Orbit uncertainty propagation through sparse grids
(Mississippi State University, 2011-04-29)
The system of sparse gridpoints was used to propagate uncertainty forward in time through orbital mechanics simulations. Propagation of initial uncertainty through a nonlinear dynamic model is examined in regards to the ...
Rans And Hybrid Rans/Les Computations For Three-Dimensional Wings With Ice Accretion
Computational investigations were carried out to evaluate the effectiveness and usability of hybrid RANS/LES techniques for predicting the unsteady separated flow over wings with ice accretion. RANS and hybrid RANS/LES ...
Solution adaptive meshing strategies for flows with vortices
(Mississippi State University, 7/8/2008)
Simulations were performed to evaluate solution adaptive meshing strategies for flows with vortices whose axes of rotation are parallel to the bulk fluid motion. Two configurations were investigated: a wing in a wind tunnel ...
Study Of Lunar Constellations For Situational Awareness And Surveillance
Lunar constellations providing the capabilities of situational awareness and surveillance for future mission operators are analyzed in this study. The use of specialty orbits, such as sun-synchronous and frozen orbits, are ...
Development Of A Proof-Of-Concept Backpackable Unmanned Aerial Vehicle
This thesis documents the design and development of a robust backpackable proof-of-concept unmanned aerial vehicle. The unmanned aerial vehicle?s design departs from existing configurations in utilizing a keel beam fuselage ...
An Assessment Of Flow Quality In An Open Test Section Wind Tunnel
The subsonic wind tunnel facility at Mississippi State University has been converted to an open test section configuration. An experimental setup was developed which is easily configurable to allow for further research. ...
Flexural bending test of topology optimization additively manufactured parts
The aim of this work is to model, manufacture, and test an optimized Messerschmitt-BölkowBlohm beam using additive manufacturing. The implemented method is the Solid Isotropic Material with Penalization of a minimum ...
Comparative assessment of human observation in virtual and physical reality
(Mississippi State University, 2019)
Virtual Reality (VR) is a computer-generated simulation of an environment that can be interacted with a seemingly real or physical way by a person using special electronic equipment. VR techniques have the potential to ...
A Study of International Space Station Ground/Crew Communication Methods with Applications to Human Moon and Mars Missions
The International Space Station utilizes many different forms of written and verbal communication between the flight crews and ground control personnel. This study analyzes the historical use of three regular communication ...
Initial design of a methane and oxygen rocket engine
(Mississippi State University, 7/9/2010)
The purpose of this study was to examine the possibility of methane as a replacement to traditional fuels. Methane provides several advantages over fuels such as hydrogen. The LABROC VI was used to examine the performance ...
