Among the little group of French experimenters in these first years of practical flight, Santos-Dumont takes high rank. He built his 'No. 14 bis' aeroplane in biplane form, with two superposed main plane surfaces, and fitted it with an eight-cylinder Antoinette motor driving a two-bladed aluminium propeller, of which the blades were 6 feet only from tip to tip.
One of the earliest of the British-built Vee type engines was an eight-cylinder 50 horse-power by the Wolseley Company, constructed in 1908 with a cylinder bore of 3.75 inches and stroke of 5 inches, running at a normal speed of 1,350 revolutions per minute.
He ought to use a heavier tire if he expects to get any speed out of it. It ought to go at a pretty good clip if the chap knows how to drive. There is everything in the driving. I have taken my eight-cylinder at one hundred and ten miles easily a good many times, but my dad and the chauffeurs never get over eighty-five out of it." Frank felt his head swim. Here was talk that was talk!
Another notable example of French construction was the Panhard and Levassor 100 horse-power eight-cylinder Vee engine, developing its rated power at 1,500 revolutions per minute, and having the for that time low weight of 4.4 lbs. per horse-power.
He gesticulated with one broad forefinger. "Listen, m' girl. I'm what they call an old-timer. They want these high-power, eight-cylinder kids on the road these days, and it's all we can do to keep up. But I've got something they haven't got yet. I never read anybody on the Psychology of Business, but I know human nature all the way from Elm Street, Winnebago, to Fifth Avenue, New York."
"I never cared much for toys myself but some chaps like 'em. I have an eight-cylinder machine and a six-cylinder runabout, and that's enough to keep me going for the present. I want a racing car built for me pretty soon." "You don't live here, do you?" asked Frank, sure he would have heard somehow of this remarkable youth who talked so glibly of owning a string of cars.
The signs had all been made fight, the ice cream had been made cold, the sausages hot, and the ground glass had been put where it belonged. No longer did "our taffy stick like glue." Indeed, there was no taffy of any kind on hand, notwithstanding these blatant announcements. Along came the automobile, an eight-cylinder Super Junkster. And, yes, it was followed by another, and still another.
The seven-cylinder 50 horse-power Gnome rotary engine was fitted to the Farman machine the Voisins had fitted an eight-cylinder Antoinette, giving 50 horse-power at 1,100 revolutions per minute, with direct drive to the propeller. Farman reduced the weight of the machine from the 1,450 lbs. of the Voisins to some 1,010 lbs. or thereabouts, and the supporting area to 450 square feet.
It is equipped with a new type of Renault-Mercedes eight-cylinder motor, giving 240 horsepower at the highest crank shaft speed.
The eight-cylinder Mercedes-Daimler engine, used for airship propulsion during the War, developed 240 brake horse-power at 1,100 revolutions per minute; the cylinder dimensions were 6.88 diameter by 6.5 stroke one of the instances in which the short stroke in relation to bore was very noticeable.
