| Abstract: | Some modifications are conducted in engineering calculations for inlet design
such as two-dimensional oblique shock angle,total pressure recovery coefficient at
rounded lip,subsonic critical flow coefficient and minimum throat area,to be available to computerization.It is shown that, the calculation with modified method is procise enough to satisfy the needs of selecting and analysing parameters in inlet design, compared with experimental data. The modified method presented in this paper could be used in CAD of inlet. |
