| Abstract: | In this paper,Transonic doublet lattice method(TDLM) is improved,and the flutter velocity can be calculated automatically,the computing time is reduced considerably.These improvements are also beneficial to the application of the TDLM at large Mach numbers and reduced frequency.The unsteady aerodynamic results of the transonic wing are presented,and flutter calculation is made.The comparison with TDLM shows that the agreement is very good. |
