Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of total temperature probe, in particular to a total temperature probe with high-efficiency particle carrying-out structure and a flow channel optimization method thereof. BACKGROUND

[0002] The total temperature probe is a device for measuring the total temperature of the atmosphere on an airplane, and its accurate and efficient measurement is of great significance to the flight control system. The existing total temperature probe is mostly a stagnation probe, whose principle is to reduce the flow rate of the airflow entering the flow channel of the probe, so that the airflow is stagnated, and then the temperature of the stagnated air is measured. However, due to the complex environment of the probe, the air entering the flow channel contains water droplets, ice, ice crystals or dust particles, and if these particles cannot be timely discharged from the inner flow channel, it will lead to inaccurate or invalid total temperature measurement, thereby affecting flight safety. SUMMARY

[0003] In view of the above problems in the prior art, the present application provides a total temperature probe with high-efficiency particle carrying-out structure and a flow channel optimization method thereof, which solves the problem of affecting the measurement accuracy of the existing total temperature probe due to the inability to timely discharge particles.

[0004] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0005] On the one hand, a total temperature probe with high-efficiency particle carrying-out structure is provided, which comprises: a support shell, the inside of the support shell is fixed with a total temperature sensitive element for measuring total temperature; a socket is fixed at the bottom of the support shell through a flange and is in conduction with the bottom of the total temperature sensitive element; a head shell is fixed at the top of the support shell, the inside of the head shell is provided with a throat, a concave channel and a swept-back sensitive channel located at the bottom between the throat and the concave channel, the larger opening end of the throat is a circular air inlet, the smaller opening end of the throat is in communication with one end of the swept-back sensitive channel and the concave channel respectively, and the bottom end of the swept-back sensitive channel is in communication with the total temperature sensitive element; the concave channel is in the shape of a circular truncated cone and the inner wall is curved, the diameter of the large-diameter end of the concave channel is larger than that of the smaller opening end of the throat, and a straight outlet is provided on the small-diameter end of the concave channel.

[0006] The working principle of the scheme is that air enters the throat from the circular air inlet, the throat is arranged to realize the process of compression and expansion of the air entering the total temperature probe, to ensure that the airflow has a large speed after passing through the separation bend of the sweep angle sensitive channel, so that the particles have strong airflow inertia. After the air passes through the throat, it collides with the upper and lower concave surfaces of the concave channel and shrinks, the concave channel is arranged to expand and shrink, so that the particles in the flow direction are ejected in the straight outlet direction after collision, and are guided out by the inertia of the airflow, so that the particles do not have the condition to enter the rear sweep angle sensitive channel, so that the air entering the rear sweep angle sensitive channel is basically free of particles, and the measurement accuracy of the total temperature sensitive element is improved.

[0007] Further, the curved inner wall of the concave channel includes an upper concave surface and a lower concave surface, both of which are curved surfaces, the upper concave surface is tangent to the connection of the throat, and the upper curvature of the upper concave surface is greater than the lower curvature of the lower concave surface. The concave channel is optimized based on the technology of vortex control inertia force to eject particles, the curve of the upper concave surface is tangent to the tangent of the throat main channel, and the setting of the upper curvature being greater than the lower curvature makes it more difficult for sand ice and other particles to enter the rear sweep angle sensitive channel, and effectively reduces the vortex intensity of the upper concave surface, and improves the particle ejection efficiency.

[0008] Further, the horizontal angles of the large diameter end and the small diameter end of the upper concave surface are 9° and 19° respectively, and the horizontal angles of the large diameter end and the small diameter end of the lower concave surface are 26° and 34° respectively.

[0009] Further, the included angle between the entry slope of the throat and the horizontal flow is 28.7°.

[0010] Further, the top of the sweep angle sensitive channel is provided with a separation bend in communication with the throat and the concave channel respectively, and a plurality of adsorption holes are arranged on the entry slope of the throat, on both sides of the separation bend, and on the rear wall surface of the sweep angle sensitive channel. The arrangement of the adsorption holes reduces the boundary layer effect of the airflow, weakens the vortex intensity in the separation bend and the sweep angle sensitive channel, makes the airflow in the flow channel more smooth, reduces the formation of the vortex of the lower concave surface, and enhances the total temperature recovery coefficient.

