As you may know, there is a NACA 0012 model in application library which tries to validate the lift coefficient and pressure coefficient (with respect to angle of attack) against existing data in the literature. The lift force is obtained by integrating either of the following equations over th...

If you change the components of the velocity (and don't rotate the geometry), the lift and drag direction must change. If you rotate the geometry, the lift and drag direction don't change. For exemple, if you change your flow direction (angle of attack) like this : ...
For a given flight condition, which of the following parameters are related to the longitudinal static stability? A、机翼弯度 Wing camber B、平尾尾容比 Tail volume ratio C、重心位置 CG location D、飞机升力系数 Lift coefficient E、下洗角 Downwash angle F、平尾动压比 Tail dynamic pressure ratio...
The working conditions are Re = 1E6, Ma = 0.2, and angle of attack (AOA) = 1°. The aerodynamic forces are computed by XFOIL. 2190 airfoils are randomly divided into two parts: 1978 airfoils for training and 212 for testing. The second case is a high Mach number 2D airfoil data set...
In general, extending large angle flaps increases lift and drag coefficient, decreases critical angle of attack, and ___ the ratio of lift and drag.A.increasesB.does not changeC.decreasesD.is hard to determine whether increasing or decreasing的答案是
The aerodynamic coefficients CL, CD, and CT are specified by the velocity ratio α=u/V and not by the angle of attack, as specified for wings. The aerodynamic forces are calculated as usual (4, 5). The aerodynamic moment is defined in Eq. (6) according to Thom [17]. This equation ...
