As part of the UK Research and Innovation project New Aviation, Propulsion, Knowledge and Innovation Network (NAPKIN), a high-level framework was developed for the assessment of the noise impact of the proposed regional-sized hydrogen-powered aircraft. This study consists of the methodology used to generate the industry-standard noise–power–distance (NPD) curves from individual component noise analysis, specifically propeller tonal noise. The model is based on an asymptotic analysis of a frequency domain propeller tonal noise model combined with a linear approximation, taking advantage of the logarithmic nature of noise. An error analysis on the linear approximation assumption proves that the relative error between predicted and actual values of the noise remains below 10% for appropriately chosen baseline points. Verification of the framework was achieved through a bench-marking procedure that compared predictions of departure NPD curves for current technology regional aircraft against published ones over a range of operational power settings. Finally, departure and approach NPD predictions for three of the NAPKIN hydrogen concept aircraft are presented. Concepts featuring a larger, slower-rotating propeller with an increased number of blades relative to the reference aircraft showed benefits over the reference aircraft, despite, in some cases, increases in maximum takeoff weight.

The vortex particle method (VPM) has gained popularity in recent years due to a growing need to predict complex aerodynamic interactions during the preliminary design of electric multirotor aircraft. However, VPM is known to be numerically unstable when vortical structures break down close to the turbulent regime. In recent work, the VPM has been reformulated as a large-eddy simulation (LES) in a scheme that is both meshless and numerically stable without increasing its computational cost. In this study, we build upon this meshless LES scheme to create a solver for interactional aerodynamics. Propeller blades are introduced through an actuator line model following well-established practices for LES. A novel, vorticity-based actuator surface model (ASM) is developed for wings, which is suitable for propeller–wing interactions when a wake impinges on the surface of a wing. This ASM imposes the no-flow-through condition at the airfoil centerline by calculating the circulation that meets this condition and by immersing the associated vorticity in the LES following a pressure-like distribution. Extensive validation of propeller–wing interactions is presented by simulating a tailplane with tip-mounted propellers and a blown wing with propellers mounted midspan.
近年来，由于在电动多旋翼飞行器的初步设计过程中越来越需要预测复杂的气动相互作用，涡旋粒子法（VPM）越来越受欢迎。然而，众所周知，当涡旋结构在接近湍流状态时破裂，VPM 在数值上会不稳定。在最近的工作中，VPM 已被重新表述为一种大涡流模拟（LES）方案，该方案既无网格又具有数值稳定性，同时还不会增加计算成本。在本研究中，我们以这种无网格 LES 方案为基础，创建了交互式空气动力学求解器。螺旋桨叶片是通过执行器线模型引入的，该模型采用了成熟的 LES 方法。为机翼开发了一种新颖的、基于涡度的致动器表面模型（ASM），该模型适用于螺旋桨与机翼之间的相互作用（当尾流撞击机翼表面时）。该 ASM 通过计算满足该条件的环流，并将相关涡度按照压力分布浸入 LES 中，从而在机翼中心线上实现无穿流条件。通过模拟带尖端安装螺旋桨的尾翼和带中跨安装螺旋桨的吹翼，对螺旋桨与机翼的相互作用进行了广泛验证。
