HYDROGEN TURBINE

Abrégé français

L'invention concerne une turbine à gaz permettant la génération efficace de puissance afin d'anticiper l'émergence de la « société de l'hydrogène ». Elle résout le problème technique de la conversion de l'hydrogène ou d'un autre gaz combustible en puissance rotative le plus directement. La solution présentée est une turbine à jet de gaz à grande vitesse, une centrale compact et légère. L'hydrogène et l'air sont pompés à travers un rotor multicaréné (A) par l'intermédiaire d'un stator multicaréné (B). La combustion se fait à l'intérieur du rotor, qui s'entraîne lui-même à l'aide des jets périphériques (13) et fait pivoter un arbre de travail extensible (15). Les principales utilités de cette invention sont l'alimentation de générateurs électriques et d'autres dispositifs exigeant une puissance rotative, notamment les véhicules marins, les véhicules terrestres et les véhicules aériens.

DESCRIPTION OF THE INVENTION
HYDROGEN TURBINE
TECHNICAL FIELD
The invention relates to a gas turbine for the efficient generation of power.
BACKGROUND ART
While in commonly known gas turbines gas exiting from a combustion chamber
drives the rotor with the
reactive force against the rotor blades where losses occur, the invention is a
pure reaction gas turbine
without rotor blades.
TECHNICAL PROBLEM AND ITS SOLUTION
The invention solves the technical problem of converting hydrogen or another
fuel gas into rotary power
most directly and thus improving efficiency. The solution is a multi-ducted
hollow rotor A. Hydrogen and
air are forced through the multi-ducted rotor A via a multi ducted stator B.
Combustion occurs inside the
hollow rotor A which drives itself with peripheral jets 13 rotating an
extending power shaft 15 at high
velocity.

DESCRIPTION OF HOW THE INVENTION WORKS WITH REFERENCE TO THE DRAWINGS
An electric generator, functioning as a start-up motor powered by an outside
electrical source, accelerates,
via a gear, rotor A to a high velocity. Air impeller 16 sucks air through
inlet port 20, forces it through
supply manifold 22, heat recovery ducts 23 and supply manifold 24, via exit
port 36, exit port 38, inlet port
7 and inlet port 8 into supply manifold 2 and into supply manifold 3 of rotor
A. whereby some air escapes
through labyrinth gap 37, labyrinth gap 39 and labyrinth gap 40.
Simultaneously, hydrogen gas is injected
through supply tube 21, via opening 34 and inlet port 6 into supply manifold 1
of rotor A, whereby some
hydrogen escapes through labyrinth gap 35. Rotor A, with its momentum, forces
the hydrogen gas through
supply manifold 1 and the air through supply manifold 2 and supply manifold 3
via mixer ports 4 into
mixing chamber 10 of combustor ducts 5 where hydrogen gas and air mix. From
mixing chamber 10 the
combustion gas passes by the electric ignitor 11 into combustor 12 where it
combusts and ejects as jet
through jet nozzle 13 into regenerator manifold 25, generating tangential
thrust driving rotor A directly.
Exhaust air and steam are cooling while forced through regenerator manifold 25
and through exhaust slots
26 and expelled as air and water into the ambient environment. Rotor shaft 15
powers, via the reduction
gear, the electric generator.
EXAMPLE
In the preferred application, installed in a vehicle, the invention drives,
with shaft 15, an electric generator
and thus is a compact and light weight power plant for electric vehicles.
