Description

Technical Field

[0001] This utility model relates to the field of aircraft component technology, and in particular to an environmental control system and a vertical take-off and landing electric aircraft having the same. Background Technology

[0002] With the development of aviation technology, the number of electric vertical takeoff and landing (VTOL) aircraft has grown rapidly, becoming one of the hottest modes of transportation in the future. In manned VTOL electric aircraft, the environmental control system, as a system directly related to passenger comfort, has become a research hotspot for various manufacturers and laboratories. However, in current technology, the environmental control systems of VTOL electric aircraft cannot adapt to the aircraft's changing operating environment, resulting in lower passenger comfort and a poorer experience. Utility Model Content

[0003] This invention provides an environmental control system and a vertical takeoff and landing electric aircraft having the same. The environmental control system can adapt to the changing working environment of the aircraft and improve the comfort and experience of the passengers.

[0004] This utility model provides an environmental control system, including an air conditioning unit, a first air outlet duct, a second air outlet duct, and a return air duct. The first air outlet duct, the second air outlet duct, and the return air duct are all connected to the air conditioning unit. The first air outlet duct and the second air outlet duct are installed on the top of the aircraft fuselage. The air outlet of the first air outlet duct faces the windshield of the aircraft fuselage, and the air outlet of the second air outlet duct faces the passenger compartment of the aircraft fuselage. The air outlets of the first air outlet duct and the second air outlet duct are both installed in the upper part of the passenger compartment, while the return air duct's return air outlet is installed in the lower part of the passenger compartment.

[0005] Furthermore, a second control valve is also provided on the return air duct for adjusting the opening degree of the return air duct.

[0006] Furthermore, the second air outlet is provided with multiple air outlets, some of which are directed toward the front row of the passenger compartment, and some of which are directed toward the rear row of the passenger compartment.

[0007] Furthermore, the environmental control system includes a support frame for fixing to the passenger compartment, and the first air outlet duct and the second air outlet duct are fixed to the support frame.

[0008] Furthermore, there are multiple return air ducts and multiple return air inlets, with the multiple return air inlets located at different positions in the return air ducts and facing different directions.

[0009] Furthermore, the environmental control system includes a fresh air duct, one end of which is connected to the air conditioning unit and the other end is connected to the outside of the aircraft fuselage. A third control valve is provided on the fresh air duct for adjusting the opening degree of the fresh air duct.

[0010] Furthermore, the environmental control system includes a pressure relief valve installed on the fuselage and connected to the inside and outside of the crew compartment. When the pressure difference between the inside and outside of the crew compartment reaches a set pressure difference, the pressure relief valve opens.

[0011] This invention also provides a vertical takeoff and landing electric aircraft, including the aforementioned environmental control system.

[0012] Furthermore, a pressure relief port is provided on the fuselage of the vertical takeoff and landing electric aircraft, and a pressure relief valve is provided in the pressure relief port. When the pressure difference between the inside and outside of the crew cabin reaches a set pressure difference, the pressure relief valve opens.

[0013] Furthermore, an air conditioning equipment compartment is provided on the body of the unit, and a fresh air inlet is provided on the windward side of the air conditioning equipment compartment. The environmental control system includes a fresh air duct, one end of which is connected to the air conditioning unit and the other end is connected to the fresh air inlet.

[0014] In summary, this invention utilizes an air conditioning unit, a first air outlet duct, a second air outlet duct, and a return air duct. When the air conditioning unit starts, it directs temperature-adjusted airflow towards the windshield and passenger compartment to defog the windshield and regulate the passenger compartment environment. Simultaneously with the airflow exiting the first and second air outlet ducts, the airflow re-enters the air conditioning unit through the return air duct's inlet, located at the bottom of the passenger compartment, completing air circulation. Since the outlets of the first and second air outlet ducts are located in the upper part of the passenger compartment, while the return air duct's inlet is located in the lower part, the circulating airflow can pass through the entire passenger compartment, facilitating airflow throughout the cabin and enabling effective regulation of the overall passenger compartment environment. Therefore, this environmental control system can adapt to the changing working environment of an aircraft, improving passenger comfort and experience.

[0026] This invention provides an environmental control system and a vertical takeoff and landing electric aircraft having the same. The environmental control system can adapt to the changing working environment of the aircraft and improve the comfort and experience of the passengers.

[0027] like Figures 1 to 4 As shown, the environmental control system provided in this embodiment of the present invention includes an air conditioning unit 10, a first air outlet duct 21, a second air outlet duct 22, and a return air duct 30. The first air outlet duct 21, the second air outlet duct 22, and the return air duct 30 are all connected to the air conditioning unit 10. The first air outlet duct 21 and the second air outlet duct 22 are installed on the top of the aircraft fuselage. The air outlet of the first air outlet duct 21 faces the windshield of the aircraft fuselage, and the air outlet of the second air outlet duct 22 faces the passenger compartment 80 of the aircraft fuselage. The air outlets of the first air outlet duct 21 and the second air outlet duct 22 are located in the upper part of the passenger compartment 80, and the return air outlet of the return air duct 30 is located in the lower part of the passenger compartment 80.

[0028] In this embodiment, the air conditioning unit 10, the first air outlet duct 21, the second air outlet duct 22, and the return air duct 30 are configured. When the air conditioning unit 10 is started, it blows temperature-adjusted airflow towards the windshield and the passenger cabin 80 to defog the windshield and regulate the environment inside the passenger cabin 80. While air is being discharged from the first air outlet duct 21 and the second air outlet 22, the airflow can re-enter the air conditioning unit 10 through the return air inlet of the return air duct 30, which is located at the lower part of the passenger cabin 80, completing air circulation. Since the air outlets of the first air outlet duct 21 and the second air outlet 22 are located at the upper part of the passenger cabin 80, while the return air inlet of the return air duct 30 is located at the lower part of the passenger cabin 80, the circulating airflow can pass through the entire passenger cabin 80, which is beneficial for air circulation throughout the passenger cabin 80 and facilitates the regulation of the environment inside the passenger cabin 80. Therefore, this environmental control system can adapt to the changing working environment of the aircraft, improving passenger comfort and experience.

