But what if the technology could be used to help the environment or save lives? This month, the UAE is again promoting the humanitarian use of drones with a $1 million competition that features the best designs from around the world.

  • The Historic “Aerodrome A”
    Politically Incorrect The Flights and Fights Involving the Langley Aerodrome By Nick Engler As morning dawned on 28 May 1914, the “Aerodrome A” perched like a giant dragonfly on the edge of Lake Keuka, surrounded by journalists, photographers, even a videographer. Members of the scientific elite and Washington DC power structure were also there, among them Charles Doolittle Walcott, the Secretary of the Smithsonian Institution, and Albert Zahm, the director of the recently reopened Langley Aerodynamical Laboratory. They carefully spun the event for the media, explaining why they were attempting to fly the infamous Langley Aerodrome eleven years after two highly-publicized, unsuccessful, and nearly- catastrophic launch attempts. A cool breeze blew down the lake, gently rocking the four tandem wings that sprouted from the Aerodrome’s central framework. It was time to go. As the sun crept higher in the sky the winds would kick up. With a pronounced 12-degree dihedral between the pairs of 22-foot wings, even a modest crosswind could flip the old aircraft if it got under a wing. Workmen from the Curtiss Aeroplane and Motor Company of Hammondsport, New York lined up along the pontoons and outriggers recently added to the airframe. They lifted the half-ton aircraft a foot or so above the ramp, duck-walked it into the water and turned it into the wind. 1 Glenn Curtiss waded out, stepped onto the braces between the forward pontoons and climbed into the nacelle that hung beneath the framework. He settled into the cockpit and tested the familiar Curtiss controls – wheel, post and shoulder yoke borrowed from one of his early pushers.1 This system had replaced the dual trim wheels that had steered the original Aerodrome.

While aspects of the collection have been previously researched, including the materials amassed during Commodore Matthew Perry’s expedition to Japan (which was the first set of ethnological objects accessioned by the Smithsonian), [1] the masks presented for the first time here demonstrate that new discoveries await even within well-known legacy collections. This group of seven highly evocative masks was collected by famed inventor Alexander Graham Bell during his only journey to Japan, undertaken in 1898. In order to situate the collection historically and artistically, I outline Bell’s ties to Japan and to the Smithsonian before considering the nature and significance of the objects themselves.

Source: Volvo Aero Corporation] Printed at Chalmers Reproservice Göteborg, Sweden On the Design of Energy Efficient Aero Engines Some Recent Innovations By Richard Avellán Division of Fluid Dynamics Department of Applied Mechanics Chalmers University of Technology SE-412 96 Göteborg Abstract n the light of the energy crisis of the 1970s, the old aerospace paradigm of flying higher and I faster shifted towards the development of more energy efficient air transport solutions. Today, the aeronautical research and development community is more prone to search for innovative solutions, in particular since the improvement rate of change is decelerating somewhat in terms of energy efficiency, which still is far from any physical limits of aero engine and aircraft design. The Advisory Council for Aeronautics Research in Europe has defined a vision for the year of 2020 for aeronautical research in Europe which states a 50% reduction in CO2, 80% reduction in NOx and a 50% reduction in noise.

Chapter 2 Preparing the Ground for Delving into the Stars 2.1 The Long Road to Deciphering the Composition of the Stars All our knowledge about the composition of cosmic objects is obtained via spec- troscopy. Two key disciplines are required to extract this information from obser- vations: the theory of radiative transfer through stellar material and the theory of atomic structure. Spectroscopy is as old as modern science. It began with Johannes Kepler (1571–1630m)1 and later Isaac Newton (1643–1727m), who knew about the effect of the prism on sunlight.2 When they cast the outgoing light of the prism on a screen, they discovered all the colors of the rainbow. Naturally, Newton used a circular aperture, and consequently his spectrum was not pure. Despite this early start, progress was slow at the beginning, and even after major breakthroughs, about 400 years were needed before reliable information about stellar composition could be obtained.
