Abstract

A gas turbine ejector comprises an outer shell, a middle shell, an inner shell and a powder feeding pipe. The right end of the outer shell is provided with an air inlet used for being connected with a gas turbine; the middle shell is arranged in the outer shell, and a gap exists between the middle shell and the outer shell to form a gas turbine tail gas auxiliary flow channel; the inner shell is arranged in the middle shell, and the right end part of the middle shell is connected with the right end of the inner shell; a gap exists between the middle shell and the inner shell to form a powder injection flow channel; the powder feeding pipe penetrates through the outer shell and the middle shell and is communicated with the powder injection flow channel; and a gas turbine tail gas main flow channel is arranged on the inner shell. Gas turbine high-speed jet tail gas is divided into two paths after entering the ejector, one path passes through the gas turbine tail gas main flow channel, the other path passes through the gas turbine tail gas auxiliary flow channel, and the gas turbine high-speed jet tail gas is branched, so that the gas turbine high-speed jet tail gas is prevented from blocking and pressure building, and the back pressure influence on the gas turbine is avoided.

Description

technical field

[0001] The invention relates to the technical field of cigarette-generating vehicles, in particular to a gas turbine ejector for a cigarette-generating vehicle. Background technique

[0002] The gas turbine ejector is an accessory of the smoke-generating vehicle of the smoke-generating force, and is mainly used to provide part of the power and flow path for the smoke-generating vehicle to generate infrared interference smoke screen. The smoke-generating vehicle can provide smoke screens and interference environments for relevant actual combat exercises of the troops, increase actual combat exercise items, simulate actual combat scenarios, and enrich the combat experience of combatants in smoke screens and interference environments.

[0003] The gas turbine ejector is used for matching with small gas turbines. However, the existing gas turbine ejector has air resistance to the ejected airflow, the ejection speed is low, and it is easy to cause the high-speed ...
