Comparison of engine performance for different type of engines with alternative fuels during complete flight trajectory

Comparison of engine performance for different type of engines with alternative fuels during complete flight trajectory / Aiqa Arbila Abdul Halim
Airline industry has experienced a huge amount of improvements in fuel efficiency and this is due to the increasing harmful effects caused by them. One of the contributing approaches is using alternative fuels which are plant-based, and it wasn’t in vain as there have been three successful biofuel flights which are Air New Zealand’s Boeing 747-400, Continental Airlines Boeing 737-800 and Japan Airline Boeing 747-300. Thus, this study is conducted to compare and analyze the engine performance (thrust, specific fuel capacity, and mass fuel flow) of different type of engines (single-spool and double-spool engine) operating with alternative fuels (Jet- A, JSPK, CSPK, mixture of 50% JSPK + 50% Jet-A, mixture of 50% CSPK + 50% Jet-A, Palm Methyl Ester, Canola and Halophyte) during complete flight trajectory (take-off, top of climb, cruise, low power and ground idle). The engines are modelled, and the simulation is performed using the Gas Simulation Program software. This research analyzes the effect of alternating fuels on the engine performance during a complete flight trajectory. The results show that the best alternative fuel that could replace the conventional Jet-A is JSPK. It has the capability to produce similar and better engine performance in terms of thrust, lower specific fuel consumption and a reduction of mass fuel flow. JSPK blend, CSPK and CSPK blend fuels can also produce similar engine performance and used as alternative fuels. However, POME, POME blend, Canola and Halophyte are not able to produce similar or better engine performance compared to Jet-A fuel hence is not a suitable choice to replace the conventional Jet-A. This thesis draws the conclusion on the possibility of incorporating alternating fuels for GHC effects prevention. _______________________________________________________________________________________________________ Industri penerbangan mengalami peningkatan yang besar dalam kebolehan bahan bakar disebabkan peningkatan kesan yang berbahaya. Salah satu penedekatan yang menyumbang kepada peningkatan ini adalah penggunaan bahan api alternatif yang berasaskan tumbuhan. Pendekatan ini tidak sia-sia kerana terdapat tiga penerbangan biofuel yang berjaya iaitu Boeing 747-400 Air New Zealand, Continental Airlines Boeing 737-800 dan Boeing 747-800 Airline -300 Oleh itu, tesis FYP ini ditujukan untuk memahami analisis perbandingan prestasi enjin (teras, keupayaan bahan bakar tertentu dan aliran bahan bakar) dari pelbagai jenis enjin (jet tunggal, dan poros dua enjin) dengan bahan api alternatif (Jet-A, JSPK, CSPK, campuran 50% JSPK + 50% Jet-A,campuran 50% CSPK + 50% Jet-A, Metil Ester Sawit, Canola dan Halophyte) semasa trajektori penerbangan lengkap (pelepasan, penaikan, pelayaran, keturunan, dan pendaratan). Enjin dimodelkan, dan disimulasikan menggunakan perisian Program Simulasi Gas. Kajian ini menganalisis kesan bahan api alternatif pada prestasi enjin semasa trajektori penerbangan lengkap. Kajian telah merumuskan bahawa bahawa bahan bakar alternatif terbaik yang boleh menggantikan Jet-A konvensional ialah JSPK. JSPK mempunyai keupayaan untuk menghasilkan prestasi enjin yang serupa dan lebih baik dari segi tujah, penggunaan bahan api tertentu yang lebih rendah dan pengurangan aliran bahan api massa. Campuran JSPK, CSPK dan bahan api campuran CSPK juga boleh menghasilkan prestasi enjin yang sama dan digunakan sebagai bahan api alternatif. Walau bagaimanapun, campuran POME, POME, Canola dan Halophyte tidak dapat menghasilkan prestasi enjin yang serupa atau lebih baik berbanding dengan bahan bakar Jet-A dan bukan merupakan pilihan yang sesuai untuk menggantikan Jet-A konvensional. Tesis ini menarik kesimpulan mengenai kemungkinan menggabungkan bahan api berselang untuk pencegahan kesan GHC.
