C130 Side
Sampling inlets on port side of NSF C130. The upper inlet is a counterflow virtual impactor (CVI) used to sample cloud droplets. Two of the NCAR HIAPER Modular Inlets (HIMIL) are visible, one on the side of the fuselage and one on the belly.
CVI In
Interior view of sampling port on side of C-130 fuselage. Structural modification of the airframe requires cutting one of the ribs and installing a window frame for attaching the inlet mounting plate.
Exterior view of external sampling port on C-130 fuselage. The cutout is about 11" wide and 7" high.
