HAZEUIURST FIELD

MINEOLA, L. I.

As there are numerous young men training in this country, both in ground schools and at flying fields for the aviation service, and as much of this will probably be performed in France, it seems desirable to compile a brief glossary of commonly used aviation terms in both French and English to facilitate intercourse between the pilots and mechanics speaking different languages who work together in the present emergency.

These lists are enlarged from a briefer series prepared originally for use in teaching classes at the Signal Corps Aviation School, Mineola, L. I. The illustrations accom- panying the text should make everything clear about which any doubt could exist. As no definitions are given, the booklet is more in the, nature of a glossary or list of words than a dictionary, and is intended only for use of those already familiar with aviation. Some of the equivalents may not be literally correct, but are selected with a view to listing only terms in common, everyday usage.

The painstaking work of Lieut. Paul Montariol, of the French Flying Corps, assigned as instruction officer at Mineola, L. I., has been of great value in furnishing French equivalents and insures that these will conform to the accepted practice abroad. It is believed that this

compilation will be of some value in securing closer co- operation and more intelligent discussion of aviation subjects between members of our oversea aviation forces and our non-English speaking allies.

Metric System and English Equivalents.

The Metric System is based on the Meter which was designed to be one ten-millionth (rsreVTOs) P?rt °f the earth's meridian, passing through Dunkirk and Formentera. I^ater investigations, however, have shown that the Meter exceeds one ten-millionth part by almost one part in 6400. The value of the Meter, as authorized by the U. S. Government is 39.37 inches. The Metric system was legalized by the U.S. Government in 1866.

The three principal units are the meter, the unit of length, the liter, the unit of capacity, and the gram, the unit of weight. Multiples of these are obtained by prefixing the Greek words: deka (10), hekto (LOO), and kilo (1000). Divisions are obtained by prefixing the I<atin words: deci (fa), centi (rfo)i and^ milli (TJS^). Abbreviations of the multiples begin;with a capital letter, and. of the divisions with a small letter, as in. the following tables :

Measures of Length

10 millimeters (mm.) -= 1 centimeter (cm.) =.3937 in.

10 centimeters. = 1 decimeter (dm.)

10 decimeters . = 1 meter (m.) =3.28083 f t.=39 .37 ins.

10 meters ; = 1 dekameter (Dm.)

10 dekameters = 1 hektometer (Hm.)

10 hektometers = 1 kilometer (Km.) ....... . .=0.62137 mile

1 foot "...= .3048meter

1 inch = 25.4 millimeters

Measures of Surface (not Land)

100 square millimeters (mm. 2) = l square centimeter (cm. 2)= 0.155sq. in.

100 square centimeters ..= 1 square decimeter (dm. 2)

100 square decimeters »= 1 square meter (m, 2) •=10.764sq. ft.

1 square vard = .836 square meter

1 square foot = .0929 square meter

1 square inch = 645. 2 square millimeters

Measures of Volume

1000 cubic millimeters (mm. 3) =1 cubic centimeter (cm. 3) = .061 cu.in.

10110 cubic centimeters =1 cubic decimeter (dm.3)=l liter=61.023 cu.ins.

1000 cubic decimeters =1 cubic meter (m. 3) =35. 314 cu.ft. =264. 2 gallons

1 cubic yard = .7645 cubic meter

1 cubjc foot = .02832 cubic meter

1 cubic inch = 16.387 cubic centimeters

Measures of Capacity

10 milliliters (ml.) — 1 centiliter (cl.)

10 centiliters — 1 deciliter (dl.)

10 deciliters. — 1 liter (!.)=!. 0567 qts.(Ur.S.)=61.023 cu.ins.

10 liters. = 1 dekaliter (Dl.)

10 dekaliters = 1 hektoliter (HI.)

10 hektoliter = 1 kiloliter (Kl.)

1 gallon (U.S.) = 3.785 liters

1 gallon (British) .= 4.543 liters

Measures of Weight

10 milligrams (mg.) — 1 centigram (eg.)

10 centigrams = 1 decigram (dg.)

10 decigrams — 1 gram (g.) ..."-IS. 432 grains

10 grams — 1 dekagram (Dg.)

10 dekagrams = 1 hektogram (Hg.)

