Description

Technical Field

[0001] The invention belongs to the technical field of aircraft training, and in particular relates to a training device for aircraft take-off and landing. Background Art

[0002] As aircraft applications become more and more widespread, the take-off and landing locations of aircraft are becoming more and more diverse, and there may be situations where they land on unstable ground. The landing platform may have roll, pitch, and heave movements, which will affect the take-off and landing of the aircraft, and even affect safety and bring danger.

[0003] Therefore, there is a need for a landing platform that can provide operators with different movements (movement modes, movement parameters), similar to the roll, pitch and heave movements of a ship, and has adjustable movement parameters.

[0004] At present, aircraft training generally uses computer simulation, visual and other technologies, which are limited to flight control functions and preset track verification, operation command response testing and other aspects. There are few practical training devices involving aircraft. Practical training devices can adjust motion parameters, shorten training or test cycles, quickly improve operator skills and reduce control loads, thereby improving the positioning accuracy and safety factor of the aircraft when taking off or landing on the landing platform. Summary of the invention

[0005] The present invention provides a training device for aircraft take-off and landing, which belongs to the field of practical training devices for aircraft operators and involves relevant knowledge such as mechanical design, automatic control and civil construction. It is a simulation training device for operators of medium and large aircraft systems that can be used in the field (field) for a long time in subtropical monsoon humid climate areas.

[0006] The present invention provides a training device for aircraft take-off and landing, comprising: an upper platform, N drive cylinders, M auxiliary supports, a base, a wall and a water collection pool;

[0007] The base is set in a deep pit on the ground, the upper surface of the base is lower than the ground, a wall is set on the upper surface of the base, the height of the wall is higher than the ground, a water collection pool is set on the side of the base, and a connecting pipe is set in the base to drain the water on the upper surface of the base to the water collection pool;

[0008] N driving cylinders and M auxiliary supports are arranged in the wall on the upper surface of the base, and the top ends of the N driving cylinders and the M auxiliary supports are connected to an upper platform, which is used for aircraft take-off and landing training. N and M are positive integers greater than 1.

The auxiliary support driven by air pressure can generate a driving force to offset the gravity of the upper platform itself, thereby greatly reducing the load of the drive cylinder and extending the service life. Two different protection strategies are designed to deal with the emergency disposal process after the failure of different numbers of drive cylinders, so as to ensure that the unmanned helicopter is not damaged; when a drive cylinder fails, the upper platform can reach a horizontal state in the shortest time according to the optimal path, that is, the platform is leveled; if multiple drive cylinders fail, the upper platform can brake immediately. A fence is built to enable the whole set of equipment to have the ability to prevent the backflow of accumulated (rain) water, avoid water damage to electrical equipment, and enable the training device to be used for a long time in the field (field) in subtropical monsoon humid climate areas, meeting the application scope and service life of the whole set of equipment. A water collection pool was built, the lower bottom surface of which was lower than the upper surface of the base, so that the accumulated water on the base could automatically flow into the water collection pool, improving the environmental humidity of the internal space of the enclosure and slowing down the corrosion rate of the entire equipment.

[0031] like Figure 1-2 As shown, the present invention provides a training device for aircraft take-off and landing, comprising: an upper platform, N drive cylinders, M auxiliary supports, a base, a wall and a water collection pool;

[0032] The base is set in a deep pit on the ground, the upper surface of the base is lower than the ground, a wall is set on the upper surface of the base, the height of the wall is higher than the ground, a water collection pool is set on the side of the base, and a connecting pipe is set in the base to drain the water on the upper surface of the base to the water collection pool;

[0033] N driving cylinders and M auxiliary supports are arranged in the wall on the upper surface of the base, and the top ends of the N driving cylinders and the M auxiliary supports are connected to an upper platform, which is used for aircraft take-off and landing training. N and M are positive integers greater than 1.

