pub fn friction_issue_warnings(max_mach: Option<Peak>) -> Vec<IssueWarning>Expand description
The friction issue a flight on hpr’s own drag meets: #18 whenever it has a top Mach
number, at any speed and on any finish, since Barrowman 1967 gives no rule for when a surface
is too rough to stay laminar (LAMINAR_FRICTION_PERCENT). Apart from issue_warnings,
which reads the design’s shape.
