Structural health monitoring (SHM) based on Lamb waves, a type of ultrasonic guided waves, is a promising method for in-service inspection of composite structures. Lamb waves can be excited and received using a network of actuators and sensors, which are permanently attached to the structure. By analysing the sensor signals, different kinds of structural defects can be detected and located through the interaction of the Lamb waves. This paper presents the development and manufacturing of a full-scale composite fuselage panel with a

Presidents at thirty of the top United States airlines were asked to indicate what educational preparation they felt students seeking a career in airline management should possess. They were asked to rate 18 courses offered in the Aviation Management baccalaureate degree curriculum at Southern Illinois University at Carbondale. They were also asked to rank 14 suggested courses from the Council on Aviation Accreditation (CAA) Curriculum Guideline. Following analysis, courses were placed in three categories: Inclusionary, Exclusionary and Uncertain/Diverse.Findings indicate that airline presidents place the greatest value on courses stressing fiscal requirements, legal aspects, airline operations and operating in a global environment.

Crew Resource Management as an academic field of study has only been in existeice for a relatively short period.However, because of its importance to the aviation community and the airlines in particular, there is a small but growing community of researcher and academicians that are specializing in its postulates. Despite the importance of research to the aviation industry and to aviation education, no comprehensive compendium of point specific literature exists. This void presents an obstacle for both researchers and practitioners in locating articles that may be relevant to their work.In addition, because of a narrow scope of many aviation education programs, researchers seeking information are often unaware of specificity's that address the totality of any particular program. Thus, the authors set out to identify a particular point specific niche of articles relating to a particular time segment of the unfolding Crew Resource Management Training field. Using descriptive research methodology and a systematic and thorough computer methodolojp, three hundred eighty-five citations were identified. These then were culled of duplication and a resultant suzty-six representative articles, with abstracts were found to coincide to the period of 1993 to 1998. These were W e r refined to key topics of a) the current status of CRM training and research, b) evolution of CRM concepts, c) measuring methods, and d) application of CRM.The history of CRM, Crew Resource Management, or as originally titled, Cockpit Resource Management is relatively short by modern standards. Its history is almost as short as that of the Airline Deregulation Act, which occurred only one year prior to the commonly accepted beginnings of CRM. Most practitioners trace the early fonnation of CRM to a meeting held by the National Aeronautic and Space Admimtration entitled Resource Management on the Flightdeck (Cooper, White & Lauber, 1993).Since that time many meeting, papers, research and training activities have created a natural time metamorphosis to occur that has as its Genesis the evolutionary process of valuable research and natural changes occurring with input. So pervasive has this metamorphosis become that Heherich, Ashleigh and Wilhelm (1998) have defined an evolutionary period corresponding to five generations, each have an identified event corresponding to their introduction.This natural change period has the most recent generation, the Bth, m its formative stages and is identified as the period of a search for a universal rationale. Underlying this fifth generation of CRM is the premise that human error is ubiquitous and inevitable, providing a valuable source of information (p.5). The aim of this fifth generation is the normalization of error and the development of strategies for managing error (Heherich, 1997).The fourth generation, the most complete, has been c h a r a c t d by the requkment of major air carriers to make detailed analysis of training requirement for each type of aircraft in their fleets along with the development of p...

Due to industrial automation of liquid composite molding processes and increasing geometrical complexity of composite components, dry-spots from flow front junctions have become increasingly difficult to avoid. The impact and behavior of voids (microscopic or small macroscopic gas entrapments) during preform impregnation is well known, but no attention is given to dry-spots (large macroscopic gas entrapments). Experiments show that formation of a dry-spot in an early stage of an injection process does not necessarily lead to scrap parts. Therefore, simulation-based predictions of dry-spots are no sufficient condition for identification of unsuitable injection strategies. In this paper, the resolution mechanisms of dry-spots under controlled process conditions are investigated and the resulting findings of fundamental formation-and dispersion-mechanisms are presented.
