This research investigates the evaluation of passenger comfort during a cruise airplane trip. The flow fields in the comfort design in commercial aircraft create contour conditions for the diffusers, cabinets and geometry cabin, responsible for providing a healthy environment to the passengers. The objective of this work is to characterize the airflow by measuring the velocity field and the air temperature inside the cabin. Based on the actual data, a computational fluid dynamics (CFD) analysis was performed using the Autodesk programming language for the simulations, in order to obtain information about the possible standards of easy and seated comfort for the passengers. The results of particle dispersion in the cockpit showed great influence of the ventilation system and the location in the aircraft where people generate the particles. Based on these results, the internal layout of the BWB2 airplane, also known as “Flying Wing” was projected. The projected cabin furniture features ventilation in order to attend the passenger’s need in flight. It is noted that the incipient individualization of the passenger’s thermal comfort configures one of the biggest problems faced by the airlines. Consequently, It is a possible differential for competition between airlines.

The spread of the COVID-19 pandemic, caused by the SARS-CoV-2 virus occurs by the dissemination of viral infections, forcing the need for actions to control the virus. COVID-19 caused a pandemic that impacts the health system in biomedical and epidemiological order on a global. One of the measures taken by governors to contain the dissemination of the virus was the closure of airports, ports, and land borders, keeping only essential repatriation flights. The concern about agglomeration of people in public spaces causes the need for ventilation control in order to reduce the contagion and maintain hygiene in airports and planes. The sum of these factors brought, as a consequence, a resumption of decisions about how to adopt postures to control the contagion. Based on this analysis it turns out that ventilation is the fundamental factor to control the spread of the COVID-19 pandemic. In the civil aviation sector for passengers transport on planes and airports, the following related aspects are presented: (1) determining the air conditioning system coefficients in commercial airplanes for passenger transport using CFD (Computational Fluid Dynamics) simulations to check airflow; (2) present new hygiene technologies for planes and airports.
