MTU/Pratt & Whitney RTF-180

Last updated

The MTU/Pratt & Whitney RTF-180 was a planned turbofan aircraft engine that was to be jointly developed by Motoren-und Turbinen Union (MTU) and Pratt & Whitney in the early 1990s. It was to be the first civil engine program where MTU would be the prime contractor. [1] The name of the engine, RTF-180, combined the initials for "Regional TurboFan" with the engine's nominal thrust of 18,000 pounds-force (80 kilonewtons). [2] : 6

A November 1990 internal briefing showed that the RTF-180 was one of the engines on offer for the 90-115 seat MPC 75, a regional airliner requiring 14,000–18,000 lbf (62–80 kN) of static thrust. [3] : M75.C.3005.A, M75.C.3008.B In March 1991, the RTF-180 engine was proposed as a possible powerplant for an 80-130 seat airliner from a consortium of Germany's Deutsche Aerospace (DASA), France's Aérospatiale, and Italy's Alenia. [4] The design of the RTF-180 for that airliner initially included a 137-centimeter diameter (54-inch) fan, three-stage low-pressure compressor, eight-stage high-pressure compressor, one-stage high-pressure turbine, and four-stage low-pressure turbine. [5]

At the 1993 Paris Air Show, MTU and Pratt & Whitney announced that they would abandon the RTF-180 in favor of a joint project with General Electric and SNECMA. [6]

<span class="mw-page-title-main">Turbofan</span> Airbreathing jet engine designed to provide thrust by driving a fan

A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust.

The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from 37,000 to 43,000 lbf. Built by Pratt & Whitney, they were designed for the Boeing 757. As a 757 powerplant, these engines compete with the Rolls-Royce RB211.

<span class="mw-page-title-main">Bypass ratio</span> Proportion of ducted compared to combusted air in a turbofan engine

The bypass ratio (BPR) of a turbofan engine is the ratio between the mass flow rate of the bypass stream to the mass flow rate entering the core. A 10:1 bypass ratio, for example, means that 10 kg of air passes through the bypass duct for every 1 kg of air passing through the core.

The Rolls-Royce RB.183 Tay is a medium-bypass turbofan engine, developed from the RB.183 Mk 555 Spey core and using a fan scaled directly from the Rolls-Royce RB.211-535E4 to produce versions with a bypass ratio of 3.1:1 or greater. The IP compressor and LP turbine were designed using technology from the RB.211 programme. The engine was first run in August 1984. The Tay 650 had a new HP turbine which incorporated new technology which had been proven with the RB.211-535E4. This engine also had a new combustor for improved durability. The Tay family is used on a number of airliners and larger business jets, including the Gulfstream IV family, Fokker 70 and Fokker 100, with a later version being used to re-engine Boeing 727-100s.

The Volvo RM8 is a low-bypass afterburning turbofan jet engine developed for the Saab 37 Viggen fighter. An augmented bypass engine was required to give both better fuel consumption at cruise speeds and higher thrust boosting for its short take-off requirement than would be possible using a turbojet. In 1962, the civil Pratt & Whitney JT8D engine, as used for airliners such as the Boeing 727, was chosen as the only engine available which could be modified to meet the Viggen requirements. The RM8 was a licensed-built version of the JT8D, but extensively modified for supersonic speeds, with a Swedish-designed afterburner, and was produced by Svenska Flygmotor.

The Kuznetsov NK-93 was a civilian aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. The engine was also unique in having a separate duct around the contra-rotating propellers, as most other propfans are unducted. Once described in a respected aviation encyclopedia as "potentially the most fuel-efficient aircraft jet engine ever to be tested", the NK-93 was targeted for derivatives of Soviet/Russian airliners such as the Ilyushin Il-96, Tupolev Tu-204, and Tupolev Tu-330. Five in-flight engine tests were conducted on the NK-93 from December 2006 to December 2008.
