This book was released on 2018-06-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft operating in low earth orbit face a significant orbital debris impact hazard. Of particular concern, in the case of the Space Shuttle, are impacts on critical components of the thermal protection system. Recent research has formulated a new material model of reinforced carbon-carbon, for use in the analysis of hypervelocity impact effects on the Space Shuttle wing leading edge. The material model has been validated in simulations of published impact experiments and applied to model orbital debris impacts at velocities beyond the range of current experimental methods. The results suggest that momentum scaling may be used to extrapolate the available experimental data base, in order to predict the size of wing leading edge perforations at impact velocities as high as 13 km/s.Park, Young-Keun and Fahrenthold, Eric P.Johnson Space CenterHYPERVELOCITY IMPACT; CARBON-CARBON COMPOSITES; LEADING EDGES; SPACE SHUTTLES; SPACE DEBRIS; THERMAL PROTECTION; THREE DIMENSIONAL MODELS; FINITE ELEMENT METHOD

Available in PDF, EPUB and Kindle. Book excerpt: During 2003 and 2004, the Johnson Space Center's White Sands Testing Facility in Las Cruces, New Mexico conducted hypervelocity impact tests on the space shuttle wing leading edge. Hypervelocity impact tests were conducted to determine if Micro-Meteoroid/Orbital Debris impacts could be reliably detected and located using simple passive ultrasonic methods. The objective of Target Fg(RCC)-2 was to study hypervelocity impacts through the reinforced carbon-carbon (RCC) panels of the Wing Leading Edge. Fiberglass was used in place of RCC in the initial tests. Impact damage was detected using lightweight, low power instrumentation capable of being used in flight.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from arc jet tests conducted at the NASA Johnson Space Center on reinforced carbon-carbon (RCC) samples subjected to hypervelocity impact. The RCC test specimens are representative of RCC components used on the Space Shuttle Orbiter. The arc jet testing established the oxidation characteristics of RCC when hypervelocity projectiles, simulating meteoroid/orbital debris, impact the RCC material. In addition to developing correlations for use in trajectory simulations, we discuss analytical modeling of the increased material oxidation in the impacted area using measured hole growth data. Entry flight simulations are useful in assessing the increased Space Shuttle RCC component degradation as a result of impact damage and the hot gas flow through an enlarging hole into the wing leading-edge cavity.

This book was released on 2018-06-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: An improved hybrid particle-finite element method has been developed for hypervelocity impact simulation. The method combines the general contact-impact capabilities of particle codes with the true Lagrangian kinematics of large strain finite element formulations. Unlike some alternative schemes which couple Lagrangian finite element models with smooth particle hydrodynamics, the present formulation makes no use of slidelines or penalty forces. The method has been implemented in a parallel, three dimensional computer code. Simulations of three dimensional orbital debris impact problems using this parallel hybrid particle-finite element code, show good agreement with experiment and good speedup in parallel computation. The simulations included single and multi-plate shields as well as aluminum and composite shielding materials. at an impact velocity of eleven kilometers per second.Fahrenthold, Eric P.Johnson Space CenterSIMULATION; HYPERVELOCITY IMPACT; ALUMINUM; FINITE ELEMENT METHOD; COMPUTER PROGRAMS; KEVLAR (TRADEMARK); SHIELDING; SPACE DEBRIS; COMPUTATION; HYDRODYNAMICS; IMPACT VELOCITY; LAGRANGIAN FUNCTION; METAL MATRIX COMPOSITES; PARALLEL COMPUTERS
