The integrity of takeoff and landing areas is also an issue; floating logs and other debris are a major hazard. 100%. More commonly, support for commercial supersonic aircraft is based on other important factors: their ability to provide better service (by reducing travel time), the national economic benefits from being first to market with a commercially successful supersonic aircraft, and the economic damage from a foreign aerospace company being first to market. 75. The use of e-commerce also allows suppliers to track part usage and to identify customers in need of reordering. Nanotechnology may lead to the development of new structural materials with high strength-to-weight ratios and fracture toughness, durable coatings, greater resistance to corrosion, self-healing, and multifunctional characteristics. When preproduction of the next-generation Tempest fighter jet ramps up next year, assemblers at BAE Systems will be using cutting-edge technology. Washington, D.C.: National Academy Press. Aircraft Noise In 2002, Boeing began implementing lean principles at its 737 Wichita, Kan. manufacturing plants, with big payoffs. However, further ents of the tube -and wing configuration powered Air travel in the United States has seen dramatic improvements in safety in the past 50 years. Advances in aircraft development, including the ecological inclusion of better fuel efficiency, recyclability concerns and more, mean that all involved, from manufacturers to suppliers, must become early adopters of useful technology to flourish. In aviation, the Brayton cycle has historically been the cycle of choice when the effects of propulsion system weight, volume, and durability are factored into the entire aircraft and air transportation system. Nanotechnology can support distributed sensing: adhesive tape with embedded sensors has been developed that can be used on vehicles during flight tests. The properties that nanomaterials demonstrate at nanoscales do not necessarily predict the properties of macroscale materials that incorporate nanomaterials. 2002b. The goal is to reduce noise below objectionable levels even as traffic increases. The National Science Foundation recently completed a solicitation for research in this area. Technologies specifically related to personal air vehicles, UAVs, supersonic aircraft, or runway-independent air vehicles do have the potential to improve the performance of the air transportation system, especially in niche areas. Click here to buy this book in print or download it as a free PDF, if available. This changes chemical reactivity, coherent scattering, and other processes. The joined wing configuration is similar in concept to a biplane whose lower wing has positive dihedral (the tip of the wing is higher than the point of attachment to the aircraft centerbody) and is swept back from where it is attached to the fuselage. NRC. Composite materials with improved qualities that would increase their use in airplane structures and reduce aircraft weight. Recommendation 4-1. Runway-independent air vehicles may be able to help meet increased demand at capacity-limited airports, and in any case they execute unique, important missions that other types of aircraft cannot perform. FIGURE 4-4 Predictions made in 1968 of subsonic thrust-specific fuel consumption, updated with data on operational systems developed since 1968. Even so, tremendous advances in the power density of fuel cells would be required to make them technologically feasible as a source of propulsion power for large commercial aircraft. These measures are intended to increase incentives to improve fuel efficiency. Safran’s products on board aircraft and helicopters. Avionic systems include computers, communications networks, sensors, controls, operational software, and human-computer interfaces. The federal government, especially the Department of Defense, has supported basic long-term research and applied research and technology development that continue to enhance the capabilities of avionics on both civil and military aircraft. For airlines, operational cost (i.e., cost per seat-mile) is a key measure of aircraft performance. However, these reductions have been largely offset by higher engine pressure ratios (for improved fuel efficiency), which tend to increase emissions of NOx and particulate matter. During World War I, the requirements of higher speed, higher altitude, and greater maneuverability drive dramatic improvements in aerodynamics, structures, and control and propulsion system design. Finally, while less of a technology and more of a philosophy, the principles of lean manufacturing have played a huge role in revolutionizing the efficiency of all areas of the aviation industry. Concepts such as BWB aircraft, supersonic business jets, and runway-independent aircraft dictate unique requirements and opportunities for advances in propulsion technology. Throughout the years, technology improvements have been made to aircraft and engines to make them more fuel efficient. Also, you can type in a page number and press Enter to go directly to that page in the book. Just as we’ve seen in the automotive industry, there will likely be intermediate “hybrid” propulsion systems brought to market until the technology matures. Additional airframe research and technology development are needed to improve the performance of aircraft, particularly with regard to the feasibility of nontraditional subsonic transport concepts. rently available information indicates that propulsion research should generally support the continued evolution and use of high-bypass turbofan engines burning liquid hydrocarbon fuels. Similarly, a research program to improve the performance of commercial aircraft could be structured with several parallel tracks to cover short-term, medium-term, and long-term goals.