[0011] Further, a circular exhaust channel in communication with the plurality of adsorption holes is arranged through the head shell at the entrance of the separation bend. The circular exhaust channel facilitates the collection and discharge of air in the plurality of adsorption holes, provides the flowability of the adsorption holes, and makes the adsorption holes better reduce the boundary layer effect of the airflow.

[0012] Further, the center lines of the straight outlet and the circular inlet are both coincident horizontal lines, and the area ratio of the inlet face of the circular inlet, the throat face of the throat, the concave curved face of the large diameter end of the concave channel, and the outlet face of the straight outlet is 9.5:3:7.3:1. Through the flow channel setting of first expansion, then reduction, then expansion, and finally reduction, the particulate matter first has strong airflow inertia, and then collides and shrinks, which facilitates the reduction of the influence of the particulate matter.

[0013] Further, the total temperature sensitive element comprises an inner heat insulation cylinder in which a temperature sensor is arranged, and an outer heat insulation cylinder arranged outside the inner heat insulation cylinder, and a rectifying crown for gas rectification is arranged at the upper end of the outer heat insulation cylinder.

[0014] Further, the bracket shell is arranged at an inclination of 85 degrees, a plurality of air outlet holes are arranged on the back surface of the bracket shell at the top of the total temperature sensitive element, and a plurality of air exhaust holes are arranged on the side surface of the bracket shell at the bottom of the total temperature sensitive element.

[0015] On the other hand, a flow channel optimization method of a total temperature probe with a high-efficiency particulate carrying-out structure is provided, comprising the following steps:

[0016] S1, x1, x2, x3, x4 and x5 are taken as optimization target independent variables, wherein x1, x2, x3, x4 and x5 are respectively the area of the circular inlet, the slope ratio of the throat, the area of the straight outlet, the sweepback angle of the sweepback sensitive channel, and the concave curved curvature of the concave channel;

[0017] S2, the evaluation indexes F1, F2 and F3 of the objective function are determined;

[0018]

[0019] Wherein, ΔT is the difference between the total temperature in the sweepback sensitive channel and the theoretical total temperature, r is the total temperature recovery coefficient, C is the ratio of the water content entering the sweepback sensitive channel to the water content of the circular inlet, A represents the area of the sweepback sensitive channel, unit m 2 ;T i represents the temperature of the grid point of the sweepback sensitive channel, unit K; T s represents the static temperature input by the boundary condition, T m represents the theoretical total temperature; m out represents the mass of liquid water entering the sweepback sensitive channel, m in represents the mass of liquid water entering the flow channel from the circular inlet.

[0020] S3, a flow channel design model in the total temperature probe is established according to the optimization target independent variables and the environmental boundary conditions;

[0021] S4, the solver of the CFD two-phase flow module is set through the initial boundary conditions.

[0022] S5, the value of the optimization target independent variable is constantly changed through the neural network model until F1=lim Ti Delta T similar to 0, F2=lim T R similar to 1, and F3=lim m C similar to 0, and the final optimization target independent variable value is taken as a design parameter of the internal flow channel of the total temperature probe.

[0023] When the three evaluation indexes F1, F2 and F3 satisfy the conditions at the same time, it indicates that the total temperature probe is in the most ideal measurement state. F1=0 indicates that there is no loss of total temperature, and the measured temperature is the total temperature. Since this is impossible from an engineering point of view, the measured value tends to 0. F2 is the total temperature recovery coefficient, that is, F2 is best to reach above 0.9999, different Mach numbers and attack angles will affect F2. F3=0 indicates that ice crystals and water droplets, etc. will not enter the swept-back angle sensitive channel, that is, the swept-back angle sensitive channel will not freeze, and the total temperature measurement accuracy will not be affected by particulate matter, and the specific difference between F1, F2, F3 and the target value can be adjusted according to the actual situation.

[0024] The application discloses a total temperature probe with a high-efficiency particle carrying-out structure and a flow channel optimization method thereof, and has the beneficial effects that:

[0025] 1. The throat, the concave channel and the swept-back angle sensitive channel are arranged, so that water droplets, ice, ice crystals and sand dust and other particulate matters contained in air are guided out from the straight outlet by using airflow inertia after entering the flow channel, the channel blockage caused by the particulate matter accumulation is prevented, the total temperature measurement accuracy and reliability are improved, and the flight safety of an airplane is improved.

