Pipistrel: flying straight from simulation to production
The ESTECO optimization technology as a way to skip any prototype phase for a hybrid-electric aircraft propeller Pipistrel, an aviation & aerospace company based in Slovenia, relied on ESTECO Technologies to design the propeller for a highly efficient, hybrid-electric aircraft. The work was part of the EU-funded project MAHEPA (Modular Approach to Hybrid Electric Propulsion Architecture), that had the aim of advancing two variants of a low emission, serial hybrid-electric propulsion architecture to TRL (Technology Readiness Level) 6. The modeFRONTIER process automation and optimization software allowed automation in the simulation process and identification of innovative and optimized designs in a limited time. Challenge Engineers at Pipistrel had the challenge to design a propeller, driven by hybrid-electric propulsion system taking into account the different conditions the aircraft meets during the four flight phases: takeoff, climb, cruise and descent. Considering speed, power and thrust requirements changing during the flight, the objective was to maximize takeoff thrust and recuperation power during descent and minimize power during climb and cruise phase. The optimization involved three stages: the preliminary propeller optimization, the airfoil optimization, and the final propeller optimization. ## Solution For this multi-phase optimization project, Rok Lapuh and David Eržen, aero-dynamics engineers at Pipistrel, used modeFRONTIER coupled with CHARM (Comprehensive Hierarchical Aeromechanics Rotorcraft Model) and XFOIL, an interactive program for the design and analysis of subsonic isolated airfoils. Benefiting from the ESTECO process automation technology, Pipistrel could automate the simulation workflows, simultaneously evaluate thousands of designs and identify innovative optimized results. This process was conducted in a fully autonomous way leaving Pipistrel’s engineers the task to select the most appropriate design. With the first propeller optimization, Pipistrel optimized the chord and twist distribution to get the maximum thrust and minimum power for a given set of airfoils. The results were then used as requirements for the airfoil optimization. The design team used modeFRONTIER to design the airfoil under specific geometry constraints (thickness, cur- vature or leading-edge radius), while increasing the lift and reducing the drag. They started a Design of Experiments phase and then used the HYBRID genetic algorithm to successfully run the airfoil optimization and get the Pareto front with the optimal designs. At last, they used the optimum airfoil for the final propeller optimization. With the ESTECO optimization algorithms, engineers at Pipistrel could evaluate almost five thousand designs in a limited time and increase the thrust by 30% during takeoff. ## Benefits Before using modeFRONTIER, Pipistrel went through a manual process to simulate multiple designs and choose the preferred one. With the introduction of ESTECO Technology, Pipistrel engineers not only were able to automate this process, but could evaluate options not considered otherwise. “modeFRONTIER optimization technology gave me the opportunity to think outside of the box - said Rok Lapuh, Aerodynamics Engineer at Pipistrel - We could find a design that is completely different from what we’re used to, but that may work even better”. They also dramatically reduced the go-to-market time as they moved from simulation directly to the production. “We trust the results we get with modeFRONTIER so much that we don’t expect we’ll require a prototype - said David Eržen, Aerodynamics Engineer at Pipistrel - We go straight into production”.

