Developments of experimental and theoretical schemes in engineering disciplines are growing in complexity. Complexity can be attributed to extensive acquisition of measured data as well as higher order levels of computational analysis. Uncertainty is inherent in both experimental and analytical engineering schemes. This session is a collection of current methods and new directions in treating the presence of uncertainty in: 1) data acquisition and analysis and 2) in the mechanical systems.

Abstract Aerodynamic database update from the flight tests using system identification techniques is a crucial tool for the development of control laws and high fidelity simulators. For the certification of aircraft under test, aero-database needs to be validated from flight tests throughout the flight envelope and also to certain levels beyond the envelope boundaries. Validation of aero-database close to envelope boundaries entails additional complexities which necessitates careful handling of flight data identification and update process. This paper discusses the approach adopted for aero-database update and flight clearance, followed by a discussion on the issues relevant in the extreme flight test regimes, such as, flow angle accuracy at higher angles-of-attack, center-of-gravity variation with fuel pitch angle for high-g maneuvering conditions and inaccuracies in Mach number at transonic speeds.

Abstract During the 1930s and 1940s, aircraft designers worked on developing novel design features. Some of these features worked and are commonplace today. Other features fell by the wayside and have been forgotten. These novel design features include laminar flow wings, low-drag cooling systems, buried propulsion systems, canard configurations, jet engines, break-away wing tips, pressure cabins and swept wings. The development and applications of these features will be examined. Specific technical details of these applications will be included in this examination. For the design features that fell by the wayside, the reasons for this outcome will be discussed

Abstract World War 1 began with the airplane as a frail, unarmed means of observing enemy troop movements and ended with the airplane as a powerful, much more evolved weapon of war. There were specialized roles for fighter, bomber and ground attack aircraft as well as newly developed aerial strategies and tactics for operational effectiveness. Many aircraft design technologies greatly matured during the war. Four will be the subject of this paper: Drag reduction, aircraft handling qualities, stability and control, airfoil design technology, and structures design technology. Propulsion and armament also matured greatly but are not discussed in the paper. The discussion of drag reduction will illustrate the innovations of the British on external wire bracing drag, the French on cowl design and the Germans on cantilevered wings and induced drag.

SAE developed this document and associated spreadsheets at the request of automobile manufacturers to help compare products from multiple suppliers using standard data presentation formats. This document includes several preferred formats for presenting acoustical data on materials, components, systems, or vehicles. These formats cover the range of acoustical tests commonly conducted in the automotive industry. These tests follow SAE and ASTM test practices as well as vehicle specific test methods. For each test, the details of samples and test conditions can be entered into an applicable electronic spreadsheet together with the acoustical results data. These data are then linked to standard graphical display(s) for each test. All manufacturers and suppliers in this industry are encouraged to present data and results in these formats.

J2286_201507
This interface document SAE J2286 revises the requirements for file formats as were originally described in SAE J1924. This document describes Interface 1 (I/F 1) in SAE J2461. This document does not imply the use of a specific hardware interface, but may be used with other hardware interfaces such as SAE J1939, ISO 15765 or ISO 14229. The requirements of SAE J2286 supersede the requirements defined by SAE J1924. SAE J2461 establishes the requirements for Interface 1 (I/F 1), as a replacement of the file-based interface described by SAE J1924, as shown by Figure 1. Interface 1 (I/F) is a bi-directional link between the OEM Shop Floor Program (CSCI 1) and the Vendor Component Program (CSCI 2). Using I/F 1, the OEM Shop Floor Program communicates the desired parameters and programming limits for an assembly job to the Vendor Component Program (VCP). In response, the VCP returns programming results to the OEM Shop Floor Program (CSCI 1).

Frequency analysis is often referred to as Fourier analysis but is that really true? The foundation is based on stationary and "Fourier signals." What happens if that is not the case? Modern FFT signal analyzers use very sparse sampling that is correct according to Shannon but what will happen when using time domain analysis. Many of the myths and frequent questions will be answered using a "user perspective" and rules of thumb will be given together with good methods to avoid large errors.

J200_201506
This classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. NOTE 1: The SAE Committee on Automotive Rubber Specifications (CARS) has the sole responsibility for SAE J200. CARS Works closely with and receives input from ASTM Subcommittee D11.30 on Classification of Rubber Compounds with the goal to keep SAE J200 and ASTM D 2000 technically equivalent. Candidate materials presented for development of new tables or for inclusion in Tables A1 or A2 of SAE J200 or Table X1.1 of ASTM D 2000 shall be initiated with the SAE CARS Committee. The procedure to be followed is detailed in Appendix C of SAE J200. NOTE 2: This document may serve many of the needs of other industries in much the same manner as SAE numbered steels.

This standard defines uniform quality and technical requirements relative to metallic parts marking performed using "data matrix symbology" within the aviation, space, and defense industry. ISO/IEC 16022 specifies general requirements (e.g., data character encodation, error correction rules, decoding algorithm). In addition to ISO/IEC 16022 specification, part identification with such symbology is subject to the requirements in this standard to ensure electronic reading of the symbol. The marking processes covered by this standard are as follows: - Dot Peening - Laser - Electro-Chemical Etching Further marking processes will be included, if required. Unless specified otherwise in the contractual business relationship, the company responsible for the design of the part shall determine the location of the data matrix marking. Symbol position should allow optimum illumination from all sides for readability. This standard does not specify information to be encoded.
