A Modification to the Enhanced Correction Factor Technique for the Subsonic Wing–Body Interference Model

In this work, the enhanced correction factor technique (ECFT) is modified for a subsonic wing–body interference model, which can consider forces on both lifting boxes and body elements of an idealized airplane, termed advanced ECFT method. A passenger aircraft model chosen as simulation longitudinal static aeroelasticity at transonic situation two-degree freedom, including α (angle attack) degree ϕ horizontal tail) degree, simulated in paper. The corresponding CFD results are used to correct aerodynamic influence coefficients (AIC) matrix, then by MSC.NASTRAN. pressure distribution different components received method indicate that it suitable model. Compared with uncorrected linear diagonal corrected method, generally more consistent CFD/CSD coupling not only boxes, but also elements. addition, derivative show good agreement flight test data, solidly verifies advance
