DURING the course of a conversation, a well known pilot brought out the fact that the flying boat for commercial purposes seemed to be dropping out of use. As one of the staff of AVIATION owns and flies a “boat,” the remark naturally caused discussion.
Water Recovery is now in use as regular equipment on the airships Shenandoah and Los Angeles, and it has been conclusively demonstrated that an amount of water can be recovered from the exhaust gases from the engines, in flight, which more than equals the weight of fuel consumed in producing those exhaust gases.
The French navy has been developing rather an interesting type of plane for use on ship board and for oversea reconnaisance. The normal land machine if it has a forced landing on the water will in most cases nose over as soon as the wheels and landing gear touch the water.
Foundations are complete and steel work is well under way on the largest airship mooring tower in the world, located at the Ford Airport in Dearborn. The tower, according to present schedules, will be ready for use early in July. A visit during the summer from one of the great naval airships may be expected as a first test of the unusual engineering features of its design.
The Air Service has released for sale, for use exclusively for flying purposes within the territorial limits of the United States, one hundred and seventy (170) new Liberty “12” 400 hp. airplane engines, which are stored at the Little Rock Air Intermediate Depot, Little Rock, Ark.
The second edition of “Who’s Who in American Aeronautics” will be published Sept. 1, 1923. Below will be found new biographies that will appear in the forthcoming volume. An invitation is extended to all pilots actively engaged in aviation military, naval or commercial to send their biographical sketches for insertion in the next issue.
<p>A very interesting paper entitled “Some Fatigue Tests on Non-Ferrous Metals,” by R. R. Moore, was read at the Twenty-eighth Annual Meeting of the American Society for Testing Materials at Atlantic City. In this paper are given the results of tests on non-ferrous metals to determine their endurance limits when subjected to alternating stresses of tension and compression, produced by the rotating beam method.</p>
All Surplus OX5s Sold by Air Service To Be Used in Motor Boats
All the surplus OX5 engines remaining on hand in the Air Service have been sold by public auction. There were 160 bidders for the 2800 engines and they were were awarded to 14 bidders. Quantities of spare parts and tools for Curtiss OX5 engines located at the Fairfield Air Intermediate Depot, Fairfield, Ohio, and the Rockwell Air Intermediate Depot, Coronado, Calif., were included without extra charge to the purchaser taking all or the bulk of this type of engine.
Recently there have appeared in newspapers what purport to be the cost to the Ford Company of air transport of freight. Enquiry as to the reliability of these cests showed that the figures were neither authentic nor authorized and as yet no attempt has been made to prepare cost data.
Description of the Twin Disc Clutch Co.’s Friction Clutches and Gears for the Airship RS-1 Built by the Goodyear Tire and Rubber Co.
<p>In 1921 the Twin Disc Clutch Co. of Racine, Wis., designed and built for the Goodyear Tire and Rubber Co. two 150 hp. aircraft clutches for use in the Army airship AC-1. This design was described in AVIATION for Jan. 23, 1922. These clutches have had some 400 hr.</p>
<p>In connection with the standardization of instruments used in the wind tunnel, this investigation was undertaken by Elliott G. Reid at Langley Memorial Aeronautical Laboratory, to determine the nature and magnitude of the errors inherent in the measurement of air speed by a Pitot tube when the instrument is mounted close to some other body.</p>
Although still comprising only a very small portion of the total shipments of automotive products from the United States, aircraft exports in 1924 were almost double those of 1923. Their value was $798,273, or $364,715 more than in 1923, and the number of planes exported exceeded those of the previous year by 10.
Rodgers Field, the Pittsburgh municipal airdrome, became a reality last week upon the completion of the grading operations. It is a two-way field of 40 acres, owned jointly by the city of Pittsburgh and the county of Allegheny. It is also an Army Reserve Training Field, the Governemnt having already constructed two all-steel hangars and fueling station at an expense of $60,000.
Nineteen officers and 72 men gathered here the last two weeks in June to attend the maneuvers of the 116th Observation Unit of the Washington National Guard in annual encampment. The officers kept four ships in the air almost continuously and every private in the squadron was given a ride which included stunting.
New types of commercial airplanes now being developed are expected to be brought together for comparison and competition in the aerial exposition and field meet to be held in Tulsa, Okla., Aug. 30 to Sept. 4, in connection with the national encampment of Veterans of Foreign Wars.
Well, the boys did it. Not so very long ago we made the rounds vociferously complaining that if things did not liven up pretty soon, aeronautical reporters on Dayton papers would become about as useful as brakemen on the Ford air line. But now we are willing to haul up the white flag.
Varney Airport, Peoria’s municipal flying field, which is located about one mile north and a quarter mile west of the fair grounds (about four miles north and a half mile west from the center of the city) has been improved till it is now one of the best fields in the middle west.
A conference of the O.D.V.F. or Friends of Aviaion Society, which has become a gigantic Soviet State organization was held May 15. According to official figures, the O.D.V.F. has a membership of 225,000 persons, of whom 47 per cent are workmen and 30 per cent are officials who have contributed more than 7,000,000 gold rubles toward strengthening the Red air force.
The following table shows the aerial activities in Argentine for the year of 1924 and the latter part of the year 1923. These data show that our southern neighbors’ interest in aeronautics is very rapidly increasing. It is noteworthy that the greatest amount of time is spent on instruction.
Hon. Dwight F. Davis, Acting Secretary of War, has just approved a new and far-reaching policy which will afford an opportunity for Air Service training to Army officers of all combat branches. This change is prompted by aviation developments leading to a conclusion that all line officers require such knowledge of the capabilities and limitations of the Air Service, as to permit them using it under all conditions of battle, and to a feeling that the general efficiency of such officers will be increased by a limited amount of actual experience in the air.
Secretary of the Navy Wilbur announced June 20 that Capt. Stanford E. Moses, U.S.N., commander of the battle fleet aircraft squadrons, has been placed in command of the forthcoming West Coast-Hawaiian flight. It has not been definitely decided whether the start of the flight will be made from San Francisco or San Diego.
The accounts that have been sent by cable of the great crowds and the enthusiasm aroused in Germany by the Rundflug and in England by the R.A.F. Pageant should give those who are in a position to direct the trend of aeronautical meets in this country a very plain object lesson.
