Aeronautical Engineering Technology (AET) of Purdue University’s School of Aviation and Transportation Technology offers its students a comprehensive and holistic approach to engineering in an applied fashion. Students’ learning outcome includes an application of technical knowledge and hands-on skills in areas of aerospace design, operations, and manufacturing. The curriculum of the program includes a course in which students must learn advanced maintenance concepts and practices including the overhaul of reciprocating engines. This study examined the relationship between engine operational vs. non-operational statuses, time spent to finish a task, and student perceived workloads regarding the maintenance procedures. The tests followed the Federal Aviation Administration (FAA) requirements for the practical test questions from the Airframe and Powerplant Certificate (A&P) Exam. Students were also required to fill out a task perceived load index developed and used by NASA.

Industry-centered education has been an integral part of the educational program at Maine Maritime Academy (MMA) since the founding of the college in 1941. This has included extensive use of laboratories and cooperative education as part of all MMA academic programs. Employers, graduates, and potential students describe MMA’s “hands-on” focus, reflected in the laboratory and cooperative education experiences, to be one of the main advantages of an MMA education, including the Power Engineering Technology (PET) program. In 1993, the MMA Engineering Department decided to build on this strength for the PET program by adding a personal computer-based, power plant control room simulator laboratory. The simulators were integrated into the PET Capstone experience, a two-course, nine credit hour sequence, that included both individual and team projects. The simulators were used to provide additional realistic, “hands–on” training as the students completed their degree. Over the course of the past fifteen years, while the simulators have continued to be a valued tool for the PET Program, the simulators were reaching the end point of their viable use due to hardware obsolescence. Since the simulator software was hardware specific, it had become impossible to procure replacement hardware for the simulators. In 2008, it was decided to replace the simulators and new simulator hardware and software have been procured and will be integrated into the PET Program beginning in the fall 2010 semester. This paper will describe the process used to determine the scope of the replacement process, the parameters for the new simulation systems, the procedure for determining the systems selected, and the process of integrating these new resources, including the assessment methods using the simulators, into the PET Program.

The Relationship

Modern Earth Scientists need also to interact with other disciplines, apparently far from the Earth Sciences and Engineering. Disciplines related to history and philosophy of science are emblematic from this perspective. From one side, the quantitative analysis of information extracted from historical records (documents, maps, paintings, etc.) represents an exciting research topic, requiring a truly holistic approach. On the other side, epistemological and philosophy of science considerations on the relationship between geoscience and society in history are of fundamental importance for understanding past, present and future geosphere-anthroposphere interlinked dynamics.

The Relationship

Exposing students to hands-on experiments has been a common approach to illustrating complex physical phenomena that have been otherwise modelled solely mathematically. Compressible, isentropic flow in a duct is an example of such a phenomenon, and it is often demonstrated via a de Laval nozzle experiment. We have improved an existing converging/diverging nozzle experiment so that students can modify the location of the normal shock that develops in the diverging portion to better understand the relationship between the shock and the pressure. We have also improved the data acquisition system for this experiment and explained how visualisation of the standing shock is now possible. The results of the updated system demonstrate that the accuracy of the isentropic flow characteristics has not been lost. Through pre- and post-laboratory quizzes, we show the impact on student learning as well.

This paper shows the finite element simulation of a representative specimen from the firewall section in the AEROMARMI ESTELA M1 aircraft. This specimen is manufactured in glass and carbon / epoxy laminates. The specimen is subjected to a load which direction and magnitude are determined by a previous dynamic loads study [10], taking into account the maximum load factor allowed by the FAA (Federal Aviation Administration) for utilitarian aircrafts [11]. A representative specimen is manufactured with the same features of the firewall. Meanwhile a fix is built in order to introduce the load directions on the representative specimen. The relationship between load and displacement is plotted for this representative specimen, whence the maximum displacement at the specific load is obtained, afterwards it is compared with the finite element model, which is modified in its laminate thicknesses in order to decrease the deviation error; subsequently this features could be applied to perform the whole firewall analysis in a future model [10].
