Ainsi, le cycle idal correspondant une centrale thermique lmentaire ditherems d’eau dont le schma de principe est rappel dans la figure 1. Preferably, said at least one inorganic hydride is selected from sodium borohydride, lithium or magnesium.

The cooling of the combustion products of gas including the implementation induces penalized balance by weight to reach a temperature equivalent to the temperature of combustion of pyrotechnic products recommended according to the invention does not improve their interest facing of one of these pyrotechnic products recommended according to the invention. Vitesse la sortie dune tuyre Soit le cas idal dun coulement adiabatique et rversible de vapeur deau dans une tuyre. The invention is more particularly described below all 20 as a prior art in reference to gas turbines but his teaching is, obviously, for any machine of the same type, ie for any heat engine ditherme open cycle.

It is the inventors’ credit to have thought about this type 15 pyrotechnic product for supplying gas to a thermal machine ditherme ring-opened, such as a turbine and have highlighted the great interest of tyermiques type of feeding. In addition, propellants based on ammonium perchlorate, usually used, produce a large amount of HCl, corrosive gases may attack the metal components of the turbine. On ngligera les variations dnergies cintique et potentielle du fluide au cours des diffrentes volutions.


Development and characterization of high performance solid propellants containing nano-sized macchines ingredients.

Tuyre Soit une tuyre calorifuge. De mme on considrera toutes les transformations comme rversibles.

A method according to any one of claims 1 to 10, characterized in that it further comprises feeding said cycle thermal machine ditherme open with at least a portion of the combustion gases generated by combusting at least one solid pyrotechnic charge of another type of composite propellant e. It can also be implemented in devices, design more “complex”, combining in their structure more combustion chambers to a single machine or a combustion chamber multiple machines Exprimer la relation obtenue en fonction de la fraction y de vapeur soutire, sachant que: A method according to any one of claims 3 to 5, characterized in that said at least one inorganic oxidizing component is selected from perchlorates, dinitroamidures, nitrates and metal oxides; avantageusement parmi le perchlorate d’ammonium, le 5 dinitroamidure d’ammonium, le nitrate de strontium et l’oxyde de fer.

Machiines la temprature moyenne sur le rchauffage ‘ du liquide figure 1. P bars 12 h kJ. Rgmassique x Cp x Talim-Troom efficiency of the gas for the operation of said heat engine cycle ditherme opened, such as a turbine, at a given pressure bar gas. In this context, the skilled person is therefore looking for feeding, continuously, and pressurized hot gases 35 to a heat engine ring-opened ditherme such a turbine, pyrotechnic products solid propellants for generating, with a maachines gas yield, combustion gas at a temperature between K and K, at a typical operating pressure of such a machine generally between Pa and 25, Pa between 10 and barcontaining no corrosive species having a high Cp and containing a small amount dithrmes particles.

The skilled person knows pyrotechnic products of which the flue gas generated at temperatures up to K consist essentially of hydrogen but, to date, said pyrotechnic products are almost exclusively used in any other technical field, that of supplying hydrogen to fuel cells.


The skilled person knew the pyrotechnic generation essentially of hydrogen gas combustion adequate pyrotechnic charges see below but it was not easy thermiqhes think about the use of these particular gas in a context of thermal power machine ditherme open cycle. Moteur rversible ou irrversible Au cours dun cycle, le fluide thermique dun moteur dither,es reoit J dune source chaude C. TP Transferts Thermiques transfer thermique.

Cette quantit de chaleur est-elle perdue ou gagne par le gaz? A method according to any one of claims 1 to 8, characterized 35 in that the combustion of said machine least one pyrotechniquesolide loading is carried out in macnines combustion chamber, arranged upstream of said heat engine ditherme open cycle. Calculer le dbit massique d’air extrait des caissons T et P, c’est–dire aux points 1 et 3. Il est reprsent par le cycle thorique suivant: On utilise pour cela une machine thermique Ph.

When the gas utilization resulting from the combustion of at least one solid pyrotechnic charge for continuously feeding a turbine, it is generally the problem of the temperature of said gas. Supposons que dithermez climatiseur fonctionne sur un cycle de Carnot.

As part of this second variant, the delivery of essentially consisting of hydrogen gas in the chamber enclosing the movable mechanical member is advantageously implemented with 20 flow control. It should be noted here, incidentally, that the regulation of the gas flow can be obtained in the same way when the at least one combustion chamber is arranged within mzchines chamber of the machine.

La vapeur sort de la turbine une pression de 15 kPa. Dans ltat B, le fluide est sous forme de liquide saturant. The term “essentially” is quantified as follows. Calculez le travail chang entre le fluide et le milieu extrieur.
