The low-sweep transonic natural laminar flow wing with shock control bumps, namely, LS-NLF-SCB wing, has a promising potential to be applied to future narrow-body commercial aircraft due to its advanced natural laminar wing design combined with shock control. This paper aims to assess the benefits of LS-NLF-SCB wing application from the viewpoint at the aircraft level. Based on the previous published results, it is assumed for analysis that the 20° sweep LS-NLF-SCB wing has a significant portion of laminar flow on both the upper and lower wing surfaces and that the wave drag level is maintained. The benefits of the LS-NLF-SCB wing application on commercial aircraft are assessed by comparisons between a typical narrow-body commercial configuration with baseline wing and a configuration with LS-NLF-SCB wing, from analysis of aerodynamics, weights, field performance, emissions, and cost. The assessment results indicate that the improvement of the LS-NLF-SCB aircraft can be shown in a number of areas, including an 11.1% reduction of fuel consumption, a 3.1% decrease of maximum takeoff weight, and a 3.4% reduction of direct operating cost.

具有减震凸点的低掠跨音速自然层流机翼，即LS-NLF-SCB机翼，由于其先进的自然层流机翼设计与减震控制相结合，具有潜在的潜力可用于未来的窄体商用飞机。本文旨在从飞机层面评估LS-NLF-SCB机翼应用的益处。根据先前发布的结果，分析时可假定20°掠角LS-NLF-SCB机翼在上，下机翼表面上都有很大一部分层流，并且波阻力水平得以保持。LS-NLF-SCB机翼在商用飞机上的应用优势，是通过对典型的窄体商用机构和基线机翼与LS-NLF-SCB机翼构架之间的比较进行评估的，其中包括对空气动力学，重量，现场性能，排放量和成本。评估结果表明，LS-NLF-SCB飞机的改进可以体现在许多领域，包括燃油消耗减少11.1％，最大起飞重量减少3.1％和直接运行减少3.4％。成本。
