Abstract
Data are reported for both airborne and wind tunnel testing
of the aerosol inlet on the CIRPAS Twin Otter research aircraft.
Though utilizing different instrumentation and assumptions, results
from the two test venues show broad agreement. The roll off
in transmission efficiency of the inlet under standard flight conditions
starts at ∼3.5 μm but plateaus at 5.5 μm particle diameter
at a value slightly in excess of 0.6. This value persists to the upper
limit of the test range at 9 μmand is likely due to the sub-isokinetic
aspiration flow of the inlet.
