Specifications for the F-16 Block 52 Aircraft Engine

The Block 52 F16 is an enhanced version of the original two-seat F16 fighter. It was first flown in 1991. The 52 series incorporated the most substantial changes to the F16 since its introduction in 1974. Block 52 models have increased payloads and fuel capacities, new avionics and an advanced color cockpit display. Longer-range radar detection against air targets and the capability to fire the Maverick missile and deploy new JDAM smart bombs make the Block 52 an enhanced weapons platform. It is also the first F16 to use the Harpoon anti-ship missile. The power in the Block 52 comes from a single Pratt and Whitney F100-PW-229 Improved Performance Engine; it is lighter and more powerful than previous Pratt and Whitney F100s, producing 22 percent more thrust.

Thrust
- The F100-PW-229 is an afterburning turbofan that produces 17,800 lb. of dry thrust. In afterburner mode, the thrust is 29,160 lb. The thrust-to-weight ratio is 7.8-to-1.
Performance
- Installed in a Block 52 F16, the F100-PW-229 delivers a maximum short endurance speed of Mach 2.85 and a maximum sustained speed of Mach 1.89. Its tactical interdiction radius, with six 500-pound bombs and internal fuel only, is 360 miles; its maximum ferry range, with external fuel tanks, is 2,450 miles.
Compressor and Turbine
- The compressor in the F100-PW-229 is a dual-spool axial design with three fan and 10 compressor stages. The bypass ratio is 0.36-to-1. The turbine has two low-pressure and two high-pressure stages.
Fuel Consumption
- The F100-PW-228 is rated at 0.76 lb. of fuel per hour-pound of thrust at standard military thrust and 1.94 lb. of fuel per hour-pound of thrust in afterburner mode.
Dimensions
