Numerical study of cargo bay turbulence of a transport aircraft

The Lockheed C-130 Hercules is arguably one of the most versatile fixed-wing transport aircraft available in any modern air force's arsenal. Besides transporting personnel, the Hercules may also take up goods and supplies for resupplement missions during peace and war times. In any case, mid-air ejection of goods and cargo via the tailgate always entails high risk for the C-130H and securing the airdropped goods’ integrity is of topmost priority. Upsweep forces and recirculation zones pose as hazardous environmental factors as they may cause extraction parachutes and goods to be blown off track or become damaged in the extraction process.MASTER OF ENGINEERING (MAE

Comparison of turbulence models in near wake of transport plane C-130H fuselage

This paper presents a computational fluid dynamics analysis of the delayed detached eddy simulation–shear-stress transport on a 1:16 scale simplified C-130H fuselage model in flight conditions and with a closed cargo ramp to observe the turbulent-flow structures that evolve behind its empennage region. The results of which are also compared against already existing x-vorticity plots of the delayed detached eddy simulation–Spalart–Allmaras with rotation and curvature correction. With vorticity magnitude of 750 rotations∕s, the delayed detached eddy simulation–shear-stress transport is shown to display a lot more detail in terms of the formation and unsteadiness of the upsweep and detached vortices. The simulations are performed with the finite volume solver Cobalt with up to 64 processors on a high-performance computer.Accepted versio
