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. Introduction A. Background IT takes around 5 years to develop a gas turbine engine, which then usually remains in pro- duction for more than two decades [1, 2]. -

Lockheed Martin F-35 Lightning II Incorporates Many Significant Technological Enhancements Derived from Predecessor Development Programs
AIAA AVIATION Forum 10.2514/6.2018-3368 June 25-29, 2018, Atlanta, Georgia 2018 Aviation Technology, Integration, and Operations Conference F-35 Air Vehicle Technology Overview Chris Wiegand,1 Bruce A. Bullick,2 Jeffrey A. Catt,3 Jeffrey W. Hamstra,4 Greg P. Walker,5 and Steve Wurth6 Lockheed Martin Aeronautics Company, Fort Worth, TX, 76109, United States of America The Lockheed Martin F-35 Lightning II incorporates many significant technological enhancements derived from predecessor development programs. The X-35 concept demonstrator program incorporated some that were deemed critical to establish the technical credibility and readiness to enter the System Development and Demonstration (SDD) program. Key among them were the elements of the F-35B short takeoff and vertical landing propulsion system using the revolutionary shaft-driven LiftFan® system. However, due to X- 35 schedule constraints and technical risks, the incorporation of some technologies was deferred to the SDD program. This paper provides insight into several of the key air vehicle and propulsion systems technologies selected for incorporation into the F-35. It describes the transition from several highly successful technology development projects to their incorporation into the production aircraft. I. Introduction HE F-35 Lightning II is a true 5th Generation trivariant, multiservice air system. It provides outstanding fighter T class aerodynamic performance, supersonic speed, all-aspect stealth with weapons, and highly integrated and networked avionics. The F-35 aircraft -

Air-Cooled Cylinders 1
Air-Cooled Aircraft Engine Cylinders An Evolutionary Odyssey by George Genevro Part 1 - From the Past Should aircraft engines be liquid-cooled or air-cooled? This “difference of opinion” is about a hundred years old and without a doubt the argument will continue as long as piston engines power the airplanes we fly. The manner in which the question is stated is misleading, however, since all waste heat that comes through the structure of an engine is eventually delivered to the air. In “liquid-cooled” engines the coolant can be water, ethylene glycol, a mixture of the two, or one of the many other liquids that have been tried and found wanting. Its primary purpose is to carry heat from the cylinder barrel and head to the radiator through which air, the actual cooling medium, flows. Proponents of liquid-cooling–now as in the past–can point to some benefits and operational advantages such as lessened hazard of shock cooling an engine, being able to direct dedicated coolant flow to critical areas in the cylinder head such as the exhaust valve seat and guide area, flexibility in radiator placement, greater structural rigidity in the engine, and having the option of designing airframes with a relatively small cross-sectional area that could still house a powerful engine. With every advantage, imagined or real, there is almost always a price to pay. Those who opted for liquid-cooled engines had to accept added weight, greater possibility of battle damage in military applications, and greater system complexity as the penalties. Such is life. -
