Operational Requirements Analysis for Electric Vertical Takeoff and Landing Vehicle in the Brazilian Regulatory Framework

Air passenger transport is expected to change, in the next years, the urban air mobility (UAM) environment. New technologies are enabling the introduction of a new concept of aircraft, referred to as electric vertical takeoff and landing vehicle (eVTOL), with vertical take-off and landing capability, distributed electric propulsion system and low noise level compared to helicopters. This article presents an analysis of the Brazilian Civil Aviation Regulations (RBAC) No. 91 and 135, which address the minimum requirements for commercial operations of commuter and on-demand public passenger transport with airplanes with up to 19 seats. The objective of this article is to identify the technical and regulatory barriers to initiating the eVTOL operation in Brazil and to validate the current operational air traffic rules. After the analysis of the operational requirements and the current Air Traffic Management (ATM) infrastructure for helicopter operation, the minimum required and recommended navigation, communication and surveillance equipment are identified, as well as the main operational limitations for the operation of this type of aircraft in transporting passengers. This analysis is just the beginning of a broader study and there are many challenges to support an increased eVTOL operations.

Design of Underwater Welding Robot Used in Nuclear Plant

Through the analysis of operational requirements and environmental characteristics of nuclear power plant pool, we propose the design of underwater welding robot and establish the 3D model. Then, we introduce special functions and system composition of the robot in detail. After that, we propose the cooperation of the moving system and operating system, for the reason that the center position of gravity and buoyancy change when the operating system moves. Finally, we simply introduce control system components, control strategy and simulation results of the robot.

Design of the Control System for Fully Automatic Steel-Tube Molding Machine

In order to develop the control system for fully automatic molding machine which runs stable, reliable and high-automatically, its operational requirements analysis are studied deeply, based on the analysis of present research and development situation on domestic and foreign molding machine, this paper analyses its mechanical structure, working principle, hydraulic system. Finally, the author designs the FX2N PLC control system and briefly describes designing method and characteristics of hardware and software, which solves the problem: the low efficiency of domestic steel automatic stacker molding, collision quality loss and coordination of multiple devices in transit.

An Electro-Optical Surveillance System Application for Ship Collision Avoidance

This paper summarises the concept of an electro-optical navigation aid complementary to the radar, SERVIOLA naval surveillance system, based on the exploration of the visible and infrared spectral environment surrounding a naval platform by video cameras. The paper covers the system design methodology from operational requirements analysis, according the anticollision and surveillance missions, and the characteristics of the ship, through the required system performance and functions identification, down to the system components definition. As specific technical aspects, the paper discusses more in deep the proper selection of the infrared camera sensor for naval surveillance

4.2.2 System Engineering and KBS Development

AbstractThis paper discusses connection principles for methods and tools, between traditional Requirement Engineering and Problem Domain Analysis, in order to be able to manage every kind of requirement: functional, non functional, knowledge and rule based. This paper is based on studies carried out at NCS‐FRANCE, part of the Naval Combat Systems Group (NCS) of Thomson‐CSF.Thomson‐CSF has set up a common policy for System Engineering at the corporate level, which includes a method called MIST (“MŽthode d'IngŽnierie Systme Thomson‐CSF”), based on Draft MIL‐STD‐499B standard, and a tool which is RDD‐100TM. The additional work performed at Thomson‐CSF/NCS focuses on the analysis of operational requirements in the area of C3I systems. A Problem Domain Analysis approach appears to provide a promising solution. The method used by Thomson‐CSF/NCS in this area is KADS (Knowledge Analysis and Design Support), which is a conceptual modeling language stemming from European research projects. The tool which implements this method is OpenKADSTM.
