[0002] An ejection seat uses a power unit under the seat to eject the pilot from the cockpit in the event of an aircraft crash, and then deploys a parachute to bring the pilot to a safe landing, thus saving the pilot's life.
[0003] For ejection seats in two-seat side-by-side aircraft, in order to avoid collisions that may occur during simultaneous launch, side-by-side ejection seats need to be launched sequentially, and reasonable timing control is required to prevent the former from interfering with the latter.
[0004] Therefore, in order to realize the seat ejection control of two-seat side-by-side aircraft occupants, a side-by-side ejection control system is needed. Summary of the Invention

[0007] The ejection seat includes a first ejection seat and a second ejection seat, and when either the first ejection seat generates an ejection signal, it can transmit the signal to the other ejection seat.
[0008] The ejection cover device includes a first ejection cover device, a second ejection cover device, and a pressure relief port cutting device. The first and second ejection cover devices are used to cut the top structure of the cockpit on the corresponding side to form an ejection port cover, and the pressure relief port cutting device is used to cut the top structure of the cockpit to form a pressure relief port.
[0009] The detonation command system includes an AND gate controller, a one-way detonation connector, and a timer. The first ejection seat and the first ejection cover device are connected by the AND gate controller, the one-way detonation connector, and the timer to form an ejection start signal and ejection cover cutting signal circuit for the first ejection seat. The second ejection seat and the second ejection cover device are connected by the AND gate controller and the one-way detonation connector to form an ejection start signal and ejection cover cutting signal circuit for the second ejection seat. The one-way detonation connector in the second ejection seat is connected to the pressure relief port cutting device.
[0010] Furthermore, the first ejection seat and the second ejection seat are arranged side by side in the aircraft cockpit for ejecting the occupants from the cockpit in emergency situations. Both the first ejection seat and the second ejection seat have ejection dispersion functions, and the dispersion directions of the first ejection seat and the second ejection seat are opposite during ejection.
[0011] Furthermore, the first ejection seat and the second ejection seat have a delay device inside for generating a delay t0.
[0012] Furthermore, the delay devices provided inside the first and second cap-throwing devices are used to generate a delay t1.

The ejection activation signal is also output through the right ejection seat to the AND gate controller and one-way detonation connector of the ejection seat detonation command system and transmitted to the right ejection cover device and the depressurization port cutting device. The depressurization port cutting device cuts the top structure of the cockpit to form a depressurization port for depressurization of the cockpit.
[0018] After a delay of t1 inside the right ejection cover device, the right ejection cover device cuts the top of the cockpit to form the right ejection port cover and ejects it. At the same time, it generates a right ejection port cover cutting feedback signal to the door controller of the corresponding ejection seat detonation command system. The door controller performs a logical AND judgment on the ejection start signal and the right ejection port cover cutting feedback signal. When both signals are input, the door controller outputs a clearing feedback signal to the right ejection seat. The right ejection seat ejects the passenger out of the cockpit after a delay of t0 inside.
[0019] After a delay of t2, the ejection start signal is transmitted to the left ejection cover device. The left ejection cover device operates internally after a delay of t1, cutting and forming the left ejection hatch cover on the top of the cockpit and ejecting it. At the same time, a left ejection hatch cover cutting feedback signal is generated and sent to the AND gate controller of the corresponding ejection seat protection command system. The AND gate controller performs a logical AND judgment on the ejection start signal and the left ejection hatch cover cutting feedback signal. When both signals are input, the AND gate controller outputs a clearing feedback signal to the left ejection seat. After a delay of t0 inside the left ejection seat, the ejector is ejected from the cockpit.
[0020] 2) When the right ejection seat is activated, the ejection activation signal is output to the AND gate controller and one-way detonation connector of the ejection seat detonation command system and then transmitted to the right ejection cover device and the depressurization port cutting device. The ejection activation signal is transmitted through the left ejection seat to the AND gate controller and one-way detonation connector of the detonation command system of the left ejection seat and then to the timer. The depressurization port cutting device cuts the top structure of the cockpit to form a depressurization port for depressurization of the cockpit.
[0021] After a delay of t1 inside the right ejection cover device, the right ejection cover device cuts the top of the cockpit to form the right ejection port cover and ejects it. At the same time, it generates a right ejection port cover cutting feedback signal to the AND gate controller of the ejection seat detonation command system. The AND gate controller performs a logical AND judgment on the ejection start signal and the right ejection port cover cutting feedback signal. When both signals are input, the AND gate controller outputs a clearing feedback signal to the right ejection seat. After a delay of t0 inside the right ejection seat, the ejector is ejected from the cockpit.
