The influence of the leakage clearance on the wave rotor ignition can be explored by fine tuning the platform control clearance. Chinese patent publication No. CN104458269A proposes a simplified internal combustion wave rotor experimental apparatus based on relative motion, in which a sealing disk is connected to a rotating shaft to realize relative motion of a dual-channel wave rotor, so as to avoid the problem of data acquisition caused by channel rotation.
However, when the internal combustion wave rotor is tested, the problem which cannot be solved is how to observe and measure the ignition and combustion process of the gas in the wave rotor channel.

Due to the two aspects, the observation and measurement of multiple physical fields such as flow, chemical reaction and the like in the wave rotor channel become difficult during the working process of the internal combustion wave rotor.

Detailed Description
For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
The structure, proportion, size and the like shown in the drawings are only used for matching with the content disclosed in the specification, so that the person skilled in the art can understand and read the description, and the description is not used for limiting the limit condition of the implementation of the invention, so the method has no technical essence, and any structural modification, proportion relation change or size adjustment still falls within the scope of the technical content disclosed by the invention without affecting the effect and the achievable purpose of the invention. In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
In the related art, when the ignition and combustion process of the gas in the wave rotor channel of the internal combustion wave rotor are experimentally studied, the wave rotor channel made of a metal material is generally adopted. The reason for this is that:
firstly, the temperature of the wave rotor channel is very high in the ignition and combustion processes of the gas in the wave rotor channel, and the channel made of common materials is difficult to bear the high temperature generated in the ignition and combustion processes of the gas;
secondly, the internal combustion wave rotor has higher rotating speed in the experimental process, and the torque transmission between the wave rotor and the rotating shaft and between the wave rotor and the end plate of the wave rotor mainly depends on the wave rotor channel for transmission;
finally, in order to facilitate the observation and detection of the gas in the wave rotor channel in the ignition and combustion processes, the arrangement of the quartz observation port on the side wall of the wave rotor channel is convenient.
However, in practical research, since the internal combustion wave rotor is in a high-speed rotation state, the side wall of the wave rotor channel is very easy to shield the observation port, so that it is difficult for a measurement unit such as a high-speed camera to acquire ignition information and combustion information of gas. Acceptable improvement methods include arranging a plurality of high-speed cameras or the like in the circumferential direction of the internal combustion wave rotor, but are too costly.
To solve the above problem, the present embodiment provides an internal combustion wave rotor 100. Referring to fig. 1 and 2, the internal combustion wave rotor 100 of the present embodiment includes a first end plate 110, a second end plate 120, a wave rotor channel 130, and a force transfer member 140.
The first end plate 110 and the second end plate 120 are symmetrically arranged, the wave rotor channel 130 is located between the first end plate 110 and the second end plate 120, one end of the wave rotor channel 130 is connected with the first end plate 110, the other end of the wave rotor channel 130 is connected with the second end plate 120, and the force transmission member 140 is connected between the first end plate 110 and the second end plate 120 and used for transmitting torque between the first end plate 110 and the second end plate 120.
The wave rotor channel 130 is a visual structure, that is, the wave rotor channel 130 is a transparent structure, or at least a semitransparent structure, so that a measurement unit such as a high-speed camera located outside the wave rotor channel 130 can acquire gas ignition information and combustion information in the wave rotor channel 130 through a side wall of the wave rotor channel 130. Specifically, the wave rotator channel 130 may be made of quartz material, or other transparent material that is resistant to high temperature.
Fig. 3 shows the structure of the first end plate 110 in the present embodiment. Specifically, the first end plate 110 may be provided with a plurality of first fixing grooves 112 along a circumferential direction, and the first fixing grooves 112 are used for fixing an end portion of the wave rotor channel 130. The shape of the first fixing groove 112 is the same as the shape of the end of the wave rotator channel 130, and may be a fan-shaped structure or a fan-like structure. The number of the first fixing grooves 112 is even, and the even number of the first fixing grooves 112 may be equidistantly distributed in the circumferential direction of the first end plate 110, so that the number of the wave rotor passages 130 is also set to be even and equidistantly distributed in the circumferential direction of the one end plate 110 during the experiment, thereby ensuring that the internal combustion wave rotor 100 keeps balance when rotating at a high speed and preventing the internal combustion wave rotor 100 from shaking during the rotation to affect the collection of the ignition information and the combustion information by the measuring unit.
In addition, the first air flow channel 111 may be opened in the groove of the first fixing groove 112, and the first air flow channel 111 may be disposed to penetrate the first end plate 110, so that after the end of the wave rotor channel 130 is mounted on the first fixing groove 112, air may be introduced into/discharged from the wave rotor channel 130 through the first air flow channel 111.
As a further optimization, the size of the first fixing groove 112 may be set slightly larger than the size of the outer sidewall of the wave rotor channel 130, and thus when the wave rotor channel 130 is inserted into the first fixing groove 112, i.e., the first fixing groove 112 is in an operating state, the sealing gasket 132 may be provided at the first fixing groove 112. The gasket 132 may be fitted over the wave rotator channel 130, and the gasket 132 may be located between the outer sidewall of the wave rotator channel 130 and the groove wall of the first fixing groove 112. The sealing pad 132 may be made of an elastic material, such as a rubber material, or a silicone material, so that when the sealing pad 132 is disposed between the outer sidewall of the wave rotor channel 130 and the groove wall of the first fixing groove 112, the groove wall of the first fixing groove 112 forces the sealing pad 132 to be compressed centripetally, thereby pressing against the outer sidewall of the wave rotor channel 130 to seal the gap between the first fixing groove 112 and the wave rotor channel 130.
