As a simulation of road driving, wind tunnel testing of full-size vehicles produces certain errors in the aerodynamic forces, aerodynamic moments, and surface pressures. The magnitude of these errors, in general, depends on the following: a.) Flow quality, b.) Determination of the reference dynamic pressure, c.) Wind tunnel floor boundary layer, d.) Test section geometry and position of the car within that geometry, e.) Shape of the vehicle, f.) Blockage ratio: The ratio of the cross-sectional area of the vehicle to the cross-sectional area of the wind tunnel nozzle, g.) Wheel rotation, and h.) Internal flow in the model. The SAE Standards Committee, Open Throat Wind Tunnel Adjustments, had as a goal to document the knowledge of the influence of model interference on wind tunnel test results for automotive open jet wind tunnels. This document contains the following information related to this subject: a.) Design data of open throat wind tunnels, b.)

AIR4276
This Aerospace Information Report (AIR) is the primary vehicle for providing the survey results to industry and government. The Institute of Defense Analysis (IDA), has performed a study which concludes that computerized techniques must be developed to integrate RM&S into product design in order to permit design influence from inception throughout the product life cycle. This AIR addresses the DoD initiative for developing Computer Aided Acquisition and Logistic Support (CALS) and industry's role in its evolution. AIR 4276 provides the detailed results of an industry/government survey inquiring into the extent of computerization of RM&S into the design process. Background information describes the evolution of the survey and why it was developed.

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.

This standard provides data and guidance for the design, manufacture, and inspection of straight, non-helical, cylindrical involute splines. It establishes a specification based on the metric module within the range 0.25-10 inclusive, relating to nominal pressure angles of 30 deg, 37.5 deg, and 45 deg. For computer programming, the term "37.5 deg" has been adopted instead of "37 deg, 30 min". Limiting dimensions, variations, and manufacturing tolerances and their effect on the fit between connecting co-axial spline elements, are defined and tabulated. Linear dimensions are expressed in millimeters and micrometers. Angular dimensions are expressed in degrees and decimal degrees.

Many different computer programs have been developed to determine performance capabilities of aircraft environmental control systems, and to calculate size and weight tradeoffs during preliminary design. Many of these computer programs are limited in scope to a particular arrangement of components for a specific application. General techniques, providing flexibility to handle varied types of ECS configurations and different requirements (i.e., during conceptual or preliminary design, development, testing, production, and operation) are designated "company proprietary" and are not available for industry-wide use. This document describes capabilities, limitations, and potentials of a particular computer program which provides a general ECS analysis capability, and is available for use in industry. This program, names AECS1, was developed under the sponsorship of the U.S. Air Force Flight Dynamics Laboratory (References 1 and 2).

ARP 1834 provides general guidance for the selection, approach to, and performance of various kinds of F/FA of digital systems and equipment. Its prime objective is to present several industry-acceptable, cost-effective methods for identifying, analyzing, and documenting digital-equipment failure modes and their effects. The analysis techniques and considerations presented here are directed to digital-equipment hardware faults and failures exclusively. ARP 1834 is not intended as an exhaustive treatment of the enormously complex process involved in the analytical failure evaluation of complete digital systems, nor as a universally applicable, definitive listing of the necessary and sufficient steps and actions for such evaluation.

AS8043
This Aerospace Standard specifies laboratory test procedures and minimal requirements for the manufacturer of torso restraint systems for use in small fixed wing aircraft and rotorcraft. It is intended to establish a minimum level of quality which can be called upon by the designer of those systems. However, compliance with this standard alone may not assure adequate performance for the restraint system under normal and emergency conditions. Such performance requires consideration of factors beyond the scope of this standard, and must be demonstrated by a system evaluation procedure which includes the seat, the occupant, the specific restraint installation and the cabin interior configuration.

J1100_198406
This SAE Recommended Practice defines a set of measurements and standard procedures for motor vehicle dimensions. The dimensions are primarily intended to measure the design intent of a vehicle within a design environment (i.e., CAD). All dimensions in this practice can be measured this way. In addition, some dimensions can be taken in an actual vehicle. If measurements are taken on physical properties, some differences in values should be expected. Also, care should be taken to not confuse design intent measurements with those taken on a physical property. It is intended that the dimensions and procedures described in this practice be generic in their application to both the HPM, described in SAE J826, and the HPM-II, described in SAE J4002. In some circumstances, the figures may only reflect one or the other.

This document establishes a uniform method of combining inch-pound units and metric units of measure on the same engineering drawing. In this document 'metric units' means the International System of Units (abbreviated SI) as described in SAE J 916. Herein is guidance for converting from one system to the other while maintaining functional interchangeability. This document covers a dual dimensioning practice that provides both U.S. Customary inch-pound units and SI metric units for all dimensions on the field of drawing. The scope does not include the 'chart method'—whereby drawings are dimensioned only in SI units—with conversions to inch-pound units provided in chart form (usually computer generated) on the drawing. Further information on the chart method is found in SAE Handbook Supplement J1066, 'Recommended Guidelines for Company Metrication Programs in the Metalworking Industry.'

Three levels of fan structural analysis are included in this practice: 1. Initial Structural Integrity 2. In-vehicle Testing 3. Durability Test Methods The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The In-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The Durability Test Methods section describes the detailed test procedures that may be used depending on type of fan, equipment availability, and end objective. Each of the previous levels builds upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design.
