OPTIMAD Engineering is involved in several publicly funded research projects in Aeroelasticity, Aerodynamics, Shape Optimization, Energy Efficiency, High Performance Computing (HPC) and Computational Fluid Dynamics (CFD) domains. A list with brief descriptions of the research projects is provided here.
 

European research projects

Research Projects: AEROGUST | Aeroelastic Gust Modelling

The AEROGUST project aims to carry out research into gust loads prediction. The methods currently used in gust loads processes within the industry are based on linear methods, corrected with experimental data. This makes it difficult to rapidly assess adaptations of designs and places a limitation on innovations such as using more flexible materials and novel configurations, for which the linear assumptions may not be valid.

Being a follow-up to the successful FFAST project, OPTIMAD will continue the collaboration with INRIA and other partners, in order to develop an efficient hybrid Eulerian-Lagrangian simulation paradigm, particularly suited for gust-structure interaction. Within this framework, the reduced order models developed in FFAST will be enhanced in order to account for non-linear structural behaviour.

SOUTH Clouds | Shape Optimization under Uncertainty through HPC Clouds

Fortissimo is a collaborative research project with the aim of promoting European SMEs to be more competitive through numerical simulations on HPC cloud architecture.
Within the SOUTH experiment, together our partners University of Strathclyde, Automobili Lamborghini Spa and CINECA, we want to implement a highly automatized prototype platform for shape optimization.
This toolkit, based on the open-source DAKOTA environment, will be augmented with
i) an abstraction layer, which allows an optimal automatic setting of the optimization algorithm,
ii) a geometrical engine based on CAMILO, which consents an easy and intuitive parametrization of complex geometries and
iii) a top-level graphical user interface will be implemented in order to control easily the entire work-flow.

Furthermore, a series of standard interfaces will be defined and made public,, which will permit the end.user to attach his favourite CAE software already available in the selected HPC infrastructure (e.g. made available through other Fortissimo experiments.).
The SOUTH platform will be demonstrated on an aerodynamic CFD shape optimization provided by the higher-performance sport cars industry.

Research Projects: FFAST | Future Fast Aeroelastic Simulation Technologies

The FFAST research project aims to develop, implement and assess simulation technologies to accelerate future aircraft design. These technologies will demonstrate a step change in the efficiency and accuracy of the dynamic aeroelastic “loads process” using unique critical load identification methods and reduced order modelling. The outcome from the project will contribute to the industrial need to reduce the number of dynamic loads cases analysed, whilst increasing the accuracy and reducing the cost/time for each unsteady aeroelastic analysis performed compared to the current approach.

Within the project, OPTIMAD developed in collaboration with INRIA a new simulation technology based on domain-decomposition, where in crucial parts of the flow domain canonical high-fidelity models are employed, whereas in less critical regions reduced-order models based on proper orthogonal decomposition are used. This technique reduces the computational cost as much as possible, while it ensures the accuracy of the result, resulting in a robust over-all approach.

Follow-up:
The techniques developed of FFAST have been successfully implemented in the aerodynamic design loop at Automobili Lamborghini Spa. Results have been presented at Aerovehicles1 conference in Bordeaux (http://aerovehicles1.sciencesconf.org)!!

Research Projects: ALEF | Aerodynamics loads extimation at extremes of the flight envelope

The scope of ALEF research project is to enable the European aeronautical industry to create complete aerodynamic models of their aircrafts based on numerical simulation approaches within the respective development process. I.e. ALEF will kick-off a paradigm shift from confidence in experimentally measured loads to greater confidence in computational results especially at the extremes of the flight envelope.

OPTIMAD contributed to the project by deriving reduced-order models for the interaction between wing and tail. At the extremes of the flight envelope the flow is often seperated at the wing and unsteady structures might impinge on the tail reducing its efficiency. Due to a large number of wing/tail configurations a huge test-matrix needs to be verified during design. OPTIMAD developed models, which may decouple the effects of wing and tail and hence reduce significantly the number of simulations needed.

National research projects

The CAST (Configurazioni AeroTermodinamiche per Trasporto Spaziale) research project aims at the development of integrated framework using experimental facilities and numerical tools, in order to predict complex aerodynamic, thermodynamic and aero-acoustic phenomena with a strong focus on industrial applications.

OPTIMAD as a sub-contractor of the team of the Politecnico di Torino and in collaboration with CIRA, has been in charge of the development of a full-implicit scheme in order to accelerate convergence of simulation tools.
Strong emphasis has been put on the robustness of the scheme as well as on the memory consumption, leading to a Jacobian-free Newton method, preconditioned with multi-grid and using multi-level continuation.

Research Projects: DRAPO | Energy efficiency and recovery in vehicles

The scope of the DRAPO’ research project is to develop innovative components and systems in order to provide efficiently all energy based functionalities of the vehicle in order to reduce energy consumption and CO2 emissions by 25%.

Within the project a technology demonstrator will be realized in order quantify experimentally the impact of the re-designed systems and of the optimized components on the over-all energy consumption.

OPTIMAD is working in close collaboration with the Centro Ricerche FIAT in order to reduce the aerodynamic drag by applying active & passive flow control devices.

The STEPS and STEPS2 research projects intend to produce a series of technological demonstrators (both virtual and physical) finalized to the development of systems for soft landing (lander) and surface mobility (rover) applicable for both robotic and human mission. This project envisages the realization and utilization of a set of laboratories equipped for tele-operations, of tools devoted to the concurrent design, simulation and virtual reality and of Moon and Mars simulated environments.
OPTIMAD operates within the Ablative Materials and Aerothermodynamics work package where two are the main objectives: a) development of an advanced composite material as core of an ablative Thermal Protection System for Mars entry missions and b) development of an integrated code simulating the material behavior during an entry path and the shape optimization of TPS.
