Robust Gas Turbine and Airframe System Design in Light of Uncertain
Robust Gas Turbine and Airframe System Design in Light of Uncertain Fuel and CO2 Prices Stephan Langmaak1, James Scanlan2, and András Sóbester3 University of Southampton, Southampton, SO16 7QF, United Kingdom This paper presents a study that numerically investigated which cruise speed the next generation of short-haul aircraft with 150 seats should y at and whether a con- ventional two- or three-shaft turbofan, a geared turbofan, a turboprop, or an open rotor should be employed in order to make the aircraft's direct operating cost robust to uncertain fuel and carbon (CO2) prices in the Year 2030, taking the aircraft pro- ductivity, the passenger value of time, and the modal shift into account. To answer this question, an optimization loop was set up in MATLAB consisting of nine modules covering gas turbine and airframe design and performance, ight and aircraft eet sim- ulation, operating cost, and optimization. If the passenger value of time is included, the most robust aircraft design is powered by geared turbofan engines and cruises at Mach 0.80. If the value of time is ignored, however, then a turboprop aircraft ying at Mach 0.70 is the optimum solution. This demonstrates that the most fuel-ecient option, the open rotor, is not automatically the most cost-ecient solution because of the relatively high engine and airframe costs. 1 Research Engineer, Computational Engineering and Design 2 Professor of Aerospace Design, Computational Engineering and Design, AIAA member 3 Associate Professor in Aircraft Engineering, Computational Engineering and Design, AIAA member 1 I.

Comparison of Helicopter Turboshaft Engines
Comparison of Helicopter Turboshaft Engines John Schenderlein1, and Tyler Clayton2 University of Colorado, Boulder, CO, 80304 Although they garnish less attention than their flashy jet cousins, turboshaft engines hold a specialized niche in the aviation industry. Built to be compact, efficient, and powerful, turboshafts have made modern helicopters and the feats they accomplish possible. First implemented in the 1950s, turboshaft geometry has gone largely unchanged, but advances in materials and axial flow technology have continued to drive higher power and efficiency from today's turboshafts. Similarly to the turbojet and fan industry, there are only a handful of big players in the market. The usual suspects - Pratt & Whitney, General Electric, and Rolls-Royce - have taken over most of the industry, but lesser known companies like Lycoming and Turbomeca still hold a footing in the Turboshaft world. Nomenclature shp = Shaft Horsepower SFC = Specific Fuel Consumption FPT = Free Power Turbine HPT = High Power Turbine Introduction & Background Turboshaft engines are very similar to a turboprop engine; in fact many turboshaft engines were created by modifying existing turboprop engines to fit the needs of the rotorcraft they propel. The most common use of turboshaft engines is in scenarios where high power and reliability are required within a small envelope of requirements for size and weight. Most helicopter, marine, and auxiliary power units applications take advantage of turboshaft configurations. In fact, the turboshaft plays a workhorse role in the aviation industry as much as it is does for industrial power generation. While conventional turbine jet propulsion is achieved through thrust generated by a hot and fast exhaust stream, turboshaft engines creates shaft power that drives one or more rotors on the vehicle. -

2013 ANNU A L REPORT SHAREOWNER LETTER—2014 March 1, 2014 We had very good performance in another “weakish” year in the global economy. We were able to grow sales 4% to $39.1 billion and earnings per share* by 11% to $4.97. Our segment margin rate grew 70 basis points to 16.3% and free cash flow** grew to $3.8 billion, a 96% conversion rate.** As usual, we also took the opportunity to continue our seed planting…products, technologies, restructuring, geographies, services, processes, new capacity…to ensure that growth continues far into the future. Five-Year Plan The year 2014 is the last in the five-year plan (2010-2014) Honeywell introduced in March 2010. Despite economic and foreign exchange headwinds versus what we assumed then, we’ve performed quite well as you can see from the chart below. Sales ($B) Segment Margin Rate $40.3- $41.0- 16.6- 16.0- 45.0 18.0% $39.1 40.7 16.3% 16.9% 13.3% $30.0 2009 2013 2014E 2014 Target 2009 2013 2014E 2014 Target We estimate that those headwinds versus our original macro assumptions cost us about $3 billion in sales over the 2010-2014 period. Even with those headwinds, we expect to almost touch the bottom of the targeted sales range growing sales 6% annually and expect to be around the midpoint of the margin rate range (a margin rate increase of approximately 350 basis points). While there was a lot of skepticism in 2010 about our five-year plan, our performance has generated a lot of interest in the next five-year plan covering 2014-2018. -
