Nuclear Helicopter Air Density Indicating System Flight Test Program
Abstract
This report describes the design, construction, and testing of the Nuclear Helicopter Air Density Indicating (NUHADI) system. The NUHADI measures the scattering of X-rays, generated by an isotopic source, from the air volume outside the helicopter. The number of X-rays backscattered into the detector is proportional to the number of molecules per unit volume, i.e., the air density. The air scatter signal is compared to an internal signal, from the same source, during each cycle to provide a continuous self calibration.