[0029] Furthermore, in this embodiment, a first control valve 221 for adjusting the opening of the second air outlet 22 is also provided on the second air outlet 22. When there is a lot of fog on the aircraft windshield, the opening of the second air outlet 22 can be reduced by the first control valve 221, or the second air outlet 22 can be closed directly, so that more airflow is blown onto the windshield through the air outlet on the first air outlet 21, thereby powerfully defogging the windshield.

[0030] Furthermore, a second control valve 31 is also provided on the return air duct 30 for adjusting the opening of the return air duct 30. The return air volume of the environmental control system can be adjusted through the second control valve 31.

[0031] Please continue reading Figure 1 and Figure 4 In this embodiment, the second air outlet 22 may be provided with multiple air outlets, which are directed toward different positions in the passenger compartment 80. For example, some air outlets of the second air outlet 22 may be directed toward the driver in the front row of the passenger compartment 80, while other air outlets of the second air outlet 22 may be directed toward the passengers in the rear row of the passenger compartment 80. The shape of the air outlets on the second air outlet 22 can be set as needed.

[0032] Furthermore, in this embodiment, the environmental control system also includes a support frame 40 for fixing to the top of the passenger compartment 80. The first air outlet 21 and the second air outlet 22 are both fixed on the support frame 40 to facilitate the installation of the first air outlet 21 and the second air outlet 22.

[0033] There can be multiple return air ducts 30, and multiple return air inlets can also be installed on the return air ducts 30. These multiple return air inlets can be located at different positions within the return air ducts 30 and face different directions. For example... Figure 4 As shown, there can be two return air ducts 30. On one return air duct 30, one return air inlet is positioned forward, and the other is positioned downward. On the other return air duct 30, one return air inlet is positioned backward, and the other is positioned downward. It should be noted that, for easier display of the rearward-facing return air inlet, Figure 4 In the middle, part of the sidewall of the return air duct 30 is omitted.

[0034] Furthermore, in this embodiment, the environmental control system also includes a fresh air duct 50, one end of which is connected to the air conditioning unit 10, and the other end is connected to the outside of the aircraft fuselage. That is, the fresh air duct 50 can introduce outside air into the fuselage. When the passenger cabin 80 needs to introduce fresh air, the outside air can enter the air conditioning unit 10 through the fresh air duct 50 and then enter the passenger cabin 80 through the air conditioning unit 10.

[0035] A third control valve 51 is installed on the fresh air duct 50 to adjust the opening degree of the fresh air duct 50.

[0036] Furthermore, the environmental control system also includes a pressure relief valve 60 mounted on the fuselage and connected to the inside and outside of the passenger compartment 80. When the air pressure inside the passenger compartment 80 is reduced to a set pressure difference with the outside air pressure due to certain reasons, such as the introduction of fresh air through the fresh air duct 50, the pressure relief valve 60 can actively open due to the pressure difference, thus relieving pressure in the passenger compartment 80. When the pressure difference between the passenger compartment 80 and the outside air is less than the set value, the pressure relief valve 60 closes, and air circulation only occurs inside the passenger compartment 80.

[0037] In summary, this utility model utilizes the configuration of an air conditioning unit 10, a first air outlet duct 21, a second air outlet duct 22, and a return air duct 30. When the air conditioning unit 10 is started, it directs temperature-adjusted airflow towards the windshield and passenger compartment 80 to defog the windshield and regulate the environment within the passenger compartment 80. Simultaneously with the airflow exiting through the first and second air outlet ducts 21 and 22, the airflow can re-enter the air conditioning unit 10 through the return air inlet of the return air duct 30, located at the lower part of the passenger compartment 80, thus completing air circulation. Since the air outlets of the first and second air outlet ducts 21 and 22 are located at the upper part of the passenger compartment 80, while the return air inlet of the return air duct 30 is located at the lower part of the passenger compartment 80, the circulating airflow can pass through the entire passenger compartment 80, facilitating airflow throughout the passenger compartment 80 and enabling effective regulation of the environment within the passenger compartment 80. Therefore, this environmental control system can adapt to the changing working environment of the aircraft, improving the comfort and experience of the passengers.

[0038] This invention also provides a vertical takeoff and landing electric aircraft, which includes the aforementioned environmental control system.

[0039] Furthermore, a pressure relief vent is also provided on the fuselage of this vertical takeoff and landing electric aircraft, and a pressure relief valve 60 is disposed within the pressure relief vent. In this embodiment, the pressure relief vent is located on the side of the fuselage and below the passenger compartment 80, so as to connect the inside and outside of the fuselage. In other embodiments, it may also be located between the passenger compartment 80 and other compartments of the fuselage, such as the baggage compartment, so that the passenger compartment 80 cannot be directly connected to the outside of the fuselage through the pressure relief valve 60.

[0040] Furthermore, an air conditioning equipment compartment 70 is also provided on the fuselage. The air conditioning equipment compartment 70 is located at the rear of the passenger compartment 80 and above the baggage compartment. The aforementioned air conditioning unit 10 is located inside the air conditioning equipment compartment 70. A fresh air inlet 71 is provided on the windward side of the air conditioning equipment compartment 70. The end of the fresh air duct 50 away from the air conditioning unit 10 is connected to the fresh air inlet 71.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
