(John Mackenzie) title: The Dominion of the Air: The Story of Aerial Navigation date: None words: 90475 flesch: 59 summary: It is time then, taking events in their due sequence, that mention should be made of the endeavours of various savants, who began about the commencement of the nineteenth century to gather fresh knowledge from the exploration of the air by balloon ascents organised with fitting equipment. When, then, to this great outlay was added the difficulty and delay of producing a sufficient supply by what was at best a clumsy process, as also the positive failure and consequent disappointment which not infrequently ensued, it is easy to understand how through many years balloon ascents, no longer a novelty, had begun to be regarded with distrust, and the profession of a balloonist was doomed to become unremunerative. keywords: account; aeronaut; air; air balloon; altitude; ascent; ballast; balloon; balloon ascent; car; case; chapter; cloud; country; course; coxwell; currents; day; degrees; descent; direction; distance; earth; experience; fact; feet; flight; flying; following; gas; glaisher; great; green; ground; half; hand; height; hour; left; machine; man; means; miles; minutes; moment; new; night; occasion; p.m.; parachute; paris; place; point; power; rope; sea; sky; spencer; success; surface; temperature; time; valve; voyage; water; way; wind; years cache: 861.txt plain text: 861.txt item: #34 of 35 id: 874 author: Vivian, Evelyn Charles title: A History of Aeronautics date: None words: 138494 flesch: 55 summary: Although, in model form, there is nothing quite so strikingly successful as the helicopter in the range of flying machines, yet the essential weight increases so disproportionately to the effective area that it is necessary to go but very little beyond model dimensions for the helicopter to become quite ineffective. It now seems likely that two forms of flying machines, a sporting type and an exploration type, will be gradually evolved within one or two generations, but the evolution will be costly and slow, and must be carried on by well-equipped and thoroughly informed scientific men; for the casual inventor, who relies upon one or two happy inspirations, will have no chance of success whatever.' Follows Professor John J. Montgomery, who, in the true American spirit, describes his own experiments so well that nobody can possibly do it better. keywords: aeroplane; air; air flight; air machine; airship; angle; balloon; biplane; bird; body; british; brothers; car; case; construction; crank; cylinder; day; days; design; development; diameter; direction; dirigible; end; engine; exhaust; experiments; fact; feet; flight; flying; flying machine; form; forward; french; gas; german; ground; high; horizontal; horse; hour; inches; lbs; left; length; lift; lilienthal; little; long; machine; man; means; miles; military; minute; motor; order; period; pilot; piston; place; planes; point; power; power engine; pressure; propeller; rear; record; resistance; revolutions; rudder; second; set; speed; square; steam; steel; stroke; success; surface; time; total; type; vertical; war; water; way; weight; wind; wings; work; years cache: 874.txt plain text: 874.txt item: #35 of 35 id: 907 author: Jackman, William J.

Leaving balloons and various forms of gas-bags out of consideration, other experimenters, notably Langley and Lilienthal, antedated him in attempting the navigation of the air on aeroplanes, or flying machines, but none of them were wholly successful, and it remained for Chanute to demonstrate the practicability of what was then called the gliding machine. keywords: aeroplane; air; area; aviators; bird; bleriot; construction; control; curtiss; end; engine; feet; flight; flying; flying machine; foot; frame; ground; horizontal; horsepower; hour; inches; machine; miles; motor; operator; pitch; planes; pounds; power; propeller; rear; rudder; speed; square; surface; time; use; vertical; weight; wind; wright machine cache: 907.txt plain text: 907.txt
