Abstract In the drive for lower fuel consumption through increased bypass ratio and overall pressure (OPR), engine designs next generation of single-aisle aircraft will require core sizes below 3 lb/s OPRs above 50. Traditionally, these are domain centrifugal compressors, but materials limit in machines to well An all-axial high-pressure compressor (HPC) at this size, however, comes with limitations associated small blade spans back HPC, as clearances, fillets, leading edges do not scale...
The frequency-dependent free-field open-circuit voltage generated by radially polarized piezoelectric ceramic fluid-filled shells of infinite length coated with an elastic layer and excited a plane acoustic wave is studied. shell the coating are arbitrary thickness anisotropic. It shown that charge density in zero using electrostatic conditions. General expressions for pressures radial velocities interior exterior fluids obtained finiteness radiation conditions, respectively. stresses also...
An empirical model for estimating surface pressure spectra in high Reynolds number rough-wall turbulent boundary layers the low-speed regime is presented. The based on low-frequency mean velocity defect scaling [1] and high-frequency shear friction [2]. This satisfactorily predicts measured over a wide range of roughness configurations flows free transitional effects. These data also provide insights into characteristics scales which are order size comprise mid-frequency region. slope this...

With present-day rapid increases in the applications of radiofrequency microwave radiation research, medicine, defense, communications, and industry, it has become necessary to have simple inexpensive portable field strength meters for health safety surveys around operating equipment. This paper presents results a study conducted at Trombay calibrating grid evaluate receiving aperture efficiency 1-m long antenna narrow band electric meter, with frequency response centered 27.12 MHz. An 0.47...
