Hello dear,
i want to model a wing sections (4sections) with external aerodynamics forces , in simescape multibody using five blocks such as Time, Atmosphore, gust, Mach Env; and ground; please i need help, Exemple : Screenshot of the SimMechanics wing model with eight nodes. thanks in advance

The question sounds too vague and general. It would be easier if you have specific question.
Also, looks like the figure is from the thesis of R.L.C. Kalthof, "Multibody Dynamics Modeling of Flexible Aircraft Flight Dynamics, Load Prediction in the Preliminary Design Phase". Maybe try contact the author for more information?

Hi Atef,
You can use the External Force and Torque block to apply a force to a frame in Simscape Multibody. The magnitude and orientation of that force can be calculated using Simscape, Simulink, MATLAB, or other languages. You can measure quantities from the Simscape Multibody model using the Transform Sensor block.
Here is a screenshot of a simple example to show you how the blocks are connected to model drag and lift within a plane.