10 hektograms = 1 kilogram (Kg.) ....... .—2.2046 pounds

1000 kilograms — 1 ton (T) = .9842 ton of 2240 pounds

NOTE— The gram is the weight of one cubic centimeter of pure -distilled water at a temperature of 3'J.2°P.; the kilogram is the weight of 1 liter of water; the ton is the weight of 1 cubic meter of water.

1 grain 0648 gram' I ounce (Avd.) — 28. 35 grams

THE WHOLE FIELD OF MECHANICAL MOVE*

MENTS COVERED BY MR. HISCOX'S.

TWO BOOKS

We publish two books by Gardner D. Hiscox that will keep you from "inventing" things that have been done be- fore, and suggest ways of doing things that you have not thought of before. Many a man spends time and money, pondering over some mechanical problem, only to learn, after he has solved the problem, that the same thing has been accomplished and put in practice by others long before. Time and money spent in an effort to accomplish what has al- ready been accomplished are time and money lost. The whole field of mechanics, every known mechanical movement, and practically every device is covered by these two books. If the thing you want has been invented, it is illustrated in them. If it hasn'fl been invented, then you'll find in them the nearest things to what you want, some movement or device that will apply in your case, perhaps; or which will give you a key from 'which to work. No book or set of books ever published is of more real value to the inventor, draftsman or practical mechanic than the two volumes de* scribed below.

MECHANICAL MOVEMENTS, POWERS AND DEVICES. By GARDNER D. Hiscox. This is a collection of 1,890 engravings of different mechanical motions and appli- ances, accompanied by appropriate text, making it a book of great value to the inventor, the draftsman, and to all read- ers with mechanical tastes. The book is divided into eighteen sections or chapters, in which the subject-matter is classified under the following heads: Mechanical Powers; Transmis- sion of Power; Measurement of Power; Steam Power; Air Power Appliances; Electric Power and Construction; Navi- gation and Roads; Gearing; Motion and Devices; Control- ling Motion; Horological; Mining; Mill^ and Factory Appli- ances; Construction and Devices; Drafting Devices; Miscel- laneous Devices, etc. Fourteenth edition. 400 octavo pages.

MARINE ENGINES AND "BOILERS, THEIR DESIGN AND CONSTRUCTION. By DR. G. BAUER, LESLIE S. ROBERTSON and S. BRYAN DONKIN. In the words of Dr. Bauer, the present work owes its origin to an oft felt want of a condensed treatise embodying the theoretical and practical "rules used in designing marine engines and boilers. The need of such a work has been felt by most engineers engaged in the construction and working of marine engines, not only by the younger men, but also by those of greater experience. The fact that the original German work was written by the chief engineer of the famous Vulcan Works, Stettin, is in itself a guarantee that this book is in all respects thoroughly up-to-date, and that it embodies all the information which is necessary for the design and con- struction of the highest types of marine engines and boilers. It may be said that the motive power which Dr. Bauer has placed in the fast German liners that have been turned out of late years from the Stettin Works represent the very best practice in marine engineering of the present day_. The work is clearly written, thoroughly systematic, theoretically sound; while the character of the plans, drawings, tables, and sta- tistics is without reproach. The illustrations are careful re- productions from actual working drawings, with some well- executed photographic views of completed engines and boilers. 744 pages, 550 illustrations and numerous tables.

TURBINES

MARINE STEAM TURBINES. By DR. G. BAUER and O. LASCHE. Assisted by E. Ludwig and H. Vogel. Translated from the German and edited by M. G. S. Swallow. The book is essentially practical and discusses turbines in which the full expansion of steam passes through a number of separate turbines arranged for driving two or more shafts, as in the Parsons system, and turbines in which the complete expansion of steam from inlet to exhaust pressure occurs in a turbine on one shaft, as in the case of the Curtis machines. It will enable a designer to carry out all the ordinary calcu- lation necessary for the construction of steam turbines, hence it fills a want which is hardly met by larger and more theo- retical works. Numerous tables, curves and diagrams will be found, which explain with remarkable lucidity the reason why turbine blades are designed as they are, the course which steam takes through turbines of various types, the thermody- namics of steam turbine calculation, the influence of vacuum on steam consumption of steam turbines, etc. In a word, the very information which a designer and buildec- of steam turbines most requires.
