Definition of heavier-than-air in English:



  • (of an aircraft) weighing more than the air it displaces.

    ‘the history of the development of heavier-than-air flying apparatus’
    • ‘It has been thoroughly researched in recent times that Richard Pearse was the first human being to take to the air in a heavier-than-air flying machine, and I think that is an absolutely wonderful thing.’
    • ‘Lord Kelvin, who is President of the prestigious Royal Society once said that heavier-than-air flying machines were impossible, and the Chairman of the major computer company, DEC, said that no-one would want a computer in their home.’
    • ‘Sometime before the Wright brothers' momentous flights of December 17, 1903, Quick began construction of a heavier-than-air flying machine of unknown configuration.’
    • ‘The airplane was aloft for only 120 feet, but the flight was epoch-making: the first time a powered, heavier-than-air flying machine got off the ground to make a successful, controlled flight.’
    • ‘Mistakes of approximation underlie many of the objections once aimed at new fangled ideas like heavier-than-air flying machines and practically every other aspect of modern life that we now take for granted.’
    • ‘They are also reminiscent of the 19th century scientists who claimed that heavier-than-air flying machines were impossible.’
    • ‘The Wright brothers showed that heavier-than-air flight was possible, but that did not entitle them to a monopoly of heavier-than-air flying machines.’
    • ‘Americans were the first to take weapons into the air in heavier-than-air flying machines.’
    • ‘Speed would require the development of heavier-than-air flying machines.’
    • ‘In 1886, he designed a steam-powered aircraft, and in 1896 became the first to build heavier-than-air machines capable of sustained flight.’
    • ‘On December 17, 1903, at Kitty Hawk, North Carolina, the Wright Brothers' Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard.’
    • ‘His son, my great-grandfather Bernard von Hoffmann, gave up the ballooning and started a heavier-than-air flying school at Lambert Field, where St. Louis International Airport is now located.’
    • ‘The familiar phrase ‘a picture is worth a thousand words’ rings quite true as spectacular engravings and prints bring to life fascinating events in the history of ballooning and heavier-than-air flight.’
    • ‘Not large enough to carry a man, the #5 and later the #6 did prove that mechanical heavier-than-air flight was possible.’
    • ‘For the most part, this technology culture appeared at the same time as the air service itself, due to the nature of heavier-than-air flight.’
    • ‘Actually, Augustus Moore Herring was quite a pioneer during the very earliest days of heavier-than-air flight.’
    • ‘The Pacific and North Atlantic had never been fully crossed by heavier-than-air craft.’
    • ‘For students of aviation and aeronautical engineering, the aeroplane turns out to be very useful when it comes to understanding the various principles of heavier-than-air flight, aerodynamics, and aircraft design.’
    • ‘They emerged from obscurity and made history with, as historians of aviation carefully phrase it, the first power-driven heavier-than-air machine in which humans made free, controlled and sustained flight.’
    • ‘The Wrights were not the first to pilot a heavier-than-air craft.’
