FoilSim 3

 The Airfoil View Panel 是一個模擬機翼在風洞與空氣測試，它正在從左至右使學生變了通過移動滑塊控件不同的空速，高度，迎角，厚角和曲率的翼型，機翼面積和大小的參數的機翼位置和形狀。
FoilSim 3顯示壓力情節(jié)或空速機翼上方和下方的表面。一個監(jiān)視探頭在一個特定的點上或接近地面空氣的翼型條件（速度和壓力）。該軟件計算了機翼升力，使學生學習的因素，影響電梯。該軟件包括一個用于翼型失速模型和比較的升降機火星大氣模型。

The Airfoil View Panel is a simulated view of a wing being tested in a wind tunnel with air moving past it from left to right. Students change the position and shape of the wing by moving slider controls that vary the parameters of airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area. FoilSim 3 displays plots of pressure or airspeed above and below the airfoil surface. A probe monitors air conditions (speed and pressure) at a particular point on or close to the surface of the airfoil. The software calculates the lift of the airfoils, allowing students to learn the factors that influence lift. The software includes a stall model for the airfoil and a model of the Martian atmosphere for lift comparisons.
