Description

Technical Field

[0001] The present invention belongs to the technical field of transportation vehicles, and in particular relates to a modular electric vertical take-off and landing aircraft and a cabin interior. Background Art

[0002] eVTOL is the abbreviation of Electric Vertical Takeoff and Landing, which is translated into Chinese as electric vertical take-off and landing aircraft. The potential applications of eVTOL in the future include urban passenger transport (UAM), regional passenger transport (RAM), cargo, personal aircraft, emergency medical services and other popular scenarios. The target application scenarios set at the beginning of the design of the electric vertical take-off and landing aircraft eVTOL currently developed by COMAC are mainly urban passenger transport (UAM) and regional passenger transport (RAM).

[0003] In response to the passenger transport needs of electric vertical take-off and landing aircraft eVTOL, the cabin design of electric vertical take-off and landing aircraft eVTOL was carried out in the early demonstration stage. Compared with traditional large passenger aircraft, electric vertical take-off and landing aircraft eVTOL are smaller in size and have a smaller and irregular cabin space. The cabin equipment and systems currently used in large passenger aircraft are difficult to be directly applied in the cabin of eVTOL. Compared with traditional helicopters, the current carrying capacity of eVTOL aircraft limits the weight of cabin equipment and systems. Most cabin equipment and systems in the cabin of eVTOL need to be optimized for weight reduction.

[0004] During the eVTOL cockpit design stage, in view of the manned goal of the electric vertical take-off and landing aircraft eVTOL, the different components in the cockpit are designed as replaceable modular products. This allows a cabin space that can meet the travel needs of different groups of people to be combined within the narrow cabin space, and the modular components can be optimized for weight reduction.

[0005] Among the currently available patents, US2022 / 0001990A1 adopts a multi-door design and offset cockpit seats with a certain deflection angle. Due to the different door designs of the cabins, the cabin design of Safran Cabin is based on the door position, and the seats are deflected toward the door opening position, but the offset cockpit seats will occupy a larger space in the cabin space along the span direction of the wing, which does not conform to the more compact design size of the current COMAC eVTOL cabin space. Summary of the invention

[0046] Specifically, the cockpit layout design provided by the present invention is designed in the form of 1+2+2 according to the shape and size of the interior envelope surface. The first row is designed as a driver's seat, and the second and third rows are designed as four passenger seats. The two passengers in the second row are symmetrically distributed on both sides of the symmetry plane of the cockpit. The one passenger in the third row is arranged on one side of the symmetry plane of the cockpit, and the other side is flexibly arranged with another passenger or a modular luggage cabinet and fire extinguisher according to the needs. A modular cockpit layout is designed to meet the needs of 4 and 5 people. Figure 1a and Figure 1b The 3-row seat layout in the cockpit is shown in the figure. The first row has a driver seat No. 15, the second row has two passenger seats No. 11 and No. 12, and the third row can hold two passenger seats. Figure 1a On the other hand, in a 4-person cabin layout, the No. 14 passenger seat can be replaced with the No. 21 modular luggage locker, providing more possibilities for the cockpit layout of the electric vertical take-off and landing aircraft eVTOL.

[0047] Preferably, the symmetrical doors on both sides of the cabin, such as Figure 1a and Figure 1b as well as Figure 2 As shown in No. 1 and No. 2 in the figure, the cabin doors are opened and closed by sliding, which is convenient for all passengers to close the cabin doors by themselves after boarding. Both No. 1 and No. 2 cabin doors are sliding doors. Figure 2 The dotted area shown in Figure 1 shows the detailed design of the exterior of hatch door No. 1, including the entire hatch door, two side windows on the hatch door, and the exterior handle of the hatch door. Figure 2 The gray area in 1a indicates the installation area of ​​the handle on the outside of the hatch, which can be used to fix the hatch handle. The gray area shown in 1b is the sliding track of the hatch, which can be used to fix the hatch and guide the hatch to slide sideways during the opening process. The gray areas shown in 3e and 3f indicate the installation area of ​​the side window on the hatch, which can be used to paste and install the porthole glass.