[0022] After a delay of t2, the ejection start signal is transmitted to the left ejection cover device. The left ejection cover device operates internally after a delay of t1, cutting and forming the left ejection port cover on the top of the cockpit and ejecting it. At the same time, a left ejection port cover cutting feedback signal is generated and sent to the AND gate controller of the left ejection seat detonation command system. The AND gate controller performs a logical AND judgment on the ejection start signal and the left ejection port cover cutting feedback signal. When both signals are input, the AND gate controller outputs a clearing feedback signal to the left ejection seat. After a delay of t0 inside the left ejection seat, the ejector exits the cockpit.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings.
[0041] like Figure 1 As shown, the side-by-side ejection detonation system provided in this application includes an ejection seat 10, a cover ejection device 20, and a detonation command system 30.
[0042] The ejection seat 10 includes a first ejection seat 11 and a second ejection seat 12, which are arranged side-by-side in the aircraft cockpit for ejecting occupants from the cockpit in emergency situations. Both the first ejection seat 11 and the second ejection seat 12 have ejection dispersion functions; during ejection, the first ejection seat 11 disperses in a first direction, and the second ejection seat 12 disperses in a second direction. When either ejection seat generates an ejection signal, it can be transmitted to the other ejection seat. Furthermore, both the first ejection seat 11 and the second ejection seat 12 are equipped with controllers to generate a delay t0.
[0043] The ejection port device 20 is installed on the top of the cockpit and includes a first ejection port device 21, a second ejection port device 22, and a pressure relief port cutting device 23. The first and second ejection port devices 21 and 22 are used to cut the corresponding top structures of the cockpit to form ejection port covers, and the pressure relief port cutting device 23 is used to cut the top structures of the cockpit to form pressure relief port covers. After receiving the detonation signal, the first and second ejection port devices 21 and 22 operate for a delay t1, and output ejection port cover cutting feedback signals after completing the ejection port cover cutting and ejection. The delay t1 is controlled by a controller installed inside the first and second ejection port devices 21 and 22.
[0044] The detonation command system 30 includes a first ejection seat detonation command system and a second ejection seat detonation command system. The first detonation command system includes an AND gate controller 31, a one-way detonation connector 32, and a timer 34. The second detonation command system includes an AND gate controller 31, a one-way detonation connector 32, and a timer 34.
[0045] Specifically, for the first ejection seat detonation command system, the input end of the AND gate controller 31 is connected to the first ejection device 21 and the output end of the one-way detonation connector 32. The output end of the AND gate controller 31 and the input end of the one-way detonation connector 32 are connected to the first ejection seat 11. The output end of the one-way detonation connector 32 is connected to the first ejection device 21 through the delay timer 34.
[0046] Similarly, for the second ejection seat detonation command system, the input terminal of the gate controller 31 is connected to the second ejection cover device 22 and the output terminal of the one-way detonation connector 32, and the output terminal of the gate controller 31 and the input terminal of the one-way detonation connector 32 are connected to the second ejection seat 12. The output terminal of the one-way detonation connector 32 is connected to the second ejection cover device 22, the pressure relief port cutting device 23, and the one-way detonation connector 32 output terminal of the first ejection seat detonation command system, respectively.
[0047] The aforementioned multi-component connections can be achieved using a three-way connector 33 and / or a four-way connector 35. The gate controller 31 is installed on the lower beam of the slide rail of the corresponding ejection seat. It receives the ejection start signal and ejection port cover cutting feedback signal from the corresponding ejection seat, performs a logical AND judgment, and outputs a corresponding channel cleaning feedback signal to the corresponding ejection seat. The timer 34 is used to generate a delay t2.
[0048] In the preferred embodiment of this application, the detonating cord connects the timer 34, the four-way connector 35, the three-way connector 33, the AND gate controller 31, the one-way detonation connector 32, the first throw-out device 21, the second throw-out device 22, and the pressure relief port cutting device 23. The detonating cord transmits signals through the detonation wave as a medium.
