AVIATION . BY JOSEPH S. EDGERTON. AN has done a pretty good job of conquering the air, so far as he has gone and in the comparatively short space of time since the Wrights took their first flights along the wind-swept sand dunes at Kitty Hawk, N. C. The airplane of today is a far| ‘ery from the machine in which | Wilbur and Orville Wright flrst.} took flight. That machine is looked upon today as the crudest sort of flying apparatus, and few there are of the present. day flyers who would risk their necks in such a contraption, or in some of its successors, for that matter. But man, admittedly, has a long way to go, and a lot to learn about this flying business. And it is significant to note that, apart from the power plant re- search in connection with the resent-day advancement in avia- jon, man learns most from his feathered friends who have been flying since the dawn of time, when he studies flight. Divergent Paths. Flight, as the birds have de- veloped it, and fiight, as it hag been developed by man, have taken widely divergent paths to the same end. That those paths will some day converge again, but at that time in the air, not on the ground, few now connected with aviation_doubt. Hans Hocke, a Czechoslovakian inventor who has spent most of his time in Germany since the war studying the flight of birds, arrived in the Capital last week with a plane to which just an- other principle of bird-like flight had been applied, and his plane was an object of interest to a great many who are studying and furthering t&e ldvu;cement of viation in this country. o Hocke has spent the past 15 ear studying the flight of soar- zng birds for application of bird- like flight to aviation, and his study has not been without defi- 1ts. ek in which Hocke and | The plane h Haynes of New his pilgt "R lr{onyin New York, ew here f )\:‘u;k, 1& ailerons, the movable balance planes on either wing— ‘heretofore indispensable to the fiyer—securely locked and immov- able. For the balance these ai- lerons provide in maneuvering the ship, Hocke provided curious- ly up-tilted wing tips, which ob- e use of ailerons on the ;‘llg'fii ‘&l(‘:wn. The evolution of those wing tips is an interesting story of the study of birdlike flight. i Hampered By Mobility. i Hocke, as have been many oth- ers who sought to study birds in actual flight, was hampered by much too much mobility on the part of the birds he sought to study. He was in one element and the birds in another, both in their natural element, but the trouble was that the birds were in the air, sometimes very high up, and he was on the &m\md. To keep the birds in their natu- ral element and still have an og- portunity to thoroughly study their actions while going through thsil.lr, glqvxl:ke rigged up an enjous device. % Capturing soaring birds, gulls, hawks, vultures, doves and the like, he made small harnessgs, which would not hamper theéir wing action and attached them by strings to a miniature circular swing, the like of which is seen in almost any amusement park—inp these days generally with a plane- like car and a whining propeller. Round and round he sent the l'hdlr. the birds at first flapping madly to escape their harness and get off into the wide, free air. But after a while the birds ceased their efforts to escape and, setting their wings for soaring, glided around and -around the swing. His birds trained to the work, it was an easy matter for Hocke to study the conformation of the birds’ wings with the aid of a slow-motion camera. Hocke found that the birds maintained their balance with their tails and with big, finger- like feathers which they undulat- ed gently, at the tips of their wings. The tail-balance ?rlnclple al- ready had been applied to flying. He found that the wing-tip bal- ance princi]ple had not been ap- plied entirely to flight by man, so it was upon these finger-like feathers he concentrated his study. From the pictures he obtained of the birds about his circular swing he made hundreds of meas- urements, hundreds of calcula- tions on the angles at which the birds set their wing-tip feathers under varying conditions. He found that in all cases an up-tipping of these feathers by the soaring birds maintained them in an even keel and kept them on the proper course—of course with the aid of the tail feathers. There was no action of the feathers at the rear of the wings, near the tip, correspond- ing to the ailerons applied by man to his plane for maintenance of balance in flight. Problem Yet Remained. He found that there was a con- tinual undulating motion of the wing-tip feathers, even when the wings were held rigidly still. His principal problem was ap- plying the wing-tip balance to the fixed wings of a plane. He found that the up-tilt at the wing-tip must be a stationary thing, that the undulation in bird flight was impracticable for application to airplane flight as it is known to- day. The undulating motion pre- sented too big a problem of oper- ation by the pilot. But from his study of the angles at which the birds tilted these finger-like feathers at the wing tips he gained some valuable in- formation. He applied the up- tilt principle to model planes, and after a few adjustments from his first calculations, got good results. Test fiyers in Germany agreed to take up a full sized