The design of air intake systems for modern fifth generation fighter aircraft is of great significance as it directly affects the stealth characteristics of the aircraft. The major sources of Radar Cross Section (RCS) in an aircraft are its cavities such as air intake, diverter passage, weapon bays, etc. A diverterless air intake provides two fold advantages in supersonic military aircraft. In comparison with traditional intake with boundary layer diverter, a diverterless intake offers better aerodynamic performance at high speeds. It also gets rid of the diverter passage and the bump ahead of the entry to the intake provides additional shielding to the incident radar waves, thereby reduces RCS of the aircraft. It also eliminates the need to have moving surfaces used for efficient compression at high supersonic speeds. This paper presents the design approach of a Diverterless Supersonic Intake (DSI) on a generic stealth fighter aircraft and performance comparison with a conventional intake with boundary layer diverter.
