The problem of the estimation of the reliability of a metal-composite overwrapped pressure vessel for the electrojet engine unit of a satellite vehicle is considered. The functions of probabilities of failure-free performance according to impermeability and strength criteria are used as reliability characteristics. The peculiarities of the estimati...

Diese Arbeit dokumentiert eine experimentelle Parameterstudie zu passiven Schallabsorbern für Flugzeugtriebwerke (Liner). Methodisch stützt sie sich auf Versuche an Absorbern in einem Strömungskanal mit Mikrofonen. Damit werden mittels Schallfeldzerlegung die akustischen Streufaktoren Reflexion, Transmission und Dissipation bestimmt. Darüber hinaus...

A superconducting 15-pole 7.5 Tesla wiggler with a period of 200 mm is designed and manufactured at the Budker INP (Novosibirsk, Russia) and put into commission on the LSU-CAMD storage ring (Louisiana, United States) with an electron beam energy of 1.3 GeV. The synchrotron radiation generated by the wiggler allows the range of experiments to be exp...

Im Rahmen dieser Arbeit werden die Einsatzmöglichkeiten laseroptischer Geschwindigkeitsmessverfahren für strömungsakustische Anwendungen aufgezeigt. Particle-Image-Velocimetry (PIV) und Doppler-Global-Velocimetry (DGV) werden erfolgreich für die nicht-invasive Erfassung tonaler Schallfelder eingesetzt, wobei hauptsächlich das flächige PIV-Messsyste...

The problem of buckling of a thin elastic spherical shell inside a spherical cavity of uniformly contracting massive body is considered. This problem arises, for example, when designing pressure vessels made of composite materials with a thin metal cap layer. It is assumed that at the beginning of the compression the shell fits tightly against the ...

Experimental data for the acceleration of plate liners with a magnetic flux electromagnetic compressor are reported. The compressor is designed for peaking the power of current pulses with an initial amplitude of 3 MA. The compression zone of the liner has the form of a stripline, which makes it possible to use one current source both for the accel...

The possibility of in vivo, stress-induced oxidation in orthopaedic UHMWPE has been investigated. EtO sterilised, uncrosslinked UHMWPE liners, explanted or shelf-aged, have been collected. Linear wear and wear rate were assessed and FTIR spectroscopy was employed to detect oxidation and to build up oxidation products spatial maps across the liners ...

Magneto-inertial fusion (MIF) is an original technique of inertial thermonuclear fusion, where spherical and cylindrical gas or plasma configurations are compressed under the action of an external magnetic field. We present a brief review of recent data on laser- and plasma jet-driven MIF systems and possible ways they can be applied. This work als...
