Aircraft Virtual Flight Testing and Certification in Off-nominal Multifactorial Situations

The behavior of a 'pilot-automaton-aircraft-operating environment' system (the System) in off-nominal situations with multiple risks can be unpredictably dangerous. Most multifactorial flight scenarios (corner cases) are considered as theoretically improbable. Such anomalies do nonetheless occur in operations and can lead to inconceivable accidents - 'black swan' events.

DO-178C Practical Training

2021-10-20
RTCA DO-178C is the worldwide accepted standard for civil aviation software development and certification. Compliance with the objectives of DO-178C is the primary means for meeting airworthiness requirements and obtaining approval of airborne software in TC/STC/TSO, etc. Even after learning the DO-178C, many people said they still lack of experience and still find it difficult to produce DO-178C compliant airborne software in real applications.

DO-178C Advanced Training

2020-10-14
With the development of Chinese civil aviation industry, more and more people realized the importance of airborne software. During the certification process of previous ARJ21 aircraft, airborne software had captured many concerns. Nowadays the certification process of C919 aircraft has also reached its peak after its maiden flight. In this context, learning how to correctly understand and strictly meet the objectives DO-178C becomes very essential for the people who is developing or is going to develop airborne software.

Real-time Tire Imbalance Detection Using ABS Wheel Speed Sensors

2011-11-15
This presentation proposes an approach to use ABS wheel speed sensor signals together with other vehicle state information from a brake control module to detect an unbalanced tire or tires in real-time. The proposed approach consists of two-stage algorithms that mix a qualitative method using band-pass filtering with a quantitative parameter identification using conditional least squares. This two-stage approach can improve the robustness of tire imbalance or imbalances. The proposed approach is verified through vehicle testing and the test results show the effectiveness of the approach. Presenter Jianbo Lu, Ford Motor Co.

The Utilization of Flax Fiber Reinforcement in Polypropylene Compounds

2011-11-17
Polypropylene is typically reinforced with commodities that are non renewable and require a great deal of energy to produce. The marketplace needs a reinforcement that can offer beneficial physical properties, such as impact, while being attained from a renewable green source. Compounding flax fiber, which is traditionally an agricultural waste product burned by farmers, with polypropylene yields physical properties similar to traditional glass filled polypropylene. This combination should lead to cost saving opportunities while not sacrificing part performance. Presenter James Preston, Rhetech Inc.

Technical Keynote: State-of-Art of Moire Method and Applications to Shape, Displacement and Strain Measurement

2011-11-17
Moir� method is useful to measure the shape and the whole-field distributions of displacement and strain of structures. There are many kinds of moir� methods such as geometric moir� method, sampling moir� method, Fourier transform moir� method, moir� interferometry, shadow moir� method and moir� topography. Grating method analyzing directly deformation of a grating without any moir� fringe pattern is considered as an extended technique of moire method. Phase analysis of the moire fringe patterns and the grating patterns provides accurate measurements of shapes or displacement and strain distributions. Some applications of these moir� methods and grating methods to dynamic shape and strain distribution measurements of a rotating tire, sub-millimeter displacement measurements from long distance for landslide prediction, real-time shape measurements with micro-meter order accuracy, etc. are shown.

A Method for Testing GPS in Obstructed Environments Where GPS/INS Reference Systems Can Be Ineffective

2011-11-17
When vehicles share certain information wirelessly via Dedicated Short Range Communications (DSRC), they enable a new layer of electronic vehicle safety that, when needed, can generate warnings to drivers and even initiate automatic preventive actions. Vehicle location and velocity provided by Global Navigation Systems (GNSS), including GPS, are key in allowing vehicle path estimation. GNSS is effective in accurately determining a vehicle's location coordinates in most driving environments, but its performance suffers from obstructions in dense urban environments. To combat this, augmentations to GNSS are being contemplated and tested. This testing has been typically done using a reference GNSS system complimented by expensive military-grade inertial sensors, which can still fail to provide adequate reference performance in certain environments.

Fiber Optic Strain Sensor Standardization - International and European Activities

2012-03-16
There are worldwide activities in developing guidelines and standards for fiber optic sensors. Fiber optic sensors (FOS) are increasingly demanded for structural health monitoring purposes and for measurement of physical and chemical quantities because of their specific features. However, they are not yet widely established for practical use due to a lack of guidelines and confirmed standards. Therefore, there are few groups worldwide which are very active in developing standards for use of FOS in different fields, particularly driven from aircraft industry, oil industry or the necessity to provide sensor systems for health monitoring of structures with a certain level of risk. The benefits of guidelines and/or standards on the way to well-validated and well-specified sensor systems will be presented by means of related examples. The presentation will also give an overview on the state-of-the-art and most relevant activities. Results achieved are discussed.
