Euler analysis of a swirl recovery vane design for use with an advanced single-rotation propfan

Recent work has demonstrated the propulsive efficiency improvement available from single- and counter-rotation propfans as compared with current technology high bypass ratio turbofans. The concept known as swirl recovery vanes (SRV) is examined through the use of a 3-D Euler code. At high speed cruise conditions, the SRV can improve the efficiency level of a single-rotation propfan, but a concern is to have adequate hub choke margin. The SRV was designed with 2-D methods and was predicted to have hub choking at Mach 0.8 cruise. The 3-D Euler analysis properly accounts for sweep effects and 3-D relief, and predicts that at cruise the SRV will recover roughly 5 percent of the 10 percent efficiency loss due to swirl and have a good hub choke margin

Kickin\u27 Sand and Tellin\u27 Lies

This document is the script of the two-act play, Kickin’ Sand and Tellin’ Lies, by Jackson B. Miller and Christopher Forrer. The Linfield College Theatre Program presented the world premieres of the play in November 2012 in McMinnville, Oregon and in Pacific City, Oregon. The play was created as part of the Launching through the Surf: The Dory Fleet of Pacific City project, which focuses on the historical and contemporary role of dory fishers and dories in the life of the coastal village of Pacific City, Oregon. Inspired by stories from the project, Kickin’ Sand and Tellin’ Lies is a fictional work. Inquiries concerning the professional or amateur rights to produce Kickin’ Sand and Tellin’ Lies, or any part thereof, should be addressed to Jackson B. Miller ([email protected]) or the Department of Theatre and Communication Arts, Linfield College, 900 SE Baker St., McMinnville, OR 97128 (503-883-2802).https://digitalcommons.linfield.edu/dory_kstl_play/1002/thumbnail.jp
