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]. -

IV. TRADE POLICIES by SECTOR (1) 1. Switzerland and Liechtenstein
WT/TPR/S/141 Trade Policy Review Page 90 IV. TRADE POLICIES BY SECTOR (1) INTRODUCTION 1. Switzerland and Liechtenstein have followed a piecemeal approach to their trade reforms. The nature and pace of implementation have tended to vary according to sector. Important reforms have liberalized market access considerably in several manufacturing and services subsectors. The bilateral mutual recognition agreement with the EU, and amendments to competition legislation and to sectoral regulations (e.g. on pharmaceutical products and motor vehicles) have further liberalized the Swiss manufacturing sector since 2000, at least as far as Swiss-EU trade is concerned. In Liechtenstein, the liberalization reforms in manufacturing and services have largely been spurred by its 1995 EEA membership. 2. Several Swiss and Liechtenstein multinational companies are among the world's largest, and many competitive and innovative small and medium-sized export-based companies have developed with little or no government assistance. The main exceptions are the electricity and gas subsectors, and certain industries with low productivity, notably in food manufacturing, certain construction products and services, or salt production. Despite relatively high tariff protection, the textiles and clothing and (particularly) the footwear industry, have recorded the strongest contraction in value added in Swiss manufacturers over the past decade. 3. In agriculture, implementation of reforms has slowed since 2000. Switzerland (and through it Liechtenstein) continues to rank top among the OECD countries in terms of government support to agriculture, despite the ongoing gradual move away from price support towards direct payments. High border protection has contributed to maintaining domestic food prices high by international comparison. -

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.
