Description

Technical Field

[0001] This application relates to the field of jet performance testing technology, and in particular to a volume-adjustable projectile. Background Technology

[0002] The Zeuch test method for constant-volume projectiles involves using a rigid, closed container with a fixed volume. The container is pre-filled with a medium (usually air or an inert gas) at a certain pressure and temperature. Fuel (liquid or gas) is then injected into the constant-volume projectile via an electronically controlled injector. Pressure sensors are used to collect pressure change curves before and after injection, and the injection mass and injection rate are calculated by combining these with the gas state equation.

[0003] The existing multi-purpose fuel injection performance testing device and method with publication number CN119267057A includes a test cartridge body and a pressure cap. The test cartridge body and the pressure cap together form a sealed test space. However, the volume of the test cartridge is fixed. In different application scenarios, the injection pressure, injection duration, and injection quality vary greatly. It is difficult to meet the multi-condition test requirements at the same time by simply adjusting the test conditions. It is necessary to replace the fixed-volume cartridge with a different volume or replace the entire cartridge body, which is cumbersome and costly. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an adjustable-volume ammunition, employing a split structure and an adjustable connecting cylinder. This allows for multi-condition testing by adjusting the ammunition volume, simplifying operation, eliminating the need to replace the entire ammunition, and significantly reducing costs. The technical solution is as follows: An adjustable volume spring includes a first sealing body and a second sealing body that are detachably connected, and a test space is provided between the first sealing body and the second sealing body; A connecting cylinder is located between the first sealing body and the second sealing body, and the connecting cylinder is detachably connected to the first sealing body and the second sealing body by at least two sets of fastening components; The first sealing body and the second sealing body together with the connecting cylinder form an adjustable volume test chamber.

[0005] Preferably, the first sealing body, the connecting cylinder, and the second sealing body are provided with coaxial mounting holes along the axial direction, and the fastening assembly is disposed in the mounting holes.

[0006] Preferably, the connecting cylinder has a through hole that connects to the test space, and the through hole and the test space together form the adjustable test cavity.

[0007] Preferably, a sealing assembly is provided between the connecting cylinder and the first sealing body and the second sealing body respectively for sealing; The sealing assembly includes a plurality of sealing elements, which are arranged radially to form a multi-layer sealing structure.

[0008] More preferably, the mounting holes are circumferentially distributed in the mounting configuration.

[0009] Preferably, the fastening component is a fastening screw.

[0010] Preferably, the first sealing body is provided with a mounting cavity, which communicates with the test space.

[0011] Compared with the prior art, the beneficial effects of this application are as follows: The first and second sealing bodies of this application are detachable, allowing for the replacement of individual components to be tested using different injectors. At the same time, it facilitates the installation or removal of components within the testing space, improving compatibility and eliminating the need for complete replacement, thus reducing costs.

[0012] Based on the above, a connecting cylinder is provided between the first sealing body and the second sealing body for detachable connection. By replacing the connecting cylinder with different sizes, the volume of the testing space can be adjusted, which can adapt to and meet the testing needs of different working conditions. The operation is simple and can further reduce costs. Attached Figure Description
