Turbofan The turbofan gas turbine engine is the same as a turboprop, except that a duct-enclosed, axial-flow fan (Figure 1-14) replaces the reduction gearbox assembly and prop. The fan is either part of the first- stage compressor blades or mounted as a separate set of fan blades. The high pressure turbine drives the high pressure compressor (N2) and the low pressure turbine drives the fan (N1). The fan uses 30 to 60 percent of the available propulsive energy. The propulsive efficiency, thrust, and fuel consumption for the turbofan engine falls somewhere between those of the turbojet and the turboprop engines. Some examples of what the Turbofan engine powers are the F-18, F-110, F-111for military use, and Boeing 787 for commercial use. Figure 1-14 — Pratt and Whitney F-119 engine. ENGINE DESIGNATION SYSTEMS The engine designation systems use standard symbols to represent the type, manufacturer, and model of aircraft engines used in military. Knowing the designation systems gives you basic information about the engine. Two engine designation systems are in use today. The old system is under Air Force-Navy Aeronautical (ANA) Bulletin No. 306. The new system is under MIL-HDBK-1812 and includes all newly developed gas turbine engines of the Air Force, Army, and Navy. ANA Bulletin No. 306 will remain in effect until all engines manufactured before the introduction of MIL-HDBK-1812 have had a change to the configuration, the performance, or been dropped from service. MIL-HDBK-1812 The purpose of this standard is to provide type designation systems and procedures for use by the Department of Defense to standardize the identification of photographic equipment, aerospace vehicle propulsion engines. Aeronautical equipment, support equipment, and electronic material. In addition this standard defines the method for obtaining nomenclatures and type designations. Type Indicator The type indicator part of the engine designation shall consist of the appropriate type letter symbol, together with a type numeral. The type numeral used in connection with the type letter shall be assigned consecutively by the services, beginning with number 100 for the Air Force, 400 for the Navy, and 700 for the Army.
