Description

Technical Field

[0001] The invention belongs to the technical field of missile flight trajectory control, and in particular relates to a plug-in type flight trajectory control device. Background Art

[0002] In the wars that have occurred in recent years, aircraft and missiles of various countries have become mainstream weapons and equipment. Today's aircraft and missiles mostly use wing guidance, side gunpowder gas injection guidance or nozzle displacement guidance. Among them, wing guidance and side gunpowder gas injection guidance are both external to the warhead, resulting in problems such as increased warhead volume, single launch method, and increased transportation and storage costs. The nozzle displacement guidance has extremely high requirements for the gunpowder of the propulsion engine and will only work when the gunpowder burns. According to the needs of current and future wars and battlefields, it is necessary to design a plug-in flight trajectory control device that is low-priced, small in size, easy to transport and store, and has no extremely high requirements for the gunpowder of the propulsion engine.

[0023] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0024] This embodiment provides a plug-in type flight trajectory control device, the structure of which is as follows: Figure 1 and 2 As shown, it mainly includes a plug-in plate motion actuator 1, a plug-in plate 2 and a mounting shell 3.

[0025] The mounting housing 3 is mounted on any equipment that needs to control the flight trajectory, and four plug-in board motion actuators 1 are fixedly mounted inside the mounting housing 3 by screws, and four plug-in boards 2 are connected to the corresponding plug-in board motion actuators 1 and extend outward from the inside of the mounting housing 3. The plug-in board motion actuator 1 has an electrically controlled rotational motion function, and can control the extension amount of the corresponding plug-in board 2, so that the plug-in board 2 has the function of blocking the airflow, and controls the flight trajectory of the equipment through different extension amounts.

[0026] like Figure 3 As shown, a center plate is processed inside the mounting housing 3, and the center plate has a cross-shaped structure. Each end is processed with a plug-in plate slide 32 that is connected to the outer wall of the mounting housing 3 and is perpendicular to the axis of the mounting housing 3. The two opposing plug-in plate slides 32 are in the form of through holes, and the two through holes are in different planes to avoid mutual interference when the plug-in plates 2 are retracted. Two motor seats 33 and two rotating rod guide grooves 31 are processed on both sides of the center plate, and the rotating rod guide grooves 31 are connected to the plug-in plate slide 32.

[0027] like Figure 4 As shown, the plug-in motion actuator 1 includes a rotating rod 11, a rotating motor 12 and a motor fixing plate 13. The motor fixing plate 13 is mounted on the motor seat 33 of the mounting housing 3 by screws, the rotating motor 12 is mounted in the motor mounting hole of the motor fixing plate 13 and connected to the motor seat 33, and the rotating rod 11 is mounted on the output end of the rotating motor 12 by screws, and the rotating motor 12 drives the rotating rod 11 to rotate. The rotating rod 11 is inserted into the rotating rod guide groove 31 and then into the rotating rod slide groove 22, and the rotating rod guide groove 31 provides rotation limit.

[0028] like Figure 5As shown, the plug board 2 has a main body 21, and a rotating rod slot 22 is processed at the lower part of the main body 21. The rear end of the main body 21 is inserted into the plug board slot 32 of the mounting shell 3, and the front end of the rotating rod 11 is inserted into the rotating rod slot 22. The rotation of the rotating rod 11 drives the main body 21 to extend or retract in the plug board slot 32.

[0029] The working principle of the plug-in type flight trajectory control device of the present invention is as follows:

[0030] The plug-in board type flight trajectory control device is installed on any equipment that needs flight trajectory control, and the plug-in board motion actuator 1 is installed on the motor seat 33 of the mounting housing 3 and fixed with the motor fixing plate 13. During the flight of the aircraft, when the flight trajectory needs to be changed, the rotating motor 12 of the plug-in board motion actuator 1 is controlled to rotate, and the rotating rod 11 is controlled to rotate. The rotating rod 11 pushes the plug-in board 2 to slide in the plug-in board slot 32 through the rotating rod slot 22 and extend out of the mounting housing 3. Since the plug-in board 2 extends out of the housing, the air resistance on one side of the equipment increases, thereby changing the flight trajectory of the flight equipment. According to the length of the plug-in board 2 extending out, the size of the steering can be changed, and the purpose of high-precision control of the flight trajectory is achieved.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
