Book excerpt: The objective of the program was to determine a wave rotor demonstrator engine concept using the Allison 250 series engine. The results of the NASA LERC wave rotor effort were used as a basis for the wave rotor design. A wave rotor topped gas turbine engine was identified which incorporates five basic requirements of a successful demonstrator engine. Predicted performance maps of the wave rotor cycle were used along with maps of existing gas turbine hardware in a design point study. The effects of wave rotor topping on the engine cycle and the subsequent need to rematch compressor and turbine sections in the topped engine were addressed. Comparison of performance of the resulting engine is made on the basis of wave rotor topped engine versus an appropriate baseline engine using common shaft compressor hardware. The topped engine design clearly demonstrates an impressive improvement in shaft horsepower (+11.4%) and SFC (-22%). Off design part power engine performance for the wave rotor topped engine was similarly improved including that at engine idle conditions. Operation of the engine at off design was closely examined with wave rotor operation at less than design burner outlet temperatures and rotor speeds. Challenges identified in the development of a demonstrator engine are discussed. A preliminary design was made of the demonstrator engine including wave rotor to engine transition ducts. Program cost and schedule for a wave rotor demonstrator engine fabrication and test program were developed. Snyder, Philip H. Glenn Research Center...

Book excerpt: The U.S. Army Research Laboratory, NASA Glenn Research Center, and Rolls-Royce Allison are working collaboratively to demonstrate the benefits and viability of a wave-rotor-topped gas turbine engine. The self-cooled wave rotor is predicted to increase the engine overall pressure ratio and peak temperature by 300% and 25 to 30%, respectively, providing substantial improvements in engine efficiency and specific power. Such performance improvements would significantly reduce engine emissions and the fuel logistics trails of armed forces. Progress towards a planned demonstration of a wave-rotor-topped Rolls-Royce Allison model 250 engine has included completion of the preliminary design and layout of the engine, the aerodynamic design of the wave rotor component and prediction of its aerodynamic performance characteristics in on- and off-design operation and during transients, and the aerodynamic design of transition ducts between the wave rotor and the high pressure turbine. The topping cycle increases the burner entry temperature and poses a design challenge to be met in the development of the demonstrator engine.

This book was released on 2009-12-03 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the latest in a series of biennial assessments of the scientific and technical quality of the Army Research Laboratory (ARL). The current report summarizes findings for the 2007-2008 period, during which 95 volunteer experts in fields of science and engineering participated in the following activities: visiting ARL annually, receiving formal presentations of technical work, examining facilities, engaging in technical discussions with ARL staff, and reviewing ARL technical materials. The overall quality of ARL's technical staff and their work continues to be impressive, as well as the relevance of their work to Army needs. ARL continues to exhibit a clear, passionate concern for the end user of its technology-the soldier in the field. While two directorates have large program-support missions, there is considerable customer-support work across the directorates, which universally demonstrate mindfulness of the importance of transitioning technology to support immediate and near-term Army needs. ARL staff also continue to expand their involvement with the wider scientific and engineering community. This involvement includes monitoring relevant developments elsewhere, engaging in significant collaborative work (including the Collaborative Technology Alliances), and sharing work through peer reviews. In general, ARL is working very well within an appropriate research and development niche and has been demonstrating significant accomplishments.
