Optimizing the remote sensing instrument of Taiwan’s FORMOSAT-8 satellite

Taiwan began designing and developing its first satellite in 1994 in collaboration with a U.S. space systems contractor. FORMOSAT-1 was launched in January 1999 and provided service until its retirement in 2004. FORMOSAT-2 was launched later in 2004, followed by FORMOSAT-3 in 2006. In 2010, FORMOSAT-5 passed design verification and now awaits deployment. FORMOSAT-5 will carry the first optical remote sensing instrument payload completely designed and developed by Taiwan itself.

Today FORMOSAT-8 is under development. This new satellite will inherit the experience from FORMOSAT-5 and will likewise carry an optical remote sensing instrument developed by Taiwan. Opto-mechanical systems integration will be led by the country’s Instrument Technology Research Center, with participation by the Opto-Mechanical Design Analysis (OMDA) Lab supervised by Professor Yi-Cheng Chen at Taiwan’s National Central University, which is responsible for weight reduction of the mirror supporting structure. To achieve the breakthrough improvements required in structural weight, the OMDA Lab is utilizing FEA-Opt Technology’s SmartDO design optimization, system integration and process automation software.

Maximizing aircraft economy through multidisciplinary winglet optimization

shutterstock_19549057
Winglets increase the lift generated at the wingtip by smoothing the airflow across the upper wing side near the tip. Winglets also reduce the lift-induced drag caused by wingtip vortices, improving the lift-to-drag ratio of the aircraft.

Executive summary—Wingtip devices are intended to reduce aircraft drag through partial recovery of the tip vortex energy. Fuji Heavy Industries (FHI) used Noesis Solutions’ Optimus to automate and couple FEM and CFD simulations to identify optimized winglet design configurations offering operational and environmental benefits. Optimus realized a 1.2% reduction in aircraft takeoff weight for a typical mission profile at 1G cruise speed. It achieved this by balancing the aerodynamic benefits and weight penalties of a passenger aircraft model integrating wing reinforcement to withstand winglet induced loads. Optimus’ design of experiments (DOE) and response surface modeling (RSM) capabilities helped FHI engineers understand the impact of winglet characteristics on aircraft performance up-front. Global design optimization enabled them to reduce the aircraft’s cruise drag by 4% and its takeoff weight by 676 kilograms, while respecting the shock induced separation (SIS) airflow constraint.

Last week’s case study looked at how Stanley Black & Decker’s DeWALT Industrial Tools brand optimized the efficiency and user comfort of its products at the same time as their robustness and durability with Altair’s AcuSolve, HyperMesh and HyperStudy software. This week’s story is how Stanley Black & Decker chose Altair’s HyperWorks Unlimited appliance to optimize its CAE processes for power tool design. The fully managed HPC system includes unlimited license for the HyperWorks suite of solvers, design exploration, meshing and visualization products as well as the PBS Works suite for HPC workload management.

Challenge: Improving the capacity for design optimization and innovation

As a global power tool leader, Stanley Black & Decker (SBD) is constantly seeking ways to maintain a competitive edge and bring better-performing products to market faster. In particular, when it came to optimizing the hammer mechanism design for their top-selling rotary hammers, SBD engineers knew they needed a CAE-based approach. Continue reading

Fan optimization in industrial electric power tools

Development of modern electric power tools for professional applications requires simultaneous attention to two sets of product attributes: those that determine a tool’s efficiency and user comfort, and those that determine its robustness and durability. To optimize both sets of attributes together, Stanley Black & Decker Deutschland GmbH relies on computer-aided simulation using Altair’s AcuSolve CFD flow solver in combination with its HyperMorph mesh manipulation tool and HyperStudy multidisciplinary design exploration, study and optimization software. In a paper presented at the 2013 European Altair Technology Conference in Turin, Italy, the company described how these simulations were used throughout the product development cycle—from the pre-development phase, through testing near-series prototypes, and beyond to improving designs based on product-failure returns.
