In this paper, the tooth flank form measurement of generated face-milled gears, face-hobbed gears and formulate/generated gears are reported. The authors discuss the advantages and disadvantages of scanning and point-to-point measuring of 3-D tooth flank forms of hypoid gears and introduce some examples of uses of measured data for high-quality.

The test rig contains a provision for changing the impedance charge without affecting the flow. Measurement examples are shown which illustrate the .

Publication date Time resolved pressure measurements on a compressor case were acquired for several uniform and non-uniform tip Pages: In the present paper, a simple analysis of the perturbed flow in an axial compressor stage with whirling rotor is presented, based on the actuator disc analysis of Horlock and Greitzer (), and.
The volute of a centrifugal compressor causes a non-uniform pressure distribution which leads to a radial force on the impeller. This force was measured using magnetic bearings. Liquid helium is constantly taken out of the dewar and warmed up to ambient. Mass flow is taken by a thermal flow meter.
The liquefaction rate is ∼s. In comparison to a TCF 20 under the same test conditions with conventional gas bearing turbines this is an improvement of 52 %.
The accuracy of the mass flow measurement is 4%. 22nd International Congress on Acoustics,ICA Buenos Aires – 5 to 9 September, Acoustics for the 21st Century 5 Table 1: Key parameters of C-3A test facility Linear size [m] ** Maximal rotational speed of the 1 st shaft [RPM] 12, Maximal rotational speed of the 2 nd shaft [RPM] 12, Maximal power of the 1st shaft [MW] Maximal power of the 2nd shaft [MW] These methods will be applied to measured data representing quite a large scope of events occurring during gas-turbine compressor operation, e.g.
synchronous engine order resonance crossing, rotating stall, suspected limit-cycle oscillations. Finally, the frequency estimates obtained from all these methods will be by: 7. The contact region transmits the forces from one body to the other by means of normal compressive stresses, and tangential or shear stresses when friction is present.
In an axial flow compressor, bladed discs are commonly mounted on a rotating shaft, together with a stator fixed to the by: The paper reviews new experimental technologies for the development of advanced fans with high bypass ratios.
Most of those developments are carried out in a highly specialized acoustic test facility available at the Central Institute of Aviation Motors (CIAM) in Moscow. The C-3A facility is equipped with an anechoic chamber specifically designed for acoustic, aerodynamic, and mechanical Author: Victor Mileshin.

This electronic book covers the topics of a university subject having the same title, and in which the Faculty of Electrical Engineering and Informatics of the Budapest University of Technology and Economics offers MSc courses.
According to its title, the book presents two, highly related technical fields. Five chapters deal with electrical switching devices and three with insulation technology.
The invention concerns a drive system, especially for a motor vehicle, with a multicylinder internal combustion engine, a device for shutting off at least some of the cylinders of the internal combustion engine, and a device for active reduction of rotational nonuniformities, acting in particular on a shaft, such as a drive shaft of the internal combustion engine, or a shaft that is coupled or Cited by: The flow visualization was realized by smoke pollution of the air supplied to the swirler.
In the course of the experiment, both temperature and total pressure fields of the flow were measured in axial and radial directions. Temperature distributions were employed for mixing coefficient (m) computing.

The invention concerns a drive system, in particular a drive system for a motor vehicle, including a drive unit, in particular an internal-combustion engine; an electrical machine which is coupled, or can be coupled, directly to the drive-unit drive shaft and which is designed so that it can start the drive unit from rest, turning together with the drive unit; and an automatic start/stop Cited by: 8.

SPIEInfrared Technology and Applications XXVI, pg (15 December ); doi: / Read Abstract +.Sinuous flow arises due to a surface plastic buckling instability and is characterized by repeated material folding, large local strains (>10) and energy dissipation.
The nature of this flow, its dependence on material properties, and manifestation across metals are directly observed.
