Very simply, Microvanes generate swirl in direction opposite to natural aft fuselage vortices and reshapes air flow around the aft cargo door; thereby, reducing total drag and thrust requirements on the aircraft.
Extensive testing for flight (over 18,000 hours), wind tunnel, and Computational Fluid Dynamics (CFD) was completed from 2003-2014, validating Microvane safety and optimization of the design configuration to produce optimal drag reduction results.
While trend data was retrieved from the Post-flight Removable Memory Module (RMM), other impact and structural data was extracted from the Automated Inspection, Repair, Corrosion and Aircraft Tracking (AIRCAT) system.[/vc_column_text][/vc_column][/vc_row][vc_row type=”in_container” bg_parallax=”” color_overlay=”” vu_equal_height_columns=”” row_id=”” el_class=””][vc_column vu_vertical_align=”top”][vc_column_text]The following summarizes the aerodynamic performance tests and conditions that were evaluated with a focus on safety, drag reduction, optimization, and handling:
