The use of a rotating propeller fan has been shown to help terrestrial autonomous robots to locate chemical sources by actively drawing air to their chemical sensor and scanning different directions for the presence of chemicals (Nakamoto et al., 1999; Ishida et al., 2001).
* Three ranges of tower efficiencies: "low" was the least efficient available for the cross-flow propeller fan tower series analyzed with efficiencies ranging from 45 to 60 gpm/hp (3.8 to 5.1 L/sxkW); "medium" with efficiencies ranging from 65 to 75 gpm/hp (5.5 to 6.4 L/sxkW); and "high" with efficiencies ranging from 80 to 100 gpm/hp (6.8 to 8.5 L/sxkW).
