Description

Technical Field

[0001] The present invention relates to the technical field of flight simulators, and more specifically, to an air-conditioning and smoke supply system for an aircraft simulator. Background Art

[0002] As a highly simulated training device, a flight simulator can provide pilots with a near-real flight experience and help them conduct various flight operation trainings in a safe environment. As an important part of the flight simulator, the air-conditioning system undertakes multiple important functions such as delivering fresh air into the cabin, maintaining the specified temperature and humidity in the cabin, creating a good working environment for pilots, and preventing the windshield from fogging up and affecting training. In addition, the air-conditioning system also needs to deliver cooling air to the on-board electrical equipment to provide overheat protection and ensure its normal operation.

[0003] With the progress of technology, the air-conditioning system of simulators is developing towards the direction of intelligence, achieving more efficient and precise temperature and humidity control through an intelligent control system, improving the energy efficiency ratio of the air-conditioning system, and reducing energy consumption. At the same time, integrating the air-conditioning system with the simulator system to achieve a more compact and efficient overall design is also an important direction for future development.

[0004] In the prior art, the air-conditioning system of aircraft simulators still has the following deficiencies:

[0005] In terms of structural principles, the cold air delivery pipes of some air-conditioning systems are not protected, which easily generates condensate, causing the pipe materials to rust and corrode, shortening the service life, and may damage the structural parts or components near the pipes, posing a safety hazard;

[0006] In terms of functional principles, some simulator air-conditioning systems differ greatly from real aircraft, mainly reflected in aspects such as ventilation port design, temperature and humidity adjustment, equipment heat dissipation, and smoke simulation. For example, the air-conditioning systems of some simulators only have a few self-made ventilation ports in the cabin, unable to fully simulate the actual air-conditioning air outlets in the real aircraft cockpit, making it difficult to adjust the temperature and humidity in the cabin according to the preferences of the cabin personnel, greatly reducing the realism and comfort of the simulator. In addition, the heat dissipation functions of various instruments, equipment, and projectors in the cockpit are relatively simple, and even some equipment has no heat dissipation function, which is prone to overheating after long-term operation, affecting its normal operation and lifespan, and thus affecting the effect and safety of simulation training. Moreover, some simulators also have problems such as no or simple setting of the in-cabin smoke simulation / mixing smoke function and the in-cabin smoke extraction and exhaust function, restricting the performance of the simulator in simulating the real flight environment and having a negative impact on the simulation training effect. Finally, the heat dissipation function of the electrical control box is designed too complicated in some simulators, increasing the maintenance difficulty and cost, and may affect the overall performance and stability of the simulator.

[0007] The limitations of the prior art and the urgency of the actual needs indicate that there is an urgent need for a more perfect air-conditioning and smoke supply system for aircraft simulators. Summary of the Invention

[0149] Among them, the top panel vent 1112 of the driver's seat in the cockpit and the top panel vent 1113 of the co-pilot's seat in the cockpit are mainly used to directly deliver the fresh air processed by the air-conditioning system into the cockpit, provide a comfortable air environment for the cockpit, ensure that the temperature, humidity, etc. of the air meet the requirements, so as to guarantee the comfort and safety of the driver.

[0150] The first adjustable air-conditioning vent 1114 and the second adjustable air-conditioning vent 1115 are mainly used to adjust the air flow rate and direction entering the cockpit.

[0158] Specifically, all the air-conditioning vents in the cockpit have the air supply function, which is exactly the same as the real aircraft air-conditioning air supply vents. All air-conditioning pipes are equipped with independent air valves on the distribution box for adjustment or switching, and the air volume can be adjusted according to actual needs to achieve the purpose of energy conservation. In addition, all important electrical components and instruments are equipped with heat dissipation function pipes. There are air supply vents on both the front and back of the mounting backplane of the components in the electrical control box, and an independent real-time detection wind speed transmitter is equipped to ensure the temperature balance and stability of the electrical control cabinet and guarantee the normal operation of the electrical components and instruments.

[0159] In one embodiment, the air-conditioning smoke mixing box is provided with a third air volume valve port, and the third air volume valve port is connected to a smoke outlet of the smoke generator. A check valve is provided at the third air volume valve port to prevent smoke from flowing back.

[0160] In this embodiment, the third air volume valve port corresponds to the first smoke inlet 264 (not shown) of the air-conditioning smoke mixing box 26, which is connected to a smoke outlet of the smoke generator 210 (not shown) through the first smoke pipe 724 for simulating smoke at the air-conditioning outlet.

[0161] After completing the zoning design of the air-conditioning system, the composition and functions of the smoke system will be mainly described next. The smoke system simulates the smoke phenomenon caused by abnormal or short-circuit of electronic equipment to provide a realistic emergency training environment for pilots.

[0162] The connection methods and application scenarios of the smoke generator, PA smoke pipes and related components will be elaborated in detail below.

[0163] In one embodiment, the smoke system may include a smoke generator (including smoke control), PA smoke pipes and related fasteners.

