One of the greatest challenges facing the aerospace industry is improving the aeroacoustic noise generation of their products to meet today’s more and more stringent noise pollution standards. As flow-induced noise makes a significant contribution to the overall output decibels, it seems essential to understand how to optimize the aircraft design in order to minimize the flow-induced noise without impairing the general performance of the air-vehicle.
In today’s competitive climate, driven by climbing fuel costs and increasing demand for air travel, high-fidelity CAe is a key enabling technology for aerospace companies to develop innovative minimum structural weight designs while meeting the tight schedule and cost constraints of a typical production environment. It is imperative that the CAe capability is accurate, robust and efficient and that it easily fits into the current engineering design processes, producing high-quality results with minimum user efforts. With its unrivaled meshing technology, high-fidelity physics, intuitive user...
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.
