11 - Operations and SustainmentFUEL-BURN PENALTIES CAUSED BY IRREGULARITIES IN AIRCRAFT SURFACES (ASTEROID PROJECT)D. Philpottš, K. Hackettš, A. Shires˛, B. Hinchliffe˛; šIHS Markit (ESDU), United Kingdom ;˛University of Leeds, United Kingdom ASTEROID aids economic decisions on manufacturing/servicing tolerances and repair strategies with easy-to-use tools for the estimation of aerodynamic drag and fuel-burn penalties caused by repair patches poorly rigged control surfaces etc. Current estimation procedures, their proposed development and user interfaces are described. |
