3. Aircraft DB
Lift and drag configuration of the generic body and wing is more opened to public [1, 2]; also I had summarized lift and drag information related to generic airliner configuration. (3. Summary CFD Workshop : 3.1.1) High fidelity data is available while generic equation is used to make single-aisle airliner aerodynamic DB.

1) Lift - Simple formula for Wing and Fuselage
Lift of the main wing and body can easily be estimated by the formula and specification
Lift of the main wing and body can easily be estimated by the formula and specification
2) Drag - Simple formula for Wing and Fuselage
Drag of the main wing and body is more complex than the lift. Composition of the drag component is shown below. Form factor(pressure), Skin-Friction, Interference, and Wave drag are added or multiplied to provide the estimated value.
3) Comparison - Reference Vs Formula
Because formula based generic body is not same body of the reference, there will be a difference. However, I could expect similar trend between the generic one and result from the reference. Both aircraft did not take account the tail or other effect.
