Micrometeoroid Fluence Variation in Critical Orbits Due to Asteroid Disruption
<p>Micrometeoroids and orbital debris (MMOD) is a growing issue with international importance. Micrometeoroids are naturally occurring fragments of rock and dusk that exist throughout the solar system. Orbital debris is human made material like rocket bodies, paint flakes, and the effluent of …

Hypervelocity Impact Analysis of Hybrid Nanocomposite Sensors for Inflatable Space Structures
… impact damage by micrometeoroid orbital debris (MMOD) traveling at velocities as high as 15 km/s (Lemmens, Krag, Rosebrock, & Carnelli, 2013). This work presents fabrication and testing of hybrid nanocomposites with carbon nanotubes (CNT) and coarse graphene nanoplatelets (GNP) as fillers and …

Numerical study of projectile shape effect on the bumper performance under hypervelocity impact
… against micrometeoroids and orbital debris (MMOD) is generally based on experiments and models involving spherical projectiles. However, observations of collision fragments from ground-based satellite impact experiments have shown that orbital debris are non-spherical in shape. To adjust …

Development and Characterization of Piezoresistive Nanocomposites for Sensing Applications
… habitat under Micrometeoroid and Orbital Debris (MMOD) impact, the sensitivity of the sensor with 3 mm impact holes is evaluated using four point probe electrical resistivity measurements. An array of these sensors when sandwiched between soft good layers in a space habitat can act as a damage …

Assessment of damage to thermal protection systems due to micrometeoroid and orbital debris impacts
Thermal protection systems for hypersonic vehicles are low- to zero-fault-tolerant. In order to understand the fault tolerance of this system, the number of impacts that cause mission failure due to micro-meteoroid and orbital debris damage is presented. This number differs based on the mission, so …

Kosmické smetí a jeho vliv na konstrukci družic
Bakalárska práca sumarizuje problém kozmického odpadu a jeho vplyvu na konštrukciu satelitov. Hlavným cieľom práce je spojiť teoretické poznatky získané skúmaním a experimentami s ich praktickou implementáciou v konštrukčnom prístupe zvanom „design for debris“. Práca sa v teoretickej časti venuje …
