Specialised Imaging reports on how the Institute of Astronautics, Technical University of Munich, Germany has used a SIM-X ultra-high speed framing camera to record high resolution images of hypervelocity impacts on granular media samples with different bulk densities. UDRI's hypervelocity impact facility has 2 two-stage light-gas gun ranges for hypervelocity testing at velocities up to 24,600 ft/sec (7.5 km/sec). ► Performance evaluated in 66 hypervelocity impact tests. The Hypervelocity team, including ERC’s finest, assesses the protective armor by using two-stage light gas guns (LGG). This paper was presented during the 62nd IAC in Cape Town. DebriSat Hypervelocity Impact Test E. Marshall Polk United States Air Force and Brian E. Roebuck Aerospace Testing Alliance August 2015 Final Report for Period 1 – 15 April 2014 Statement A: Approved for public release; distribution unlimited. 8 MMOD Hypervelocity Impact Testing & Piggyback Sensing UDRI Hypervelocity Launch Capabilities Projectile sizes range from 1.5mm to 12.7mm for Range 4 (20mm launch tube) two-stage, light-gas gun. ► Potential weight savings of over 47% achievable. I would like to subscribe to Science X Newsletter. The results of this study identify materials and structures of interest for further, more in-depth, impact investigations. Learn more. NASA.gov brings you the latest images, videos and news from America's space agency. Once a targeted material reaches a point where it is ready for impact analysis, HITF personnel team up with White Sand Test Facility’s (WSTF) Hypervelocity Impact (HVI) test team for ballistic testing. The Note. Your friend's email. Hypervelocity impact testing was carried out at the University of Kent at Canterbury’s Light Gas Gun facility [10]. In our laboratory, we carry out tests that are key to understanding the behaviour of materials subjected to hypervelocity impacts. A red color indicates high impact risk from MMOD, and blue color indicates low impact risk. If you know your browser is up to date, you should check to ensure that To design effective shielding for spacecraft and to evaluate the risk posed by orbital debris and meteoroids, we must be able to perform tests in the laboratory. Projectile impacts from even seemingly harmless objects like a piece of foam or a bird can result in a catastrophic event. 20/02/2018 24866 views 30 likes 390480 ID 00:00:05 Like. s −1 are used to compare the performance of Whipple shields integrated with layers of metallic glasses with a baseline target analogue of one of the shields similar to … Projectile sizes range from 0.6mm to 3.18mm for Range 8 configured as a three-stage, light-gas gun. To meet specific needs, we associate our expertise in physical testing, material characterization and numerical simulation to support you in the development of structures with higher impact resistance and which will generate less debris in the event of a collision. Thus, metals and fluids behave alike under hypervelocity impact. https://doi.org/10.1016/j.actaastro.2012.09.012. HYPERVELOCITY IMPACT TESTING OF CFRP/AL HONEYCOMB SATELLITE STRUCTURES Frank Schäfer (1), Roberto Destefanis(2), Shannon Ryan , Werner Riedel(1), Michel Lambert(3) (1) Fraunhofer EMI (Ernst-Mach Institut), Eckerstraβe 4, 79104 Freiburg, Germany, Email: schaefer@emi.fhg.de, ryan@emi.fhg.de, riedel@emi.fhg.de Applications for this facility include design and evaluation of orbital debris shielding, lethality/survivability for theater missile defense systems, and characterization of Kinetic Energy penetrator performance.

HyperVelocity Impact testing has some extreme requirements and presents us with the following challenges: An experimental hypervelocity impact campaign was performed at two different two-stage light gas guns which encompassed both normal and oblique impacts for a range of impact velocities and projectile diameters. The top performing candidate shield at the screening test condition was found to be a double-bumper configuration with a 0.25 mm thick Al3003 outer bumper, 6.35 mm thick 40 PPI aluminium foam inner bumper, and 1.016 mm thick Al2024-T3 rear wall (equal spacing between bumpers and rear wall). Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. Solar array coupons designed for the Space Station Freedom electrical power system were subjected to hypervelocity impacts using the HYPER facility in the Space Power Institute at Auburn University and the Meteoroid/Orbital Debris Simulation Facility in the Materials and Processes Laboratory at the NASA Marshall Space Flight Center.

Follow this link to skip to the main content, MMOD shield ballistic limit determination. Impact velocities and residual velocities were measured. The overall trend is that the near Earth orbital debris environment is gradually getting worse. To get the best experience possible, please download a compatible browser.
