Sikorsky Aircraft set out to explore an alternate method of predicting hub drag of production geometries based on numerical simulation. This method can provide a reasonable prediction of hub drag for different designs in a short time period, allowing easier optimization of component design in a production environment. This article showcases the application of CD-adapco’s unstructured Navier Stokes solver, STAR-CCM+, to the blind prediction of hub drag on two production rotor hub geometries, the S-92A hub and the UH-60A hub.
Develop an aircraft design concept and design aids/mockup that will illustrate that the key performance requirements stated in this document were met in addition to the mission success and safety of the occupants were ensured. Concepts can be demonstrated or illustrated in many ways – choose the most appropriate and cost eff ective (paper/pencil, trade studies, desk top models, charts, mini-demos, electronic simulations, analysis tools, etc.). Develop innovative concept ideas in an integrated fashion to show traceability to meeting the requirements – both stated and derived.”
The 2013-2014 AerosPACE course partners are The Boeing Company, Brigham Young University, Embry-Riddle Aeronautical University, Georgia Institute of Technology and Purdue University. Teams consisting of students from each university were asked to design, build and test a UAV that can monitor agricultural fields to improve crop yield. The UAV must meet various mission parameters.
AgustaWestland used STAR-CCM+ to accurately analyze the new exhaust design of the AW609 Tilt Rotor engine bay. The methodology established and validated in STAR-CCM+ can now be used to simulate additional fl ight conditions. Furthermore, changes to the new design can now be quickly assessed and validated through simulation, resulting in a shorter turnaround time and lower design costs. The solution methodology established at AW using STAR-CCM+ offers an effi cient way to improve the performance of the engine bay and to address future developments in exhaust design.
Numerical Simulation of Turbomachinery flows are among the most complex computations performed in the world of Computational Fluid Dynamics (CFD). CFD applied to Turbomachinery has come a long way from the inviscid 2D blade-to-blade methods of the 1960’s and recent developments have ensured that numerical simulation plays a major role in turbomachinery design. CD-adapco has more than 30 years of expertise in developing cutting-edge simulation capabilities for the turbomachinery industry, the most notable and recent of which is the Harmonic Balance (HB) method. To understand the need for...
Six months before launching the Learjet 60 AFL program, Raisbeck Engineering made a decision to stop outsourcing CFD and bring it in-house in an effort to expand hands-on knowledge, reduce development time, and increase control of priorities. After evaluating a number of options, Raisbeck Engineering decided to invest in STAR-CCM+ due to its ability to address all of Raisbeck's requirements.
Fifteen weeks! That’s all it took for a group of senior undergraduate students from the University of Washington’s Aerospace Engineering department to design, test, and build a commercial quality small Unmanned Aerial Vehicle (UAV) for research focusing on low-speed flight characteristics and engine noise-shielding of supersonic flight vehicle configurations.

For more than 100 years, ship designers have built ships using the evolutionary appproach - one small improvement per design generation. Within the last few years, CFD has provided a grounbreaking technology to enable the revolutionary approach - true optimization for every design generation. CFD has become a practical tool in almost every sense. This is true not just from the technical point of view, but from the business point of view as well. It enables a proactive approach to solving client problems, and provides the means to revolutionize a maritime industry that is traditionally...
Electric propulsion is on the verge of causing the biggest changes in aviation since the advent of the jet engine. At first glance, it may seem that the excessive weight (i.e. low specific energy) of today’s batteries limits electric aircraft to, at best, a few trivial niches. However, the different properties of electric propulsion compared to traditional combustion power, coupled with recent technology advances, promise to significantly relax typical design constraints for many aircraft configurations, which will allow for new types of aircraft that were previously impractical or impossible...
