Description

A TEST ASSEMBLY FOR DETERMINING THE EFFECT OF SHOULDER- LAUNCHED AMMUNITIONS ON THE SHOOTING PERSONNEL Technical Field of the Invention

The present invention relates to test systems used for shoulder-launched ammunitions and particularly a test assembly that determines the effect of the ammunition of the shooting personnel. State of the Art

Various standards have been determined so as not to harm the health of the shooting personnel by ammunitions such as shoulder-launched rockets and missiles etc. Parameters such as the force reaching the shooter's arms, the amount of toxic gas he/she breathes, the pressure to his/her chest, the loudness, the heat flow to the eye, etc. are required not to exceed specified values for different shooting configurations with these standards.

It is necessary to ensure that said requirements are fulfilled by tests before the ammunition is used by the shooting personnel. Many different sensors are used so as to fulfill all these requirements during these tests. Locating the sensors and the shooting platform are critical for getting proper results from the tests.

Aim of the Invention

The aim of the present invention is to introduce a sensor platform that can perform all the necessary measurements and can be used in different shooting configurations to determine the effect of shoulder-launched ammunition on shooter health.

The invention relates to a test assembly so as to determine the effect of shoulder- launched ammunition on the shooting personnel so as to fulfill said aim. The test assembly comprises a model body with a fixing apparatus at the shoulder part, such that the ammunition is adapted. In this regard, the invention provides a sensor platform that will be used in the test phase of shoulder-launched ammunition and can carry all the sensors that can take the necessary measurements for the health of the shooter. The ammunition is equipped with a tubular shooter in a preferred embodiment.

A preferred embodiment of the invention comprises a leg on which the model is raised. The leg provides a structure suitable for different shooting configurations. The leg can be in a single rising structure or in a table-like structure, for example, it can be applied to the model body with four legs. The model body can be fixed directly on the leg and also can be fixed by means of a carrier plate placed on the leg. On the other hand, it is also important to fix the legs on the floor. Therefore, anchor fixing elements can be adapted to the legs or can also be located on the floor with a fixing plate.

In a preferred embodiment of the invention, the leg is telescopically adjustable. Therefore, it can be configured according to different scales by being raised as desired. Telescopic legs for testing different shooter personnel heights and different shooting situations such as standing, kneeling, and ammunition fixing apparatus that can be fixed to these legs and can be located on the right and left side of the model body are used. Telescopic legs provide a compact structure during storage.

In a preferred embodiment of the invention, the leg comprises a rotary hinge that is adjusted at the bottom so that the model body can be tilted. The rotary hinge allows the model body to be tilted at the desired angle by rotating the leg. Therefore, it is possible to test straight and projectile shooting situations with ammunition.

In a preferred embodiment of the invention, it comprises a sensor system positioned on the model body. The sensor system allows detecting the effects of the ammunition through the model body.

In a preferred embodiment of the invention, the sensor system comprises a pressure sensor that is placed on the model body chest, an ear simulator that is placed close to the head and measures sound, a heat flux sensor that is placed close to the eye area and measures the amount of heat, a toxic gas sensor that is placed on the model body, a force sensor that is placed close to the shoulder area or necessary combinations thereof. In a preferred embodiment of the invention, the model body is configured in the form of a human body. Thus, it is possible to exhibit what kind of effects the ammunition is to cause on human body.

The inventive sensor platform for determining the effect of shoulder-launched ammunition on the shooting personnel essentially comprises the following;

- Ammunition to be measured (1 ),

- Ear simulator (2) representing human ear behavior,

- Heat flux sensor (3) that measures the heat flux reaching the human eye due to fuel combustion during shooting,

- Toxic gas sensor (4) that measures the amount of particles of the toxic gases caused by fuel combustion during shooting in the air,

- Model Body (5) with human sizes on which ear simulator (2), heat flux sensor (3), toxic gas sensor (4) and pressure sensor (6) are connected,

- Four pressure sensors (6) that measures the pressure on the chest of the shooting personnel during the shooting,

- The force sensor (7) that measures the force on the arms of the shooting personnel during shooting,

- Detachable fixing apparatus (8) that enables the ammunition (1 ) connection with telescopic legs (10),

- Carrier plate (9) that carries the model body (5) and is connected to the telescopic legs (10),

- Telescopic legs (10) that allow for a height adjustment for different shooting configurations,

- Middle plate (11 ) that supports the telescopic legs (10) and has angular freedom,

- Hydraulic legs (12) connected to the floor plate (13) and the middle plate (11 ) by rotary hinges,

- Floor plate (13) with holes thereon that can be used to be fixed on the floor,

- Rotary hinged legs (14) connected to the middle plate (11 ) with rotary hinges,

- Temperature sensors positioned on the ammunition tube (15).

A sensor platform for determining the effect of shoulder-launched ammunition such as rocket and missile on the shooting personnel is disclosed in this document. The ammunition (1) whose measurements will be made is fixed to two force sensor (7) located on the ammunition fixing apparatus (8) and adjusted based on the distance of the forearm and the rear arm. The ammunition fixing apparatus (8) is connected to the carrier plate (9) by means of the holes in the telescopic legs (10). The ammunition fixing apparatus (8) is in a modular form and can be positioned on the right or left side of the model body (5). Temperature sensors (15) are placed on the tube from which the ammunition (1) will come out.
