Description

A camera designed for use in flight has been developed by the NACA Lewis laboratory t o photograph cloud droplets in their natural suspension in the atmosphere. A magnification of 32 times is employed to distinguish for measurement purposes all sizes of droplets greater than 5 microns in diameter. Photographs can be taken at flight speeds up to 150 miles per hour at 5-second intervals, A field area of 0.025 square inch is photographed on 7-inch-width roll film accommodating 40 exposures on an 18-foot length. Flight tests conducted in cumulus clouds have shown that approximate droplet-size distribution studies can be ... continued below

Description

A camera designed for use in flight has been developed by the NACA
Lewis laboratory t o photograph cloud droplets in their natural suspension
in the atmosphere. A magnification of 32 times is employed to
distinguish for measurement purposes all sizes of droplets greater
than 5 microns in diameter. Photographs can be taken at flight speeds
up to 150 miles per hour at 5-second intervals, A field area of 0.025
square inch is photographed on 7-inch-width roll film accommodating
40 exposures on an 18-foot length. Flight tests conducted in cumulus
clouds have shown that approximate droplet-size distribution studies
can be obtained and that a studies of the microstructure and physics of
clouds can be made with the camera.
