10、S -,-,- iii Introduction This Specifi cation Format has been prepared as a guide for the preparation of a single-degree-of-freedom spring- restrained rate gyro specifi cation. Prepared by the Gyro and Accelerometer Panel of the Aerospace Electronic Systems Group of the Institute of Electrical and El
11、ectronics Engineers, this format provides a common meeting ground of terminology and practice for manufacturers and users. Two other documents, Aerospace Industries Association EETC Report No. 5 (Revision A), “Standard Gyro Terminology,”* and IEEE Standards Publication No. 293, “Test Procedure for S
12、ingle-Degree-of-Freedom Spring- Restrained Rate Gyros,” have been utilized in the preparation of this format. This format will be limited to conventional single-degree-of-freedom spring-restrained rate gyros. A model equation is given in paragraph 6.3 for reference, and is to be included in a specif
13、i cation only to the extent necessary. Table 1, on this page, lists various rate gyro design features for which this format is applicable. The table is not intended to make any suggestion regarding the selection of particular design features that might restrict the free choice of manufacturers. Blan
14、k spaces are provided in the Specifi cation Format for the insertion of specifi c values. Brackets are used to designate possible alternates. Boxed information is intended for explanatory purposes. Figures 1, 2, and 3 are to be used as a guide for the preparation of specifi c fi gures or drawings. T
15、he user is cautioned not to overspecify. Only those parameters that are required to guarantee proper instrument performance in the intended usage should be controlled. * Available from: National Standards Association, Inc. 1321 Fourteenth Street N.W.
