What is aircraft cabin crew uniform made of?5 answersAircraft cabin crew uniforms are typically made of textile materials that vary in flammability and safety features. Research indicates that flight attendant working clothes are often made of flammable materials, while galley curtain fabrics are designed to be self-extinguishing. Additionally, innovations in aircraft equipment include features like crew cabin tables with mechanisms for extension, retraction, and locking in place for space efficiency and reliability. Furthermore, aircraft designs may include crew quarters with adjustable seating arrangements for transitioning crew members between sitting and berthing configurations. Moreover, specialized seats for cabin crew in aircraft are designed with sliding mechanisms and curved rails to optimize space and comfort during flights.
What are the most common seating configurations found in family cars?5 answersThe most common seating configurations found in family cars include:
- A seating arrangement with at least one front seat and at least one rear seat, where the front seat is rigidly fixed to the vehicle and suspended, providing a free space underneath for the rear seat occupant to position their legs.
- A seating arrangement with a rail system that has lateral and longitudinal rails, allowing for the attachment of seating assemblies. These seating assemblies can transition between captains' chair, loveseat, and bed configurations, with articulating armrests.
- A seating arrangement featuring an electromagnetic array on the vehicle floor, which interacts with a chair base equipped with magnets. The array generates signals to impart a force on the chair in a determined direction.
- A seating arrangement with a base cushion, top cushion, and coupling cushion section, along with a coupling device for attaching a child seat. The coupling arm of the child seat can be coupled with the coupling device on the seat cushion section, and a guiding device is provided on the cover of the coupling cushion section.
- A vehicular seating suite configuration with vertically stacked seating suites, each having an angled seating surface and a vertical backrest. This configuration allows for both sitting and lying positions.
What are the materials used in interior design in automotive industry?5 answersThe materials used in interior design in the automotive industry include vegetable hemp fibers, thermoplastic plastic fibers, binders, weft-knitted fabrics made of draw textured polyester and textured polyamide yarn, natural fiber reinforcement, PP, ABS resin, light calcium carbonate, a toughening agent, an antioxidant, a lubricant, and PP-g-MAH, polyester needle-punched nonwoven fabric, and polycarbonate-based polyurethane resin, and a surface layer with a first plasticizer and a thermoplastic resin, and a base layer which is a polyurethane (PU) foam with a second plasticizer and a tackifier.
What are the design considerations for fuel cell electric vehicles?4 answersDesign considerations for fuel cell electric vehicles (FCEVs) include the integration of fuel cell systems with other components such as electrolyzers and solar power to fulfill fluctuating power demands. Energy management strategies (EMS) are crucial to optimize fuel cell service life and economy, with fuzzy control methods used to address power fluctuations. The use of Proton Exchange Membrane Fuel Cells (PEMFCs) can increase driving range and reduce pollution, but careful analysis of parameters such as stack voltage and current density is necessary. Fuel cell systems require subsystems for oxidant and fuel supply, heat and water management, power conditioning, and controls. Different combinations of energy sources, such as batteries, supercapacitors, and fuel cell systems, need to be considered for optimal performance.
How does the interior design of an intercity bus affect passenger comfort?5 answersThe interior design of an intercity bus significantly affects passenger comfort. Studies have shown that passengers have different attitudes and comfort perceptions, and therefore, attention should be given to designing the interiors of buses for long journeys. Factors such as physical comfort, accessories and other facilities, seating considerations, and space for movement play a vital role in passenger comfort. Additionally, the thermal comfort inside the bus is also important for the well-being of passengers. The design of the seats and headrests can greatly impact passenger comfort, with features such as adjustable angles and cushioning providing a more comfortable experience. Furthermore, the overall layout and arrangement of the interior space should be optimized to meet the aspirations of the commuters. By considering these factors and incorporating ergonomic principles, bus designers can enhance passenger comfort during intercity travel.
How is the cabin adopted and/or adapted for Formula Student?5 answersThe cabin in the formula student car has been adapted and designed to meet specific requirements. One paper describes a special cabinet that uses RFID cards and electromagnetic locks for unblanking and ensures the safety of the cabinet. It also allows for remote monitoring through the GSM network. Another paper discusses a retrench interior cabin that focuses on high space utilization and reducing the volume of the car. It achieves this by concentrating functions on a liquid crystal touch screen, reducing the degree of difficulty in driving and improving road traveling security. Additionally, a paper mentions a college student formula car enclosure structure that encloses the driver's body for absolute safety during high-speed runs, preventing serious personal damage from accidents. These adaptations and designs in the cabin aim to enhance safety, functionality, and comfort for formula student cars.
