AVL
AVL是MIT(麻省理工)用fortran开发的一个气动和飞行动力学分析程序。
下面是它的一个官方说明:
AVL is a program for the aerodynamic and flight-dynamic analysis of rigid aircraft of arbitrary configuration. It employs an extended vortex lattice model for the lifting surfaces, together with a slender-body model for fuselages and nacelles. General nonlinear flight states can be specified. The flight dynamic analysis combines a full linearization of the aerodynamic model about any flight state, together with specified mass properties.

非定常流动
AVL对于非定常流动都假定为准定常流动,这意味着计算时忽略了非定常脱落涡流。而且,AVL还将飞机状态限定在一定的缩减频率范围内,如,无量纲的旋转角速度一般做如下限制:
-0.10 < pb/2V < 0.10
-0.03 < qc/2V < 0.03
-0.25 < rb/2V < 0.25
