Integration design and analysis for curved conical forebody and threedimensional inward turning inlet

By analyzing the aerodynamic characteristics of different angles of attack on conical flow field, and based on the streamlines traced concept, an integrated designed methodology for curved conical forebody and threedimensional inward turning inlet was proposed; besides, the effects of three outline and position parameters on the integrated configuration were theoretically investigated. It was discovered that the effect of the expansion angle of side wall on the inlet mass flow rate coefficient was remarkable, while the effect of the central angle on inlet was mainly reflected on geometric features. Furthermore, the mass flow rate coefficient of the inlet demonstrated a negative correlation with the external compression surface length. Based on the investigation of the flow capture shape, an integrated configuration of the curved conical forebody and threedimensional inward turning inlet was then designed and studied numerically. The results show that, at the design point (incoming Mach number is 60), the mass flow rate coefficient of the inward turning inlet is 093, and the total pressure recovery coefficient is 061. In addition, at offdesign point (incoming Mach number is 50), the mass flow rate coefficient and the total pressure recovery coefficient are 086 and 077, respectively.
