Automatic cabin virtualization based on preliminary aircraft design data

Preliminary aircraft design and cabin design are essential and well-established steps within the product development cycle for modern passenger aircraft. In practice, the execution usually takes place sequentially, with the preliminary design defining a basic cabin layout and the detail implementation following in a subsequent step. To enable higher fidelity assessment of the cabin early in the design process—for example by means of virtual reality applications—this paper proposes an interface, which can derive detailed 3D geometry of the fuselage from preliminary design data provided in the Common Parametric Aircraft Configuration Schema (CPACS). This is a key step towards integration of cabin analysis and preliminary design in automated collaborative aircraft design chains, not only in terms of passenger comfort, but also manufacturability or crash safety. Like the TiGL Geometry Library for CPACS, the interface presented acts as a parameter engine, which translates data from CPACS into CAD geometry using the Open Cascade Technology library. However, the scope of TiGL is expanded significantly, albeit with an explicit focus on the fuselage, by including more details such as extruded frame and stringer profiles and floor structures. Furthermore, advanced knowledge management techniques are employed to detect and augment missing data. For virtual reality applications, triangulated representations of the CAD geometry can be provided in established exchange formats, creating an interface to common visualization platforms. Additionally, a new evolution of the cabin definition schema in CPACS is presented, to incorporate models of cabin components such as seats or sidewall panels enabling immersive virtual mock-ups.

This paper riset aims to examine and analyze the legal rule regarding airlines for passenger aircraft in Indonesia is Law No. 8 of 1999 concerning Consumer Protection, Law no. 1 of 2009 concerning Aviation and Regulation of the Minister of Transportation No. 89 of 2015 concerning Handling Delays in Scheduled Commercial Air Transport Business Entities in Indonesia and Regulation of the Minister of Transportation Number 92 of 2011 amending the Regulation of the Minister of Transportation No. 77 of 2011 concerning the Responsibility of Air Transport Carriers. The factors causing the delay in departure at Kualanamu Deli Serdang International Airport are one of the factors of weather, and technical problems on aircraft but which are more often caused by weather, especially Kuala Lumpur is the hub airport (collecting airport) of several small airports where the weather can change at any time -Time and it is a thing that often happens in Kuala Lumpur. The responsibility of domestic airlines to aircraft passengers who experience delays in departure at Kualanamu Deli Serdang International Airport is to provide compensation and compensation in the form of soft drinks, snacks and heavy meals as well as compensation, depending on the type of delay according to the category, namely: Category 1, 30 to 60 minutes delay, Category 2, 61 to 120 minutes delay, Category 3, 121 to 180 minutes delay, Category 4, 181 to 240 minutes delay, Category 5, more than 240 minutes delay, Category 6, namely flight cancellations, then the airline is obliged to divert to the next flight or refund all ticket costs.

The fundamental constants of physics and the International System of Units

Air Canada managed to have a passenger aircraft run out of fuel in mid-air due to confusion about metric units (Stephenson in Mars climate orbiter mishap investigation board phase I report, NASA, 1999), and NASA lost an entire spacecraft due to a misunderstanding amongst engineers about the units used in the propulsion system design (Witkin in Jet’s fuel ran out after metric conversion errors, The New York Times, 1983). Measurements only make sense if the units are correct and well-defined. A unit of measurement is a definite magnitude of a quantity, defined by convention or law. Any other quantity of that kind can then be expressed as a multiple or submultiple of the unit of measurement. The Egyptians used the Farao as definite magnitude, while many years later, the french revolutionists introduced the earth as a reference and laid the foundations for the modern decimal system. Since recently, we have a truly universal and stable system that uses physics’s natural constants and laws to define the base units of measurement. This paper explains how this new concept works and how it is implemented in practice.

The research is designed to explore wide-body aircraft that are more suitable in 2035-2040. The innovative design of the wide-body aircraft adopts the form of the main passenger compartment and wing separation, the passenger compartment in the form of a single engine car through the rail transit and transfer car travel together. The transfer car delivers the two engine cars in turn to the aircraft, which is tightly connected to the rail structure by mechanical claws. Engine cars can split up at the transfer station, thus assisting in the diversion of passengers. The interior of the engine car has been optimized. A visual mask can be used for isolation has been designed for the seats. And a device is designed to lighten passengers’ legs to alleviate “economy class syndrome.” The corresponding data analysis used the mobile edge computing technology.
