Fw190/BMW 801 Why no CHT

[Bert_Foster]

Why didn't the BMW801 in the FW190 have a Cylinder Head Temperature gauge ? pretty much every other Radial engine on the planet does and its vital to Engine operation.

Kommandogerat

I understand Kommandgerats basic function and operation but What has Kommandgerat have to do in controlling CHT ? ....

[II/JG17_HerrMurf]

Engine management was fully automated. Monitoring CHT by the pilot would have been redundant.

[Bert_Foster]

Why ? what Engine management controlled by Kommandgerat can control CHT ?

With an efficient control system, you know the engine will stay within safe CHT a) permanently, on nominal power, b) within a relatively long time on combat power and c) within a relatively short time on emergency power.

 

I haven't read through the Fw-190's manual but I'm sure it specifies time limits for each and every engine power settings. That way pilots only need to control usage of throttle settings other than nominal and the engine control does the rest, and you do away with a gauge that although important in most aircraft is redundant here.

CHT is a function of power, mixture and, in most radials, cowl flaps. Two out of three are controlled by the KG. A3 has fixed louvers and no cowl flaps. So everything is already accounted for. Kurt Tank tried to minimize much of the "flight engineer" aspect in the cockpit so the pilot could concentrate on flying and fighting.
