Aerospace Seat Design: Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA)

In the United States, the Federal Aviation Administration (FAA) sets the standards for aerospace seat design regulations through its Technical Standard Orders (TSOs) and Federal Aviation Regulations (FARs). By using FEA according to FAA, our engineers can simulate the structural behavior of an aircraft seat and predict its response to various loading scenarios, including vibration , fatigue life, crash and impact conditions.

In Europe, the regulations governing aerospace seats are defined by the European Aviation Safety Agency (EASA). These regulations are contained in the Certification Specifications for Large Aeroplanes CS-25, Amendment 16, which outlines the airworthiness standards that must be met for certification of large airplanes, including the design and testing of aircraft seats. The EASA regulations require that aerospace seats are designed to ensure the safety and comfort of passengers during all phases of flight. This includes requirements for seat strength and durability, flammability, crashworthiness, and emergency evacuation.

  • Simulation based design can be used to evaluate compliance with specific aerospace seat design regulations related to crashworthiness, such as the strength and durability of the seat frame, attachment points, and materials used in construction. For example, FEA can be used to simulate crash landing scenarios and analyze the seat’s ability to absorb and dissipate crash forces, as well as its ability to protect passengers from injury. The FAA has established standards for the structural integrity of seats, including the strength and durability of the seat frame, the attachment points to the aircraft structure, and the ability of the seat to absorb and dissipate crash forces.
  • FEA can also be used to optimize the design of aerospace seats to meet specific safety standards and regulations. By simulating different design configurations, engineers can identify the most effective design for meeting safety standards while also optimizing for other factors such as weight, cost, and passenger comfort.
  • Simulation based design can be used to evaluate the performance of individual components of an aerospace seat, such as seat belts and restraint systems. The FAA requires that all aircraft seats be equipped with a seat belt or restraint system that meets specific standards for strength, durability, and ease of use. These regulations ensure that passengers can be safely secured in their seats during takeoff, landing, and turbulence.
  • Vibration is also a critical design consideration for aerospace seats, as excessive vibration can lead to discomfort and fatigue for passengers. By simulating the dynamic response of the seat, our engineers can identify areas of the seat that are subject to excessive vibration and modify the seat design to reduce these vibrations. This can involve adjusting the geometry of the seat, modifying the damping characteristics of the seat structure, or using vibration-absorbing materials in the seat construction.
  • Finite element simulation can be used to simulate the cyclic loading conditions that aerospace seats are subject to, and predict the potential for fatigue failure. By using FEA, engineers can simulate the structural behavior of an aerospace seat over time, considering factors such as cyclic loading, material fatigue properties, and stress concentrations.

Rotors Aerodynamic Simulation via Coupled FEA (MBD)/CFD Method: Aeroelastic Behavior Assessment

The blade vortex interactions (BVI) generate high load peaks and represent one of the main noise sources of a helicopter. In contrast to the rotors the flow around the fuselage is basically incompressible and many helicopters have a blunt body with large flow separations behind the fuselage. Depending on the flight conditions there may be strong interactions between main and tail rotors, rotor head, fuselage and the empennage, e.g. the tail shake phenomenon which is mainly caused by separations behind the rotor head.

considering Creep-Fatigue interaction in high temperature simulations identifies whether fatigue and/or creep are the dominant damaging mechanisms, thus allowing re-design to focus on the relevant damage mechanisms and significantly reduce pre-service component testing.

Vibration Fatigue Finite Element Simulation: Time & Frequency Domain

Structural vibration can be a source for many product related problems; it can cause fatigue and durability problems as well as adverse reactions to the user or bystanders in the form of undesirable vibrations that can be felt or heard. As well, undesired structural vibrations can prevent products from operating as required and potentially becoming a safety concern.
