“…On the other hand, continuous advances in NLF have substantially increased the knowledge and understanding of the mechanism of NLF applied to aircraft analysis and design. Multiple high-speed aircraft configurations with significant assessments of NLF have been proposed by various researchers [13,14], and methods that help integrate the technology [15,16] have recently been proposed. Operating uncertainties regarding the instability of the NLF during the flight [17] and effects of contamination on the flight mission [18] were also assessed to strengthen the understanding of NLF technology implementation for large aircraft.…”

The present research investigates the potential application of the natural laminar flow wing technology to business jet market segments from light to long-range jets. A database of existing business jets was generated to determine the range extension as a potential driver of customer interest. A conceptual design of several configurations for each market segment was performed to investigate potential improvements in the aircraft flight range, operating costs, and price changes using the technology. An initial sizing module and a low-fidelity multidisciplinary design optimization were used to size all aircraft. Results demonstrated a 13–30% increase in the flight range depending on the aircraft concept. Long-range jets with natural laminar flow could not achieve significant range extension due to a combination of the design airspeed and maintenance costs. A rapid increase in acquisition prices for all aircraft suggested that super-midsize and large jets that combine relatively low empty weight and high range extension could be more favorable options compared to other segments, but a significant reduction of acquisition costs and an increase in operating flight hours are required to make the technology implementation successful.