[0034] Optionally, the aircraft take-off and landing training device further includes: an upper platform controller;

[0035] The upper platform controller is connected to the N driving cylinders respectively to obtain the working status of each of the N driving cylinders; the working status includes normal and fault;

[0036] The upper platform controller is used to adjust the telescopic displacement of the remaining driving cylinders according to the telescopic displacement of the faulty driving cylinder to achieve leveling of the upper platform when a faulty driving cylinder is detected among the N driving cylinders.

[0037] Optionally, the upper platform controller is specifically configured to lock all the driving cylinders simultaneously to brake the upper platform when it is detected that at least one driving cylinder among the N driving cylinders is faulty.

[0038] Optionally, the upper platform is rectangular and is provided with a kinematic hinge mounting interface for mounting and connecting N drive cylinders and M auxiliary supports.

[0039] Optionally, the height of the upper platform is higher than the surrounding wall, and the length and width of the upper platform are both larger than the outer dimensions of the surrounding wall.

[0040] Optional, the value of N is 6 and the value of M is 4.

[0041] Optionally, the upper platform controller monitors the operating status parameters of the entire training device in real time, including the extension and retraction amount, extension and retraction speed and other information of the N drive cylinders; the upper platform controller uses the extension and retraction displacement of the N drive cylinders as the instruction value, controls the extension and retraction of the motor and the drive cylinder to achieve the instruction value.

[0042] Under normal conditions, the upper platform controller can detect the status of a single electric cylinder; when a fault occurs, it can determine whether to output command values ​​normally to the drive cylinder or brake.

[0043] Optionally, the upper platform controller is used to achieve a composite superposition of the roll, pitch and heave motions of the upper platform by controlling the coordinated motions of a plurality of drive cylinders.

[0044] Exemplarily, in a specific embodiment, the automation device provided by the present invention can simulate the movement of ships in sea conditions of level 5 and below, and provide the required training equipment and testing environment for aircraft operators.

[0045] The present invention takes into account that aircraft training grounds are generally far away from urban areas, located in remote areas or areas with complex terrain. The training equipment needs to be used and stored in the field environment for a long time. In order to ensure long-term use, it is necessary to focus on the prevention or disposal of abnormal situations such as rainwater, backflow of accumulated water, etc. of the entire set of equipment in complex and severe weather environments.

[0046] The training device for aircraft operators is composed of an upper platform 1-4, a drive cylinder 1-2, an auxiliary support 1-3, a base 1-1 and a water collection tank 1-7;

[0047] The coordinated movement of multiple drive cylinders simulates the movement of the ship (roll, pitch and heave), providing operators with a realistic scenario of the landing and take-off process of an unmanned helicopter;

[0048] The training device for aircraft operators has two different protection strategies. If a single electric cylinder or motor fails, the upper platform will first slow down and stop the current action, and then level it according to the optimal path; if two electric cylinders or motors fail, the electric cylinders will be locked at the same time and the upper platform will brake to ensure that the upper platform will not overturn or other uncontrollable situations occur;

[0049] The auxiliary support is composed of cylinders, gas tanks, valve groups, and pipeline systems. Multiple cylinders are used to balance the weight of the upper platform, and multiple gas tanks are set to ensure that the cylinder pressure fluctuations caused by the change of the upper platform posture can quickly reach a balanced state.

[0050] With the ground as the height reference plane, the training device for aircraft operators needs to build a base below the reference plane, and build a wall 1-5 above the ground on the base, so that the interior of the combination of the base and the wall has the ability to prevent the backflow of accumulated (rain) water.

[0051] The length of the upper platform is greater than the width of the base, and the width of the upper platform is greater than the width of the base. The upper platform is installed at the top of the entire device. In extreme cases of continuous heavy rain or even rainstorms, the upper platform can block (shield) rainwater and prevent it from falling into the combination of the base and the wall.

[0052] The training device for aircraft operators needs to build a water collection pool, the bottom of which should be lower than the bottom surface of the base, and an inclined connecting pipe 1-6 is installed between the base and the water collection pool to ensure that the accumulated water in the base can automatically flow into the pit.
