4、909 of a Committee to prepare a preliminary list of terms peculiar to aeronautics, which was issued in1910, a revised and extended list appearing in1994. The Committee was reorganized in1916 and the first complete glossary was published in1918. In 1920, at the request of the Royal Aeronautical Socie

5、ty, the work was taken over by the British Standards Institution and the first British Standard Glossary of aeronautical terms was issued as BS185 in 1923, a revised edition being published in1933. A further revised provisional edition, for war time use, was issued in1940. Further revised editions,

6、which were necessitated by the rapid development of aeronautics, were published in19501951, and in19621965. Many new terms, in particular in the field of gas turbines and jet propulsion, were included in the former and new sections covering terms relating to ballistic and guided missiles, personnel

7、and aviation medicine were introduced during the latter revision. The present revised edition has been prepared to take account of development since1965. In particular, it includes a new subsection in Section3 dealing with fatigue terms and new sections covering terms relating to aerial survey and a

8、stronautics. The title of the glossary has also been amended to take account ofthe latter new section. The revised glossary will comprise the following sections: Section 1: General; Section 2: Motion of aircraft; Section 3: Structures; Section 4: Aerodynamics; Section 5: Heavier-than-air aircraft (A

9、erodynes); Section 6: Ballistic and guided missiles; Section 7: Lighter-than-air aircraft (Aerostats); Section 8: Power plant; Section 9: Propellers; Section 10: Auxiliary services; Section 11: (Not allotted); Section 12: Parachutes; Section 13: Air-traffic and ground services; Section 14: Radiocomm

10、unication and radiolocation; Section 15: Meteorology; Section 16: Personnel; Section 17: Aerospace medicine; Section 18: Astronautics. The revision is published in loose-leaf form to enable the various sections to be issued as they are completed, and to facilitate the task of keeping the glossary up

11、 to date as far as is practicable. As a result, it will be found that, until all the revised sections have been published, some terms appearing in particular sections in the19621965 edition also appear in different sections in this edition with revised definitions: in such cases the latter only are

12、referred to in the revised index and these should be taken as the standard definitions e.g.the definition of “rectified airspeed” is that given in Term No.4320 in this edition, not TermNo.11133 in the previous edition). It is recognized that some of the sections may need review immediately upon the

13、completion of the current revision, to take account of usages established during the period over which it has been prepared.BS185-1:1969 BSI 11-1999 iii The object of the glossary is to provide standard definitions of technical terms peculiar to aeronautics, astronautics and related subjects. The co

14、ining of new terms has been avoided, the work being confined to the crystalization of existing terms in their best accepted usage. Terms in general use in other branches of engineering are only included where they have some special significance in aeronautics or astronautics. The descriptions used b

15、y official bodies in identifying and purchasing some classes of stores are those specified, in accordance with NATO Codification System, by the Ministry of Defence (Defence Codification Authority); they do not necessarily agree with the generally accepted terms given in this glossary. Where two or m

16、ore synonymous terms are in use, the term which is favoured is given first, with the intention that it should gradually displace the other. The alternative terms are given below the preferred terms in less prominent type. While purporting to give the generally accepted meaning of term, a definition

17、should not be regarded as in any case taking the place of a specification. Each definition has assigned to it a4-digit or5-digit number. The first one (or two) digits, in the thousands place, represents the section. This section number with the following digit in the hundreds place represents the su

18、bsection. The last two digits represent the position of the definition in the subsection. Thus definition2225 is the25th definition of Subsection22, which is in Section2. The general arrangement of the items in each subsection, and in groups under a subsection, is alphabetical. It has, however, been

19、 considered desirable in certain cases to bring related terms together under a heading or a general definition, and these terms are printed in a distinctive italic type. In the definitions, terms which are not defined in the glossary but which it is thought desirable to include in the index are prin

20、ted in bold-face type. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages T
