Download or read book Advanced High-speed Fuel Pumps for Small Gas-turbine Engines written by Harry T. Johnson and published by . This book was released on 1969 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of the program was to develop the technology necessary for vane-pump operation at turbine rotational speeds. Major hardware emphasis was devoted to the evaluation of a high-speed fuel pump based upon this technology. A single-lobe vane pump with a centrifugal charging stage was designed and successfully operated at 40,000 rpm pumping JP-4 turbine fuel. The vane pump relies upon the use of a hydrodynamically lubricated pivoting vane tip to support vane assembly radial loading. The hydrodynamic film allows a significant increase in tip surface speed without sacrificing the required endurance life. A 200-hour endurance run at speeds from 24,000 to 40,000 rpm was successfully completed with no noticeable performance degradation. Successful contamination experiments were performed after completion of 175 hours of the endurance schedule. The contamination experiments were not extensive, but they verified that the design concepts were not unduly sensitive to contaminated fuel. Continued development will be required to establish life capability at the design pressure of 650 psig, but short-term capability was established at outlet pressures up to 600 psig. No major limitations with the basic pump design were found. The 50,000-rpm goal appears to be feasible, but further evaluation at speeds above 40,000 rpm was terminated due to bearing problems in the laboratory speed-increaser system. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this program was to develop both the technology and the experimental hardware to experimentally demonstrate that a main-engine fuel pump could be operated at turbine-engine shaft speeds. A single-lobe vane pump has been designed and successfully operated at speeds up to 49,500 rpm and outlet pressures up to 900 psig while pumping JP-4 turbine fuel. The promosing capabilities demonstrated by this pump were the result of the successful application of hydrodynamic lubrication techniques to the vane design. The pivoting vane tip concept incorporated permits tip surface speeds up to 180 fps to be achieved without producing high mechanical power losses or sacrificing the pump endurance capabilities. The present experimental fuel pump represents a significant step toward the development of flight hardware capable of operating at engine shaft speed. It meets the basic performance requirements of a main-engine fuel pump typically required on small, highspeed gas-turbine engines. In addition, it appears that a variable-displacement capability could be developed directly from the present hardware without altering the established high-speed capabilities. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Aircraft Propulsion and Gas Turbine Engines, Second Edition builds upon the success of the book’s first edition, with the addition of three major topic areas: Piston Engines with integrated propeller coverage; Pump Technologies; and Rocket Propulsion. The rocket propulsion section extends the text’s coverage so that both Aerospace and Aeronautical topics can be studied and compared. Numerous updates have been made to reflect the latest advances in turbine engines, fuels, and combustion. The text is now divided into three parts, the first two devoted to air breathing engines, and the third covering non-air breathing or rocket engines.

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.
