    The current stage in aerospace at the end of 2020

    Get PDF
    The paper briefly presents some models of aircraft considered avant-garde in 2020, and it is part of the reviews on news in aviation and aerospace. It briefly presents some basic features, news, and more important data for each new model on display, so that the reader can get an image of that model but also an overall one, to compare different models from a particular manufacturer with each other, as well as with those belonging to another manufacturer. Aircraft manufacturers are constantly concerned with modifying their aircraft and building other new models that meet customer requirements as much as possible, but at the same time lead to reductions in total fuel consumption used in flight, to reduce pollution due to flights and the negative effects on planetary ecosystems, as well as the increase in the quality and safety of air travel

    Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 83-88).Birds have the impressive ability to gracefully 'swim' through the air while executing aerobatic maneuvers that routinely defy modern aeronautical and control engineering, consistently reminding us that the skies are truly their playground. These animals are masters at inducing and exploiting post-stall aerodynamics to quickly execute maneuvers with unprecedented precision, with nowhere near the sustained propulsive power found in modern state-of-the-art aircraft. This amazing ability to manipulate the air is commonly attributed to the intricate morphology of the wings, tail, feathers and overall sensory motor system of the animal. In this thesis we demonstrate, on real hardware, that using only an approximate model of the post-stall aerodynamics in combination with principled and novel tools in optimal control, even a simple fixed-wing foam glider (no propeller) made out of rigid flat plates, with a single actuator at the tail, is capable of executing a highly dynamic bird-like perching maneuver to land on a power-line by exploiting pressure drag on its stalled wings and tail. We present a feedback controller capable of stabilizing the maneuver over a wide range of flight speeds and quantify its robustness to wind-gust disturbances. In order to better characterize the aerodynamics during perching, we performed smoke-visualization in a low-speed free flight wind-tunnel, where we were able to capture real images of the dominant vortex wake dynamics. We describe the application of these results to the synthesis of higher fidelity aerodynamic models. We also demonstrate our initial perching experiments with flapping wings, using a flapping-wing version of our glider as well as our fully computerized two-meter wingspan robotic bird, Phoenix.by Rick E.
