Description

Technical Field

[0001] The present invention relates to, but is not limited to, the technical field of civil aircraft safety experiments, and in particular to a variable configuration experimental platform for civil aircraft emergency evacuation simulation tests. Background Art

[0002] In survivable civil aviation accidents, efficient emergency evacuation is a crucial step in protecting occupants in emergencies. Civil aircraft emergency evacuation refers to the process by which passengers and crew members, following prescribed procedures, quickly evacuate to a safe location outside the cabin after an aircraft has made an emergency landing and come to a complete stop. It is characterized by a short duration, a high concentration of personnel, a complex environment, and numerous influencing factors. Statistics from aviation accidents resulting in casualties over the last decade of the 20th century revealed that nearly 94.5% of the crew members who died after the accident died from inhalation of hazardous smoke or severe burns due to a delay in evacuating. Safely and quickly evacuating personnel after an aircraft accident can reduce casualties and increase survival rates. Therefore, emergency evacuation has become a key focus of civil aircraft safety research and airworthiness certification. Research on emergency evacuation in survivable civil aircraft accidents is of great significance and safety value.

[0003] Currently, the same set of civil aircraft emergency evacuation training or experimental facilities can only simulate one configuration of civil aircraft cabin layout. Summary of the Invention

[0037] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any manner.

[0038] As explained in the above background technology, currently the same set of civil aircraft emergency evacuation training or experimental facilities can only simulate one configuration of civil aircraft cabin layout, resulting in poor versatility of the emergency evacuation training or experimental facilities.

[0039] For example, airlines build cabin simulation facilities for specific aircraft models, typically used for crew and flight attendant training. Another example is the simulated cabin (section) test platforms built by civil aircraft design and research departments to address cabin layout design issues during the development of specific civil aircraft models. These are often used to research and verify the rationality of cabin layout designs. However, these facilities are unable to simulate the cabin layouts of both wide-body and narrow-body aircraft, meaning they lack versatility.

[0040] In order to solve the above problems, an embodiment of the present invention provides a variable configuration experimental platform for civil aircraft emergency evacuation simulation tests. The variable configuration experimental platform can be applied to the design, verification and optimization of civil aircraft cabin layout.

[0041] The present invention provides the following specific embodiments that can be combined with each other. The same or similar concepts or processes may not be described in detail in some embodiments.

[0042] Figure 1 This is a schematic diagram of the overall structure of a variable configuration experimental platform for civil aircraft emergency evacuation simulation tests provided by an embodiment of the present invention. Figure 2 for Figure 1 The illustrated embodiment provides a schematic diagram of the layout of the simulated cabin section in a variable configuration experimental platform for civil aircraft emergency evacuation simulation tests. Figure 1 and Figure 2As shown, the variable configuration experimental platform for civil aircraft emergency evacuation simulation test provided by the embodiment of the present invention mainly includes the following components: a simulated cabin section 1, a support platform 2, an escape slide 3, an anti-fall pad 4, a protective net 5, and a movable staircase 6.

[0043] like Figure 1 and Figure 2 In the structure of the variable configuration test platform shown, the support platform 2 includes multiple servo electric cylinders, a bottom mounting frame connected to the bottom end of each servo electric cylinder and placed on the ground, and a top mounting frame connected to the top end of each servo electric cylinder. The simulated cabin segment 1 is fixedly mounted on the top mounting frame, and is used to simulate the pitch and roll attitudes of the simulated cabin segment 1 through the coordinated adjustment of the multiple servo electric cylinders in the support platform 2.

[0044] In the simulated cabin section 1 of the embodiment of the present invention, doors are respectively provided on the left and right sides of the cabin section, one of which simulates the cabin door of a wide-body aircraft, and the other simulates the cabin door of a narrow-body aircraft; boarding doors are respectively provided on the front and rear sides of the simulated cabin section 1, and movable stairs 6 are provided between the boarding doors and the ground for use by participants in the evacuation test to board the aircraft.

[0045] The simulated cabin section 1 of the embodiment of the present invention is provided with an escape slide 3 outside each available door in the current evacuation test. A fall prevention pad 4 is placed at the bottom of each escape slide 3 to cover the lower part of each escape slide 3 and the ground on both sides. In addition, a protective net 5 is installed between each available door and the ground. The protective net 5 is arranged obliquely from the lower part of the door to the ground to cover the lower part and both sides of each available door and the corresponding escape slide 3.

