  • 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].

  • Large Composite Fan Blade Development for Modern Aeroengines
    Volume I: Composites Applications and Design LARGE COMPOSITE FAN BLADE DEVELOPMENT FOR MODERN AEROENGINES Keith T. Kedward University of California at Santa Barbara Department of Mechanical & Environmental Engineering Santa Barbara, California 93106-5070, USA SUMMARY: The state of maturity of contemporary PMC’s after almost 30 years of scientific and technology development has resulted in a capability that far exceeds that available in the late 1960’s, and which, in 1989, prompted General Electric to engage in the notably successful development and flight certification of large PMC fan blades for their GE90 engine. In this paper an accounting of the specific enhancements in (i) constituent (fiber and matrix) property characteristics, (ii) fabrication and processing options, and (iii) design analysis methods combined with computational capabilities will be discussed. However, an equally important aspect is the variation in the design options that has resulted from evolving high by-pass ratio engine technology, which will also be addressed. The GE90 fan blade represents one of these options, being a relatively large blade designed to operate at lower tip speeds, thereby reducing the severity of the impact threat represented by the ingestion of large birds. A comparison between various modern turbofan engine fan blades and other rotor blades serves to indicate the important parameters and the difficulty of establishing a composite threshold range for rotor blades in general. KEYWORDS: polymer matrix composite, composite fan blade, constituent properties, impact performance, textile reinforcement architectures, engine certification INTRODUCTION Since the ill-fated attempt by Rolls-Royce to develop large polymer matrix composite (PMC) fan blades for a large commercial turbofan engine in 1968, i.e., the RB211, this potential application had eluded the engine designer until the emergence of General Electric’s GE90 engine development.

    European Aviation Safety Agency Notice of Proposed Amendment 2018-13 Appendix I to AMC to Annex III (Part-66) Aircraft type ratings for Part-66 aircraft maintenance licences RMT.0541 (66.024) EXECUTIVE SUMMARY This Notice of Proposed Amendment (NPA) addresses a regulatory coordination issue related to aircraft type ratings. According to the AMC to Annex III (Part-66), type ratings should be endorsed on an aircraft maintenance licence (AML) in accordance with Appendix I to AMC to Part-66 ‘List of type ratings’. An NPA is issued regularly to amend this list, after assessing feedback received from the industry, and to add new aircraft types or to remove aircraft types whose type certificate (TC) has been revoked or surrendered. This NPA adds also the tables of the new Group as a consequence of the introduction of the ‘L’ licence subcategories by Commission Regulation (EU) 2018/1142. The main objective is to ensure a common standard throughout the Member States. Action area: Regular updates/review of rules Affected rules: AMC/GM to Annex III (Part-66) to Commission Regulation (EU) No 1321/2014 Affected stakeholders: Maintenance certifying staff; maintenance training organisations; maintenance organisations; competent authorities Driver: Efficiency/proportionality Rulemaking group: No Impact assessment: None Rulemaking Procedure: Standard 12.5.2009 5.12.2018 2019/Q2 TE.RPRO.00034-008 © European Aviation Safety Agency.

  • An Investigation in Gold-Plating Scaled Turbofan Engine Simulators
    An Investigation in Gold-Plating Scaled Turbofan Engine Simulators through Means of Aerodynamic and Load Cell Thrust Measurements with Comparisons to Full-Scale Engine Results A Thesis Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Graduate School of The Ohio State University By Jacob T. Allenstein, B. Sci. Graduate Program in Aeronautical and Astronautical Engineering The Ohio State University 2013 Thesis Committee: Dr. Richard J. Freuler, Advisor Dr. Clifford A. Whitfield, Co-Advisor Copyright by Jacob T. Allenstein © 2013 ABSTRACT Model testing offers investigators a useful tool that can provide good insight into the aerodynamics behind full-scale engines and test facilities. Understanding the aerodynamics of a full-scale engine can help investigators update old test facilities and help design new facilities and engines. Gold-plating an engine is a process that the industry uses to compare the performance of an engine from the same family or class of engines in various facilities. The gold-plated engine can be used to determine a correlation factor of a testing facility or to determine the similarities in performance between a new or old engine to the gold-plated engine. The use of a correlation or correction factor can be used to correct a deviation in a measurement made in a test facility to bring the engine’s performance back to readings performed in a “free-air” environment. Model testing consists of the use of a simulator or scaled version of an engine that generates performance close to full-scale operation conditions. The simulator used in this study was constructed to not have any moving parts but rather be driven by a high pressure air system, providing a safe alternative to testing the full-scale engine.

  • Rolls-Royce Trent
    Rolls-Royce Trent Rolls-Royce Trent 900 on A380 prototype Rolls Royce Trent is a family of high-bypass turbofan engines manufactured by Rolls-Royce. All are developments of the famous RB211 with thrust ratings spanning between 53,000 to 95,000 lbf (236 to 423 kN). The name has also been used for a number of previous designs. Earlier designations The first Trent - a Rolls-Royce RB.50 Trent on a test rig at Hucknall, in March 1945 "Trent" was the name originally given by Rolls-Royce to the world's first turboprop engine (right). It was based on a concept provided by Sir Frank Whittle and derived by mating a five-bladed propeller driven through a reduction gearbox onto the company's Derwent II turbojet. It first flew on an experimental Gloster Meteor aircraft in the middle 1940s. The designation was reused again in the 1960s for the RB203 bypass turbofan which was designed to replace the Spey. It was the first three-spool engine, forerunner of the RB211 series. It was rated at 9980 lbf (44.4 kN). Present designation The current Trent is the development of the three-shaft RB211 family of engines. By 1987, a variant of the RB211, the RB211-524L, had been developed to such an extent that it bore little resemblance to the original RB211, other than the three-shaft layout. Rolls-Royce decided that the 524L would be the basis of a new engine family, and so the newest Trent was born. Rolls-Royce had started naming their engines after British rivers in 1942—a practice which was revived for the Trent after a 30-year gap.
