Such application is not quite correct, since ``plane'' indicates a flat surface, and the lifting surfaces are always cambered. Propeller--See ``Air-Screw.''
Propeller, Tractor--An air-screw mounted in front of the main lifting surface. Propeller, Pusher--An air-screw mounted behind the main lifting surface. Pusher--An aeroplane of which the propeller is mounted behind the main lifting surface. Pylon--Any V-shaped construction from the point of which wires are taken. Power--Rate of working. Power, Horse--One horse-power represents a force sufficient to raise 33,000 lbs. 1 foot in a minute.英文原著 · 《The Aeroplane Speaks》
"The wing, both when at rest and when in motion," Pettigrew declared, "may not inaptly be compared to the blade of an ordinary screw propeller as employed in navigation. Thus the general outline of the wing corresponds closely with the outline of the propeller, and the track described by the wing in space IS TWISTED UPON ITSELF propeller fashion." Numerous attempts to apply the newly discovered principles to artificial birds failed, yet came so close to success that they fed instead of killing the hope that a solution of the problem would one day ere long be reached.英文原著 · 《The Age of Invention》

For example, let us find the pitch of a propeller, given the following conditions: Flying speed .............. 70 miles per hour. Propeller revolutions ..... 1,200 per minute. Slip ...................... 15 per cent. First find the distance in feet the aeroplane will travel forward in one minute. That is--
369,600 feet (70 miles) ------------------------ = 6,160 feet per minute.英文原著 · 《The Aeroplane Speaks》
Then came improvements in making nails, in making bedsteads, in the manufacture of boats, and for propelling boats by cattle. On August 26, 1791, James Rumsey, John Stevens, and John Fitch (all three will appear again in this narrative) took out patents on means of propelling boats. On the same day Nathan Read received one on a process for distilling alcohol.英文原著 · 《The Age of Invention》