[0046] In one implementation of the embodiment of the present invention, Figure 1 As shown, the doors provided on both sides of the cabin body in the simulated cabin section 1 specifically include:

[0047] A type door is set at the front cabin position on one side, and a type I door is set at the rear cabin position on the same side, which are used to simulate the cabin door in the cabin section of a wide-body passenger aircraft. Type C doors are set at the front cabin position and the rear cabin position on the other side respectively, and a type III door is set at the middle cabin position, which are used to simulate the cabin door in the cabin section of a narrow-body passenger aircraft.

[0048] In one implementation of the embodiment of the present invention, Figure 1 As shown, three seating areas are provided in the middle of the cabin of the simulated cabin section 1, namely: a central seating area and single-sided seating areas on both sides, which are used to simulate the seat distribution in the cabin of a wide-body or narrow-body aircraft; in addition, multiple compartments are arranged on the front and rear sides of the three seating areas, which are used to simulate the power distribution room, control command room and storage room in the cabin.

[0049] Based on the layout of three seating areas, in this implementation, two sets of parallel seat mounting rails are arranged along the span direction on the bottom plate of the middle seating area of ​​the simulated cabin section 1, wherein the first set of rails runs through the entire floor of the simulated cabin section 1 along the span direction, and the second set of rails is arranged on the bottom plate under each row of seats in the central seating area.

[0050] The seat layout in the cabin of a wide-body aircraft is simulated through the A-type door and the I-type door, as well as three seat areas. The seat layout in the cabin of a narrow-body aircraft is simulated through the central seat area, the C-type door, the III-type door, and the single-side seat area on one side of the C-type door and the III-type door. Figure 3 As shown, Figure 2 The illustrated embodiment provides a schematic diagram of the layout of the wide-body and narrow-body cabins in the simulated cabin section of the variable configuration test platform. Figure 3 The three seating areas and two sets of seat mounting rails simulate the seat layout in a wide-body cabin. Figure 3 The central seat area and the single-side seats close to the Type III door simulate the seat layout of a narrow-body aircraft cabin.

[0051] In a specific implementation, the second set of guide rails is installed in a staggered position relative to the rear of the first set of guide rails, and the width of the second set of guide rails is half the width of the cabin plane, which is used to simulate the staggered seat arrangement in the cabin of a wide-body aircraft. In addition, the aisle width is adjusted by changing the installation position of the seats on the two sets of guide rails, thereby implementing the switching of the cabin seat layout between wide-body and narrow-body aircraft.

[0052] In one implementation of the embodiment of the present invention, the simulated cabin section 1 is further provided with a cabin personnel positioning measurement system, such as Figure 4 As shown, Figure 2 The illustrated embodiment provides a schematic diagram of a cabin personnel positioning and measurement system within the simulated cabin section of a variable-configuration test platform. This system can include positioning base stations, positioning tags, and a data processing and storage computer. Multiple positioning base stations are arrayed on the ceiling of the simulated cabin section 1. Each participant in the evacuation test carries a positioning tag, which provides real-time positioning and full-process recording of the participant's evacuation trajectory within the cabin section.

[0053] In one implementation of the embodiment of the present invention, Figure 1 As shown, the multiple servo electric cylinders supporting the platform 2 are configured as a six-degree-of-freedom actuating mechanism, including: 6 attitude control electric cylinders and 4 attitude holding electric cylinders. The attitude of the cabin section 1 is simulated by telescopic adjustment of the 6 attitude control electric cylinders, and the current attitude is maintained by telescopic control of the 4 attitude holding electric cylinders.

[0054] In this implementation, the support platform 2 also includes: a coordinated loading control system for controlling the telescopic adjustment of each servo electric cylinder to achieve attitude adjustment and maintenance of the simulated cabin section 1 within the pitch angle range of -10° to 10° and the roll angle range of -15° to 15°.

