General Electric F414

General Electric F414 is a high-bypass turbofan with afterburning and low-pressure ratio of 98 kN thrust manufactured by GE Aviation. Derived from the F404 model, which powers the McDonnell Douglas F/A-18 Hornet, the F414 is used in the Boeing F/A-18E/F Super Hornet. This engine was developed from the prototype F412 without afterburning, intended to power the McDonnell Douglas A-12 Avenger II before the project was canceled. Variants F/A-18 Super Hornets are powered by two F414-GE-400 engines each. F414-GE-400 The Boeing F/A-18E/F Super Hornet is equipped with this engine. It has also been proposed for powering the F-117N, a naval variant of the F-117 Nighthawk. F414-EDE "Enhanced Durability Engine" or "EDE," features an improved high-pressure turbine (HPT) and compressor (HPC). The turbine was revised to handle higher temperatures, and includes aerodynamic modifications. The compressor was simplified, reducing from 7 stages to just 6. These changes aim to reduce the SFC by 2% and triple the lifespan of components. F414-EPE "Enhanced Performance Engine" or "EPE," features a new core (HPC), as well as redesigned turbine and compressor. It offers up to 20% more thrust, approximately 26,400 pounds (120 kN), resulting in a weight-to-thrust ratio of 11:14. F414M Used on the EADS Mako/HEAT trainer aircraft. This is a version where the dry thrust was reduced to 12,500 pounds (55.6 kN) and the "wet" thrust to 16,850 pounds (75 kN). It has been proposed for equipping the international version of the T-50, but was eventually replaced by a standard F414. F414G Equips the Saab JAS 39 Gripen demonstrator. The main modification is to run the engine solo, as the Gripen is a single-engine aircraft, unlike the dual-engine F/A-18. The Gripen achieved supersonic cruise speeds of Mach 1.2 using this engine. F414BJ Proposed for the Dassault Falcon SSBJ (SuperSonic Business Jet). Projected thrust: 12,000 pounds (53 kN) without afterburning. F414-GE-INS6 The Indian Aeronautical Development Agency has selected the F414-GE-INS6 to power the indigenous HAL Tejas Light Combat Aircraft (LCA) Mk II, which equips 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. The F414-GE-INS6 will have 6 stages. Engines are scheduled for delivery in 2013. F414-GE-39E New evolution of the F414G for the Saab JAS-39E/F Gripen.
