摘要:
A method and apparatus is disclosed for ejecting drug bearing material. The ejected material is ejected as liquid and liquid vapor via an explosive process which can provide a very fast ejection as well as an ejection which has a large throw. The apparatus can provide a nebulizer, inhaler or needleless injector.

The present invention relates to a reactor for the decomposition of ammonium dinitramide-based liquid monopropellants into hot, combustible gases for combustion in a combustion chamber, and a rocket engine or thruster comprising such reactor, wherein the reactor comprises a heat bed exhibiting catalytic activity.
摘要:
A system includes a turbine engine having a fuel injector. The fuel injector includes fluid ducts, each having a fuel inlet coupled to a distinct fuel source. The system includes a compressed air source that provides compressed air simultaneously to the fluid ducts, and a convergence point where combined fuel and air streams from the ducts are mixed. The fuel inlets are in a parallel flow arrangement such that no fuel from one fuel injector is present at another fuel injector.
摘要:
A gas turbine engine is piloted with a pilot flow of fuel delivered to a combustor as a liquid. A first additional flow of the fuel is also delivered to the combustor as a liquid. A second additional flow of the fuel is vaporized and delivered to the combustor as a vapor. A fuel injector may have passageways associated with each of the three flows.

A combustor assembly for a gas powered turbine includes a premix section to mix a first selected volume of fuel with a selected oxidizer. The premix section includes an injector plate that includes a porosity according to selected characteristics, such as pore size, pore density, pore distribution, and other selected characteristics. Therefore, the fuel may be provided through the porous plate to the premix area in a selected uniform flux.

The invention relates to an open-cooled component for a gas turbine having an outer wall (20) which is subjected to hot gas and which at least partly defines a first cavity (15) for a first medium and in which through-openings (3, 12) are arranged, which through-openings (3, 12) open into the cavity (15) on the one side and into the hot-gas space (21) on the other side, and having at least one second cavity for admixing a second medium, this second cavity being fluidically connected to the through-openings (3, 12). In order to specify a component for a gas turbine with which flashback and spontaneous ignition during feeding of fuel into the cooling air can be reduced, it is proposed that the second cavity be formed by supply passages (9, 13) which are provided in the outer wall (20) and are connected via transverse passages (4) to the through-openings (3, 12) designed as through-bores, so that the two media cannot be mixed until inside the through-bores. A combustion chamber for a gas turbine and a gas turbine having such a component are also proposed.
