2. Description of Related Art

The spread progression of SARS-CoV-2 around the world has risen a red flag: Economic economic globalization creates systemic risks. As trade, finance, travel, cyber and other networks grow in scale and interact, they become more complex and unstable. The transporters of the goods of the global economy, such as major airport hubs, are also spreaders of the pathogens. The 2008 global financial crisis provided a dramatic example of how contagions could spread from the US to global markets overnight. So too has the rapid spread of cyber viruses. In health, rising life expectancy and success in preventing a repeat of the devastating influenza pandemic of 1918, which infected about one-third of the world's population and killed as many as 50 m people, has created a false sense of security. But the world is now more interdependent. For example, China represents almost one-fifth of global output, is integral to global supply chains, and its tourists spend over $260 billion annually. The CovidCOVID-19CoVID-19 pandemic shed light on the need for better monitoring, detecting, and isolating ill passengers, specifically due to the havoc that was wreaked detrimental impact on the global economy, specifically air travel due to closed borders, movement restrictions, and testing requirements.

However, the COVIDCoVID-19 pandemic the air travel industry has proven that air travel can be safe and that aircraft cabins have a well-managed airflow that inhibits minimize the risk for transmission of virus, and that being seated onboard an aircraft is safer than shopping in large stores. Governments and other authorities need to assume that aircraft are contaminated until proven “clean”, as 25% of COVID-19 cases are asymptomatic or pre-symptomatic; but still contagious. Thus, if borders shutdown and a drastic reduction in international travel global passenger travel is greatly reduced. To date travelers and governments have relied on individual diagnostic tests. The uncertainty of the results has reduced people's inclination to travel and subsequent airline inclination to maintain routes.

Accordingly, there is still a need in the art for virus and pathogen detection systems and methods. The present disclosure provides a solution for providing a test and analyzing a test aboard an aircraft.

SUMMARY OF THE INVENTION

A system for monitoring aircraft air is disclosed. The system includes a collector for collecting particulate samples positioned within at least one of an outlet flow path or a recirculation flow path of an environmental control system of an aircraft, wherein the collector is accessible to a user within the cabin of the aircraft. The collector is out of line of sight view of cabin crew while in a collecting position. The collector becomes accessible by a lift, an access gate, or a roller to the user within the cabin of the aircraft. The particulate samples include droplets exhaled from passengers throughout a duration of a flight. The collector can include a filter material. The collector can include an adaptor and a filter material operatively connected to the adaptor. The adapter can include a frame and the filter material is mounted to the frame. It is also considered that the collector can be portable within the cabin of the aircraft.

The system can also include a mounting slot in the outlet flow path upstream from the outflow valve, wherein the collector is positioned within the mounting slot. The collector can be configured and adapted to be removed from the mounting slot for testing by using a lift or roller.

A method of collecting particulates from aircraft air is also disclosed. The method includes capturing particulates in an outlet flow path with a collector for a period of time, wherein capturing particulates is unaided by a pump in order to move the air to the collector, removing the collector from at least one of the outlet flow path or the recirculation flow path for testing, inserting a clean collector into at least one of the outlet flow path or the recirculation flow path for use during another period of time. The recirculation flow path can be based on inherent pressure differences within the aircraft cabin, galleys, and cargo bay. The method can include doing a Polymerase Chain Reaction (PCR) test on at least one particulate captured in the collector, and relaying a result of the PCR test to a central data center, wherein the period of time is a duration of a flight, and wherein the PCR test is done on-board an aircraft after the duration of the flight to determine if the aircraft is virus free upon arrival. The collector can include an adaptor and a filter material operatively connected to the adaptor, the method further comprising removing the filter material from the adaptor. The adapter can be cleaned using a solution containing isopropyl alcohol.
