fan pressure ratio

The ratio of the fan discharge pressure to the fan inlet pressure.

The system] varies the two propulsion parameters that impact thrust and specific fuel consumption: bypass ratio and fan pressure ratio," says ADVENT (ADaptive Versatile ENgine Technology) project manager at GE Aviation, Dave Jeffcoat.

By varying the fan pressure ratio and engine bypass ratio, a high thrust (high pressure ratio and low bypass ratio) state can be set for takeoff and acceleration.

Figure 1 illustrates how this fan pressure ratio reduction enhances propulsive efficiency at two levels of flight Mach number.

1) is largely determined by bypass flow in a high bypass engine the fan pressure ratio (which could be 1.

Featured column: as the turbine turns ... focus on fans

As the bypass ratio is increased, optimally the designer will drop the fan pressure ratio to maximize propulsive efficiency.
