NASA Opens LAVA CFD Tool to U.S. Aerospace Innovators

NASA has released the Launch, Ascent, and Vehicle Aerodynamics (LAVA) CFD framework to the U.S. aerospace community, enabling faster, GPU-accelerated simulations of air flow around rockets and aircraft. The tool, used for Artemis mission analysis and other high‑fidelity aero problems, now lets researchers and companies run NASA‑grade simulations on modest hardware, supporting safer launches and broader design optimization across the industry.

"The Aerodynamic Design of Land Speed Racers: Unveiling the Science"

Automotive engineer and YouTuber Matt Brown is designing an aerodynamic body for his land speed racer using Computational Fluid Dynamics analysis. His bare-framed car had a drag coefficient worse than an 18-wheeler, and was unstable at 157 mph. With the new streamlined body, he estimates a top speed of 265 mph running on two cylinders, and 325 mph at full power, a significant gain from slashing the drag coefficient from 0.825 to 0.12. The design process involved optimizing the nose and tail to minimize drag, and adding a fin for aerodynamic stability. Challenges lie ahead in constructing the design in fiberglass, but the simulations suggest a much faster performance when the car returns to the salt flats.

Ancient Collision Unearthed: Traces of Moon-Forming Impact Found in Earth's Mantle

A recent study suggests that a massive anomaly deep within Earth's mantle may be a remnant of the collision that formed the moon around 4.5 billion years ago. Using computational fluid dynamics methods, researchers discovered that the early Earth exhibited mantle stratification after the impact, with the upper mantle featuring a magma ocean created through the mixing of material from Earth and the proto-planet Theia, while the lower mantle remained solid and retained the composition of Earth. This finding challenges the traditional notion that the giant impact led to the homogenization of the early Earth and provides insights into Earth's internal structure and long-term evolution. The study also sheds light on the formation of the inner solar system and has implications for understanding the heterogeneity of Earth's mantle and the origins of Large Low Velocity Provinces (LLVPs).

Quantum Computing Advancement for Jet Engine Design Announced by NVIDIA, Rolls-Royce, and Classiq

NVIDIA, Rolls-Royce, and Classiq have designed and simulated the world's largest quantum computing circuit for computational fluid dynamics (CFD) using NVIDIA's quantum computing platform. The circuit measures 10 million layers deep with 39 qubits and will be used by Rolls-Royce to advance the development of quantum computing in aerospace, specifically for modeling the performance of jet engine designs. The breakthrough was made possible by NVIDIA's cuQuantum software development kit, which includes optimized libraries and tools to speed up quantum computing workflows.
