Tupu software digital twin civil aviation flight networking, building a new smart civil aviation business

foreword

The "14th Five-Year Plan" General Aviation Development Special Plan clarifies that by the end of the "14th Five-Year Plan", strive to achieve 3,500 general aviation aircraft, 500 airports, and no less than 25 provinces to carry out general aviation emergency rescue services. At the same time, my country has built and put into operation the world's leading "Three Air Traffic Control Centers" (Civil Aviation Operation Management Center, Meteorological Center, and Information Management Center), which has significantly improved civil aviation's refined service capabilities.

Through the Tupu software visualization system, the aircraft shape, cabin management, cabin equipment, engine, and cab are digitally twinned in a sci-tech style, and various data are sorted through the Internet, cloud computing, big data analysis, artificial intelligence and other technologies. After integrated analysis and analysis, it is displayed on the hightopo visual large screen, and a scene-based, intelligent and humanized intelligent aircraft comprehensive management and control platform is established to provide managers with diversified, multi-angle and multi-data management and decision-making basis. Through the practice of the Civil Aviation Metaverse, a green, intelligent and safe intelligent civil aviation management system will be built.

model selection

The 3D scene of the Tupu visualization system takes 3 different types of aircraft as examples to display the appearance parameters. Airbus A380 (Airbus A380) is a super-large long-range wide-body airliner with four engines developed and produced by European Airbus. The Boeing 787 was the first ultra-long-range medium-sized passenger aircraft in aviation history. Boeing 727 (Boeing 727) is a short- and medium-range civil aircraft developed and produced by the Boeing Company of the United States.

Using technologies such as virtual simulation and digital twin, combined with Tupu software's self-developed engine HT for Web to render a seamless 2D and 3D flight scene, simulating the aerodynamic layout and wing geometry of Airbus A380, Boeing 787 and Boeing 727 parameters, etc.

After selecting a model, the overall shape of the currently selected model will be displayed in a roaming animation. Clicking the gradient triangle next to different models will pop up an introduction to the current airliner to learn about the airliner's history, engine, engine, etc. The real-time flight data is connected to the large visual screen of Tupu, and the flight management systems of various flying aircraft are seamlessly linked, and the equipment data and passenger status of the aircraft are monitored in real time, so as to realize the real-time sharing of data between the tower and the flying aircraft. Early warning and post-event review can effectively reduce the occurrence of various aviation accidents.

The new generation of IoT communication based on α-link technology relies on the technical advantages of advanced aeronautical radios, improves the transmission efficiency of information and expands the number of connections, and optimizes the limitation that Bluetooth cannot be deployed on a large scale in limited areas. Duplex communication to achieve the goal of interconnection of all things, digital empowerment, and precise monitoring.

Tupu software is based on the 3D engine independently developed by WebGL, which can smoothly display the 3D scene and model of the aircraft in the browser, and can also create complex navigation and data visualization. Access to real-time data such as the aircraft's wingspan, fuel load, and interference resistance to achieve refined flight management. Simulate real-time flight images for an immersive look and feel. Through Tupu software, a one-stop development tool from view component design, icon design, 2D drawing design to 3D scene design, designers and programmers can achieve collaborative development and quickly implement 2D and 3D visualization results of different models.

Passenger aircraft parameters

The monitoring data of the airport is connected to the Tupu visualization system to display the wing, fuselage, tail, landing gear, control system and power unit, interference resistance, full load rate of the cargo compartment, etc. flight management.

interference resistance

In addition to frictional resistance, differential pressure resistance and induced resistance, "interference resistance" is an additional resistance caused by the mutual interference of airflow between various parts of the aircraft wing, fuselage, tail, etc. When designing an aircraft, careful consideration of their relative positions can reduce interference drag. Connect the real-time resistance data to the Hightopo visualization system. When the resistance is too large, a red triangle warning with an exclamation mark will appear. The ground control tower can contact the crew in time to confirm whether the flight is safe. The recording of historical data can also be used for the optimization of subsequent aircraft designs.

oil load

The fuel capacity of an aircraft is divided into three categories: maximum fuel capacity, minimum fuel capacity, and take-off fuel capacity. The maximum fuel capacity is the maximum fuel capacity that the aircraft can carry when the aircraft is in safe flight. The minimum fuel load refers to the amount of fuel that the aircraft can fly over the airport at the waiting airspeed for 30 minutes after arriving at the landing airport. The take-off fuel quantity refers to the total fuel quantity carried by the aircraft when performing the flight mission.

