개요

BlendedNet은 999개의 blended wing body (BWB) 기하학적 형상에 대한 공개적으로 이용 가능한 공기역학 데이터셋입니다. 각 형상은 약 9가지의 비행 조건에서 시뮬레이션되어 Spalart-Allmaras 모델과 각 케이스당 900만에서 1400만 개의 셀을 사용한 8830개의 수렴된 RANS 케이스를 생성합니다. 이 데이터셋은 기하학적 설계 매개변수와 비행 조건을 샘플링하여 생성되며, 양력과 항력 연구에 필요한 상세한 점별 표면 데이터를 포함합니다. 또한 점별 공기역학 예측을 위한 엔드투엔드 서로게이트 프레임워크를 소개합니다. 이 파이프라인은 먼저 순열 불변 PointNet 회귀 모델을 사용하여 샘플링된 표면 포인트 클라우드로부터 기하학적 매개변수를 예측한 다음, 예측된 매개변수와 비행 조건에 대해 Feature-wise Linear Modulation (FiLM) 네트워크를 조건화하여 점별 계수 Cp, Cfx 및 Cfz를 예측합니다. 실험 결과 다양한 BWB에 대한 표면 예측에서 낮은 오차를 보여줍니다. BlendedNet은 비전통적인 구성에 대한 데이터 부족 문제를 해결하고 공기역학 설계를 위한 데이터 기반 서로게이트 모델링 연구를 가능하게 합니다.
