2.3. Individual Technologies As can be seen from Table 2, the main contributions to fuel efficiency in evolutionary aircraft design are in the areas of aerodynamics, new engine architecture and systems. Aerodynamics Aerodynamic technology has been progressing continuously throughout the past decades to produce new designs with significantly reduced drag. An aerodynamic technology that has been pursued over many years and has recently made new progress in development is Laminar Flow Control. This technology allows considerable drag reduction by preventing turbulences in the airflow over the surface of the aircraft. Natural Laminar Flow (NLF) Control achieves laminar flow only by designing the surfaces of the wings and other aircraft parts with a suitable shape. This technology is studied for example in the project BLADE (Breakthrough Laminar Aircraft Demonstrator in Europe). Since September 2017, flight tests have been conducted with an A340 test aircraft, on which the outer wing sections, of about 10 meters width, were replaced by laminar profiles. The size of the laminar sections is representative for the wing dimensions of typical narrow-body aircraft, which are likely to apply the laminar flow technology first. From the test flight results, the fuel saving potential of NLF for an 800-nautical mile flight would be around 4.6% [27]. Another way to create laminar flow conditions is Hybrid Laminar Flow Control (HLFC), which uses boundary-layer suction to maintain laminar flow over the aircraft surface. This technology is particularly suited for swept wings and 18 fins. NASA, in the framework of its Environmentally Responsible Aviation (ERA) research program, carried out a series of test flights on a B757 equipped with a HLFC system to evaluate the dependence of laminar conditions on factors such as surface manufacturing, suction devices and surface coatings to prevent contamination [28]. Figure 7: A340 Laminar Flow BLADE demonstrator first flight New Engine Architecture In recent and imminent new aircraft models, the most significant contribution to fuel burn reduction comes from new engine technologies. Some of these engines have already entered service and others are expected to be installed on new aircraft in the near future. These engines have higher by-pass-ratios (BPRs) than previous engine models. In the case of regional jets and single-aisle aircraft such as the MRJ, the Embraer E2 family, A220 (formerly C series), A320neo and 737MAX, new engines operating on these aircraft have a BPR of 9 to 12, which allow fuel burn Figure 6: The NASA TRL Meter [23]PDF Image | Aircraft Technology Roadmap to 2050