In January 2022, the Civil Aviation Administration of China issued the "14th Five-Year Plan for the Green Development of Civil Aviation", which clearly stated that the goal of achieving carbon peaks, carbon neutrality and "dual carbon" should be the guide to promote the comprehensive green transformation of civil aviation development. Combined with technologies such as sensors and 5G, the fuel load data is connected to the 2D panel of the Tupu visualization system, so as to control the fuel consumption at all times and reduce the fuel consumption ratio. Keeping the actual fuel used as close to the theoretical minimum as possible is the most direct way to reduce carbon emissions from civil aviation.

Cargo Hold Information

Tupu software HT visualization uses rich charts, graphics and design elements to display the data of general cargo, chemicals, overweight items, and fresh items in a more intuitive and understandable form. Connect the real-time data of the cargo hold with the data of the ground passenger and cargo transportation service area to improve the loading and unloading efficiency of the airport.

The loading capacity of the cargo compartment is mainly limited by weight limitation, volume limitation, door size limitation and floor bearing capacity. For example, the maximum cargo capacity of Airbus A380 is 66.4 tons. The loading capacity data of the aircraft type is accessed in the 2D panel visualized by Tupu software HT, the current full load rate of the cargo compartment is displayed in percentage, and the data information is clearly and effectively interpreted and conveyed by graphical means. Through the visualization of Tupu software, unmanned monitoring of the cargo compartment, fire warning, etc. can also be realized.

Cabin management

The "Big Mac" A380 is the most passenger-carrying civil airliner in the world. Many A380s have gyms, bathrooms, restaurants, bars and other entertainment venues to add fun to passengers' flight. The Tupu software visualization system splits and displays the two-story cabin and luggage compartment of the passenger plane, visualizes the structure, layout, facilities and equipment in the cabin, and corresponds to its actual location and number one by one, keeping it consistent with the actual scene.

The cabin is divided into first class, business class and economy class according to the spaciousness and comfort of the seats. Connect the ticketing system with the Tupu software visualization system, and distinguish the optional seats, non-selectable seats, and VIP seats by color, and the remaining seats can be viewed. For flights with long routes between the two places and insufficient passenger supply, the remaining seats can be sold to increase the boarding rate.

Passenger body temperature

At the moment of the epidemic, the results of body temperature detection for epidemic prevention are displayed with a heat map, and the body temperature of passengers with high body temperature is listed separately, and the crew members take targeted measures.

Passenger information

The statistics of membership level, user name, registration number, available mileage and other information can be visualized and displayed through the Tupu software, which enables the flight attendants to adopt more appropriate customer service measures.

flight information

Synchronize the flight route and flight information of the aircraft, such as departure and destination, and transmit the information to passengers and ground towers. Commercial aircraft are required to signal their position at least every 15 minutes.

Cabin Equipment

Click on the cabin equipment to drill down to the details page to view the passenger volume, flight information, flight system, passenger age group and household registration distribution and other related information.

Using the wireframe mode with a sense of technology, the aircraft shell is transparently processed, and the equipment in the cabin is at a glance, which is convenient for operation and maintenance to view the overall layout structure. Connect the equipment data to the Tupu software visualization system, and give early warning in time for failures to ensure the safety of the flight process. After accessing the data of passenger information, you can view the distribution of passenger nationalities from the flashing small spots on the global map, and provide personalized services.

aircraft equipment view

Click on the aircraft equipment view, the transparent mask of the aircraft is automatically removed, and click on the internal equipment to display the equipment name and purpose. Using the HT virtual simulation technology of Tupu software, according to the appearance of the actual aircraft, a 3D visual simulation interactive model of the aircraft is produced. On the premise that it is completely consistent with the actual aircraft, it is committed to displaying a high-precision model, and the flight data is driven by real-time data.

