Alcohol, Methyl

1989-07-01
HISTORICAL
AMS3004D
This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of August 2009. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required on some existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. “NONCURRENT” specifications are available from SAE upon request.

Magnetic Particles, Fluorescent, Wet Method, Oil Vehicle Ready-to-Use

1989-07-01
HISTORICAL
AMS3045B
This specification covers fluorescent magnetic particles in the form of a mixed, ready to use suspension in an odorless inspection oil vehicle. These particles have been used typically as the inspection medium in a wet method, magnetic inspection system as defined in ASTM E 1444, but usage is not limited to such application.

Gas Turbine Engine Performance Presentation for Digital Computer Programs Using Fortran 77

1989-07-01
HISTORICAL
ARP4191
This SAE Aerospace Recommended Paractice (ARP) provides a method for digital computer programs for gas turbine engine performance, steady-state or transient, performance to be written using the FORTRAN 77 language. When it is agreed between the program User and Supplier that a particular program shall be supplied in FORTRAN 77, it is recommended that this ARP be used in conjunction with AS681 for steady-state and transient programs. This ARP also describes how to take advantage of the FORTRAN 77 CHARACTER storage to extend the information interface between the calling program and the engine subroutine. The ARP has the same major section numbers as AS681 to facilitate its use with this document. The information given in each section of this ARP is additional to that given in AS 681.

INSTRUMENTAL METHODS OF DETERMINING SURFACE CLEANLINESS

1989-07-01
HISTORICAL
ARP4252
This Aerospace Recommended Practice is intended as a guide toward standard practices for the determination of surface cleanliness that are applicable to field operation. Some of these methods can also be used to determine quality assurance that a surface has been properly prepared and maintained. The instrumental methods are: Wettability, Surface Potential Difference (SPD), Ellipsometry, and Optically Stimulated Electron Emission (OSEE). Each instrument is described with respect to measurement techniques, limitations, and advantages and types of available instruments. Elementary theoretical principles and examples of the use of each instrument are also given.

Acoustical Considerations for Aircraft Environmental Control System Design

1989-07-01
HISTORICAL
AIR1826
This Aerospace Information Report (AIR) is limited in scope to the general consideration of environmental control system noise and its effect on occupant comfort. Additional information on the control of environmental control system noise may be found in the bibliography and in the documents referenced throughout the text. This document does not contain sufficient direction and detail to accomplish effective and complete acoustic designs.
