General Electric F414
From Canadian Power Wiki
The General Electric F414 is an afterburning turbofan engine in the 22,000-pound (98 kN) thrust class produced by GE Aviation. The F414 originated from GE's widely used F404 turbofan from the McDonnell-Douglas F/A-18 Hornet, enlarged and improved for use in the Boeing F/A-18E/F Super Hornet. The engine was developed from the F412 non-afterburning turbofan planned for the A-12 Avenger II, before it was canceled.
Variants[edit | edit source]
- F414-GE-400: Flies in the Boeing F/A-18E/F Super Hornet. Also proposed for the unbuilt naval F-117N variant of the F-117 Nighthawk.
- F414-EDE: "Enhanced Durability Engine" or "EDE", includes an improved high-pressure turbine (HPT) and high-pressure compressor (HPC). The HPT is redesigned to withstand slightly higher temperatures and includes aerodynamic changes. The HPC has been redesigned to 6 stages, down from 7. These changes aimed at reducing SFC by 2% and component durability three times higher.
- F414-EPE: "Enhanced Performance Engine" or "EPE", includes a new core and a redesigned fan and compressor. Offers up to a 20 percent thrust boost, increasing it to 26,400 pounds (120 kN), giving an almost 11:1 thrust/weight ratio.
- F414M: Used by the EADS Mako/HEAT. Derated thrust to 12,500 lbf (55.6 kN) dry and 16,850 lbf (75 kN) wet. Proposed for international versions of the Korean T-50 series of trainers and fighter aircraft, but later superseded by a new offer with a standard F414.
- F414G: Produced for the Saab JAS 39 Gripen Demonstrator. Slightly modified for use in a single engine Gripen, instead of a twin-engine aircraft like the F/A-18. With it, the Gripen Demonstrator reached Mach 1.2 in supercruise (without afterburner).
- F414BJ: Proposed for the Dassault Falcon SSBJ. Would produce around 12,000 lbf (53 kN) of thrust without use of afterburner.
- F414-GE-INS6: India's Aeronautical Development Agency selected the F414-GE-INS6 to power the HAL Tejas Light Combat Aircraft (LCA) Mk II for the Indian Air Force. India ordered 99 engines in October 2010. It produces more thrust than previous versions, and features a Full Authority Digital Electronic Control (FADEC) system.
- F414-GE-39E: New version of the F414G for the Saab JAS-39E/F Gripen.
- F414-KI: Variant of the F414-GE-400 co-developed by General Electric and Hanwha Aerospace for the South Korean KAI KF-X, to be manufactured jointly and assembled locally in South Korea by Hanwha Aerospace.
