorum, Hands-on section, articles 103 Hands-on section, articles Sweat and Blood: Swordsmanship and sabre in Fribourg Mathijs Roelofsen, PhD Student, University of Bern [email protected], and Dimitri Zufferey, Independant Researcher, GAFSchola Fribourg, [email protected] Abstract – Following a long mercenary tradition, Switzerland had to build in the 19th century its own military tradition. In Cantons that have provided many officers and soldiers in the European Foreign Service, the French military influence remained strong. This article aims to analyze the development of sabre fencing in the canton of Fribourg (and its French influence) through the manuals of a former mercenary (Joseph Bonivini), a fencing master in the federal troops (Joseph Tinguely), and an officer who became later a gymnastics teacher (Léon Galley). These fencing manuals all address the recourse to fencing as physical training and gymnastic exercise, and not just as a combat system in a warlike context. Keywords – Sabre, Fribourg, Valais, Switzerland, fencing, contre-pointe, bayonet I. INTRODUCTION In military history, the Swiss are known for having offered military service as mercenaries over a long time period. In the 19th century, this system was however progressively abandoned, while the country was creating its own national army from the local militias. The history of 19th century martial practices in Switzerland did not yet get much attention from historians and other researchers. This short essay is thus a first attempt to set some elements about fencing in Switzerland at that time, focusing on some fencing masters from one Swiss Canton (Fribourg) through biographical elements and fencing manuals. -

Air-Breathing Engine Precooler Achieves Record-Breaking Mach 5 Performance 23 October 2019
Air-breathing engine precooler achieves record-breaking Mach 5 performance 23 October 2019 The Synergetic Air-Breathing Rocket Engine (SABRE) is uniquely designed to scoop up atmospheric air during the initial part of its ascent to space at up to five times the speed of sound. At about 25 km it would then switch to pure rocket mode for its final climb to orbit. In future SABRE could serve as the basis of a reusable launch vehicle that operates like an aircraft. Because the initial flight to Mach 5 uses the atmospheric air as one propellant it would carry much less heavy liquid oxygen on board. Such a system could deliver the same payload to orbit with a vehicle half the mass of current launchers, potentially offering a large reduction in cost and a higher launch rate. Reaction Engines' specially constructed facility at the Colorado Air and Space Port in the US, used for testing the innovative precooler of its air-breathing SABRE engine. Credit: Reaction Engines Ltd UK company Reaction Engines has tested its innovative precooler at airflow temperature conditions equivalent to Mach 5, or five times the speed of sound.

IAC-15-D2.1.8 PROGRESS on SKYLON and SABRE Philippa
IAC-15-D2.1.8 PROGRESS ON SKYLON AND SABRE Philippa Davies Reaction Engines Limited, Building F5, Culham Science Centre, Abingdon, Oxfordshire, OX14 3DB, United Kingdom [email protected] Mark Hempsell1, Richard Varvill2 The Synergetic Air-Breathing Rocket Engine (SABRE) engine is comprised of state-of-the-art jet engine and rocket technology combined in a novel cycle with light-weight heat exchanger technology. Reaction Engines Ltd is gaining momentum programmatically and technically towards the first ground based demonstration of the SABRE air- breathing cycle. The SABRE engine development programme has transitioned from key technology demonstration into the design and development phase of the SABRE engine. The focus of the activities are now towards the ground- based air-breathing cycle demonstration and the engine test programme. The accomplishments over the last two years include completion of the Preliminary Requirements Review (PRR) and successful test firing of the novel rocket combustion chamber and nozzle for use in both the engine’s air breathing and rocket modes. The SABRE Engine is designed to enable the realisation of the SKYLON spaceplane. SKYLON is a reusable singe stage to orbit spaceplane that can take off from a runway to reach a 300 km altitude low earth orbit with a payload of 15 tonnes and then return to Earth for a runway landing. This paper summarises the recent technical and programmatic accomplishments, as well as the programme’s future activities to progress the design and development of both SKYLON and the SABRE engine Keywords: SKYLON, SABRE, Heat Exchangers 1. INTRODUCTION with the SKYLON spaceplane to ensure the joint advancement of the propulsion system and vehicle, For 30 years there has been activity in the United however the company’s main focus is on the Kingdom to realise the vision of a single stage to orbit development of SABRE. -
