This paper presents a study regarding the noise reduction of turbojet engine, in particular jet micro engine. The results measurement campaign are presented followed by performances analysis which is based on measured data test bench. Within tests, beside baseline nozzle other two nozzles with chevrons were tested and evaluated. First type foreseen eight triangular chevrons, length being L = 10...

This paper is an analysis of a model for the structure in a liquid crystal medium that arises when the material is cooled from the smectic-A to the chiral smectic-C phase in a surface-stabilized cell with prescribed boundary conditions under a given electric field. This phenomenon causes V-shaped (chevron-like) defects to form in liquid crystal display devices and has attracted interest from bo...

Fluidic chevrons use injected air near the trailing edge of a nozzle to emulate mixing and jet noise reduction characteristics of mechanical chevrons. While previous investigations of “first generation” fluidic chevron nozzles showed only marginal improvements in effective perceived noise levels when compared to nozzles without injection, significant improvements in noise reduction characterist...

ID No. : FC-168 ABSTRACT Fiber-reinforced self-healing ceramic (shFRC) [1] is considered to be most attractive candidate of next generation structural materials using at high temperature, e.g. turbine blade, exhaust component of car engine etc. The shFRCs consist of three components, which are oxide fiber bundle, oxide matrix and self-healing agent interlayer. As the self-healing is generated a...
