Rotary-wing aircraft emergency landing control

摘要

An emergency landing control system for an aircraft includes a landing site data source, a performance margin data source, an engine health data source, an aircraft health data source, and a processor. The landing site data source determines, continuously and in real-time, available landing sites. The performance margin data source conducts, continuously and in real-time, continuous performance analysis of an engine. The engine health data source determines, continuously and in real-time, available engine power as a function of time. The aircraft health data source determines, continuously and in real-time, available aircraft life as a function of time. The processor receives data from these data sources and, based on these data, continuously generates landing paths to one or more of the available landing sites, and selectively and continuously adjusts maximum available engine power up to emergency power limits, as needed, during execution of a landing maneuver to a landing site.

主权项

1. An emergency landing control system for an aircraft that includes at least one engine, the system comprising:
a landing site data source configured to determine, continuously and in real-time, one or more available landing sites, and to supply landing site data representative thereof; a performance margin data source configured to conduct, continuously and in real-time, a continuous performance analysis of the engine, and to supply performance margin data representative thereof; an engine health data source configured to determine, continuously and in real-time, available engine power as a function of time, and to supply engine health data representative thereof; an aircraft health data source configured to determine, continuously and in real-time, available aircraft life as a function of time, and to supply aircraft health data representative thereof; and a processor coupled to receive the landing site data, the performance margin data, the engine health data, and the aircraft health data and configured, based on these data, to continuously generate landing paths to one or more of the available landing sites.
