Aerodynamic Performance Computation Analysis of the Subscale UCAV for Training
摘要
Abstract
In order to decrease the maintenance and flight training cost of UCAV,a subscale model for training with the same flight performance and controlling characteristic as full scale prototype vehicle ass developed referring to the flight test of subscale model during the process of aircraft design. According to similar parameters analysis with the similarity theory,the flight alitude of subscale model was compared to the full scale prototype vehicle.The geometry of the subscale model was imported to Gridgen soft to build the flow field around the model with unstructured grid.The longitudinal aero?dynamic performances of the subscale model were computed by Fluent soft.The position of aerodynamic center was esti?mated with pitch moment coefficient data.It prepares for the further work at controllability/stability investigation and con?trol law design.关键词