Optimizing a perfect race engine. ESTECO Academy Design Competition winner
modeFRONTIER enabled Michael Bambula of the University of Florida to run the workflow, integrate third-party software, automate the design exploration process and perform post-process analysis. The winner, Michael Bambula of the University of Florida, presented a top-notch design project, in which he achieved significant performance improvements (64.2 hp @16500 rpm) while developing a complete model for a Moto3 bike and realistic simulations that also considered the specifics of the race track. Organized in partnership with Aprilia Racing and Gamma Technologies, the competition was open to teams of undergraduate and graduate engineering students. The challenge was to improve the design of a 4 stroke single cylinder engine through multidisciplinary optimization (using modeFRONTIER) and 1-D simulation of the engine system with GT-SUITE. The competition award included an internship opportunity at the APRILIA Racing team, which counts several World Championship Awards. The goal of the project was to maximize engine power. Due to the constrained engine architecture, an optimization of the Intake/Exhaust system was performed. Gamma Technologies supplied a set of simulation tools (GT-Suite) to develop the 1-D model of the high-performance engine. Various aspects of the base engine architecture were constrained such as Bore, Stroke, Con Rod Length, Engine Speed, Max Valve Diameters, Max Valve Lift, Max Throttle Diameter, Max Compression Ratio, Non-variable Cam Timing, and Naturally Aspirated. Considering these constraints, the optimization of the cylinder filling (Wave Dynamics) was seen as the logical design direction. modeFRONTIER workflow was used to automate the design exploration process and integrate Excel and GT-Suite for computing lifts value intake and exhaust valve lift profiles and simulating the engine power output. During the development of the 1-D Engine Model there were inherently many unknowns, therefore Michael made assumptions supported by rigorous research. The design variables related to the intake/ exhaust system were automatically found by modeFRONTIER to optimize the output results: sum of engine power across engine speeds speeds from lowest to highest respectively (11500 rpm to 17500 rpm). “modeFRONTIER ran 1000 different designs that varied the input parameters. The Hybrid Algorithm did an amazing job at finding the optimum solutions based on the objective of maximizing the engine power” said Michael Bambula, University of Florida Racing Team. “The analysis went beyond just determining the most powerful engine”, continued Bambula, “in fact the final objective, aimed at determining whether a certain design is sufficient for motorsports, was to compare it to lap times. This is why it was decided that the final group of optimum results from modeFRONTIER would be simulated in OptimumLap software considering, among other assumptions, a Moto3 motorcycle model traversing the Phillip Island Grand Prix Circuit in Australia”.

Takenaka Corporation: from Integration to Collaboration in the simulation process
Discover how designers, engineers and managers benefit from ESTECO Technology to simplify their DESIGN&BUILD process. Using VOLTA simulation process & data management, and design optimization capabilities, they collaboratively assessed the performance of structural elements of a new company building to maximize office space capacity. ## Why Design&Build and Simulation Process and Data Management Collaboration between design and construction has traditionally been playing an important role in the Architecture, Engineering, and Construction (AEC) industry. Takenaka Corporation, one of the top construction companies in Japan, ensures certified process and construction quality at the highest levels with its integral DESIGN&BUILD system. This methodology integrates architecture, building technology, and construction in a unified flow of work from concept through completion, replacing the traditional approach where the design and construction phases of a building project are carried out in a sequential manner. The DESIGN&BUILD system leads to many advantages: effective communication, unified quality, effective timing and cost overruns, and reduced completion time. In fact, architects and engineers collaborate with each other, share data, and are updated on various requirements to deliver innovative building solutions and meet clients’ expectations. When Takenaka Corporation embraced the DESIGN&BUILD system, it looked for a reliable Simulation Process and Data Management (SPDM) platform. That is why they partnered with ESTECO to simplify the whole simulation design process, manage a huge amount of data across teams, and shorten product development time. Designers, engineers and managers involved in the architectural projects access ESTECO VOLTA from a web browser and intuitively interact with the simulation process. From running 3D building simulations to applying design optimization techniques, analyze results and share data on the internal cloud for collaborative decision making. ## Expanding 3D building modeling and design optimization techniques across the enterprise Conducting manually parametric studies on 3D building models can become a time-consuming process leading to delays in project schedules. Overcoming these challenges for designers and engineers at Takenaka Corporation translate into an extensive use of ESTECO process automation, integration, and design optimization