Equipment self-test

Equipment data monitoring is in-process supervision, and equipment self-inspection is an advance reminder. The 2D panel of the Tupu Civil Aviation visualization interface scrolls to display the safety system status at the current time, and the intelligent early warning analysis function is added. Once the system data exceeds the set threshold, the information will be marked in red in the list, and the maintenance personnel need to check the health status of the equipment in time .

Aircraft system display

A flight management system (FMS) automates flight missions. Airborne Health Management System (AHMS) includes aircraft health monitoring, diagnosis, assessment, etc. The Atmospheric Inertial Navigation System (ADIRSP) measures the position, speed, track, wind direction/speed, attitude, etc. of the aircraft. The Information System (IS) provides flight information, maintenance information, cabin information and operational information services. The Integrated Modular Platform (IMA) is based on core computing, RTOS, and onboard networking to support system interconnection and data interworking. The main purpose of the communication system (CNS) is to make the aircraft maintain two-way voice and signal contact with the air traffic control personnel, dispatch, maintenance and other related personnel on the ground during various stages of flight. Display System (CDS) refers to a device that provides pilots with integrated monitoring and cockpit display control systems that optimize situational awareness.

The aircraft system is combined with the smart airport system to perform refined flight management through Tupu visualization.

Relying on accurate spatiotemporal perception and ubiquitous interconnection of all targets in the flight area, Tupu Smart Airport builds a "picture of the situation" to realize the visualization of all elements; through multi-dimensional data aggregation and fusion, reasoning and decision-making knowledge map, the whole process is measurable; through interconnection Interoperability and intelligent collaboration to achieve full scene control; seize the opportunity of digital transformation.

Aviation activities are an integral sector of transportation, and together with rail, road, water and pipeline transportation, make up the country's transportation system. For the green digital transformation of water transportation, Hightopo visualization products can also be used to solve the problems of high energy consumption, high cost and large pollution of traditional terminals and ships.

engine

An aircraft power unit is a device used to generate pull (propeller aircraft) or thrust (jet aircraft) to move the aircraft forward. In modern aircraft, in addition to supersonic aircraft and high subsonic mainline passenger aircraft, propeller aircraft still occupy an important position. Taking the TRENT 900 specification engine as an example, the all-round display of the engine is carried out in four ways: section, airflow, split and reset. The TRENT 900 turbofan engine is a turbofan engine consisting of a compressor, a combustion chamber, a high-pressure turbine (driving the compressor), a low-pressure turbine (driving the fan) and an exhaust system.

The cutaway shows HP turbine blade power, there are 70 HP turbine blades on the Trent 900 engine, each producing nearly 600 kWh. Through the data binding of the 2D panel and the chart of the graph flutter visualization, the pressure and temperature changes are displayed by the line chart.

The airflow page shows the propulsion efficiency of different types of turbojet engines, the inlet airflow value, the aerodynamic load, thermal load, centrifugal load and other indices, with red arrows and green arrows to distinguish the incoming and outgoing airflow.

Hightopo shows the internal structure of the engine in the form of equipment splitting and explosion, showing the names of various parts of the engine, such as hollow structure fan blades, titanium alloy honeycomb core, honeycomb sandwich, superplastic forming wide chord fan, etc. After disassembling the engine, you can view every subtle part one by one. By accessing the IoT data of components, you can view the current status of each component of the equipment, and realize global monitoring and visualization from macro to micro.

The reset state can view thrust, total pressure ratio, inlet mass flow, fan diameter, length, weight, grade fan, 8-stage intermediate pressure compressor (IPC), 6-stage intermediate pressure compressor (HPC), annular combustion chamber, duct ratio data. The bypass ratio is the ratio of the air flow between the outer and inner ducts of the turbofan engine, and the bypass ratio is closely related to the fuel consumption rate.

