Aerodynamic Characteristic Analysis And The Stealth Characteristics Analysis Of E-2C Hawkeye

The test flight of J-15carrier-based fighter was successful in China, and the "Liaoning" aircraftcarrier has been commissioned. With the increasing demand for maritime operations, early-warningaircrafts play an irreplaceable role in the warfare. It’s a major trend that China has its ownchinese-made airborne early-warning aircraft.The research object of this paper is E-2C, an airborne early-warning aircraft. The work of this papercontains three parts about the research object: three-dimensional configuration reconstruction,computation and analysis of aerodynamic characteristics, estimation and analysis of3D solidconfiguration reproduction, aerodynamic characteristics analysis and flight performance analysis. Thispaper reconstructed an accurate3D configuration of E-2C, with the theory of3D solid configurationreproduction from respective images. With the3D configuration and the CFD theory, this papercomputed and made an analysis on the aerodynamic characteristics of the E-2C. After that, in thesame condition, this paper made a comparative analysis of the impact on the aerodynamiccharacteristics of the radome. The performance of climbing and the performance of taking off of theE-2C was computed by estimation method with the outcome of the aerodynamic characteristics. Atthe last chapter of this paper was the stealth characteristics analysis of the E-2C.
