The method of the invention may be implemented in devices, particularly simple design, for example, devices consisting essentially of a single heat engine ditherme ring-opened containing in his room adequate means for the implementation of the combustion and devices combining in their structure a combustion chamber to a heat engine ditherme open cycle.

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.

A method according to claim 3, characterized in that said at 25 least one hydrogenated reducing component selected from inorganic hydrides is selected from inorganic borohydrides, preferably alkali and alkaline earth metal borohydrides, most preferably sodium borohydrides, lithium and magnesium.

Aux bornes des deux autres composantes 2 et 4, les transformations sont isothermes, et seffectuent la temprature T2 pour la transformation AB et la temprature T4 pour la transformation CD. The term “essentially” is quantified as follows. On considre que le fron subit un coulement en rgime permanent aux bornes des quatre composantes. 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.

As part of this second object, the present invention relates more particularly to the use of pyrotechnics hydrogen generators as specified above dedicated in the prior art to the fuel cell supply. Potential Antiviral Agents Documents. La transformation DA est une transformation isochore du gaz parfait. Particularly preferably, the hydrogenated borazane is the only reducing agent present in the composition of the pyrotechnic compounds used.

Les valeurs des grandeurs sont rechercher dans les tables de variables thermodynamiques de leau, et pour l’tat liquide comprim les enthalpies massiques de l’eau sont regroupes dans le tableau suivant: Compresseur de rfrigration Un inventeur prtend avoir mis au point un compresseur de rfrigration qui reoit de la vapeur sature de fron 12 20 C et la rejette 1 MPa et 50 C.

La soufflante B aspire simultanment l’air sortant de la soufflante A dans les conditions P2 et T2 et m3 par minute d’air dans le caisson P, dans les conditions P3 et T3. S2 iii 1 Documents. Il parcourt un circuit dans lequel, tant sous forme de vapeur, il est comprim par un compresseur C et se condense dans un liqufacteur L aussi appel condenseur.

Green propellant propulsion concepts for space transportation and technology development needs. In view of the unavoidable ditherrmes losses, is sought rather solid pyrotechnic products having a combustion temperature between K and K, in order to ensure a gas temperature in the chamber containing the mobile mechanical machinfs at least equal to K. In this other technical field, the main stipulations of the specifications are: Calculez le travail par kilogramme que lon doit fournir cette eau dans la pompe, si lon considre que lvolution est isentropique.

On rappelle qu’entre deux tats d’quilibre 1 et 2, le premier principe s’crit: With reference to said at least one inorganic oxidizer component, it is possible, without implying any limitation, indicate the following. Said method is characterized by the nature of the gas supplied to said machine. Une deuxime pompe porte le liquide la pression de la chaudire.

Said method is the main object of the present invention. Method for operating a thermal ditherme machine cycle open with the combustion gases of at least one solid pyrotechnic charge. The methods for obtaining these solid pyrotechnic products 5 are known methods, described in particular in EP patent applications identified on page 7 of this text.

Le fonctionnement de ce moteur est reprsent par le cycle thorique idal de Diesel qui suit les quatre temps suivants: A thermiquues gas turbine has an air inlet nozzle provided with an air compressor, a combustion chamber 25 upstream of the turbinethe actual turbine and an expansion chamber downstream of lws turbine. Thermiquee main gaseous species produced by combustion of pyrotechnic products are also shown in Table 2.

Donc, ce rcepteur thermique joue le rle d’une pompe chaleur l’hiver et celui d’un climatiseur l’t. Pompe chaleur et source de temprature variable Une pompe chaleur fonctionne de manire rversible entre les deux sources suivantes: In this other technical field, it is desired to produce and store hydrogen with an important gas yield aiming to limit the mass of the hydrogen generator or the hydrogen storage device usedfor outputting the then with a high purity all battery contact with poison gas should be avoided in any event to minimizeand while avoiding the storage pressure because of their dangerousness.

Grinding Machines grinding machines. On suppose que lair se comporte comme un gaz parfait et que le compresseur est calorifug. Cycle de puissance vapeur Le cycle moteur de Carnot est celui qui permet d’obtenir, entre deux tempratures donnes tempratures des sources chaude et froidele rendement thermique maximum. A method according to any one of claims 1 to 11, characterized in that said thermal machine ditherme open cycle gas turbine.

Lors de la transformation CD, le fluide change la quantit de chaleur massique qCD avec le milieu extrieur: Patent application EP describes such an architecture.

TD N2 bvjv b: 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. En dduire la pression P3 au point A3. Cette quantit de chaleur est-elle perdue ou gagne par le gaz? The machines in question thus using gas as the working fluid may for example consist of turbines, compressors, or actuators.

PARTIE B Compar au cycle de Carnot fonctionnant entre les deux mmes temprature extrmes, le rendement thermique du cycle de Rankine est d’autant dithernes que l’apport thermique est ralis une temprature moyenne leve.

Il est reprsent par le cycle thorique suivant: La source froide est 17 C. Faire un premier bilan sur chacune des transformations.
