Percival Mew Gull
Le Percival Mew Gull par Jean-Louis BLENEAU Edgar Percival lui-même, reconnaissable à son éternel chapeau, se prépare à effectuer le premier vol du Mew Gull ZS-AHM (E.2H c/n E.22) The Golden City, un des concurrents de la Schlesinger Air Race. Le Major Miller abandonnera à Belgrade et l'avion fut ré immatriculé G-AEXF avant de connaître une très longue carrière. Edgar W. Percival avait dessiné son Model D Gull pour participer à la King’s Cup de 1932, épreuve qu’il termina à la 12e place sur 31 classés. Pour l’édition 1933 le moteur Cirrus Hermès de 130 ch fut remplacé par un Napier Javelin de 160 ch mais le pilote australien ne dépassa pas le cap des éliminatoires, certainement victime de problèmes de mise au point de son moteur. Le Gull fut, on le sait, produit en série et se comporta honorablement dans diverses compétitions sportives. Mais Edgar Percival était d’abord un pilote et la King’s Cup restait un objectif personnel. Il mit donc fin 1933 en chantier un monoplace de vitesse pure dont les principes de construction reprenaient ceux employés pour la réalisation du triplace. En réalité la désignation Mew Gull recouvre deux appareils assez différents pour un total de six exemplaires construits. Un monoplace pour la King’s Cup : Le 26 janvier 1934 furent réservées les lettres G-ACND pour un monoplace de course très compact (7,31 m d’envergure pour 5,56 m de long) entrainé par un moteur 6 cylindres en ligne Napier Javelin de 165 ch. -

Warranted Surveillance? Evaluating the Economic Case for Space-Based Ads-B
WARRANTED SURVEILLANCE? EVALUATING THE ECONOMIC CASE FOR SPACE-BASED ADS-B by Dorothy Robyn and Kevin Neels January 2017 The authors prepared this report as an independent, self-funded research endeavor. (The research grew out of discussions with Aireon but we ultimately chose to pursue it independently.) We want to acknowledge the many individuals who agreed to be interviewed as part of our research and who reviewed the report in draft. We specifically want to thank Aireon for its cooperation, including its willingness to share the results of the ISA analysis described in Section IV.

Government and British Civil Aerospace 1945-64.Pdf
Journal of Aeronautical History Paper No. 2018/04 Government and British Civil Aerospace 1945-64 Professor Keith Hayward Preface This paper is something of a trip down an academic memory lane. My first book, published in the early 1980s, carried a similar title, albeit with a longer time span. While it had the irreplaceable benefit of some first hand memories of the period, the official record was closed. A later history of the UK aircraft industry did refer in part to such material dating from the 1940s, but access to the ‘secret’ historical material of the 1950s and beyond was still blocked by the then “Thirty Year” rule. By the time the restrictions were relaxed to a “Twenty Year” rule or even more by the liberality offered by “Freedom of Information” legislation, I had moved on to the more pressing demands of analysing the world aerospace industry for the SBAC. 1 My years at the Royal Aeronautical Society afforded a bit more scope. Discovery of an archive on the formation of the British Aircraft Corporation, and published by the Royal Aeronautical Society’s Journal of Aeronautical History 2, stimulated a hankering to open more musty files on the 1950s. This led to a series of articles published in the Aviation Historian. However much this satisfied an initial hankering to look back to a critical period in UK aerospace, there were gaps to be filled in the narrative and the analysis. With the encouragement of the Editorial Board of the Journal of Aeronautical History, I have endeavoured to provide a more coherent overview of government policy towards the civil sector. -
Environmental Benefits of Space-Based ADS-B
Environmental Benefits of Space-based ADS-B Karen Marais, Ph.D. Associate Professor School of Aeronautics and Astronautics, Purdue University December 2016 Executive Summary. Commercial aviation worldwide contributes about 2% of global manmade CO2 emissions annually [ICAO, 2016a]. Efforts are proceeding along many fronts to reduce aviation’s environmental impact. This year, the UN’s International Civil Aviation Organization (ICAO) recommended the first-ever CO2 certification standard for commercial aircraft. The Air Transport Action Group (ATAG), an international coalition of aerospace manufacturers, airlines, airports and air navigation service providers, is committed to improving overall fuel efficiency by 1.5% annually through 2020. Advances in sustainable alternative jet fuel research and development could turn commercially viable, low-carbon fuels from fantasy to reality in the not-too-distant future. But, among all of these efforts, only operational efficiency improvements—reducing the amount of fuel or time it takes an aircraft to go from point A to point B—bring immediate CO2 reductions. Efforts to improve one area of operational efficiency—Air Traffic Management—have centered mostly on areas where aircraft are under constant radar control. Examples of operational efficiency improvements include single-engine taxi procedures, continuous/idle power descents, and optimized profile descents and approaches during which aircraft fly shorter approach patterns at lower power settings [Marais et al., 2013]. One area for significant operational and procedural improvement remains underexploited: remote and oceanic airspace. In contrast to air traffic control over land, where controllers use real time radar returns to monitor and separate aircraft, air traffic control over the Atlantic Ocean and other remote regions must be performed without radar data. -

Parameter Optimization of a Low Temperature Difference Gamma-Type Stirling Engine to Maximize Shaft Power by Calynn James Adam S
Parameter Optimization of a Low Temperature Difference Gamma-Type Stirling Engine to Maximize Shaft Power by Calynn James Adam Stumpf A thesis submitted on partial fulfillment of the requirements for the degree of Master of Science Department of Mechanical Engineering University of Alberta © Calynn James Adam Stumpf, 2019 Abstract An investigation was performed with three main objectives. Determine the configuration and operating parameter of a low temperature difference Stirling engine (LTDSE) that would result in the maximum shaft power. Calculate the mean West number for LTDSEs and compare it to the mean West number for high temperature difference Stirling engines (HTDSEs). Validate the methods used to estimate the compression ratio of a Stirling engine. Three different LTDSEs were developed: The Mark 1, Mark 2, used for initial development and the EP-1. The EP-1 used a bellows for its power piston and was the main engine investigated. A test rig was used that allowed for measurement of temperature, pressure, torque, engine speed, and crank shaft position. The LTDSEs were operated with a thermal source and sink temperature of 95 °C and 2 °C, respectfully, and were heated and cooled with two water flow loops. They used air as a working fluid and a constant buffer pressure of the atmosphere, which was equal to 92.5 kPa. The compression ratio, phase angle, position of the thermal source heat exchanger, and power piston connection to the workspace was varied on the EP-1 to determine its maximum shaft power. A compression ratio of 1.206 ± 0.017, phase angle of 90 ± 1°, and the thermal source heat exchanger residing on top with the power piston connected to the expansions space resulted in the configuration that produced the maximum local shaft power. -

Singapore Takes Flight: a Hundred Years
Aviation history was made on 16 March 1911. On this day, the first aircraft took flight in Singapore, when a Bristol Boxkite biplane piloted by Joseph Christiaens rose into the air from the old Race Course at Farrer Park. It was a flight demonstration at the first aviation meet held in Singapore. To mark the centenary of this historic occasion, the Singapore Philatelic Museum has opened a new exhibition titled Singapore Takes Flight: A Hundred Years. Running from 11 March till September 2011, SINGAPORE TAKES this exhibition celebrates the milestone event with picture postcards, postage stamps and first day covers alongside a private collection of model aircraft on loan from Mr Ralph Aeria. An award-winning philatelic collection, Malayan Airmail 1911-1942, from Mr Lim Sa Bee will also be displayed from end March to June 2011.
