The US government has planned to conclude a contract with representatives of the American industry, involving the reverse development of the heat exchangers of the load of the strategic stealth bomber B-2 Spirit, writes The Drive.
According to the American publication, we are talking, in particular, about the need to replace the heat exchanger core. It is noted that the heat exchanger itself uses air and ethylene glycol to produce cold air for the cooling system.
“Although it is difficult to say exactly why this approach (reverse engineering – approx.” Lenta.ru “ ) is used now, it indicates that the original documentation for these components is not available or the manufacturing processes and tools used in their production no longer exist “, – writes The Drive.
The publication assumes that, for example, the relevant documentation may have been lost. The Drive admits that the contractor manufacturing the components to be replaced may have ceased to exist.
The publication notes that the obsolescence of the aircraft of the Air Force (Air Force) of the United States makes the task of reverse engineering for already not mass-produced elements of aircraft more and more urgent. This problem, according to The Drive, can be solved by the timely use of digital twins.
In February, the American magazine Aviation Week & Space Technology reported that the problems of the strategic stealth bomber B-21 Raider created by the American corporation Northrop Grumman had been eliminated. The publication recalled that, probably, it was about problems with the air intakes of the B-21 Raider, which required “serious overhaul.”
