...Haonan Jiang; Xiaochao Jin; Linchuan Liu; Xinkuo Ji; Xueling Fan We established and validated a radiant thermal test system using a miniaturized quartz lamp heating device designed with a novel search algorithm to meet aero-engine blade heating requirements. The device can perform rapid, high...

...Yun-Peng Zhu; Jie Yuan; Z. Q. Lang; C. W. Schwingshackl; Loic Salles; V. Kadirkamanathan High-cycle fatigue failures of fan blade systems due to vibrational loads are of great concern in the design of aeroengines, where energy dissipation by the relative frictional motion in the dovetail joints...

... delivered by the impeller with dimensionless design parameters. The approach incorporates both impeller geometry and flow conditions and, therefore, is inherently able to predict the slip factor both at design and off-design conditions. Five impeller cases are used to demonstrate the efficacy of the method...

... demonstrated reductions in fuel burn and NO x of up to 6.93% and 8.74%, respectively. The developed method constitutes a rigorous approach to guide the design of control systems for future advanced rotorcraft. e-mail:  calum.scullion@cranfield.ac.uk e-mail:  vourosstavros@windowslive.com e...

...Enrico Mattarelli The paper proposes some design criteria for the MotoGP engines, complying with the FIM 2007 Technical Regulations. Five configurations have been considered: engines with three cylinders in line and four cylinders in line, and three V engines with four, five, and six cylinders. All...

...K. Cen; P. Basu; L. Cheng; M.-X. Fang; Z.-Y. Luo The present paper discusses the goals and methods of design of a circulating fluidized bed (CFB) boiler: A 62-MWt (75-T/h) CFB boiler was designed manually using experience and available published data. The design was regenerated by an Expert System...
