Big Demand for Aircraft. There is a tremendous demand for aircraft in the United States today and manufacturers of eve type of airplane are hard presses to fill orders already booked, Ina way this situation is unfortunate. ‘When such & boom is in progress manufacturers are likely ive for production rather than for the improvement of their product except as may be necessary to meet the immediate demands of thelr purchasers. At this %oinr.. however—luckily for the public and aviation—the research organizations, which are not working so much for the money that it brlnrn in as they are for the sake of the work in hand and a desire for honest rogress, step in to keep scien- ific advancement in line with physical development. The importance of this work cannot be over-estimated. C. G. Grey, one of the greatest British aeronautical authorities, speaking of the necessity for thorough re- search work, says: “The more one thinks over this subject the more one envies America the pos- session of Mr. Daniel Guggenheim and Mr. Harry Guggenheim and the very sound, practical council which initiates the various phases of th’, work of the Guggenheim Continuing his discourse on re- search, Mr. Grey, whose widely known and eloquent admiration of all things British makes any word of his in praise of anything American amount almost to a benediction, says: Research Plans Outlined. . “Research is of two kinds, that which is known as ‘basic’ research, and that which is known as ‘ad . hoc’ research. In the former kind ! seekers after truth dig around blindly, working on more or less established scientific facts, in the hope that something may turn up. In the latter kind deliberate re- search is made to er a cer-' tain thing—ad hoc meaning ‘to this,’ the word ‘object’ or ‘end’ being understood. “Occasionally in ad hoc re- search for one thing quite a dif- ferent thing, or a different appli- cation of the same thing, may be discovered accidentally—as, for example, the usefulness of the Handy Page slot in assuring con- trol below stalling point, when in fact search was being made for a method of improving lift and slowing landing-speeds. Basic research may by sheer luck dis- cover something which revolu- tionises the whole industry, or science, with which" it is con- cerned. But, on the whole, the cheapest and quickest way o m g progress is by means of ad hoc research. “That is just where the Ameri- cans have scored over us so far. Over and over their prac- tical aeronaut engineers have started out with ong definite end in view, and they have pursued that end until they have got it. Improved Performance Noted. “The present improved per- formances of aircraft practically all over the world is due primarily work con- shi) r m&d of three miles per hour shows that no hit-or- miss t:icdnlnz can. produce. good Similarly the National Advisory Committee is with the al 1 oroughness into the question -of the oil-burn- compression ignition en; the improvement of _sea) floats and flying boat hulls, the reduction of drag and a multitude of other matters which are bring- ing gray hairs and furrowed brows to American aircraft de- signers, High-speed Wind Tunnel Devised. A new high-speed wind-tunnel has just been installed by the Guggenheim aeronautical labora- tory at the California Institute of 'rechnalog& Pasadens, and it is expected that facts will be un- covered which up to the present time have been beyond the 'flg of science. It is reported that tunnel at a velocity of miles Yer hour, which is so great that t is said if a n ‘were to thrust his hand into the tunnel the force of the wind would sprain his wrist. Other educational institutions which have contributed materially to the science of aviation are the Guggenheim School of Aeronau- tics at New York University and the Massachusetts Institute of Technology. Development of radio beacon service and the gathering and broadcasting of weather data to pilots in flight promise to form one of the vital chapters in pres- ent day improvement of com- mercial aeronautics. The Bureau test laboratory at College Park, beacon station has been in opera- tion for many months. The De- artment of Commerce has estab- ished several radio beacon sta- tions on the Eastern end of the transcontinental airway and fis extending the chain of stations westward. Air transport companies are hard at work on the application of radio to their operations. Along the transcontinental lines they are establishing a great chain of meteorological stations for the gathering and analysis of weather information and a radio and tele- type communication system for sending this information to con- trol points and broadcasting it | Alliance from there to pilots. Discovery by Army Air Corps. ‘The Army Air Corps, following 8ix years of experimental work at Wilbur Wright Field, Dayton, Ohio, has announced the develog— ment of a new cooling fluid to replace water in the systems of water-cooled airplane engines, with a great increase in ency of both motor and plane. Not onlfi is the total wi &t’\t of the cooling fluid tremendously de- creased; but the size and, conse- quently, the weight and wind re- sistance of the radiator, are de- creased as well. There is made possible a reduction in weight of some 120 pounds and an increase in speed, due to raduced drag, of more than 10 milés per hour in the standard Army pursuit plane, the War Department has an- nounced. . From Michigan came a report this week that a variable camber | sort lane wing has been develo] A ‘me is bufltpol: fland flown, three longitudinal sections, hinged together so that the wing curve may be adjusted in flight by the pllot.

Once in the air the wing js flattened out to reduce the curve and in- crease the speed. ; Roof Markers to be Installed.
