Dynamic Supersonic Base Store Ejection Simulation Using Beggar, Michael D. Johnson
Dynamic Supersonic Base Store Ejection Simulation Using Beggar, Michael D. Johnson
Theses and Dissertations
Static and dynamic conditions throughout various aft supersonic store separation events are examined using the Beggar Computational Fluid Dynamics (CFD) code from Air Force SEEK Eagle Office at Eglin Air Force Base, FL. An 8.9 deg half angle sphere cone is used for the carrier vehicle with an identically shaped store stowed within a hollow compartment in the aft section of the carrier body. Dynamic store separation simulations are implemented at a free-stream Mach of 2.9 with a Reynolds number of Re = 6.9 x 106/m referenced against carrier base diameter. Analysis covers multiple dynamic separation events along …
Handling Qualities Evaluation Of A Supersonic Tailless Air Vehicle, Steven W. Speares
Handling Qualities Evaluation Of A Supersonic Tailless Air Vehicle, Steven W. Speares
Theses and Dissertations
This thesis presents the results of a handling qualities evaluation of a supersonic tailless air vehicle. The 2006 Quadrennial Defense Review mandated the need for the next generation of long-range strike aircraft by 2018. Due to speed and stealth requirements, this resulted in a tailless aircraft with an instantaneous center of rotation located well forward of that of a conventional aircraft. This thesis examines how this center of rotation affected pilot handling qualities ratings. This effect should have been the most pronounced during approach and landing, and was where the testing focused. The goal of this research was to develop …
