Abstract: Systems and methods for generating an alert if a rotary wing aircraft is approaching a hazardous situation. In an example method a processor receives a wind value and a rate of descent value. An alert signal is generated if the received wind value is greater than a tailwind threshold value and the rate of descent value is greater than a rate of descent threshold value. The generated alert is outputted to an output device, such as a display device or speakers. The alert signal is further generated if the rotary wing aircraft is on approach to landing, a rate of change of heading is less than a predefined value, or a rate of change in speed is less than a predefined value.

Abstract: A centrifuge is employed to continuously remove particulates from a fluid. In one embodiment, the centrifuge removes small particles of soot from lubricating oil of large diesel engines. The fluid in introduced into the centrifuge through an inducer so that vortexes are not propagated in the fluid. Flow constrainers and flow straighteners maintain laminar flow of the fluid as it passes axially through the centrifuge. An exducer decelerates the fluid prior to its exit from the centrifuge. The exducer thus contributes to maintaining laminar flow conditions. Laminar flow may contribute to the soot-removal effectiveness of the centrifuge.

The processing device also issues a cabin depressurization alert over the alerting device based on at least one of the set alert volume or alert frequency, if there is a problem with the cabin pressure value.

The Geiger-Muller tube collects the electrons from the back scattered radiation.
