Space Age prop power comeback eyed by NASA Lewis
NASA's Lewis Research Center tests compact eight bladed propellers in wind tunnels aiming to cut fuel use by 20 to 40 percent over turbofan engines at cruise speeds up to 590 miles per hour and altitudes above 30 000 feet. If feasible, a prop driven airliner could rival jets in efficiency and cabin comfort while city airports hope to quiet jet noise though public demand for a prop revival remains uncertain. Cape Columbia near Ellesmere Island marks the article's northern reference.
