Along with my article on aircraft engines, I decided to write about the Pratt and Whitney F-135 turbojet engine. In this article, I will discuss the power capabilities of the engine. What he can and cannot do in reference to his performance. I'll also talk about who makes a particular engine and what that has to do with government. And finally, I'll touch on what aircraft it's used on and where the idea came from in the first place. The Pratt and Whitney aircraft company is a long-standing company in the aviation field. About two years ago, they released the F-135 engine for the F-35 Joint Strike Fighter. Figure 1 www.militaryparitet.com F-135Pictured above, the F-135 Pratt and Whitney engine prepares to be loaded into the rear fuselage of the F-35 Joint Strike Fighter aircraft. This particular engine has the same basic stages as any other jet engine. What are the intake section, the compression section, the combustion section and finally the exhaust section. Each of these sections has its own responsibility and plays an important role in the performance of the aircraft. Pratt & Whitney F135-PW-100 turbofan engine • Type: twin-shaft turbofan engine with low bypass ratio and afterburner • Bypass ratio: 0.2:1 • Low pressure compressor: three-stage fan • High pressure compressor: 6-stage axial flow compressor • Burner: “floating wall” through-flow annular combustion chamber • Turbine: dual counter-rotating body, single-stage axial high-pressure turbine, single-stage axial low-pressure turbine • Exhaust: jet pipe converging after combustion, divergent secondary nozzle with variable area, with 3-bearing swivel arrangement. • Rated thrust: 40,000 lb. thrust class with afterburner• Maximum military power (without afterburner): approximately 30,000 lbs. of thrust• Weight: 3,750 lb• Thrust/weight: 10.5:1• Mass air flow: approximately 200 lb/sec• Overall pressure ratio: approximately 30:1• Maximum turbine inlet temperature: 2,800 F+• Specific fuel consumption: 0.70 lb/lbt/hr (dry), 2.0 lb/lbt/hr (with afterburner) (TurboKart.com). Right on the Turbo Kart website I found the specifications of the F-135 jet engine. They take a detailed look at what the capabilities of the F-135 engine can do. This specific engine was designed for use in the F-35 fighter jet program. Lockheed Martin wanted to ensure it had all the equipment needed to meet the standards. However, with recent developments, the F-35 project has been put on hold due to engine problems..
