International Organization for Standardization Case postale 56 o CH-121 1 Genve 20 o Switzerland Printed in Switzerland 1151 PT 3-89 4853903 O068629 5 r IS0 1151-3 : 1989 (E) Foreword IS0 (the International Organization for Stand
11、ardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right
12、to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft Internat
13、ional Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International
14、Standard IS0 1151-3 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles. This second edition cancels and replaces the first edition (IS0 1151-3 : 19721, of which it constitutes a technical revision. Users should note that all International Standards undergo revision from time
15、to time and that any reference made herein to any other International Sfandard implies its latest edition, unless otherwise stated. iii 7- - 1151 PT 3-89 3 Y851903 0068630 1 IS0 1151-3 : 1989 (E) IC0 1151, Flight dynamics - Concepts, quantities and symbols, comprises, at present, seven parts: Part I
16、: Aircraft motion relative to the air. Part 2: Motions of the aircraft and the atmosphere relative to the Earth. Part 3: Derivatives of forces, moments and their coefficients. Part 4: Parameters used in the study of aircraft stability and control. Part 5: Quantities used in measurements. Part 6: Air
17、craft geometry. Part 7: Flight points and flight envelopes. IC0 1151 is intended to introduce the main concepts, to include the more important terms used in theoretical and experimental studies and, as far as possible, to give cor- responding symbols. In all the parts comprising IS0 1151, the term “
18、aircraft“ denotes a vehicle intnded for atmosphere or space flight. Usually, it has an essentially port and starboard symmetry with respect to a plane. That plane is determined by the geometric characteristics of the aircraft, In that plane, two orthogonal directions are defined: fore-and-aft and do
19、rsal-ventral. The transverse direction, on the perpendicular to that plane, follows. When there is a single plane of symmetry, it is the reference plane of the aircraft. When there is more than one plane of symmetry, or when there is none, it is necessary to choose a reference plane. In the former c
20、ase, the reference plane is one of the planes of symmetry. In the latter case, the reference plane is arbitrary. In all cases, it is necessary to specify the choice made. Angles of rotation, angular velocities and moments about any axis are positive clockwise when viewed in the positive direction of
21、 that axis. All the axis systems are three-dimensional, orthogonal and right-handed, which implies that a positive rotation through n/2 around thex-axis brings the y-axis into the position previously occupied by the z-axis. The centre of gravity coincides with the centre of mass if the field of grav
22、ity is homogeneous. If this is not the case, the centre of gravity can be replaced by the centre of mass in the definitions of IS0 1151; in this case, this should be indicated. Numbering of sections and clauses With the aim of easing the indication of references from a section or a clause, a decimal
23、 numbering system has been adopted such that the first figure is the number of the part of SO 1151 considered. iv 3353 PT 3-89 I4853903 0068633 3 r _ _ INTERNATIONAL STANDARD IS0 1151-3 : 1989 (E) Flight dynamics - Concepts, quantities and symbols - Part 3: Derivatives of forces, moments and their c
24、oefficients 3.0 Introduction This part of IS0 1151 deals with derivatives of forces, moments and of other quantities characterizing such forces and moments. The term “derivative“ designates the partial derivative of a function with respect to an independent variable. These derivatives appear in the