[0026] 2. The suction holes of the throat inlet slope, the two sides of the separation bend and the swept-back angle sensitive channel improve the vortex generation of the airflow at the swept-back angle sensitive channel, increase the airflow resistance effect, and improve the temperature recovery coefficient of the total temperature probe.

[0027] 3. The concave channel is optimized based on the vortex control inertial force particle ejection technology, the upper concave curve and the tangent of the throat main channel are transitioned, the upper curvature is greater than the lower curvature, the angle makes it more difficult for sand / ice and other particulate matters to enter the swept-back angle sensitive channel, and the vortex intensity of the upper concave surface is effectively weakened, and the particle ejection efficiency is improved.

[0028] 4、The circular air inlet of the application is to maximize the inlet area, so as to increase the airflow into the probe; the middle section adopts the design of first contraction and then expansion of the throat, so that the airflow has greater flow rate and increases inertia; the rear section adopts the concave channel, so that the small vortex is formed at the reduced curvature of the upper concave surface, which increases the incident angle of the particle matter backward ejection, and reduces the influence on the shunt of the back sweep angle sensitive channel.

DETAILED DESCRIPTION

[0036] The specific embodiments of the application are described below to facilitate those skilled in the art to understand the application, but it should be clear that the application is not limited to the scope of the specific embodiments, and for those skilled in the art, it is obvious that various changes are within the spirit and scope of the application defined and determined by the appended claims, and all applications utilizing the concept of the application are within the scope of protection.

[0037] Example 1

[0038] Reference Figure 1 The embodiment provides a total temperature probe with high-efficiency particle carrying-out structure, which comprises a head shell 1, a support shell 2 and a socket 4.

[0039] Reference Figure 2The inside of the bracket shell 2 is fixed with a total temperature sensitive element for measuring total temperature, the bracket shell 2 is arranged at an angle of 85°, a plurality of air outlet holes 202 are arranged on the back of the bracket shell 2 at the top of the total temperature sensitive element, and a plurality of air exhaust holes 201 are arranged on the side of the bracket shell 2 at the bottom of the total temperature sensitive element.

[0040] The socket 4 is fixed at the bottom of the bracket shell 2 through the flange 3 and is in communication with the bottom of the total temperature sensitive element. The total temperature sensitive element comprises an inner heat insulation cylinder 7 with a temperature sensor 8 arranged inside, and an outer heat insulation cylinder 6 arranged outside the inner heat insulation cylinder 7, and the upper end of the outer heat insulation cylinder 6 is provided with a rectifier crown 5 for gas rectification.

[0041] The head shell 1 is fixed at the top of the bracket shell 2, and the inside of the head shell 1 is provided with a throat 102, a concave channel 105 and a sweptback angle sensitive channel 104 arranged in communication with each other at the bottom between the throat 102 and the concave channel 105, the larger opening end of the throat 102 is a circular air inlet 101, the smaller opening end of the throat 102 is in communication with one end of the sweptback angle sensitive channel 104 and the concave channel 105 respectively, and the bottom end of the sweptback angle sensitive channel 104 is in communication with the total temperature sensitive element; the concave channel 105 is in the shape of a circular truncated cone and the inner wall is curved, the diameter of the large diameter end of the concave channel 105 is larger than that of the smaller opening end of the throat 102, and a straight outlet 106 is arranged on the small diameter end of the concave channel 105.

[0042] The circular air inlet 101 maximizes the inlet area to increase the airflow into the probe; the middle section adopts a throat 102 design of first contraction and then expansion, so that the airflow has greater flow velocity and increases inertia; the rear section adopts a concave channel 105, so that the small vortex is formed at the reduced curvature of the upper concave surface 105a, which increases the incident angle of the particle matter ejected backward and reduces the influence on the flow division of the sweptback angle sensitive channel 104.

[0043] Specifically, the center lines of the straight outlet 106 and the circular air inlet 101 are both coincident horizontal lines. Referring to Figure 5 , the area ratio of the inlet face of the circular air inlet 101, the throat face of the throat 102, the concave curved face of the large diameter end of the concave channel 105 and the outlet face of the straight outlet 106 is 9.5:3:7.3:1. Through the flow channel setting of first expansion, then reduction, then expansion and finally reduction, the particle matter first has strong airflow inertia, and then collides and shrinks, which facilitates the reduction of the influence of the particle matter. Among them, Figure 5 The shapes of A, B, C and D in the figure are respectively the shapes of the inlet face of the circular air inlet 101, the throat face of the throat 102, the concave curved face of the large diameter end of the concave channel 105 and the outlet face of the straight outlet 106.

