Hereinafter, an apparatus and method for verifying aircraft survival equipment related to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram showing an apparatus for verifying aircraft survival equipment related to the present invention.

The apparatus for verifying aircraft survival apparatus illustrated in FIG. 1 includes a threat simulation unit 100 for simulating a signal of a threat and a monitoring unit 200 for monitoring a response of the aircraft survival equipment including a threat detector in response to the simulated signal. ) Is included.

As shown in FIG. 2, the aircraft survival equipment (ASE) includes a threat detector 510 for detecting various threats in a real-time battlefield environment, a response device 530 for deceptive threats, and a threat detector. It consists of a survival equipment management computer 550 that manages the equipment and makes decisions about how to respond.

Threats refer to objects that are dangerous for normal operation of the aircraft, such as missiles intended to shoot down aircraft, detection radars to detect aircraft, and tracking radars to guide missiles to detected aircraft. Such threats use lasers, infrared rays, and RF signals to effectively detect and track aircraft operating at high speeds.

The threat detector 510 is a device for detecting a threat and includes means for detecting a laser, an infrared ray, and an RF signal that are generated and emitted from a threat. For example, the threat detector can be a laser warning receiver (LWR) 511 for detecting lasers, a missile warning receiver (MWR) 513 for detecting missiles using infrared / laser / RF signals. And a radar warning receiver (RWR) 515 for detecting an RF signal.

Response equipment 530 is a means of firing / spinning chaff, flare, and jamming signals to deceive a threat, such as a missile. An example is the Air Force's Chap Flare Launcher, called the Counter Measures Dispenser System (CMDS).

Survival equipment management computer (Electronic Warfare Computer) 550 manages threat detectors and response equipment, and makes decisions about how to respond. For example, if both the MWR and RWR respond to a missile that targets an aircraft in a threat detector, the survival equipment management computer determines that it is a radio tracking missile and causes the response equipment to launch the chaff. In addition, if only the MWR responds to the missile, it will determine that it is an infrared / thermal tracking missile and have the corresponding equipment fire flares.

As described above, the preliminary verification of the aircraft survival equipment composed of the threat detector, the response equipment, and the survival equipment management computer is performed at the basic level of performance verification by checking the messages between the components due to the limited verification environment. Therefore, it is difficult to know the problems that may appear when mounted and operated in the actual aircraft. As a result, a lot of resources are wasted due to the situation of stopping the aircraft operation and repairing the onboard aircraft survival equipment in order to solve the problems during the operation of the aircraft. In addition, since the actual performance verification of the completed aircraft survival equipment through the operation of the aircraft is difficult to obtain data to improve the performance of the aircraft survival equipment.

To solve this problem, we need a means to simulate the situation of aircraft survival equipment on board the aircraft as closely as possible. The threat simulation part 100 is used as such a means.

The threat simulation unit 100 simulates a signal of a threat. The threat simulation unit 100 may include at least one of a laser generator, an infrared generator, and an RF signal generator to generate a simulation signal that is as close as possible to the actual threat. In order to simulate the signal of a real threat, the threat simulator needs data about the signal generated and emitted from the threat which can be provided for the aircraft on which the aircraft survival equipment is to be mounted (including incidental information on the threat if necessary). Such data may be stored in a database (not shown) available in the threat simulation unit or transmitted from external means such as a scenario application unit described below. The simulated signal of the present specification also includes a laser generated in the laser generator and an infrared ray generated in the infrared generator.

The laser generator, the infrared generator, and the RF signal generator constituting the threat simulation unit are preferably provided to the aircraft survival equipment, specifically, the threat detector of the aircraft survival equipment as the same signal as the threat. However, depending on the verification environment, it may be difficult to provide the same signal as the threat. For example, when performing verification in a confined space, it is difficult for the RF signal generator to generate and emit the same RF signal as the threat. This is due to the antenna characteristics of the RF signal detectors of aircraft survival equipment, such as RWRs, which detect RF signals. Due to the characteristics of the antenna, a certain distance is required to apply an RF signal that is the same as or similar to a threat, and the distance is difficult to be satisfied in a limited space. Therefore, the RF signal generator may generate an antenna output signal of the RF signal detector included in the threat detector and transmit the generated antenna signal to the antenna output terminal of the RF signal detector. That is, in an environment where it is difficult to simulate the RF signal of the threat, the RF signal generator may simulate the antenna output signal of the threat detector that receives the RF signal of the threat instead of the RF signal of the threat.

In this way, the RF signal of a threat can be simulated in a limited space. However, the data about the output signal of the antenna receiving the RF signal of the threat should be known through experiments.

