THE PROGRESS OF SCIENCE

THE LA UNCHING OF THE " LANGLEY "

FOR three inventions that havc transformed modern warfare, th4 aeroplane, the submarine and th4 automobile, this country is in largi measure responsible. Like other in ventions, they have had a long course of evolution contribute( through centuries by many lands but the critical advances appear t have been made here. In the casc

of the automobile, including the truck and the tractor, and of the telephone, also of prime importance in warfare, the use has been most extensive in America. The aero- plane and the submarine, at present of use chiefly in warfare, have nat- urally had their principal develop- ment among the nations at war. But what has been accomplished here with the automobile and the telephone will be accomplished with

the aeroplane and the submarine, since they have become a necessity to us.

The production -of aeroplanes on a large scale and the scientific re- search which created the aeroplane have been linked together by giving the name "Langley" to' the first Handley-Page bombing machine built in America. This huge ma- chine was launched on July 6 from the yards of the Standard Aircraft Corporation at Elizabeth, New Jersey. According to Flying, speeches were made by President Mingle, of the company, Assistant Secretary of War Crowell, Mr. John D. Ryan, director of aircraft production, and General William L. Kenly, director of military aero- nautics, Sir Henry Fowler, repre- senting the British government, for whom the machine was built, and Mr. Langley, nephew of Samuel Pierpont Langley, who said:

" My uncle, Professor Langley, was not more than fifteen or sixteen years old, while lying under a tree in the field, he gazed up and saw a hawk flying, and he said, ' If a hawk can fly, men can.' Twenty years later he took up that problem and put his whole efforts to investi- gate the action of plane surfaces, and he said, 'what were the vital facts that we must know,' and it was this first investigation of the air action upon plane surfaces that brought him to the attention of sci- entists, and they said, 'go ahead.' Since that time the world has been very kind in acknowledging his re- searches; for the application of his principles by the men of America and every other nation has now produced actual flying machines ac- cording to the calculations that he set down."

The Handley Page, with a wing spread of 100 feet and driven by twin Liberty motors of 400 horse- power each, has a range of 600 fly- ing miles with an average speed of 90 miles per hour. The aeroplane

is of the 0-400 type and was put into production in April. Without its cargo of bombs, the machine weighs 9,000 pounds and to drive it requires fuel consumption of ap- proximately sixty gallons an hour. The Liberty motors are in an armored compartment on either side of the fuselage. In addition to its bombs, the machine also mounts two light Browning machine guns, which can be fired from any desired angle.

Samuel Pierpont Langley, secre- tary of the Smithsonian Institution, died on February 27, 1906, at the beginning of the era of mechanical flight to which his researches had so largely contributed. In 1905 the Wright Brothers remained in the air for half an hour but it was not until 1908 that they fully demon- strated the practicability of sus- tained flight. Langley began his experiments when he was director of the Allegheny Observatory, and in 1887 carried on experiments with free flight models. He showed as the result of experiment and theory that one-horse power would propel and sustain in horizontal flight at the velocity of about forty miles an hour somewhat more than two hun- dred pounds. In 1901 Langley be- gan the construction of a light steam-engine as a motor. Daimler had invented the internal combus- tion engine in 1885, but it was nec- essary to await for the development of the automobile to demonstrate the remarkable combination of power and lightness in an engine which has made possible the con- temporary aeroplane. Mr. Langley was, however, able to construct an aerodrome, as he called it, which weighed about 44 pounds and which flew for half a mile on May 6, 1896. In 1898 the War Department appro- priated $50,000 for experiments with a man-carrying aerodrome. After many experiments and after overcoming many difficulties, the at- tempt was made to launch the aero-

drome, with Mr. Manley as aviator, on October 7, 1903. Owing to de- fects in the launching the trial ended disastrously, and Mr. Manley narrowly escaped drowning. The experiment was repeated on Decem- ber 8, when again the launching gear was at fault, and the aero- drome had no opportunity to demon- strate its power of flight. Owing mainly to ridicule in the newspapers and the fear of its effect on the Congress, the Army Board was un- willing to continue the work. The Langley aerodrome, however, with a new engine flew over Lake Kenka in June, 1918.

ANCIENT ARMOR ADOPTED TO MODERN WARFARE'

THE war has brought back into use many discarded weapons and practices of medieval warfare. This is shown in the adoption of steel helmets by all the warring powers; in the use of heavy breast- plates by the Germans, and lighter breastplates, for attack, by the English; in the armored waistcoats used by the Italians and in trench shields which all the armies are using. Because of this it has be- come desirable to review the entire study of ancient armor, to which for centuries some of the greatest artists and scientists gave their best efforts. To such masters of the science of armor design as Leo- nardo, Guilio Romano, Cellini, Hol- bein, Duerer, Michael Angelo, and others, are ordnance experts of to- day turning for guidance and inspi- ration. In fact, it can be stated that so completely were armored de- fenses studied in the past that to- day there is scarcely a technical idea brought forward which was not worked out in elaborate detail by the old-time armor makers.

Fortunately for the Ordnance De- partment, one of the greatest collec-
