Book excerpt: A literature survey was performed to identify and review technical material applicable to the problem area of propeller propulsion system integration. The survey covered only aerodynamic interference aspects of the problem, and was restricted primarily to propeller effects on the airframe. The subject of airframe aerodynamic interference on the propeller was limited to the problem of vibration due to nonuniform inflow. The problem of airframe effects on propeller performance was not included. A total of 1121 references are given. The references are grouped into the subject areas of Aircraft Stability, Propulsive Efficiency, Aerodynamic Interference, Aerodynamic Interference-Propeller Vibration, and Miscellaneous.

This book was released on 2016-08-09 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The concepts of increasing STOL capabilities to the larger transport and cargo class aircrafts have been limited by there considerable size and gross take-off weights. One concept considered was to integrate propulsion systems, i.e. turbo-propellers and turbo-jets, to be utilized for increasing STOL capabilities. The broad class of test vehicles considered for this integration are for a high wing propeller driven aircraft with the addition of a turbo-jet mounted on the under side between two turbo-propellers. A model was constructed to investigate the integration and to determine what inlet distortion trends that would be expected. The analysis was conducted at The Ohio State University Aeronautical and Astronautical Research Laboratory facility with the use of the 3' x 5' Eiffel Type Subsonic Wind Tunnel. The model consisted of two 2-hp electric motors that drove a set of two, three or four bladed -- 13" diameter propellers. Located slightly aft and below propeller plane and centerline respectively, was an engine simulator, scaled to represent a 5,000 lbs thrust class turbo-jet. The engine simulator inlet was equipped including four pressure rakes with 3 total pressure immersions radially inward on each rake. The engines simulator cowl could be rotated 45 degrees for eight pressure rake positions, summing to a total of 24 total pressure measurements on the engine simulator inlet that would correspond to a turbo-jet fan face. The investigations simulated the interaction effects from take-off, climb and cruise conditions with variations of the simulated model geometry and was broken into two segments: In-flight Interaction effects and Take-off Interaction effects. The In-flight investigations required the model to be mounted with in the wind tunnel for simulation, ultimately determining the model size. Using the measured total pressures, the inlet distortions recorded have a measurement uncertainty of 2.4% and 2.1% for the In-flight wind tunnel investigations and Take-off static stand investigations respectively. The uncertainties are from combinations of pressure sensor instrumentation and repeatability in facility setup when the engine simulator cowl position change was required. The results gathered shows acceptable static distortion rates to transport aircraft engines (

Download or read book The Voith Schneider Propeller as a Model Ship Propulsion System written by Kurt Benz and published by Verlag für Technik und Handwerk. This book was released on with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: What even the most attentive observer of model ship events or championships might not have noticed so far is the fact that almost no model ships equipped with Voith model propellers are to be seen. This does not only apply to our nation, the actual manufacturing country of this propulsion system, but also in model building circles of other countries nothing positive is to be reported in this respect. In general, it seems to the author, the existence of this drive is hushed up in modeling circles. The reason is most likely the lack of know how. This is in no way intended to cast doubt on the technical qualities of the model builders, but rather to express the fact that there is still no useful documentation on model Voith-Schneider propellers. A circumstance which is to change with the construction description found in this book. At this point, the author would also like to dispel the widespread opinion that the Voith-Schneider propeller is a "miracle" or even a "witch's work" and can only be understood or produced by model builders with above-average technical skills. With regard to production, it must be said that it can be made by any reasonably technically skilled model builder.
