The US Air Force Research Laboratory (AFRL) has shown that common ground heaters could be used to raise the temperature of aircraft interiors to levels sufficient to kill the coronavirus and other biological contaminants.

Flight Global reported that in two tests conducted in May 2020, the interior of a Boeing C-17 cargo aircraft was sealed using materials common to military installations and was heated to 10°C (50°F) above ambient temperatures over a six-hour period, the AFRL stated recently.

The heaters used in the experiment are found at all military bases, and are commonly used by maintenance crews to keep warm or to heat equipment.

“Our goal with this test was to demonstrate the ability for any Air Force base to assist with aircraft disinfection utilizing only commonly available equipment and materials,” says Doug Lewis, team lead of the 711th Human Performance Wing Protection Systems, which is leading the effort.

“We knew that if we could prove the ability of this equipment to heat aircraft interiors to temperatures in the [49°C] range, we were potentially demonstrating an Air Force-wide disinfection capability, pending further laboratory results.”

Aircraft heating could be reapplied to commercial airliners or business jets, providing a cheaper and more effective means for cabins to be disinfected. However, the six-hour period used in the experiment would likely be too time consuming during normal airline operations as aircraft are often expected to turn around within less than an hour.

Airlines and charter operators currently use a variety of methods to clean aircraft cabins including spraying disinfectant and using strong UV lights to kill viruses that may linger on surfaces after infected passengers leave their seats.

The AFRL is working with research organisation Battelle to measure the effectiveness of heat to inactivate the coronavirus. Early results appear promising, it says.

“Preliminary results from Battelle indicate that the temperatures reached during the AFRL tests were sufficient to disable the virus to safe levels on surfaces materials including aluminum, silicon, and nylon webbing,” the AFRL added. (Thisday)
