To the surprise of even two such veteran flyers as John Ross and Tom Meeks, the airplane had gone less than fifty yards when she began to rise as gracefully as a swallow in response to her up-turned ailerons and elevators. In less than ten seconds she was well up over the fair-grounds, and the roofs of all the buildings in the neighborhood were seen below them.
"High enough so the hum won't be noticed on the ground? Or do you want to fly lower?" "Top of your head means high, and on the neck, low," Johnny promptly finished his code. Having thus made a code keyboard of Bland's person, he settled himself with his guns beside him. Bland eased on the power, glancing unconsciously to the right and left ailerons, as he always did when he started.
Really got it?" cried the girl, starting up. "Oh " "Feel this!" he answered. "Grab hold and pull!" She obeyed, trembling with eagerness. "It's caught through one of the ailerons, or some yielding part, I think," he said. "Here, help me hold it tight, now; we mustn't let the hook slip out again!" To the patriarch he added: "Tell 'em to back up, there easy easy!"
He pulled the control wires and made the ailerons swing up and down, which always raised a laugh among the crowds.
On its side an airplane will cushion its own bank of proper degree by the use of ailerons. These ailerons are sections of the wing-tips which may be moved either up or down. They are counterbalanced so that movement of the left down gives you the right aileron up.
The fresh air of the morning came with a stinging rush to my face. Below I could see the earth sweeping past as if it were a moving-picture film. Above the continuous roar of the engine and propeller Norton indicated to Kennedy the automatic balancing of the gyroscope as it bent the ailerons. "Could you fly in this machine without the gyroscope at all?" yelled Kennedy.
In making these first turns a pupil finds that, apart from his action with the rudder-bar, it is necessary to employ the ailerons slightly, so as to prevent the biplane from tilting sideways.
Now John threw in the clutch; the revolving propeller shaft grabbed the crankshaft of the engine, and once more it began its rhythmic purr. Just a little upthrust of the tail-elevators and ailerons brought them again into the horizontal in a huge swoop. Nothing could have been prettier.
THE FARMAN AILERONS. Farman's disposition is somewhat different, as shown in sketch 3. The wings are hinged to the upper planes at their rear edges, and near the extremities of the planes. Operating wires lead to a lever within reach of the aviator, and, by this means, the wings are held at any desired angle, or changed at will.
Suddenly, as a sharper puff than usual came, the Buzzard gave a lurch that Malvoise in vain tried to counteract by using his ailerons. These balancing devices are almost automatic in their control, and usually can be depended on to control an airship to keep an even keel, but this time not even Malvoise's skill could save the Buzzard. Down she sped, straight as a plummet, for fully fifty feet.