[0044] Specifically, as a specific structure of the concave channel 105, referring to Figure 2 andFigure 4 The inner curved wall of the concave channel 105 includes an upper concave surface 105a and a lower concave surface 105b, both of which are curved. The upper concave surface 105a is tangent to the connection with the throat 102, and the upper curvature of the upper concave surface 105a is greater than the lower curvature of the lower concave surface 105b. The concave channel 105 is optimized based on the technology of controlling inertial force to make particles pop out. The curve of the upper concave surface 105a is tangent to the tangent of the main channel of the throat 102, and the setting of the upper curvature being greater than the lower curvature makes it more difficult for particles such as sand ice to enter the sweepback angle sensitive channel 104, and effectively reduces the vortex intensity of the upper concave surface 105a, and improves the particle pop-out efficiency.

[0045] Preferably, in the embodiment, the horizontal angles of the large-diameter end and the small-diameter end of the upper concave surface 105a are 9° and 19° respectively, and the horizontal angles of the large-diameter end and the small-diameter end of the lower concave surface 105b are 26° and 34° respectively. The included angle between the inlet bevel 102a of the throat 102 and the horizontal incoming flow is 28.7°. Figure 4 As a further scheme of the embodiment, referring to

The arrangement of the suction holes 103 reduces the boundary layer effect of the airflow, weakens the vortex intensity in the separate bend and the sweepback angle sensitive channel 104, makes the airflow in the flow channel more smooth, reduces the formation of vortex flow in the lower concave surface 105b, and enhances the total temperature recovery coefficient. Referring to Figure 3 A circular exhaust passage 102b communicating with the plurality of suction holes 103 is formed through the head shell 1 at the inlet of the separate bend. The circular exhaust passage 102b facilitates the collection and discharge of air in the plurality of suction holes 103, provides the flow permeability of the suction holes 103, and makes the suction holes 103 better reduce the boundary layer effect of the airflow.

[0051] S2, determining the evaluation indexes F1, F2 and F3 of the objective function.

[0052]

[0053] wherein ΔT is the difference between the total temperature in the swept sensitive channel 104 and the theoretical total temperature, r is the total temperature recovery coefficient, C is the ratio of the water content entering the swept sensitive channel 104 to the water content of the circular inlet, A represents the area of the swept sensitive channel 104, unit m 2 ;T i represents the temperature of the grid point of the swept sensitive channel 104, unit K; T represents the average temperature of the swept sensitive channel 104 area, T s represents the static temperature input by the boundary condition, T m represents the theoretical total temperature; m out represents the mass of liquid water entering the swept sensitive channel 104, m in represents the mass of liquid water entering the flow channel from the circular inlet.

[0057] When the three evaluation indicators F1, F2, and F3 meet the conditions at the same time, it means that the total temperature probe is in the most ideal measurement state. F1 = 0 means that there is no loss in total temperature, and the measured temperature is the total temperature. Since this is impossible to achieve from an engineering perspective alone, the measured value and the theoretical value are close to 0. F2 is the total temperature recovery coefficient, that is, F2 should ideally reach above 0.9999. Different Mach numbers and angles of attack will affect F2. F3 = 0 means that ideally, ice crystals and water droplets will not enter the swept angle sensitive channel 104, that is, the swept angle sensitive channel 104 will not freeze, and the total temperature measurement accuracy will not be affected by particulate matter. The specific differences between F1, F2, F3 and the target values ​​can be adjusted according to actual conditions.

[0058] In this embodiment, the Mach number is 0.5 and the sea level is used as the boundary conditions, and the optimization target independent variable x1 = 266.8 mm 2 , x2=0.58,x3=22.9mm 2 , x4 = 85°, x5 is the tangent transition between the upper concave surface 105a and the throat 102, with horizontal angles of 9°:19°, and the horizontal angles of the lower concave surface 105b are 26°:34°. F1 = ΔT = 0.26K, F2 = r = 0.9993, and F3 = C = 0.05%.

Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
