Said method is characterized by the nature of the gas supplied to said machine. The compositions in weight percent pyrotechnic products are given below: Il est reprsent par le cycle thorique suivant: Cette quantit de chaleur est-elle perdue ou gagne par le gaz?

Le fluide moteur est du fron. Cycle d’Otto On considre un cycle d’Otto dcrit par un gaz parfait reprsent figure ci -dessous. Tracer le cycle sur un diagramme de Clapeyron. Vitesse la sortie dune tuyre Soit le cas idal dun coulement adiabatique et rversible de vapeur deau dans une tuyre. On rappelle que, pour une transformation adiabatique, la temprature T et le volume V sont relis par la relation: En dduire la fraction y de la vapeur soutire, b Calculer: Cycle Diesel Le moteur dun vhicule automobile au gazole est un moteur atmosphrique qui fonctionne par autoallumage sans bougie du carburant inflammation spontane du gazole finement thermmiques inject dans de lair fortement comprim et chaud.

La transformation AB est une compression isentropique du gaz parfait. Their structure comprises, in the direction of gas flow therethrough, a chamber fed with hot gas under pressure, a movable mechanical element the rotor type with blades, piston La quantit de carburant injecte est faible devant la quantit dair et que la combustion du carburant ne modifie pas cette quantit dair, autrement dit le gaz circulant dans ce moteur sera considr comme une mme quantit dair seul tout au long du cycle.

For quantification of the term “substantially”, one refers to statements made early on in this text. On utilise pour cela une machine thermique Ph.

The presence of an organic binder, low rate is also not totally excluded to the extent that, in the context of the implementation of the inventive method, a high purity of the hydrogen generated is not required.

The process of the invention is in fact characterized by the nature of the relevant gas, gas generated by combustion of at least one original pyrotechnic charge. Thus, patent application FR teaches a cooling of the combustion gases prior to their injection into the turbine.

En dduire si le cycle est ralisable ou non ralisable. In a first variant, hydrogenated combustion gas is generated by burning at least one pyrotechnic charge 30 implemented within the thermal machine ditherme ring-opened, specifically into the chamber machine enclosing the element moving mechanical just upstream of said movable mechanical member.

Dans ltat B, le fluide est sous forme de liquide saturant. Mixtures of oxides of nitrogen and oxygen as oxidizers for propulsion, gas generation and power generation applications.

The combustion between the air and the fuel generates combustion gas 30 hot, pressurized by pressure in said combustion chamber.

Air entering the inlet nozzle is injected via the compressor into the combustion chamber equipped with at least one liquid or gaseous fuel injector. Ils produisent un Combustion temperatures of these solid pyrotechnic products are between K and K the joint use of at least one other pyrotechnic product 10 having a ditermes combustion temperature to K is not completely excluded from mafhines scope of the process of the invention but should, if said use involves a too high flue gas temperature, to provide a cooling of the generated combustion gases gases generated by the combustion of said at least one other product or only gas 15 resulting from the mixing of hydrogenated gas and gas generated by the combustion of said at least one other product and vary with the exact composition of these solid combustion pyrotechnics is stable at operating pressures of a thermal machine ditherme oes, such as a turbine.

Le cycle est rversible et dcrit dans le sens moteur. Dans cet autre domaine technique, les principales stipulations du cahier des charges sont les suivantes: NaCl, resulting from the combination of said NaNO3 with Cl ammonium perchlorate that may impact and damage the mechanical parts of the turbine. In the context of this variant, said at least one pyrotechnic charge 35 can be arranged in at least one combustion chamber itself arranged in said chamber containing the mobile mechanical element or directly in said chamber containing the mobile mechanical element this chamber then ensuring the combustion chamber functionfor example in a basket.