technology to significantly accelerate the architectural simulation design process. By combining modeling solvers as Rhino3D/Grasshopper, Abaqus, Midas iGen, or other in-house design software in modeFRONTIER powerful workflow, they can execute complex simulation chains and evaluate thousands of complex geometries in a short time. On top of that, applying ESTECO state-of-the-art design exploration and optimization algorithms to assess the correlation between several requirements (room size, thermal comfort, structural design to name a few) and maximize the building performance. At Takenaka, they had to make a step forward to expand the usage of 3D building modeling and design optimization techniques across teams with different expertise. Indeed, designers and engineers usually perform simple data analysis and are not necessarily confident in simulation and workflow set-up execution. Moreover, the DESIGN&BUILD methodology requires effective collaboration between the different actors involved in the simulation process to make changes and update their models for further analysis. This gap has been filled by scaling up modeFRONTIER desktop solution capabilities across the enterprise with the ESTECO VOLTA collaborative web platform. It enables simulation experts to create and make the simulation workflow ready to be executed via web. Then, designers and engineers can use these simulation models, apply design optimization techniques, and analyze results in the VOLTA platform. Since the simulation data are accessible in their internal cloud, it is easier for them to quickly interact with the simulation experts asking for updated CAD/CAE models when design changes are required. In the end, managers can log in to the VOLTA web platform, access product performance metrics, and monitor the whole simulation product development advancements. This scenario has been successfully applied in the early design phase of a new office building project. VOLTA made simulation usable by different teams to optimize structural elements in order to guarantee maximum office space capacity. Use case: rationalize the slab shape of an office building with VOLTA web collaborative platform Expanding the usage of simulation and optimization became a true fact when Takenaka’s designers and engineers had to collaborate in order to assess the performance of structural elements for a new office building. The subcontracted project required to drastically reduce the number of columns to make the most of the office space. However, the expected distance between the columns is about 17 meters, which is quite a lot according to the Japanese regulations. This has an unavoidable impact on the flat surface of a slab, a common structural element used to construct floors and ceilings. The slab needs a proper curve in order to guarantee the stiffness. Although, a side effect of the increased curvature may unbalance the floor forces and cause local additional bending moments. The solution is not just filling the curved slab shape, rather including massive amounts of ribs in some areas. To achieve this, the company’s designers and engineers combined the use of 3D building modeling techniques with ESTECO VOLTA collaborative web platform to explore reasonable volume amounts and coverage of the slab. First, they used Rhino3D/Grasshopper to create and model the shape of the office building and then converted it (in Grasshopper) to be meshed in Midas iGen to perform structural analysis. In the end, the several outputs from finite element analysis such as maximum displacement and the stress were extracted by using a python script. The interaction between the different simulation solvers was automated in the modeFRONTIER workflow coupled within the ESTECO VOLTA platform environment. This enabled simulation experts to upload the modeFRONTIER workflow and execute it through a web interface. Then, the structural engineers benefited from the VOLTA Advisor, a web environment for advanced post-processing and data visualization, to assess the simulation results from the finite element analysis model and validate the deformed shape of the all structure. For the same project, they also performed additional analysis through the VOLTA Planner dashboard, a modular interface to apply several optimization strategies in an intuitive way. This allowed them to easily create new simulation plans, change parameters bound, objectives and constraints with the aim of finding the best designs with minimized both the building weight and the maximum displacement of slab. “Thanks to the VOLTA HPC & Cloud capabilities, we were able to evaluate more than 700 designs in just four days. The VOLTA Player interface allowed to execute these computational heavy multi objective optimization analysis on the cloud without having to think how resources are used remotely”. Toru Inaba, Computational Design Group at Takenaka Corporation, also said that one of the key benefits of using VOLTA is to make simulation data accessible to a broader team of designers and engineers. “In particular,” concluded Toru Inaba, “our simulation experts could share the best practices on how to use the VOLTA Advisor, the web environment for advanced data analysis and visualization, with the structural engineers. The VOLTA web platform and its apps enabled us to truly democratize our DESIGN&BUILD simulation process. Designers and engineers can now access to the simulation results in one click and collaboratively take decisions without only relying on siloed reports of data”.