machine fitted with the up-tilted wings and immediately reported them successful. They took the precaution, how- ever, of seeing to it that their planes’ wings had ailerons on them just as an emergency measure. Hocke points out that it is not in the interest of doing away with ailerons that he has developed the wing-tip up-tilt as exempli- fled by the plane on exhibition here. The aileron, he finds, has made itself an indispensable place in aviation of today, and probably has saved as many lives in avia- tion as any one development of flight. Up-tilted Wing Differs. He finds, however, that the up- tilted wing tip does a great many things the aileron does not do, while ‘taking over a great deal of the work the aileron does. He finds that the up-tilted wing-tip as he has adapted it to the pres- ent-day plane not only keeps a glme on an even keel and pre- B ents side-slipping in turning, but that it will allow the pilot to relinquish the controls of his ship and keep the plane on an even, straight course. Tests with the Hocke wing tips, he says, have %roved conclusively their value in blind flying. Time after time, he says, his pilot, Haynes, has put the ship through thunder heads, relinquished the controls and come out into clear sky to find himself flying along the same even, straight course he was on before entering the clouds. The time will come, Hocke be- ciple applied by birds to their wrnu-tir, up-tilted feathers, can be applied to man’s flight, as will, he believes, be applied a great many other principles of bird flight. With his circular swing Hocke plans to continue his study of the flight of birds for application of other principles he expects them to teach him. -— LONG BEACH PREPARES BIG SEND-OFF FOR RACE Pistol Fired in Chicago Will Start Women's Western Derby at Jubilee Exhibition.

SUNDAY CHICAGO, August 9.—Lucky the man who can spend the month of Au- gust touring in his motor car, says a bulletin for Summer tourists just issued by the American Research Foundation. “Road conditions will be at their best in August this year,” the bulletin asserts, “and at the very center,of the United States will be one of the biggest thrill events of the year which the August tourist can include on his trip. “The 1930 national air races will be held in Chicago from August 23 to September 1, inclusive, offering the greatest aerial pageant in the history of human flight. Situated as Chicago is, at the crossroads of many modernly improved National and State high- ways, it will be easy for tourists to route their trip so as to be in Chicago for this event. Every form of aero- nautical activity will be included on the program, including races for large planes and small, civil aircraft and service planes, parachute-jumping con- tests and scores of novelty events. The meet is expected to attract more than one-fourth of the 6,000 licensed air- planes in the United States, including Army, Navy, Marine Corps and Na- tional Guard ships.” En route to Chicago the tourist will find many added delights, whether he comes from North, South, East or West. The Lincoln Highway East and West | from Chicago, the Dixie Highway ex- tending to the South and Wisconsin's labyrinth of modernized highways as- sure the tourist of easy entree to the city. Arriving in Chicago, he will find & system of boulevards aggregating 130 miles, including the world famous Lake Shore drive, extending more than 30 miles along the very shores of Lake Michigan, through parks and play- grounds more expansive than any other city in American can boast. One-day side trips from Chicago, the bulletin points out, are almost too numerous to catalogue, but the most popular ones include a tour through the celebrated sand dune resorts of Northern Indiana and Southern Mich- igan over a road that skirts the south- ern tip of Lake Michigan, a trip to the lakes and dells region of Southern Wisconsin and a one-day tour to Cen- tral Illinois and Starved Rock, a spot made famous by the last stand of a little band of Indians who starved to death on the great rock overhanging the Illinois River rather than surrender to_their enemies. Paved roads are so numerous in the Middle West, the bulletin states, that there is no need to travel on dirt or gravel. Illinois leads all States of the Union in hard road mileage. But for the motorist who enjoys loafing along the less crowded highways there is an abundance of highly modernized dirt and gravel roadway in the Chicago territory, particularly in Indiana and ‘Wisconsin. These roads will be at their best in late August when the loose gravel of early Summer has been settled and the oiled sections will be comfort- ably dried. TROPICS “REPRODUCED” Illinois Heat Wave Gives Photo Students New Problem. The hardships of aerial photograph in the tropics were visited upon students of the photographic officers’ class at the Air Corps Technical School, Chanute Field, Rantoul, Ill, before their recent graduation, the War Department has formed. Mapping flights were made in the morning and completed mosaic maps delivered before noon by the students. On the first day it was necessary to use tropical ~developers, hardening baths and quick drying methods to prevent rining of the negatives because of the hot weather, the temperature reaching 100 degrees in the shade.