[0055] An embodiment of the present invention provides a variable configuration experimental platform for civil aircraft emergency evacuation simulation tests. A simulated cabin section 1 is mounted on a support platform 2, and the pitch and roll attitudes of the simulated cabin section 1 are simulated by adjusting the coordination of multiple servo electric cylinders in the support platform 2. Doors are provided on the left and right sides of the simulated cabin section 1, with one door simulating a wide-body aircraft door and the other door simulating a narrow-body aircraft door. Furthermore, the seats are arranged in partitions within the interior of the simulated cabin section 1 to enable switching between wide-body and narrow-body aircraft cabin components. In this embodiment of the present invention, based on the characteristic of "single-sided evacuation" in actual civil aircraft emergency evacuations, a variable configuration experimental platform for emergency evacuation simulation tests compatible with typical wide-body and narrow-body civil aircraft cabin configurations is provided.

[0056] The variable configuration test platform provided by the embodiments of this invention can be used to study the impact of various cabin layout parameters on the emergency evacuation of civil aircraft crew members, providing technical support for cabin layout design and optimization during the civil aircraft development process. Furthermore, this variable configuration test platform offers advantages such as high operability and efficient cabin configuration switching, significantly reducing the cost and time required for repeated emergency evacuation testing in multiple configurations. It has broad application prospects in the field of civil aircraft safety.

[0057] The following is a schematic illustration of the implementation of the variable configuration experimental platform for civil aircraft emergency evacuation simulation test provided by the embodiment of the present invention through a specific embodiment.

[0058] like Figures 1 to 4 As shown, the configurable test platform for civil aircraft emergency evacuation simulation tests provided in this embodiment includes: a simulated passenger cabin section 1, a support platform 2, an escape slide 3, a fall protection mat 4, a protective net 5, and a movable staircase 6. The components of this configurable test platform and their structural relationships have been specifically described in the above embodiment and will not be repeated here.

[0059] In order to achieve compatible wide-body and narrow-body cabin layout simulation functions on the same experimental platform, the cabin width of the simulated cabin section 1 of the experimental platform is limited to 6m or above with reference to the cabin width of a typical wide-body aircraft; in addition, in order to make the experimental platform represent the typical cabin structure, the total length of the simulated cabin section 1 is limited to 12m or above to cover the cabin area including the front and rear exits.

[0060] Based on the "single-sided evacuation" principle used in actual civil aircraft emergency evacuations, the doors on both sides of the simulated cabin section 1 were designed to match the specifications of wide-body and narrow-body aircraft doors, respectively. Two sets of seat mounting rails were also arranged on the cabin floor to achieve compatibility and conversion between wide-body and narrow-body configurations. The following describes the implementation of each component of the variable configuration experimental platform provided in this embodiment:

[0061] (1) Simulated cabin section 1:

[0062] 1.1, such as Figure 2 As shown, with the front and rear directions indicated by the arrows as reference, the left side of the simulated cabin section 1 is arranged with front and rear doors, of which the left front door is an A-type door and the left rear door is an I-type door, to simulate the doors in a typical wide-body aircraft cabin section; the right side is arranged with front, middle and rear doors, of which the right front door and the right rear door are C-type doors and the right middle door is a III-type door, to simulate the doors in a typical narrow-body aircraft cabin section.

[0063] 1.2, such as Figure 2 As shown, two sets of parallel seat mounting rails are arranged along the span of the central seating area of ​​simulated cabin section 1. The first set of rails runs from the left end of the floor to the right end, spanning the entire floor of simulated cabin section 1. The second set of rails is located only in the central seating area of ​​the seating area, offset rearward relative to the first set (for example, with a controlled offset distance of 0.15-0.2m). The width of the second set of rails is half the cabin plane width, simulating the staggered seat arrangement in a wide-body aircraft cabin. Based on the arrangement of the two sets of seat mounting rails, the aisle width can be adjusted by changing the seat installation position on the mounting rails, and the cabin seating layout can be switched between wide-body and narrow-body aircraft.

[0064] For example, if Figure 3 As shown in the figure, when all the cabin areas in the simulated cabin section 1 are used, the cabin configuration of a wide-body twin-aisle civil aircraft can be simulated, and the available evacuation exits are the A-type door and I-type door on the left; when only Figure 3 In the area within the middle dotted line, the cabin configuration of a narrow-body single-aisle civil aircraft can be simulated, and the available evacuation exits are the front and rear C-type doors on the right side and the middle Type III door.

