Coupled Aerostructural Modeling of Deployable Aerodecelerators for Mars Entry

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Radiation Database for Earth and Mars Entry

This lecture presents the general guidelines we have followed to build up an exhaustive and accurate spectroscopic database for radiative transfer in air and CO2-N2 plasma applications, including atmospheric entries. This High Temperature Gas Radiation (HTGR) database includes bound-bound atomic, diatomic and polyatomic (in particular CO2) transitions, bound-free transitions resulting from vari...

Find Life on Mars entry

Georgia Tech expects to compete in Find Life on Mars with at least two (and potentially four) robots operating as a cooperating group. Research at Georgia Tech and elsewhere has demonstrated the speed and robustness afforded by multiple robot cooperation (Balch et al. 1995a, Balch and Arkin 1995b). The robots, Nomad 150s from Nomadics Technologies, are pictured in Figure 1. The Nomad 150 is a h...

Atmospheric Modeling Challenges and Measurement Requirements for Mars Entry, Descent and Landing

Introduction: Successful aerobraking, aerocapture, and entry, descent, and landing (EDL) at Mars requires knowledge of the nominal atmospheric density as well as mesoscale and local weather conditions. Whether aerobraking at altitudes of the order 100 km, aerocapturing at 30-50 km, or performing an EDL sequence where maximum aerodynamic loads occur near 40 km followed by terminal descent to the...
