Embodiment Construction

[0045] The injection device provided by the present invention is applied in the simulation system of the direct connection test environment of the new type of ramjet engine, and its structural composition is as follows: figure 1 shown.

[0046] The injection device adopts a modular design, which includes 8 steam injection units installed on the gas collection pipe 12. According to the injection requirements of different working conditions, a single or multiple steam injection units can be used to meet the requirements of the ramjet engine. Long-range heat test exhaust requirements.

[0047] Each steam injection unit includes a large-flow steam generator 21 with a working flow rate of 110kg / s and a group of two-stage steam injection pumps, wherein the two-stage steam injection pump consists of the first steam injection pump 17 and the second steam injection pump Composed of 18 series.

[0048] Both the first steam injection pump 17 and the second steam injection pump 18 are c...

Abstract

The invention discloses injecting equipment and an environment simulation system based on the injecting equipment, wherein the injecting equipment and the environment simulation system are used for the direct connection test of a novel stamping engine. According to the technical scheme of the invention, the equipment and the system solve the problems in the prior art that an existing test environment simulation system cannot simulate the air inflow condition and meet the requirement on the injecting capacity, and is low in injecting efficiency and large in investment scale. The injecting equipment comprises a plurality of steam injecting units arranged on the gas collecting pipe of the simulation system. Each steam injecting unit comprises a high-flow steam generator and a set of two-stage steam injection pumps, wherein the set of two-stage steam injection pumps is formed through the serial connection of a first steam injection pump and a second steam injection pump. The output end of the high-flow steam generator is respectively connected with the first steam injection pump and the second steam injection pump. The first steam injection pump is connected with the gas collecting pipe through a steam injection pipe. A first steam injection and isolation valve is arranged between the first steam injection pump and the gas collecting pipe. A second steam injection and isolation valve is arranged between the first steam injection pump and the second steam injection pump.

Description

technical field [0001] The invention belongs to the field of ramjet direct-connection tests, and relates to a ramjet ground test environment simulation system, in particular to an ejection device and a novel ramjet direct-connection test environment simulation system. Background technique [0002] The direct connection test is the most basic, important and effective test method in the ground test during the development of the ramjet. Most of the technical problems in the development of the ramjet engine can be found and solved in the direct connection test. The most important thing in the direct connection test of the ramjet is to simulate the total temperature, total pressure, and Mach number of the inlet and outlet of the engine, and at the same time, it is necessary to meet the ambient pressure at the outlet of the engine nozzle to make the nozzle work in the design state. That is, the system needs to realize the environmental simulation of the inlet flow and outlet boun...