[0048] Preferably, the symmetrical double doors on both sides of the cabin are used to meet the needs of safe escape when passengers board and leave the aircraft and in emergency situations. The cabin seats near the cabin doors and the driver's seat are fixed to the tracks on the cabin floor through seat slides, which facilitates the flexible adjustment of cabin seats in some key positions. In order to meet the installation requirements of different functional equipment in electric vertical take-off and landing aircraft, most of the modular components in the cabin interior are fixed to different positions in the cabin by the cabin floor tracks. A total of six cabin floor tracks are arranged in the cabin, including Figure 3 41a and 41b are short rails on the cabin floor for fixing the driver's seat, while 42a, 42b, 42c and 42d are long rails on the cabin floor for fixing the second and third row seats and luggage cabinets. In addition, 43a, 43b, 43c and 43d are seat slides that can be fixed on the seat floor rails, which can facilitate passengers to flexibly adjust the front and rear distance of the seats and facilitate the occupants of the driver's seat to enter their own seating area. The cabin seats are fixedly installed on the cabin floor rails, such as Figure 4b As shown in FIG. 1 , the seat Y-shaped support arm 13a-1 is fixed to the cabin floor track 42d by bolts. The Y-shaped support arm can support the main weight of the seat and the passenger, and provide a certain degree of support for the backward impact during the flight. The cabin seat can also be fixed to the cabin floor track by the seat slide rail, as shown in FIG. Figure 4a As shown in the figure, the Y-shaped arm 15a-1 of the seat can be fixed to the slider 43b-1 of the seat slide rail by bolts, and the track 43b-2 of the seat slide rail can also be fixed to the cabin floor track 41b by bolts. The passenger seat and the driver seat use different seat components. Figure 6aThe overall form of the driver's seat is shown in the figure, including double seat armrests 15b-1 and 15b-2. In addition, the seat headrest 15c is designed to be flat, providing a wider field of vision for the driver. The passenger seat is slightly different from the driver's seat. The passenger seat uses a seat headrest with a certain bending angle, which can protect the passenger's privacy on the one hand and facilitate the passenger to enjoy the scenery outside the window on the other hand. Figure 6b As shown in , the passenger seats are symmetrically distributed on both sides of the cabin, and the headrests of the two seats in the same row have a bent design in the adjacent area, which can reduce the visual contact between the passengers on both sides and provide lateral support for the passengers' heads, as shown in 11c and 12c. In addition, the cabin seats on both sides of the cabin are only equipped with inner armrests 11b and 12b, which reduces the occupation of the limited space in the cabin by the outer armrests and prevents the outer armrests from interfering with passengers getting on and off.

[0049] Preferably, a modular luggage locker is designed for the lack of space for luggage in the cabin. The modular luggage locker can be fixed on the cabin floor track by fixing bolts similar to those on the seats, such as Figure 5 As shown, the luggage cabinet bracket 42a can be fixedly connected to the cabin floor track 42a by bolts. In addition to fixing passenger luggage with some metal brackets, the modular luggage cabinet also has a partial fabric enclosure on one side to restrain the luggage to prevent some sharp objects from invading the passenger seating area during vibration. The use of partial fabric material can greatly reduce the overall weight of the modular luggage cabinet. The modular luggage cabinet consists of two different areas. The area used to fix objects such as suitcases is covered with two different soft materials. Figure 7a and Figure 7b 21c-1 and 21c-2 are made of breathable fabric, and 21c-3 is made of soft bandage, which work together to restrain the shaking of suitcases and other items in the luggage cabinet. Another area 21d of the luggage cabinet can be used to fix the fire extinguisher 22. This area is composed of a hard plastic cabinet provided by 21d, and the cabinet is also provided with a bracket for additionally restraining the fire extinguisher 22.