PASSENGER AIRPLANES FLYING 91,361 MILES ON DAILY ROUTE Passenger airplanes on regularly scheduled air transport lines in the United States are flying & total of 91,361 miles every day, or nearly four times the distance around the earth at the Equator, and are serving 226 cities on regular daily schedule, according to the semi-annual report of the American Air Transport Association. Despite the general depression in the aviation industry during the past year, the growth of air passenger lines has been going forward steadily, it was pointed out. A year ago passenger- carrying aircraft flew a daily total of 61,025 miles and stopped at 151 points. 18 New Companies Enter Field. In the faece of adverse financial conditions, 18 new companies have gone into the air transport business during the past year and there are today a total of 39 companies carrying pas- sengers by air on regular schedule, where there were but 21 companies year ago. 4 ‘The passenger airways system has in- creased from approximately 25,000 miles last year to a present total of 32,803 miles.

In addition to these extensive opera- tions in the United States, American alr transport operators are extending their lines to all parts of the New World. American owned and operated mail and_passenger planes are flying over 12476 miles of Mexican, West Indian, Central and South American airways. Nineteen countries are con- | nected to the United States by air and | planes are flying more than 26,000 miles | daily in these foreign services. “Airports of Entry” Established. ‘The Federal Government has estab- lished a score of airports, known as “airports of entry,” to provide customs facilities to planes arriving in the United States from Canada, Mexico, the West Indies, Central and South America. | Nearly all of these ports have been established during the past year. For the benefit of air travelers | throughout the country, the association, which represents 21 companies operating airmall and passenger planes on estab- lished routes, has issued a consolidated | time table of air-travel schedules and | fares in the United States and to foreign | countries. This time table, it is ex- plained, shows that through connecting lines and schedules it is possible to fly to any part of the United States and to many parts of the Western Hemisphere, Two-day service from the Atlantic to the Pacific Coast is available and it is possible to leave the National Capital at noon one day and be in San Francisco or Los Angeles the following afternoon.

The progress in gliders, achievements of motor designers and refinements of aircraft will pass in review in an epic of stirring events, prizes for which total more than $100,000. Dozens of flyers will race from every corner of the country in five derbies and more than 2,000 airplanes are ex- pected to make Chicago the aviation center of the hemisphere for a week. Civilian flyers will dominate the races this year for the first time. The num- ber of civillan events far outgumbers those in which Army and Navy pilots will participate. The greatest single event will be the Thompson trophy race, an international free-for-all speed contest for §10,000 and a gold and silver emblem, The glider entries for the races were led off by Hawley Bowlus, who inter- ested Lindbergh in the sport. The interest of young America in fly- ing will be reflected in a national air- plane model competition. Famous._flyers expected to attend the races include Col. Lindbergh, Rear Ad- miral Richard E.
