Wrights sold licenses from that year. Dumont was the first to purchase in 1908. He distributed licenses to other French manufactors.phylo_roadking wrote:P.S....
...can I ask - where did this date come from?that the others were still having trouble getting off the ground for the next 4-5 years. It is not until after 1908 the other are able to emulate the Wrights ability in the air.
Dumont managed a 21 second flight tin 1906, 220 meters straight line. Subsequent models and flights managed similar straight line distances & times. Bleriots 1907 flights managed 500 meters with one flight including a 180 degree turn at the end of the year. In 1908 he scrapped that model and built a entirely new design. Voisin built the aircraft Bleriot tested 1906 & 1906. In January 1908 his newest deisgn managed a one kilometer closed course. Roe managed a few hundred meters straight line in 1907 with a rudderless machine in 1907. In 1908 he got a couple more flightsphylo_roadking wrote:Alberto Santos-Dumont in 1906, Louis Bleriot in 1907, Gabriel Voisin's biplane in 1907, AV Roe in 1907....
By 1905 the Wright flyers were routinely flying multi kilometer flights with repeated turns. The longest that year recorded at 39 kilometers in 39 minutes.
What I had pointed out to me is the original patent did not cover 'wing warping' control' only, but refered to control at the outer edges of the wings in general. That is the Wrights understood there were other, perhaps better mechanical methods for achieving the control they had achieved in their first powered flyer. I dont know if they had anything specific on paper or in models for their wind tunnel.
Yeah they did. Their law suite vs Glen Curtis revolved around his use of hinged alerons. The patent court unpheld the Wrights claim. In 1917 the US government effectively took control of Wrights patent and distributed license to the other manufactors in order to unstick war production. The Wright patent was wrtiten to cover the most effective methods of controling Yaw & Roll. Dumont judged it better to pay for a license rather than thry to make a case in the courtsphylo_roadking wrote:Carl - I don't think they did. What they DID discover was the intimate connection between controlling roll and yaw simultaneously I.E. they did a lot of work on "control" and their way of how to achieve it...but not via ailerons. They did use hinged elevators - on the Flyer's canard - and the rudders were hinged...but wingwarping was always their path to controlling roll and yaw.
