Finite Element VTOL, eVTOL & UAM
Vibroacoustics Performance Assessment
eVTOL (Electric Vertical Take-Off and Landing) & UAM (Urban Air Mobility): FEA & CFD Based Simulation for Ground Vibration Testing (GVT), Airworthiness Certification, Aerodynamics, Aeroacoustics and Crashworthiness
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.
