The invention relates to a detonation engine, in particular to a double-lower-side rear-mounted supersonic air intake channel. The double-lower-side rear-mounted supersonic air intake channel is used for overcoming the defects that detonation waves generated by a ramjet detonation engine cause the air intake channel not to be started, and the working performance of a combustion chamber is affected. The double-lower-side rear-mounted supersonic air intake channel comprises air intake channel compression cones, a boundary layer isolation device, transition sections and annular switching sections connected with an annular combustion chamber. The air intake channel is arranged at the rear, so that a large amount of effective space of an aircraft front body is saved, the air intake channel performance of an aircraft in the positive attack angle state can be improved by symmetrically distributing the air intake channel compression cones at 60 degrees-180 degrees, and the engine performance is further improved.

    本发明涉及爆震发动机,具体涉及一种双下侧后置超声速进气道,用于解决冲压爆震发动机产生的爆震波导致进气道不起动,以及影响燃烧室工作性能的不足之处。该双下侧后置超声速进气道包括进气道压缩锥、附面层隔离装置、过渡段,以及与环形燃烧室连接的环形转接段。本发明通过将进气道后置,节省飞行器前体大量的有效空间,并且进气道压缩锥呈60°~180°对称分布可以提高飞行器在正攻角状态时进气道性能,进一步提高发动机性能。