[0049] In addition, this application also provides a control method for the above-mentioned side-by-side catapult detonation system, the method comprising the following steps:
[0050] 1) When the first ejection seat 11 is activated, the ejection activation signal is output to the AND gate controller 31 and the one-way detonation connector 32 of the ejection seat detonation command system. The signal is transmitted to the delay unit 34 via the three-way connector 33. The ejection activation signal is also output through the second ejection seat 12 to the AND gate controller 33 and the one-way detonation connector 32 of the ejection seat detonation command system. The signal is transmitted to the second ejection cover device 22 and the pressure relief port cutting device 23 via the three-way connector 33 and the four-way connector 35. The pressure relief port cutting device 23 cuts the top structure of the cockpit to form a pressure relief port for cockpit pressure relief.
[0051] After a delay of t1 = 0.15s inside the second ejection device 22, the second ejection device 22 cuts the top of the cockpit to form the second ejection port cover and ejects it. At the same time, it generates a second ejection port cover cutting feedback signal to the door controller 31 of the corresponding ejection seat detonation command system. The door controller 31 performs a logical AND judgment on the ejection start signal and the second ejection port cover cutting feedback signal. When both signals are input, the door controller 31 outputs a channel clearing feedback signal to the second ejection seat 12. The second ejection seat 12 ejects out of the cockpit after a delay of t0 = 0.15s inside.
[0052] After a delay of t2 = 0.4s, the ejection start signal is transmitted to the first ejection cover device 21. The first ejection cover device 21 operates with a delay of t1 = 0.15s, cutting and forming the first ejection port cover on the top of the cockpit and ejecting it. At the same time, a first ejection port cover cutting feedback signal is generated and sent to the AND gate controller 31 of the corresponding ejection seat protection command system. The AND gate controller 31 performs a logical AND judgment on the ejection start signal and the first ejection port cover cutting feedback signal. When both signals are input, the AND gate controller 31 outputs a channel clearing feedback signal to the first ejection seat 11. After a delay of t0 = 0.15s, the ejector exits the cockpit.
[0053] 2) When the second ejection seat initiates the ejection process, the working sequence is the same as that of the first ejection seat, that is:
[0054] When the second ejection seat 12 is activated, it outputs an ejection activation signal to the AND gate controller 31 and the one-way detonation connector 32 of the ejection seat detonation command system. The signal is transmitted to the second ejection cover device 22 and the pressure relief port cutting device 23 via the T-connector 33 and the four-way connector 35. The ejection activation signal is also transmitted through the first ejection seat 11 to the AND gate controller 31 and the one-way detonation connector 32 of the first ejection seat detonation command system. The signal is transmitted to the delay device 34 via the T-connector 33. The pressure relief port cutting device 23 cuts the top structure of the cockpit to form a pressure relief port for cockpit depressurization.
[0055] After a delay of t1 = 0.15s inside the second ejection device 22, the second ejection device 22 cuts the top of the cockpit to form the second ejection port cover and ejects it. At the same time, it generates a second ejection port cover cutting feedback signal to the AND gate controller 31 of the ejection seat detonation command system. The AND gate controller 31 performs a logical AND judgment on the ejection start signal and the second ejection port cover cutting feedback signal. When both signals are input, the AND gate controller 31 outputs a channel clearing feedback signal to the second ejection seat 12. The second ejection seat 12 ejects out of the cockpit after a delay of t0 = 0.15s inside.
[0056] After a delay of t2 = 0.4s, the ejection start signal is transmitted to the first ejection cover device 21. The first ejection cover device 21 operates with a delay of t1 = 0.15s, cutting and forming the first ejection port cover on the top of the cockpit and ejecting it. At the same time, a first ejection port cover cutting feedback signal is generated and sent to the AND gate controller 31 of the first ejection seat detonation command system. The AND gate controller 31 performs a logical AND judgment on the ejection start signal and the first ejection port cover cutting feedback signal. When both signals are input, the AND gate controller 31 outputs a channel clearing feedback signal to the first ejection seat 11. After a delay of t0 = 0.15s, the ejector exits the cockpit.
[0057] The side-by-side ejection detonation system provided in this application can activate either the first ejection seat 11 or the second ejection seat 12, and both can be launched in a fixed order, i.e., the second ejection seat first, then the first ejection seat. When it is necessary to achieve a fixed launch order of the ejection seats, i.e. the first ejection seat first, then the second ejection seat, the first and second ejection seats and their corresponding ejection cover devices and detonation command systems in the above embodiments can be modified accordingly.
[0058] The side-by-side ejection detonation system and its control method of this application can realize ejection rescue in emergency ejection conditions of aircraft, and have a simple structure, high reliability and are easy to implement.
[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
