1800K is still 1.6Kc so that isn’t realistic for intake temperature either.
At Mach3 the SR-71 airframe got to just under 500c at the hotspots.
The reentry temperature of the space shuttle peaked at around 1600c.
1.6-1.7K is the temperature of modern afterburners so if 1800c/k is a figure of anything it would be that.
That said the turbine entry temperature for modern jet engines is about 800c so maybe the 1 was a typo.
