Drone Aerodynamic & Acoustic Simulation Based Design
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Drone aerodynamic simulation is used to improve the aerodynamic performance and reducing the drag of drone. Objective of the simulation is to make accurate predictions of aerodynamic forces, Lift and Drag Coefficient etc. In the same time, we use the results of aerodynamic simulation for noise and acoustic design and optimization. Aerodynamics is at the core of all aerospace engineering programs. Enteknograte engineering team use coupled MBD and CFD to simulate any drone related problems in world-class simulation methods.
Ensure urban air mobility technology adoption and reducing noise using simulation-based design
For drone dynamics, the acoustics and noise challenge is to design disc loading, rotor tip speed, propeller interactions and vehicle scattering in such a way that the overall in-situ noise levels are reduced. It is a multidisciplinary issue, calling for the combined use of various simulation techniques.
- CFD simulation in coupled with advanced Acoustic solver to capture drone noise in different situation
- Investigate the effects of the rotor-on-rotor interaction, and presence and absence of the body
- Evaluate the sound scattering effects due to the presence of the drone body
- Effect of the urban environment on the noise
- Propeller interactions influence on the noise signature
- VTOL, e-VTOL and UAM – Urban Air Mobility
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.

Aerodynamics Simulation can cover the full speed range of low speed, transonic, supersonic and hypersonic flows as well as turbulence and flow control. System properties such as mass flow rates and pressure drops and fluid dynamic forces such as lift, drag and pitching moment can be readily calculated in addition to the wake effects. This data can be used directly for design purposes or as in input to a detailed stress analysis. Aerodynamics CFD simulation with sophisticated tools such as MSC Cradle, Ansys Fluent and Siemens Star-ccm+ allows the steady-state and transient aerodynamics of heating ventilation & air conditioning (HVAC) systems, vehicles, aircraft, structures, wings and rotors to be computed with extremely high levels of accuracy.

CFD Simulation for Thermal Comfort & Aeroacoustic analysis of HVAC components, fans, blowers and air channels
The passenger’s thermal and acoustic comfort is an essential design-criterion for the air-conditioning and customization of a cabin. In industry, engineers conduct costly and time-consuming test series with specifically built cabin mock-ups to obtain some information about the expected passenger’s sensation of comfort already in the design process.

Sound caused by pressure oscillation of fluid, such as wind noise, and sound caused by resonance can be predicted using Large Eddy Simulation (LES) and a weak compressible flow model. A Fast Fourier Transform calculation can be used within the CFD software to predict the frequency of noise. Predicting the noise generated by complex flows from steady CFD solutions allows us to study the noise generated by turbulent flows from CFD solutions.

Noise, vibration, and harshness (NVH) are critical factors in the performance of many mechanical designs but designing for optimum NVH can be difficult. While strength and durability limits are being pushed further and further, requirements for noise reduction are becoming more stringent. In addition, focus is increasingly being placed on transmission and powertrain noise because other sources could be reduced meanwhile.

Machine learning is a method of data analysis that automates analytical model building. It is a branch of Artificial Intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. With Artificial Intelligence (AI) applications in CAE, that is Mechanical Engineering and FEA and CFD Simulations as design tools, our CAE engineers evaluate the possible changes (and limits) coming from Machine learning, whether Deep Learning (DL), or Support vector machine (SVM) or even Genetic algorithms to specify definitive influence in some optimization problems and the solution of complex systems.

The sensitivity information comes directly from the flow field so the optimized shape is the one that fits the given flow best. Unlike traditional design methods that rely on trial and error between a given geometry and flow field predicted by CFD codes, we use 3D inverse design method starts by identifying what we want to do to the fluid flow in terms of 3D pressure field and mathematically derives the optimal geometry to achieve that outcome. This significantly reduces the time taken for each design.
