Compressor
Thread Content
After the compressor reaches a controllable speed, it reduces its speed automatically according to the built-in program when the normal shutdown button is pressed. What impact does reducing the vacuum level before the compressor reaches its critical speed have on it?
You mentioned that reducing the vacuum level of the turbine before slowing down can affect the stability of speed regulation, and may even lead to an immediate shutdown.
Is this a requirement of your crew’s operating procedures?
