To satisfy the demand of combined circle engine, design and aerodynamic performance analysis of an axisymmetric variable geometry inlet was carried out. First, an axisymmetric fixed geometry inlet was designed based on a design condition and analyzed at different Mach number. Second, a variable scheme was designed to satisfy the demand of mass flow rate and ensure the inlet start under different Mach number, and an adjustment method was given out at the end. Finally, the annular to circle diffuser was studied to achieve better aerodynamic performance.
