Vapour lock= cavitation?
Tree,
You seem to have a closer understanding than I do.
...Ive seen fire prorection tables that seem to show that aviation kerosenes with lower freeze points have lower flash points ; and elsewhere that tied to a fall in flash point is a fall in boiling point , at a roughly equivalent rate.
...Im getting at this -57c freeze point fuel being able to start bubbling with demand suction at an oat of 8-11 as it wamed up on final approach.
...Can you determine what the boiling point at MSL might be , and what would the inlet suction pressure have to fall to , to cause a further drop in boiling point (and gassing aeriation).?
