Freestream and captive potential, euler and navier-stokes simulations of the AGM-84 and GBU-24 on the F/A-18C

摘要

During any stores clearance program the structural adequacy of the airframe to carry the store through-out the flight envellope must be certified, requiring accurate predictions of store carriage loads. This paper presents a comparison of results between linear potential, full potential, Euler and Navier-Stokes computations of the AGM-84 HARPOON and the GBU-24 PAVEWAY III weapons and available wind tunnel results. The stores' aerodynamics were simulated in both freestream flow and in the presence of a tailless F/A-18C aircraft with wing pylons and an adjacent pylon mounted 330 gallon fuel tank.
