Mach number

That same year, she co-authored the report "Effects of Nose Angle and Mach Number on Transition on Cones at Supersonic Speeds," the first of around a dozen research reports she would produce for the space agency.

She then became an aerospace engineer specializing in aerodynamics in 1958, co-authoring her first report that same year: “Effects of Nose Angle and Mach Number on Transition on Cones at Supersonic Speeds.”

The results of the work would come to fruition in 1958, in Mary’s first report, coauthored with Czarnecki: “Effects on Nose Angle and Mach Number on Transition on Cones at Supersonic Speeds,” published in September 1958.

Fujino discovered the optimum Over-The-Wing Engine Mount configuration, which reduces wave drag at a high Mach number, and applied it to the HondaJet, a clean sheet design.

His final Mach number was 1.25.
