Abstract

A device for simulating an ingestion of chunks of ice by an engine, including: a main tank forming a cavity for a fuel, and connected to an inlet of the engine by a pipe; an injection system including an injection member arranged in the pipe; a secondary tank forming a cavity for a fuel, which tank is connected to the injection system by a selector member; and a reservoir connected firstly to a reserve of water and secondly to the injection system via the selector member. The selector member is configured to place the injection system selectively in communication with the secondary tank or with the reservoir to inject a determined quantity of water into the engine.

First claim

The invention claimed is:

1. A device for simulating an ingestion of chunks of ice by an engine, comprising:
a main tank forming a cavity for a fuel, and connected to an inlet of the engine by a pipe;
a cooling device for cooling the fuel in the main tank provided to the engine;
an injection system, comprising an injector arranged in the pipe;
a secondary tank forming a cavity for a fuel, connected to the injection system by a selector; and
a reservoir connected to a water reserve and to the injection system by the intermediary of the selector;
wherein the selector is configured to place the injection system selectively in communication with the secondary tank or the reservoir to inject a determined quantity of water into the pipe so as to form an ice slurry with the cooled fuel from the main tank provided to the engine via the pipe.

2. A device according to claim 1 , wherein the secondary tank is connected to a pressurizing member.

3. A device according to claim 1 , further comprising a system for regulating a flow rate of fuel between the secondary tank and the selector.

4. A device according to claim 1 , wherein the selector comprises a three-way valve that comprises three orifices, a first orifice being connected to the injection system, a second orifice being connected to the secondary tank, and a third orifice being connected to the reservoir.

5. A device according to claim 1 , wherein the water reserve is subjected to a determined pressure, and further comprising a filling member configured to connect the reservoir to a source of the determined pressure.

6. A device according to claim 5 , wherein the filling member is further in communication with the secondary tank and is configured to place the reservoir selectively in communication with the source of determined pressure or the secondary tank.

7. A device according to claim 5 , wherein the filling member comprises a three-way valve which comprises three orifices, a first orifice being connected to the source of determined pressure, a second orifice being connected to the secondary tank, and a third orifice being connected to the reservoir.

8. A device according to claim 5 , further comprising a valve arranged between the reservoir and the water reserve, configured to allow or prohibit circulation of water between the water reserve and the reservoir.

9. A device according to claim 1 , further comprising a system for evaluating the water injected into the pipe and arriving at the inlet of the engine.

10. A device according to claim 9 , wherein the evaluation system comprises a filter arranged on the inlet of the engine configured to recover the water injected into the pipe.

11. A device according to claim 9 , further comprising a container for recovering the water injected into the pipe.

12. A device according to claim 1 , wherein the injection system comprises an injection nozzle comprising an injection head with a flat tapered shape and having at its center an injection orifice, and a turbulator.

13. A device according to claim 12 , wherein the turbulator is placed in abutment against a wall of an inner space of the injection head, and is separated from the injection orifice by an injection channel.

14. A device according to claim 13 , wherein the wall of the inner space is of tapered shape.
