摘要： The present invention discloses an internal-parallel inlet with mode conversion combined with variable geometry adjustment, which comprises a high-speed channel, a low-speed channel, a mode conversion component, a variable geometry component and a motor actuating component. When the inlet is in a low-speed mode, the variable geometry component adjusts the throat area and the internal contraction ratio of the inlet. When the flight Mach number is in a range of the mode conversion Mach number, the mode conversion component and the variable geometry component work simultaneously. When the inlet is in a high-speed mode, the mode conversion component is combined with the variable geometry component to adjust the throat area and the internal contraction ratio of the inlet. The present invention also provides a method for controlling the inlet.
