Your questions At what point (if any) does air stop getting sucked into the turbine and is just getting rammed in? On a CFM56-7B engine (Boeing 737 NG) pressure is provided by the fan, the low pressure compressor and the high pressure compressor with respective pressure ratios of about 1, 3 and 9, that is pressure is increased by a factor of 28 before air ...

Like any kind of vacuum system, vacuums cannot “suck“ anything. They just remove air from an enclosed space. This causes a pressure differential between the evacuated space and the surroundings. The higher air pressure outside forces air into the cassion; it is not “sucked” in. This is similar to the diffuser on a jet engine. The fan or compressor is ...

It is certainly possible to 'ram' air into a turbine. The maximum pressure that can be achieved is called the 'stagnation pressure', which is the point at which all incoming kinetic energy is converted into pressure energy. For some applications, this is good enough. For example, the Meredith effect is responsible for a slight amount of net thrust in the ...

The B787 is one type of implementation, others could vary. Yes, if you were able to zoom out enough you would see previous WPTs though they are no longer displayed on the active plan 'legs page' of the FMC CDU. Though I've shown the normal ND Map mode display below, there is another mode called Centered Map mode that displays the airplane at the center of a '...
