A wind-tunnel testing of a streamline traced hypersonic Busemann inlet
with a designed Mach 5.3 and shrinkage ratio CR=5
was conducted at Mach 3.85 to study its starting and overall performance as well as back-pressure capability below Mach 5.3 conditions.The results show that
the inlet can be started automatically at Mach 3.85;the flow coefficient of inlet is 0.83
the overall pressure recovery coefficient is 0.78
with a Mach number 2.01 and a compression ratio of 11.92;the inlet can withstand a maximum back-pressure of 34 times static pressure.
