FoilSim 3

 The Airfoil View Panel 是一个模拟机翼在风洞与空气测试，它正在从左至右使学生变了通过移动滑块控件不同的空速，高度，迎角，厚角和曲率的翼型，机翼面积和大小的参数的机翼位置和形状。
FoilSim 3显示压力情节或空速机翼上方和下方的表面。一个监视探头在一个特定的点上或接近地面空气的翼型条件（速度和压力）。该软件计算了机翼升力，使学生学习的因素，影响电梯。该软件包括一个用于翼型失速模型和比较的升降机火星大气模型。

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.
