The Boeing Rudimentary Landing Gear (RLG) is a new configuration used in an experimental project funded by Boeing and carried out at NAL (India). The RLG configuration has relatively large axles with square cross-sections and tripping the wheel boundary layers. The trips were designed by CFD in terms of location and size, and found effective. These peculiarities eliminate strong Reynolds number dependence of the previous SLG ("Simplified Landing Gear" by Lazos (2002)) case and enables running the simulations in the fully turbulent mode which, in turn, makes the assessment on the turbulence modelling more “clean” and relevant to the realistic high Reynolds number.

A preliminary description of the RLG configuration is provided here, See the description file for details.

Flow Parameters

The freestream velocity is 40 m/s. The Re number based on the wheel diameter (0.406m) and the freestream velocity is 1 million.


Meshes available for this case are listed in the table. Meshes marked with M are mandatory.


Simulation results available for this case are listed below.
