According to its second object, the present invention therefore relates to the use of at least one solid pyrotechnic charge whose combustion gases are essentially composed of hydrogen to the gas feed of a thermal machine ditherme ring-opened, such a gas turbine.

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 higher combustion temperature to K is not completely excluded from the 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 dithermfs 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 dithfrmes 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 ring-opened, such as a turbine.

Calculer le dbit massique d’air extrait des caissons T et P, c’est–dire aux points 1 et 3.

Use of at least one solid pyrotechnic charge whose combustion gases are essentially composed of hydrogen to power, gas, thermal machine ditherme open cycle, and in particular a gas turbine.

Regarding the pressure parameter, the combustion of managing at least one pyrotechnic charge for obtaining the hydrogenated gas to the desired pressure between Pa and 25 Pa 10 and baradequate to the correct operation of the machine does not pose any particular difficulties in the art.

Grinding Machines grinding machines. En dduire les expressions du 1er principe et du 2ime principe de la thermodynamique dans le cas d’un coulement ERP. The presence of impurities is not excluded. Toutes les transformations sont supposes quasi statiques. It, however, that the combustion gases or pressurization generated must be “essentially” made of hydrogen.

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. Synthesis of exo, exo-5,6-Dideuterio-synacetoxynorborene and exo,exo-5,6-Dideuterionorbornene Documents.

We saw above that at least part of said combustion gas is used for said power supply and the thermal machine ditherme open cycle in question turbine, for example may also be parallel jointly supplied by pyrotechnic gasderived from another source. Green propellant propulsion concepts for space transportation and technology development needs.

Le fluide moteur est du fron. Cycle de rfrigration On tudie, ici, le fonctionnement dun rfrigrateur. 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.

A method according to any one of claims 1 to 8, characterized in that the combustion of said at least one solid pyrotechnic charge is carried within said thermal machine ditherme open cycle. En dduire les expressions du 1er et du 2ime principes en fonction du dbit dentre me.

Air mchines the inlet nozzle is injected via the compressor into the combustion chamber equipped with at least thermisues liquid or gaseous fuel injector. Dans ltat B, le fluide est sous forme de liquide saturant. 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 this type of feeding.

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.

TD Chim exercises chem. Typically, said combustion gases consist essentially of hydrogen, ie at least substantially solid pyrotechnic charge generates hydrogen by combustion. In addition, propellants based on ammonium perchlorate, usually used, produce a large amount of HCl, corrosive gases may attack the metal components of the thefmiques. Pompe chaleur et source de temprature variable Une pompe chaleur fonctionne de manire rversible entre les deux sources suivantes: On utilise pour cela une machine thermoques Ph.

Thermoques 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 machinea composite propellant e. The main gaseous species produced by combustion of pyrotechnic products are also shown in Table 2.

Calculez le travail par kilogramme que lon doit fournir cette eau dans la pompe, si lon considre que lvolution est isentropique. Calculer le rendement de ce moteur de Carnot. Alkali metal or alkaline earth metal borohydride and strontium nitrate Sr NO3 2 containing solid compositions for generating hydrogen by combustion. Utilisation selon la revendication 13, d’au moins un chargement pyrotechnique. The compositions in weight percent pyrotechnic products are given below: A strong gas Cp is shown to reach high pressures to a temperature compatible with the thermal resistance of the mechanical elements of a thermal machine ditherme open cycle, such a turbine.

Product combustion gases whose use machinrs recommended according to the invention hydrogen generator are generated them at an acceptable temperature suitable for direct feeding a thermal machine ditherme ring-openedin particular a gas turbine.
