A novel embedded type air inlet channel comprises an air inlet (1), an air outlet (2), a side edge (3), an inner channel (4), a low-energy flow discharge port (5), a low-energy flow discharge channel (6), a front flow guide face (7), a rear flow guide face (8) and a vortex low-energy flow guider (9), the vortex low-energy flow guider (9) is arranged on the front flow guide face (7), the inner channel (4) is arranged behind the vortex low-energy flow guider (9), and the side edge (3) is arranged in the inner channel (4). The low-energy-flow discharging ports (5) are symmetrically formed in the two sides of the inner channel (4) and communicated with the low-energy-flow discharging channel (6), and the rear flow guiding face (8) is arranged behind the inner channel (4). According to the embedded type air inlet channel, boundary layer low-energy flow flowing into the embedded type air inlet channel is effectively reduced, the quality of airflow entrained into the embedded type air inlet channel is improved, and therefore the total pressure recovery coefficient of the embedded type air inlet channel is increased, and the outlet distortion index is reduced.
一种新型埋入式进气道,包括进气口(1)、出气口(2)、侧棱(3)、内通道(4)、低能流放泄口(5)、低能流放泄通道(6)、前导流面(7)、后导流面(8)及旋涡低能流导向器(9),其中,前导流面(7)上设置有旋涡低能流导向器(9),旋涡低能流导向器(9)后方设置有内通道(4),内通道(4)两侧对称设置有低能流放泄口(5),低能流放泄口(5)与低能流放泄通道(6)连通,后导流面(8)设置在内通道(4)后方。本发明有效减少流入埋入式进气道的边界层低能流,改善卷吸入埋入式进气道的气流品质,从而提高埋入式进气道的总压恢复系数,降低出口畸变指数。
