The National Institute for Aviation (NIAR) Research's Virtual Reality Center, using exact data obtained from the aircraft’s CG (center of gravity) analysis, recreated and analyzed Amelia Earhart’s Lockheed Electra L10E aircraft ditching event in the Pacific Ocean. This animation shows the real-time water landing simulation. Learn more about the Virtual Reality Center (VRC) at the National Institute for Aviation Research (NIAR) in this article.

As seen here, the booster charge blows the frangible nut apart in the optimum location, minimizing any collateral damage.

Engine ground vortex ingestion occurs during ground maneuvering of transport airplanes. It poses foreign object damage and engine surge hazards, and it greatly hinders the ability to land in austere fields. The sprinkler system developed by Boeing utilizes high pressure bleed air from the compressor,which is plumbed to a valve located inside the engine cowl. The continuous jet is discharged through a nozzle that swivels intermittently, just like a sprinkler (1,2). The slew motion of the ejecting fluid disrupts the global flow in front of the engine and prevents the formation of ground vortices, thereby ensuring the operational health of the engine. The CFD simulation describes jet ejection by releasing particles from the sprinkler nozzles during the first five cycles from start of actuation (0.036 seconds, 140Hz).

 

 

 

The C-17 along with the sky and background was rendered with 3D Studio Max.  The particles were rendered in EnSight.  The two sets of images were overlaid in Adobe After Effects (which is also when the color bar and ERDC MSRC watermark was added) and rendered into a movie file.

The 600 time-step simulation shown is a free-surface flow past a NACA 0024 airfoil. Ensight was used to extract the isosurface of the flow, which was then exported for rendering in POV-Ray.

Douglas Dommermuth performed the simulation on the Cray T3E at the ERDC MSRC and Paul Adams performed the visualization. The Office of Naval Research supports the research.
