It was operated by a motor driven by a bichromate of soda battery. The motor weighed 121 lbs. The cells held liquid enough to work for 2-1/2 hours, generating 1-1/3 horse power. The screw had two arms and was over nine feet in circumference. Tissandier made some successful flights. The first dirigible balloon to return whence it started was that known as La France.
Many evenings had been devoted to discussing, not the form of its screw nor its dimensions, but whether it ought to be put behind, as the Tissandier brothers had done, or before as Captains Krebs and Renard had done. It is unnecessary to add that the partisans of the two systems had almost come to blows. The group of "Beforists" were equaled in number by the group of "Behindists."
After Tissandier, he is doubtless the veteran journalistic aëronaut of the world. Beginning in 1861, he has made in all twenty-six voyages, some of them perilously eventful, including several night-flights of hundreds of miles. Most of his experience has been gained with Mr. King, though he accompanied Donaldson on several occasions. At the request of Professor Abby of the Signal Service, Mr.
His greatest speed against a moderate breeze was only about 5 miles an hour, and the endurance of the men did not allow of even this speed being kept up for long at a time. In the year 1883 Tissandier invented a steerable balloon which was fitted with an electric motor of 1 1/2 horse-power. This motor drove a propeller, and a speed of about 8 miles an hour was attained.
Aëronauts have been free and accepted members of this order of modern knights-errant, from hot-headed, ill-fated Pilâtre de Rozier down to Gaston Tissandier, the man who still edits La Nature in the lower strata of an ocean into the treacherous upper depths of which he has risen seven miles.
It was but shortly after this, on March 26, 1870, that Charles Green passed away in the 85th year of his age. De Fonvielle's colleague, M. Gaston Tissandier, was on one occasion accidentally brought to visit the resting place of the earliest among aeronauts, whose tragic death occurred while Charles Green himself was yet a boy.
Gas also was procurable, and we had amongst us quite a number of men expert in the science of ballooning, such as it then was. There was Nadar, there was Tissandier, there were the Godard brothers, Yon, Dartois, and a good many others.
The first of these had been successfully accomplished in a flight of twenty-four hours' duration from Paris to Bordeaux. It was now April the 15th, and the lofty flight was embarked upon by M. Gaston Tissandier, accompanied by MM. Croce-Spinelli and Sivel.
A tabular comparison of the four navigable balloons which we have now described has been given as follows: Date. Name. Motor. Vel. p. Sec. 1852 M. Henri Giffard Steam engine 13.12 ft. 1872 M. Dupuy de Lome Muscular force 9.18 ft. 1883 MM. Tissandier Electric motor 9.84 ft. 1884 MM. Renard & Krebs Electric motor 18.04 ft.
Within two hours from quitting the train the airship may be ready for its flight to the interior of the technically-besieged town. 'Such may be the outline of the task a task presented imperiously to French balloonists by the events of 1870-1, and which all the devotion and science of the Tissandier brothers failed to accomplish. To-day the problem may be set with better hope of success.
