FEA & CFD based-Design Optimization of VTOL, e-VTOL and UAM - Urban Air Mobility

The VTOL, e-VTOL and UAM market is constantly changing and evolving, so maintaining a competitive edge both within the industry and supporting mission effectiveness requires significant research and development activities. Enteknograte offers the industry’s most complete simulation solution for vertical-takeoff-and-landing (VTOL) aircraft. Our research and development procedure has required a blend of qualities such as ambition, drive and commitment as well as more tangible assets such as specialist engineering skills, rapid development through simulation techniques, supreme electronics expertise and a ruthless quest for performance and reliability.

The level of partnership and support for Developing a leading edge VTOL, e-VTOL and UAM system FEA and CFD simulations that our customers get is just as important to us. We are investing time and resources to ensure customers receive support and service that is of the same, highest possible standards as the reliability and performance.

Increase efficiency, reduce noise, costs, and time-to-market of rotorcraft and eVTOL vehicles with an integrated design, simulation and optimization process

  • Leverage an integrated design and analysis process to develop preliminary VTOL aircraft designs that maximize propulsion efficiency in hover, maximize aerodynamic efficiency in cruise and minimize noise over the entire flight envelope.
  • Use high-fidelity fluid dynamics simulation in an optimization loop to maximize propulsion efficiency and minimize noise in hover.
  • Reduce blade-vortex interaction and loads acting on the control surfaces during conversion.
  • Design for low-noise manuevers.
  • Analyze the acoustic impact in a urban environment during take-off and landing.
  • Reduce product development costs and reduce time-to-market using digital simulations to predict performance early in the design cycle rather than physical tests in the late stages of development

Vibroacoustics performance assessment of aircraft panels in low, mid and high frequency regimes

A true VTOL system design has complex challenges, particularly designing for a high thrust for hover while also reducing drag for cruise. In simple terms, you are designing a helicopter and forward-flying aircraft in the same product.

Vibroacoustic (VA) characteristics, namely sound transmission loss, overall sound pressure levels of aircraft panels made up of different materials such as aluminum, composites and fiber metal laminates can be analyzed with optimization approach for aircraft panels.

The investigation involves modeling of aircraft panels using finite element method (FEM) for low frequency, Boundary Element Method (BEM) for mid-frequency and statistical energy analysis (SEA) in high-frequency bands. To obtain the VA characteristics of the panels, twin chambers, namely source and receiver are numerically modeled, and the panels are placed in between them. This numerical study helps in understanding the VA behavior of aircraft materials and also minimizes the cost and time involved in conducting experiments.
