Engineers, Pilots Recall First Shuttle Launch on 25th Anniversary
Posted Wed April 12, 2006 @04:35PM

News There are several interesting recounts of the first space shuttle flight on April 12, 1981. The astronauts called the shuttle "A test pilot's dream" and several Boeing engineers describe their work developing the spacecraft and their feelings watching the first launch.

Zakrzewski describes the engineering work pretty complex for its time. “It was a very dynamic environment with the aerodynamics. When the forward booster separation motors would fire, the entire airflow around the Shuttle was disturbed considerably. The shock waves would come over the front nose of the Orbiter. It’s a very unpredictable environment. I don’t even think current Computational Fluid Dynamics programs could predict that environment adequately. So we had to do a lot of wind tunnel testing,” he explained.

Walt Gillette: Just Plane Genius

News A recent Business Week article chronicles the achievements of Boeing engineer Walt Gillette as he approaches retirement after 37 years designing aircraft. Included in the story is a recount of his early use of CFD:

Gillette used an analytical method called computational fluid dynamics (CFD) to crack the toughest design problems, including figuring out how to sling powerful new engines on the wings of a small 737. "Every time we tried to put one of those big fat nacelles [engine enclosures] close to the wing, we got terrible aerodynamic interference between the nacelle and the wing," Gillette recalled. "The extra drag made it unacceptable."

Events: Flow Induced Noise Simulation Seminar
Posted Tue April 11, 2006 @03:50AM

Announcements Do your products suffer from flow-induced noise? Are you facing severe noise problems due to rotating blowers, fans or HVAC systems? Would you like to reduce noise at the design stage or quickly model the noise radiated by an open sunroof, wing mirrors or A-pillars, in order to improve your product quality?

Join LMS for an aero-acoustics webinar to learn how the aero-acoustics simulation tools from LMS can help you evaluate the noise from unsteady flow phenomena like vortex shedding and turbulent boundary layers by coupling Computational Fluid Dynamics (CFD) methods with Computational Acoustics.

The seminar will be held twice on April 20th, 2006. Once at 10am Brussels time and again at 2pm Detroit time.

News A new Short Course on "Large Eddy Simulation (LES) of Transitional and Turbulent Flows: Numerical, Physical & Implementation Issues" will be held at Cranfield University on 6-8 November 2006.

The 3-day intensive Short Course is intended to cover in detail a number of LES issues including: numerical methods; subgrid scale models; validation; analysis of results; relation of numerical dissipation and subgrid scale models; implicit and hybrid LES methods; effects of initial and boundary conditions; and implementation in structured and unstructured grids.

Renault F1 Team and CD-adapco: Partners for Success

News In a now characteristic display of cool driving, Fernando Alonso took his tenth career victory in the Australian Grand Prix. Starting from third position on the grid, the Spaniard dominated an action-packed race that featured no fewer than four safety car periods. After taking the lead on lap 4 in a perfectly-judged maneuver on Jenson Button's Honda, the 24 year old World Champion only relinquished it during the first round of pit-stops, eventually piloting his R26 to the Renault F1 Team's third consecutive victory.

"The car was perfect," beamed the victorious Alonso, "there wasn't any risk of losing victory at any time".
