    Default D.Y.K? -- Space Flight

    As you know, the Wright brothers, Orville and Wilbur
    made their historic first flight of a soon-to-be-called
    "airplane" in 1903. We might also mention that a man
    called George Cayley and another, Otto Lilienthal, were
    instrumental in this because of their work with gliders
    during the mid-to-late 19th century.

    Also, honorable mention goes to Samuel Langley for
    almost but not quite beating the Wright Brothers to
    world fame and renown. One reason the Wrights beat
    him is that they invented "ailerons," movable wingtips
    that enabled the pilot to control the plane. They also
    designed new engines of unprecedented lightness for
    the power they could deliver.

    Some pretty cool bike repairmen, eh?

    Anyway, did you know?

    That very same year, 1903, oddly enough was the year
    that space flight began to receive true scientific attention.

    In 1903, the Russian physicist Konstantin Tsiolkovsky
    began a series of articles for an aviation magazine in
    which he went into the theory of rocketry quite thoroughly.
    He wrote of space suits, satellites, and the colonization
    of the solar system. He was the first to suggest the
    possibility of a space station.

    One hundred years ago... TODAY.

    happy days and...
    starry starry nights!

    From their bicycle experience, the Wrights had a major head start,
    beceuse they knew that banking (or roll control) was the key to turning
    in flight. To achieve it, they invented wing warping, not ailerons.
    To skirt the Wrights' wing-warping patent, Glenn Curtiss
    invented ailerons, or movable 'middle wings' to achieve roll control.
    This became the root of bitterly contentious patent-infringement
    lawsuits by the Wrights against Curtiss. Some believe it exascerbated
    Wilbur's ill health and premature death in 1912.. all over the 'aileron'


    Indeed. In 1909 Wilbur said of Cayley, "About 100 years ago an
    Englishman, Sir George Cayley, carried the science of flying to a point
    it had never reached before and which it scarcely reached again during
    the last century."
    It can rightly be said that Cayley *invented* the
    airplane, though not a man-carrying, powered one capable of coordinated
    turns. By correct placement of the center of gravity and use of a
    negative-incidence tailplane, Cayley's glider designs demonstrated
    auto-stability in straight-forward flight. Ironically, the Wrights did
    not build such auto-stability into their gliders or the 1903 Flyer,
    resulting in severe instability, particularly in the pitch axis. All the
    more kudos to their mastery of actually controlling the maverik
    machine.. *on the road to space*. oc

    Ah, to quote Sinatra.. "It was a Very Good Year".

    1903 also saw the founding of Harley-Davidson. Recently, students of
    Utah State University built a modern, all-composite replica of the 1905
    Wright Flyer, powered by what else- a rasty Harley Davidson engine
    driving the propellers thru the trademark chain-and-sprocket
    transmission... *on the road to space*. oc

    Have you followed the attempts to repeat the flight? IIRC, because of the
    inherent instability of the design, there were some definite concerns about
    the ability to control it. So the thing was simulated in a trainer so the
    pilot could get experience. The more I learn about it, the more impressed I
    am with what the Wrights accomplished.

    I don't think there's any irony involved. AFAIK, The Wright brothers
    deliberately designed their machine to be unstable, believing that was
    the only way to make it responsive to the controls.

    Not really. The Wright brothers did invent the aileron, but not until
    after the success of their first airplane. The first Wright flyer used
    wing warping instead. It did, however, have a rudder and an elevator.

    Yes, very closely. The replica 1903 machine was flown previous to the 17
    Dec. attempt, to prove it would fly. The 'Big Day' came with lousy
    weather, rain, and apparently insufficient headwind. A valiant attempt
    was made to lift off, but it didn't quite make it. oc

    You are absolutely correct. "Irony" was the wrong word to use.
    Deliberate, designed-in instability in all 3 axes was the surest way to
    learn to 'tame the beast', particularly in making coordinated turns.
    Other inventors had sought stability first, and hence precluded anything
    more than straight-line 'hops'. oc

    Not exactly. The Wrights detested ailerons. Why? Because Glenn Curtiss
    used ailerons as the means of circumventing their exclusive patent on
    3-axis control, resulting in the famous lawsuits.

    All the Wright machines until 1916 used wing warping exclusively in lieu
    of ailerons, so great was the Wrights' aversion to them. Only in 1916
    was a Model 'B' modified to use ailerons, and the Model 'L' of 1916, the
    very last of the lineage, used ailerons. oc

    Yes, I stand corrected. Apparently a guy named Christmas also got a patent
    on ailerons.

    Someone mentioned Langley earlier. Did he ever actually make a successful
    man-sized airplane? I understand that he died in 1906.