Laser generators, infrared generators may also generate output signals from laser sensing sensors, such as antennas, and infrared sensing sensors, such as RF signal generators. However, since the laser generator and the infrared generator can achieve the same state as in the field even in the limited space, it is preferable to generate the laser and the infrared ray except in a very limited place. This allows the verification of laser and infrared sensors.

The threat simulator may adjust the simulation signal according to the simulation distance between the simulated threat and the aircraft survival equipment.

The monitoring unit 200 monitors the response of the aircraft survival equipment in response to the signal simulated by the threat simulation unit.

The response of aircraft survival equipment to threats consists of the detection of threats, the determination of optimal countermeasures to threats, and the implementation of the determined measures. Threat detection is done by the threat detectors, countermeasure decisions by the survival equipment management computer, and execution of the determined measures by the counterpart equipment. Therefore, the monitoring unit monitors the response of the aircraft survival equipment by confirming the operation of the threat detector, the survival equipment management computer, and the response equipment after the threat simulation unit is driven. To do this, the monitoring unit must know whether the threat simulation unit is running. The monitoring unit instructs the threat simulation unit to generate a simulation signal, checks whether the threat simulation unit is driven, or receives the driving status from the threat simulation unit to know the driving and driving schedule of the threat simulation unit.

Figure 3 is a block diagram showing a monitoring unit of the aircraft survival equipment verification apparatus related to the present invention.

The monitoring unit 200 shown in FIG. 3 includes a simulation display unit 210 for simulating display means interoperating with the aircraft survival equipment and a corresponding analysis unit 230 for analyzing the operation of the aircraft survival equipment.

The monitoring unit monitors the response of the aircraft survival equipment to the detected simulated threats. In addition, the monitoring unit can also monitor the status of the radar indicator, which is an indicator of interlocking with the aircraft survival equipment. The radar indicator mounted on the aircraft is a means for displaying a threat detected by the threat detector of the aircraft survival equipment, and a means for allowing an aircraft pilot to check the existence of a threat. Radar indicators allow pilots to either manually deal with threats or allow aircraft survival equipment to take appropriate action. In other words, radar indicators play an important role with aircraft survival equipment in relation to aircraft survival.

The simulation display unit 210 simulates the radar indicator of the aircraft on which the aircraft survival equipment is mounted. Through this, it is possible to verify whether the radar indicator of the aircraft works properly in conjunction with the aircraft survival equipment and the display performance of the radar indicator.

Correspondence analysis unit 230 analyzes the operation of the aircraft survival equipment. As a means to achieve the original purpose of the monitoring unit may include a display for displaying the analysis data to the verifier. Correspondence analysis unit 230 extracts / analyzes the information of the threats simulated by the threat simulation unit, the distance between the simulated threats and the aircraft survival equipment, and the operation state of each element of the aircraft survival equipment with respect to the received simulation signal, and displays the display means. Can be displayed via

In the above, the threat simulation unit 100 and the monitoring unit 200 has been described how to reliably verify the aircraft survival equipment in a limited space, the following is a method for verification in a similar situation on the battlefield more Let's look at.

There is a big difference between the situation of aircraft survival equipment of an aircraft in operation and the situation of aircraft survival equipment of a limited space such as a room. Aircraft survival equipment operating on the battlefield may be threatened by various threats at the same time, and the detection status of the threat detector may change depending on the aircraft's operational status and terrain. In addition, signals from chaff or flares fired from the corresponding equipment may be mixed with threat signals. In order to implement various and complex situations in a limited space, the aircraft survival equipment verification apparatus may further include a scenario application unit 300.

The scenario application unit 300 generates and reproduces a scenario applied to the aircraft on which the aircraft survival equipment is mounted, and drives the threat simulation unit in response to the threat included in the scenario.

In the scenario, the terrain, the route / speed of the aircraft, and the threat placed at a certain position among the terrain are defined. Creating and replaying such a scenario can simulate a situation in which an aircraft equipped with a verification target aircraft survival equipment is operated on a predetermined terrain and threatened by a threat at a predetermined position. The consideration here is that the threat detector may not normally receive the threat signal, depending on the aircraft's operating conditions and terrain. The threat detector has its own error, which is complex with the aircraft's operating conditions and terrain, limiting the normal reception of normal threat signals. In addition, the reception of threat signals may also be limited by chaff or flare fired from the corresponding equipment. Therefore, in order to implement the limitation of the threat detector, the scenario includes error information of the threat detector, operation state information of the aircraft (including driving state of the corresponding equipment in some cases), and terrain information. Even the limits of threat detectors can be implemented through scenarios, enabling verification in more realistic situations.

