Hypervelocity Impact Society

The Best Paper Award at HVIS2024 went to George Flynn and co-authors (M. Strait, H. Willman, A. Rolling, T. Pytel, H. Wheeler-Cooney, R. J. Macke,??and D. D. Durda) for their work on "Hypervelocity Impact of Three L-Type Ordinary Chondrites: a test of the variation of?β?and Q*D?with target porosity and strength"

Congratulations to Dr James Walker, the Society's newest Distinguished Scientist Awardee! Dr Walker is well known to many of you for his body of work in hypervelocity impact, numerical analysis, and penetration mechanics. His work has been widely applied in armor, planetary defense, and the Space Shuttle Orbiter return to flight program. Attendees at HVIS2024 were privileged to enjoy a keynote presentation from Dr Walker, recapping his many career highlights and achievements.

That's a wrap on HVIS2024! Thanks to everyone who attended the symposium in Tsukuba - we trust it was an informative and enjoyable time.

Specialised Imaging Limited will be exhibiting at HVIS2024. Specialised Imaging is an internationally renowned company dedicated to the design and manufacture of ultra-high-speed imaging systems for defense, industrial and scientific research applications. Specialised Imaging has been at the forefront of high-speed imaging innovation for the last twenty years and has successfully launched several innovative ultra-highspeed imaging solutions. Our commitment to development has enabled the company to establish a solid reputation in the high-speed camera market, with solutions such as the KIRANA – a true Ultra high-speed video camera capable of up to 7 million images/second at full resolution, and the SIM Framing camera capable of up to 1 Billion pictures/second. To provide complete solutions we have developed sophisticated triggering, lighting and optics and represent complementary imaging solutions manufacturers such as Optronis GmbH for Streak camera to provide an integrated framing and streak option. Make sure to stop by and talk to Specialised Imaging about your imaging goals during HVIS2024.

HVIS2024 is only a week away! The symposium includes technical oral presentations, keynote addresses, poster sessions, an excursion to the JAXA Tsukuba Space Center, and exhibits from event sponsors.

Can we reliably test how spacecraft hardware performs when impacted by debris at velocities over 10 km/s (22,000 mph)? At the 2022 Hypervelocity Impact Symposium Andrew Piekutowski and Kevin Poorman from the University of Dayton Research Institute received the Best Paper award for their work on developing UDRI's three-stage light gas gun, allowing repeatable testing with spherical projectiles up to 10 km/s (9.9 km/s is the fastest result they report in the paper). Here's how two-stage light gas guns work (courtesy of NASA - National Aeronautics and Space Administration). The team at UDRI, taking inspiration from some work at McGill University done back in the 1960's, added a third stage augmented acceleration cycle.

Next in our series of classic hypervelocity impact images. This one shows the impact crater in a monolithic aluminum alloy block created by a 1.2 cm diameter aluminium sphere impacting at 6.8 km/s normal to the target surface. A nominally identical projectile is shown sitting in the bottom of the crater for scale. The test was performed on a two-stage light gas gun at Fraunhofer EMI. The image is one regularly used by the European Space Agency - ESA to highlight the risk of debris impacts. #engineering #spacedebris #orbitaldebris #hypervelocity #impact

When it comes to space debris impact, there are a few common images that keep reappearing. Does this one look familiar? It has been tweeted by Neil DeGrass Tyson and has repeatedly done the rounds on Reddit, Facebook, and LinkedIn - racking up hundreds of thousands of comments and interactions. It's not comparing apples with apples though. On the left is a monolithic aluminum block that was impacted by a 14g cylindrical plastic (Nylon) projectile at approximately 6.5 km/s with normal incidence (i.e., at 90deg to the surface of the target). On the right is an aluminum honeycomb sandwich panel that was impacted by a 0.07g spherical aluminum projectile at 6.8 km/s with 45deg incidence. Both tests were conducted on NASA's two-stage light gas guns. #engineering #spacedebris #orbitaldebris #hypervelocity #impact