[0065] In addition, in the simulated cabin section 1, compartment 1 is, for example, a power distribution room, compartment 2 is, for example, a control room, and compartments 3 to 6 are, for example, storage rooms.

[0066] 1.3, such as Figure 4 As shown, the simulated cabin section 1 also includes: a cabin personnel positioning measurement system, which can perform real-time positioning and full-process recording of the evacuation movement trajectory of the test personnel in the cabin section.

[0067] The cabin personnel positioning measurement system is implemented as follows: the cabin personnel positioning measurement adopts "Bluetooth AoA arrival angle positioning technology" and uses the 2.4GHz frequency band to perform wireless positioning and motion trajectory measurement of test personnel. The positioning measurement error range is 0.3m. The cabin personnel positioning measurement system consists of "positioning base station + positioning tag + data processing and storage computer". The positioning base station array is distributed inside the cabin ceiling, with a total of 34 base stations, such as Figure 4 shown.

[0068] (2) Support platform 2:

[0069] like Figure 5 The figure shows a schematic diagram of the structure of the support platform in the variable configuration experimental platform provided by an embodiment of the present invention. The support platform 2 in this embodiment is composed of 10 servo electric cylinders, for example, including: 6 attitude control electric cylinders and 4 attitude maintenance electric cylinders, that is, a six-degree-of-freedom actuating mechanism; through the telescopic adjustment of the 6 attitude control electric cylinders, the attitude adjustment and maintenance of the simulated cabin section 1 within the pitch angle range of -10° to 10° and the roll angle range of -15° to 15° can be achieved, which can cover the pitch and roll parking attitude range that may be caused by partial landing gear failure of today's mainstream narrow-body and wide-body civil aircraft, such as Figures 6 to 8 shown.

[0070] like Figure 6 As shown, Figure 5 A schematic diagram of the support platform of the variable configuration experimental platform provided by the illustrated embodiment in a 10° pitch posture;

[0071] like Figure 7 As shown, Figure 5 A schematic diagram of the support platform in the variable configuration experimental platform provided by the illustrated embodiment in a 15° roll posture;

[0072] like Figure 8 As shown, Figure 5 The embodiment shown is a schematic diagram of a support platform in a variable configuration experimental platform in a composite posture of 10° pitch and 15° roll.

[0073] (3) Escape Slide 3:

[0074] The escape slide 3 is fixed to the outside of the available cabin door of the current evacuation test. For example, if the current evacuation test is a cabin evacuation test of a wide-body passenger aircraft, the escape slide 3 is arranged outside the type A cabin door and the type I cabin door, and a total of two escape slides 3 are arranged; for another example, if the current evacuation test is a cabin evacuation test of a narrow-body passenger aircraft, the escape slide 3 is arranged outside the type C cabin door and the type III cabin door, and a total of three escape slides 3 are arranged; and the escape slide 3 is formed by inflation before use and folded and stored by deflation after use.

[0075] (4) Anti-fall pad 4:

[0076] Based on the arrangement of available doors and escape slides 3 in the current evacuation test, an anti-fall pad 4 is placed at the bottom of each escape slide 3 so that the anti-fall pad 4 covers each available exit and the bottom and both sides of the escape slide 3.

[0077] (5) Protective net 5:

[0078] Based on the available doors in the current evacuation test, and the arrangement of the escape slide (3) and the anti-fall pad (4), the protective net 5 is installed from each available door to the lower part and both sides of the escape slide 3, and is obliquely pulled from the lower part of the available door to the ground.

[0079] (6) Movable staircase 6:

[0080] There are boarding doors on the front and rear sides of the simulated cabin section 1, and a movable staircase 6 is provided between the boarding doors and the ground. The movable staircase 6 is a boarding ladder for the test participants and can be moved and fixed by four liftable pulleys installed at the bottom.

[0081] Although the embodiments disclosed herein are as described above, the contents are merely provided to facilitate understanding of the present invention and are not intended to limit the present invention. Any person skilled in the art may make any modifications and variations in the form and details of the embodiments without departing from the spirit and scope of the present invention.