The Tupu software uses the event mechanism to update the interface locally, avoids the FPS game mode, performs too many meaningless interface refreshes, and avoids problems such as desktop freezes and hot mobile phones.

cockpit

The aircraft control system refers to the entire system from the pilot's control stick (disk) in the cockpit to the control surfaces such as the horizontal tail, aileron, rudder, etc., which is used to transmit the pilot's control instructions and change the flight state. Various flight instruments and aircraft control systems are generally installed in the cockpit of an aircraft.

A Mode Control Panel (MCP) is a device that instructs the autopilot for course, altitude, ascent and descent rates, and speed. The Primary Flight Display (PFD) includes an attitude indicator, a digitized representation of the air speed and altitude indicator (usually as a tape display), and a vertical speed indicator, among others. Click on the display in the Tupu visualization system to pop up a 2D panel to display the flight information of the flying aircraft.

Engine Indications and Crew Warnings (EICAS/ECAM) will allow the pilot to monitor values N1, N2 and N3, fuel temperature, electrical systems, etc. The Flight Management System (FMS) is used to enter and check flight plans, speed control, etc. The Multi-Function Display (MFD) provides a visual area that can be used for flight information integration, engine monitoring, and flight parameter configuration. The Navigation Display (ND) shows current heading information and commands entered into the Flight Management System (FMC).

The application of aviation navigation can provide continuous safe and reliable technical services for the aircraft operating in the air. In the 1960s, the INS (Inertial Navigation System) with autonomous navigation capability was used in the aviation field. It can display the three-dimensional aspects of the aircraft (position, speed), and can also provide important information such as heading and attitude.

Air transportation is less than other modes of transportation in terms of transportation volume. The transportation mode of bulk cargo in my country is water transportation. With the in-depth integration of modern information technology, Internet of Things technology, artificial intelligence technology and other advanced technologies with traditional waterway transportation in safety supervision, operation services, ship management, port services, etc., smart transportation has become a reality. Combining Tupu software with GIS maps, according to environmental elements such as longitude and latitude information, underwater topography, water flow pattern, wind speed and direction, a three-dimensional dynamic navigation geographical environment integrating point-line-surface is constructed to ensure shipping safety.

The HT for Web GIS product supports the loading of different map tile services or data, 3DTiles format data of aerial oblique photography real scenes, and different GIS data such as urban buildings. With the technical advantages of seamless integration and other technical advantages, the massive POI data, traffic flow data, planning data, current situation data, etc.

Today, aircraft designs are largely based on fully digital "glass cockpits," incorporating GPS receivers into the glass cockpit. Traditional gyroscopes have also been replaced by electronic heading and attitude reference systems (AHRS) and air data computers (ADCs), increasing reliability while reducing cost and simplifying maintenance.

The glass cockpit uses the flight management system to display flight information and displays different data on demand through the multi-function display. Simplifies the pilot's control and navigation of the aircraft, allowing the pilot to focus on the most relevant information. Combine big data, cloud computing and other technologies to achieve digital and green flight in the general aviation industry.

Since the "Thirteenth Five-Year Plan", general aviation and transport aviation have been "flying on both sides", and emerging business forms represented by low-altitude tourism and recreational flying have flourished, and the application scope and field of UAVs have also continued to expand.

At the end of the "Thirteenth Five-Year Plan", the fuel efficiency level of China's civil aviation has increased by nearly 30% compared with 2000, and the cumulative carbon dioxide emission has been reduced by about 360 million tons; the electrification rate of China's airports is nearly 60%, and the proportion of new energy vehicles in the field has reached 16%. The installation rate and utilization rate of alternative equipment exceeded 95%, and the annual power generation of the airport photovoltaic project exceeded 20 million kWh.

With the goal of carbon peaking and carbon neutrality, not only civil aviation is reducing carbon, but the transportation industry has also made many carbon reduction attempts after the deep integration of digital technology. Focusing on application fields such as the Internet of Vehicles, Internet of Flights, and smart ports and shipping, it has carried out industry explorations of smart transportation such as smart driving and smart airports.
