Details of the NASA sponsored General Electric Energy Efficient Engine (E3) technology program are presented along with a description of the engine, cycle and aircraft system benefits. Opportunities for further performance improvement beyond E3 are examined. Studies leading to the selection of the E3 cycle and configuration are summarized. The advanced technology features, cycle and component performance levels are also presented. An evaluation of the benefits of the fully developed Flight Propulsion System (FPS) is made relative to the NASA program goals by comparing the FPS with the CF6-50C where both are installed in advanced subsonic transport aircraft. Results indicate that a mission fuel saving from 15 to 23 percent is possible depending on mission length.

The Garrett GTCP36-300 Series Auxiliary Power Unit is being developed for use on advanced technology transport aircraft in the 150-passenger size class. The first application will be the Airbus Industries A320 Aircraft. The APU uses a 6:1 pressure ratio, single-stage compressor and turbine, driving a single-stage load compressor and accessory gearbox. The 480 horsepower APU delivers compressed air to the aircraft pneumatic system and drives a customer furnished 90 kva, 24,000 rpm electrical generator. State-of-the-art aerodynamics, materials, and digital electronics are used to give the user-airlines an APU delivering maximum performance with minimum envelope, weight, and cost of ownership.

Based on airline pilot surveys, industry committees and workshops, conducted on advanced technology “glass cockpit” airplanes, concerns have been raised about the application and long-term effects of automation technologies. It has been pointed out that purely technology-driven designs had resulted in unintended and unforeseen negative consequences. In order to counter this trend it has been proposed to shift the focus from technology-centered designs to what has become known as human-centered design. There are three primary objectives within a human-centered design philosophy: (1) the design should enhance the user's abilities, (2) the design should help overcome user limitations, and (3) the design should foster user acceptance. This paper discusses the human-centered design objectives within the context of commercial transport airplane developments. Representative examples of a human-centered design are presented.

A fixed-base simulator study has been conducted to evaluate the effects of varying several parameters of a cathode ray tube (CRT) presentation of an advanced display for instrument landing of transport aircraft. This research was conducted in support of NASA's Terminal Configured Vehicle (TCV) program which was established to develop and evaluate advanced aircraft systems that will benefit conventional takeoff and landing operation in the terminal area.

The Government

The increasing cost of weapons provided the stimulus needed for the Navy and Air Force jointly to study common engine requirements for the 1990s. Since engines require several years longer to develop than airframes, the Government sponsored the Advanced Technology Engine Study (ATES) to develop a long range propulsion plan for new aircraft needed through 2010. Because of the interaction between aircraft and engine in the design of the weapon system, aircraft engine companies teamed with aircraft companies to provide aircraft and engine conceptual designs to perform the expected missions for the 1990 time period. Life Cycle Cost (LCC) was used as the criterion in evaluating the merit of a number of USN and USAF aircraft systems. Since operating and support costs (0&S) are the most difficult of LCC to predict accurately, this paper compares only development and production costs provided by the participating contractors with those costs determined using cost criteria developed by the Navy.

Purpose The use of real-time recording technology for clinical instruction allows student clinicians to more easily collect data, self-reflect, and move toward independence as supervisors continue to provide continuation of supportive methods. This article discusses how the use of high-definition real-time recording, Bluetooth technology, and embedded annotation may enhance the supervisory process. It also reports results of graduate students' perception of the benefits and satisfaction with the types of technology used. Method Survey data were collected from graduate students about their use and perceived benefits of advanced technology to support supervision during their 1st clinical experience. Results Survey results indicate that students found the use of their video recordings useful for self-evaluation, data collection, and therapy preparation. The students also perceived an increase in self-confidence through the use of the Bluetooth headsets as their supervisors could provide guidance and encouragement without interrupting the flow of their therapy sessions by entering the room to redirect them. Conclusions The use of video recording technology can provide opportunities for students to review: videos of prospective clients they will be treating, their treatment videos for self-assessment purposes, and for additional data collection. Bluetooth technology provides immediate communication between the clinical educator and the student. Students reported that the result of that communication can improve their self-confidence, perceived performance, and subsequent shift toward independence.
