Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Currently used propellants for mono- and bipropellant systems such as hydrazine, NTO, and MMH are highly toxic and therefore expensive to be implemented. So-called green propellants have drawn increasing interest in times with decreasing budgets for space missions and development tasks. They are promising a significant reduction of the overall development and operational costs at similar or better performance. FOTEC GmbH has developed a one Newton bipropellant thruster system operating exclusively with green propellants under contract of the European Space Agency. One of the main properties to be investigated was the ignition capability and ignition conditions of such new propellants. For the investigated system hydrogen peroxide (87 wt%) was used as oxidizer. Kerosene was selected as fuel and their suitability was investigated for such a propulsion system. Their auto ignition capability (quasi-hypergolicity) in the presence of decomposed hydrogen peroxide (i.e. steam and oxygen) has been investigated experimentally. An analytical non adiabatic auto ignition model of the ignition conditions for a choked and non-choked flow in a micro rocket combustion chamber has been developed assuming a one-step single forward chemical reaction and with consideration of a residence time distribution of the propellants. Special focus is laid on the pressure-temperature auto ignition behavior. 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In magnetoelectric multiferroics the onset of ferroelectricity is coupled to the onset of a magnetic structure that breaks the inversion symmetry. The dynamics of such coupled ordering transition can be probed via the dielectric response of the system. Generally, the question which type of ferroelectric transition (order-disorder or displacive) applies for multiferroics is important and DyMnO3 belongs to the most prominent members of this interesting material class. In the ferroelectric state, the Mn3+ spins form a cycloidal magnetic structure whereas in the paraelectric state, a collinear sinusoidal modulated spin structure is proposed to exist. However, the exact role in the formation of multiferroicity of the so-called collinear sinusoidal magnetic state, preceding the multiferroic state under cooling, is not yet fully clarified. Detailed dielectric studies near the spin-driven ferroelectric phase transition reveals the indication of an order-disorder type ferroelectric transition. Thus in the paraelectric state, a dynamical equilibrium of short range order cycloids with opposite chiralities exist instead of a sinusoidal modulated long range spin structure. 204 pp. Englisch.…