The scenario application unit may define the state of the threat deceived by the driven response equipment when the response equipment is driven from the aircraft survival equipment. To this end, the scenario application unit should receive at least the type of response equipment driven or driven from the aircraft survival equipment.

On the other hand, the aircraft actually operated may provide a means for mitigating the limitation of the operation of the aircraft survival equipment due to the limitation of the threat detector described above. For example, when the navigation information is integrated by integrating the aircraft operation status information (e.g., the fuselage angle which varies according to the stop, go straight, and the turn in the helicopter) and the terrain information, the navigation information is used by the mission computer that controls and manages the entire aircraft. Therefore, the restriction of the threat detector can be relaxed by changing the direction of the threat detector or changing the processing method / analysis method of the signal detected by the threat detector.

Thus, for the purpose of simulating a more realistic situation, the monitoring unit may include a mission computer simulation unit 250 that simulates at least a module related to the aircraft survival equipment in the mission computer of the aircraft equipped with the aircraft survival equipment. At this time, the mission computer simulation unit 250 controls the aircraft survival equipment according to the navigation information of the aircraft included in the scenario. The reason why the mission computer simulation unit was formed integrally with the monitoring unit is that the function of monitoring the status of the aircraft survival equipment (the situation where control results are transmitted from the aircraft survival equipment) is similar to that of the monitoring unit during the operation of the mission computer in the aircraft. to be. As a result, when the monitoring unit and the mission computer simulation unit are integrally formed, some functions of the mission computer are verified.

On the other hand, if the verification of the task computer is not considered, the task computer simulation may be excluded and the function may be included in the scenario application unit.

At this time, the scenario application unit generates and reproduces a scenario applied to the aircraft equipped with the aircraft survival equipment, drives the threat simulator in response to the threat included in the scenario, and operates the aircraft survival equipment according to the navigation information of the aircraft included in the scenario. Control. Although the verification of the mission computer simulation is not performed, the inconvenience of setting up the mission computer simulation can be reduced because the configuration of the mission computer simulation can be performed together with the scenario generation.

On the other hand, the scenario application unit may further include a corresponding information display unit (not shown) for displaying the correspondence between the scenario and the monitored aircraft survival equipment. In this case, the corresponding information display unit may be integrally formed with the scenario application unit or the monitoring unit. Since the scenario application unit includes an input means for defining various types of information and a display for confirming the input contents, the display may be used as a display means of the corresponding information display unit. Similarly, since the monitoring unit is provided with a display for monitoring and displaying the response of the aircraft survival equipment, the display can be used as a display means of the corresponding information display unit.

Looking at it, the terrain defined in the scenario, the path of the aircraft (helix), various threats such as missiles, lasers, and radars are displayed, and the location / range of the chaff / flare fired from the aircraft survival equipment in response to the threats It is displayed together. The Stimulator radiation on the right represents the threat signal being simulated by the threat simulator.

4 is a flowchart illustrating a method for verifying aircraft survival equipment related to the present invention.

The aircraft survival equipment verification method shown in FIG. 4 may be described as the operation of the aircraft survival equipment verification apparatus shown in FIG. 1.

First, a scenario including the operation of an aircraft equipped with aircraft survival equipment and terrain and threat information related to the operation of the aircraft is generated (S 710). As the operation performed by the scenario applying unit, the scenario applying unit may include a database in which various kinds of information necessary for generating a scenario are stored. The terrain defined in the scenario may be virtual terrain information or actual terrain information. The scenario application unit includes a menu for creating a terrain, a menu for selecting a created terrain, a menu for placing a threat at a predetermined position on the created or selected terrain, a menu for selecting an aircraft capable of mounting the aircraft survival equipment to be verified, and a selected menu. It may include a menu for setting the path / speed of the aircraft.

Next, the generated scenario is reproduced (S 720). When the response device of the aircraft survival equipment is driven during the reproduction by the operation of the scenario application unit, the response state of the threatening device and the response of the threatened device may be newly defined. In addition, when a threat is defined that targets the aircraft in simulation during scenario reproduction, the threat simulation unit is controlled to simulate the threat signal.

Next, a signal of a threat object that targets the aircraft in the reproduced scenario is simulated (S 730). When there is no scenario application unit as an operation performed by the threat simulation unit, the operation may be controlled by the monitoring unit, or may be driven without the control of the monitoring unit, and the driving result may be transmitted to the monitoring unit.

The response of the aircraft survival equipment in response to the simulated signal is monitored (S740). At this time, the display of the monitored information may be performed through the monitoring unit or the corresponding information display unit.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
