Hypersonic Inlet/Isolator

Superior disturbance resistance

With an external compression angle, this inlet/isolator maintains uniform outlet flow and exhibits significantly reduced variations in total pressure recovery coefficient under varying incoming boundary layer thicknesses, providing stable conditions for downstream combustion.

Advantages

At 10° compression angle, variations in total pressure recovery coefficient are smaller under different boundary layer thicknesses

Outlet flow field of isolator is more uniform