[0164] The smoke system includes a smoke generator and a smoke pipe. The smoke generator is provided with more than one smoke outlet, and the smoke outlets are respectively connected to the air-conditioning smoke mixing box assembly and the area of the front instrument panel of the cockpit through the smoke pipe, mainly for simulating smoke in various electronic devices in the cockpit and at the air-conditioning ventilation outlets of the cockpit. Its function is to simulate the smoke phenomenon caused by the abnormality or short circuit of electronic devices.

[0165] Figure 9 Disclosed is a schematic structural diagram of an air-conditioning - smoke system according to an embodiment of the present invention. In combination with Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 as shown, the smoke generator is arranged near the simulator, and is provided with 2-way PA smoke pipes, which are respectively connected to the air-conditioning smoke mixing box assembly and the designated area of the front instrument panel 111 of the cockpit through fasteners. The flow rate and velocity are controllable, and are used for simulating smoke from equipment failures in the cockpit and at the air-conditioning air outlets.

[0166] In this embodiment, a check valve is provided at the smoke inlet of the air-conditioning smoke mixing box to prevent smoke loss due to backflow, and an independent smoke pipe is provided on the cockpit instrument panel for simulating smoke from instrument failures. The smoke exhaust system adopts a double-fan, double-filter, double-inlet-and-outlet form, and the filter can be replaced or disassembled and cleaned, which improves the smoke exhaust efficiency and environmental cleanliness, and is convenient for maintenance at the same time.

[0169] The smoke exhaust system includes a first smoke exhaust system and a second smoke exhaust system. The smoke is filtered and exhausted through a duct fan, which can quickly empty the simulated smoke in the cockpit and the rear cabin, making the air environment in the cabin clean. When the task of smoke simulation is over, the environment around the driver will immediately return to its original state, improving the training efficiency.

[0170] The simulated smoke carried out by the smoke exhaust system at relevant positions in the cockpit is filtered and exhausted through a series of components such as the filter box, duct fan, duct and diffuser of this smoke exhaust system assembly, and the simulated smoke in the cabin is cleaned and then discharged into the atmosphere.

[0171] Figure 10 Disclosed is a schematic structural diagram of a smoke exhaust system according to an embodiment of the present invention, as Figure 10As shown in the figure, the smoke exhaust system is arranged on the on-board chassis structural member 126 at the left / right bottom of the rear cabin and is fixedly connected by relevant screws (the screws are not shown).

[0172] The smoke exhaust air inlet 911 is located at the left / right rear side position of the inner cabin 1001 of the rear cabin, and the smoke exhaust air outlet is located on the chassis inspection door. Install the first filter box bracket 913 and the second filter box bracket 916 at the corresponding positions of the on-board chassis mechanism member 126 in sequence through corresponding internal hexagonal screws (not shown), and then install the filter box 94 onto the first filter box bracket 913 and the second filter box bracket 916 through M10 hex nuts 914 and M10 screws 915. Secondly, install the fan bracket 912 onto the duct fan 97 through the corresponding internal hexagonal screws (not shown) in sequence, and then bond the third reducer 96 and the fourth reducer 98 to the corresponding positions of the duct fan 97 through adhesives respectively. Then install the duct fan 97 together with the installed components as a whole onto the corresponding position of the on-board chassis structural member 126 through the corresponding internal hexagonal screws (not shown). Finally, connect the installed parts in series with the first aluminum foil exhaust duct 93 and the second aluminum foil exhaust duct 910 in sequence, and bundle and fasten them respectively with the eighteenth hose clamp 92, the nineteenth hose clamp 95, and the twentieth hose clamp 99 to form the smoke exhaust air outlet 91, thus completing the series connection and installation positioning of the smoke exhaust system components.

[0173] Specifically, two sets of smoke exhaust systems are symmetrically arranged in the inner cabin of the rear cabin, both of which can exhaust and extract smoke, making the smoke exhaust speed faster and the efficiency higher.

[0174] An air-conditioning smoke supply system for an aircraft simulator provided by the present invention significantly improves the flexibility of pipe laying and the convenience of maintenance, while reducing costs through an aluminum air-conditioning distribution box and a smoke mixing box structure, in cooperation with a standard PE fresh air hose and connectors, and by taking heat preservation measures; the air-conditioning air supply channels in the cockpit and the rear cabin are designed to be the same as those of the real aircraft, equipped with independent air speed transmitters, greatly meeting the authenticity and comfort of the training of cabin personnel; the setting of the independent air valve can adjust the air volume according to requirements to achieve energy saving; the heat dissipation pipe design of important electrical components and instruments ensures the stability and safety of equipment operation; the setting of the check valve effectively prevents the loss of smoke backflow; the unique U-shaped cooling pipe for the front instrument panel and the top equipment cooling pipe structure in the cockpit achieve efficient heat dissipation of multiple devices; the design of the smoke exhaust system with double fans, double filters, and double inlets and outlets makes the smoke exhaust in the cabin faster, the environment cleaner, and the filters can be replaced or cleaned, making maintenance more convenient.
