Using a File Format that Loads CFD Data 10 Times Faster

The Challenge Jared Gudenkauf is a CFD engineer (Jacobs engineering contractor) working in the fluid dynamics branch (ER42) of NASA Marshall Space Flight center in Huntsville, Alabama. Jared runs CFD in support of the Space Launch System (SLS), Mars Ascent Vehicle, and “Lunar Flashlight” Lunar Orbiter. His calculations for the SLS Ignition Over-Pressure/Sound Suppression water system involve two-phase flows. Jared’s main CFD code is Loci/CHEM, which he runs on the […]

Aerion Corp. Developing New Supersonic Business Jet

CFD simulations key technique for reducing airframe’s aerodynamic drag “It’s all about increased efficiency,” explained Spencer Fugal when describing the overall benefit his organization derives from its use of Tecplot Chorus. “The software allows us to automate the process of simultaneously comparing the results of different CFD simulations. This greatly accelerates the pace at which we can identify anomalies and validate or disprove our CFD results.” Fugal, a former Boeing […]

Building One of the World’s Most Efficient Electric Cars

Tecplot 360 helps Stanford University students optimize design of solar-powered car to compete in the Australian Outback’s World Solar Challenge The sun shines down upon the immense Australian Outback like nowhere else, drenching the land in solar energy that begs to be tapped. Where better to stage the World Solar Challenge, a design competition established to find the world’s most efficient solar-electric car? Every two years, some of the brightest […]

Supersonic Unmanned Aerial Vehicles Close To Becoming Reality

Researchers at University of Colorado developing supersonic UAV that’s fast, economical, and fuel-efficient It’s small. It’s fuel-efficient. It’s reasonably priced. And it’s fast. Supersonic fast. It is an unmanned aerial vehicle (UAV) that will fly at speeds approaching Mach 1.4 and faster than anything in the sub-50 kg vehicle category today, using an engine two to four times more efficient than any other in its class. Under development by researchers […]

Overcoming the curse of dimensionality in hypersonic design

Tecplot Chorus helps University of Colorado researchers demonstrate method for kriging surrogate models to increase accuracy of low fidelity results by an order of magnitude. May 2012 The decades-old quest to develop hypersonic vehicles powered by airbreathing1 engines for space exploration, defense, and air travel has yielded some promising results. Yet the goal of developing viable designs for commercial use remains elusive. Designing manned and unmanned vehicles for hypersonic speeds—anything […]

Continuum-Dynamics, Inc. Uses Tecplot 360 to Develop First Commercial Ship Air Wake Database for U.S. Navy Helicopter Flight Simulators

Addition of Disturbance Field Creates More Realistic Piloted Simulation Environment for Increased Safety and Lower Training Costs Flying a helicopter has often been compared to balancing on one foot while standing on a beach ball—and that’s just over land. Now imagine balancing on a beach ball that’s on a funhouse floor in the middle of a nor’easter. That’s what a landing at sea can be like. The pilot must put […]

NASA CFD Software Helps Quiet the Skies

Contributed by: Dr. Craig Hunter, NASA Langley When Denver International Airport (DIA) joined the nation’s commercial air transport system in 1995, property owners in rural Adams County, a community 15 miles east of DIA, were concerned about the increase in noise that accompanied the new airport. A quick remedy to DIA’s noise problem is re-routing arriving and departing aircraft around populated areas. As the nation¹s fifth busiest airport, however, DIA quickly […]
