Structural analysis of annular combustors of aero gas turbines presents substantial challenges to engine-development establishments because of its multifunctional aspects such as complex geometry, thin wall structures, and stringent airworthiness requirements. This paper outlines an experimental methodology for fatigue life evaluation of an annular combustor casing using a closed-loop hydraulic test facility and presents results corresponding to the initial configuration. Premature fatigue failure has revealed that a design feature with a high stress concentration on the combustor casing needs to be modified. Iterative studies are taken up to overcome the design deficiency. This paper presents a unique approach whereby the experimental results for a full-scale annular combustor are correlated with numerical predictions for ensuring structural integrity in accordance with military airworthiness standards.

"The aim of this book is to identify that extra high-pressure ratio (such as about 70) civil aero engine low emissions combustors and extra high fuel air ratio (FAR) (such as FAR greater than 0.051) military aero engine combustors make up the next generation of aero combustors. The aero thermal design of these combustors is very different from previous combustors and the major design points are proposed. Two types of high-pressure low emissions combustor design have been suggested: one is without fuel staging and the other is with fuel staging. The high FAR combustor design is brand new. The layout of the next-generation aero combustor is very different. There are no primary holes, no intermediate holes, and no dilution holes. They all have direct mixing combustion. For low-emissions combustors, it is lean direct mixing (LDM) combustion. For high-FAR combustors, it is stoichiometric direct mixing combustion. Combustion air fraction is very high (such as greater than 75%). That will induce idle condition lean blow out (LBO) issue. The present book has proposed several design approaches to solve idle LBO issue, which are effective. Pilot fuel air combustion is designed at idle condition. For civil combustor, maximum condition is designed for low emissions, while for high FAR combustor, maximum condition is designed for non-visible smoke, low luminous flame radiation and good combustion efficiency. For each type of combustor, the fuel air module configuration is designed, which is the most essential part of combustor design. The brand-new combustor cooling design has used a compound angle tangential inlet cooling hole configuration. Such a cooling design provides high cooling effectiveness. The diffuser configuration is totally new. It is an air bleeding diffuser, directly stretching forward to contact the dome. The bled air flows to the annular channel as cooling air. Aero combustor development is discussed in this book. In particular, the combustor developments from technology readiness level (TRL) 3 to TRL level 6 have been discussed in detail. Also reported is the technology to run combustor development tests correctly. Three topics of related combustion research by the present author are summarized in the brochure. They are: a. Fuel injection and co-flowing air combination. The key point is, for next generation combustor development, the designer should not only think about atomization. The combination of fuel injection and co-flowing air should be considered together as a whole device. b. Fuel spray evaporation calculation, the key is an engineering calculation of multi-component fuel evaporation shall be used. c. Non-luminous flame radiation calculation, which has been significantly updated. The present book is a summary of the author's ten years of study on next-generation aero combustors after retirement. It represents advanced aero combustor technology level"--

Aircraft Propulsion and Gas Turbine Engines, Second Edition builds upon the success of the book’s first edition, with the addition of three major topic areas: Piston Engines with integrated propeller coverage; Pump Technologies; and Rocket Propulsion. The rocket propulsion section extends the text’s coverage so that both Aerospace and Aeronautical topics can be studied and compared. Numerous updates have been made to reflect the latest advances in turbine engines, fuels, and combustion. The text is now divided into three parts, the first two devoted to air breathing engines, and the third covering non-air breathing or rocket engines.