As a further optimization, when the wave rotor passage 130 is not inserted in the first fixing groove 112, that is, when the first fixing groove 112 is in a rest state, the first air flow passage 111 on the first fixing groove 112 may be closed by the end cover 131. Specifically, the end cap 131 is detachably connected to the first fixing groove 112, for example, by a bolt. A plurality of bolt connecting holes can be formed in the bottom of the first fixing groove 112, through holes can be formed in the end cover 131 at positions corresponding to the bolt connecting holes, and the end cover 131 is connected with the first fixing groove 112 by means of threaded matching of the connecting bolts and the bolt connecting holes after the connecting bolts penetrate through the through holes.
Fig. 4 shows the structure of the second end plate 120. Specifically, the second end plate 120 may be provided with a plurality of second fixing grooves 122 along a circumferential direction, and the second fixing grooves 122 are used for fixing ends of the wave rotor channel 130. The second fixing groove 122 may have a fan-shaped structure or a fan-like structure, which is the same as the shape of the end of the wave rotor passage 130. The position of the second fixing groove 122 on the second end plate 120 corresponds to the position of the first fixing groove 112 on the first end plate 110. The number of the second fixing grooves 122 may be the same as the number of the first fixing grooves 112.
In addition, a second air flow channel 121 may be further opened in the groove body of the second fixing groove 122, and the second air flow channel 121 is disposed to penetrate the second end plate 120, so that after the end of the wave rotor channel 130 is mounted on the second fixing groove 122, air may be introduced into/discharged from the wave rotor channel 130 through the second air flow channel 121. Of course, when the first gas flow channel 111 is used to introduce gas into the wave rotor channel 130, the second gas flow channel 121 may be used to exhaust gas from the wave rotor channel 130.
As a further optimization, the size of the second fixing groove 122 may be set slightly larger than the size of the outer sidewall of the wave rotor channel 130, and thus when the wave rotor channel 130 is inserted into the second fixing groove 122, i.e., the second fixing groove 122 is in an operating state, the sealing gasket 132 may be provided at the second fixing groove 122. The packing 132 may be fitted over the wave rotator channel 130, and the packing 132 may be located between an outer sidewall of the wave rotator channel 130 and a groove wall of the second fixing groove 122. The sealing pad 132 may be made of an elastic material, such as a rubber material, or a silicone material, so that when the sealing pad 132 is disposed between the outer sidewall of the wave rotor channel 130 and the groove wall of the second fixing groove 122, the groove wall of the second fixing groove 122 forces the sealing pad 132 to be compressed centripetally, so as to press against the outer sidewall of the wave rotor channel 130, thereby sealing the gap between the second fixing groove 122 and the wave rotor channel 130.
As a further optimization, when the wave rotor passage 130 is not inserted in the second fixing groove 122, that is, when the second fixing groove 122 is in a rest state, the second air flow passage 121 on the second fixing groove 122 may be closed by the end cover 131. Specifically, the end cap 131 is detachably connected to the second fixing groove 122, for example, by bolts. A plurality of bolt connecting holes can be formed in the bottom of the second fixing groove 122, through holes can be formed in the end cover 131 at positions corresponding to the bolt connecting holes, and the end cover 131 is connected with the second fixing groove 122 by means of threaded matching of the connecting bolts and the bolt connecting holes after the connecting bolts penetrate through the through holes.
Fig. 5 shows the structure of the force transfer member 140. Specifically, the force-transmitting member 140 includes two mounting plates 144, and the two mounting plates 144 are symmetrically disposed. A plurality of dowel bars 142 are disposed between the two mounting plates 144.
The end of the dowel bar 142 may protrude from the mounting plate 144, for example, a through hole may be formed in the mounting plate 144, and then the end of the dowel bar 142 may pass through the through hole and protrude from the outer side surface of the mounting plate 144. In order to connect the dowel bar 142 with the first end plate 110 and the second end plate 120, a first fixing hole 113 may be formed in the first end plate 110, a second fixing hole 123 may be formed in the second end plate 120 at a position corresponding to the first fixing hole 113, and two ends of the dowel bar 142 may be inserted into the first fixing hole 113 and the second fixing hole 123 at corresponding positions, respectively.
To ensure the stability of the force transfer member 140 in the moment transmission between the first end plate 110 and the second end plate 120, the number of the force transfer rods 142 is preferably three or more, and the three or more force transfer rods 142 may be equally spaced around the circumference of the mounting plate 144.
As a further optimization, in order to enhance the stability of the connection between the force-transmitting member 140 and the first end plate 110 and the second end plate 120, a plurality of third connecting holes 141 may be formed in the mounting plate 144, and at the same time, the first connecting hole 114 is formed in the first end plate 110 at a position corresponding to the third connecting holes 141, and the second connecting hole 124 is formed in the second end plate 120 at a position corresponding to the third connecting holes 141.
When the force transmission member 140 is installed on the first end plate 110 and the second end plate 120, the force transmission member 140 can be connected to the first end plate 110 by using the connecting bolt to pass through the third connecting hole 141 and connect to the first connecting hole 114, and the force transmission member 140 can be connected to the second end plate 120 by using the connecting bolt to pass through the third connecting hole 141 and connect to the second connecting hole 124, so as to complete the fixed connection between the first end plate 110 and the second end plate 120.
