This study aims to address the problem of attitude control of spacecraft in presence of thrust uncertainty, which leads to stochastic accelerations. Spacecraft equipped with electric propulsion and other low thrust mechanisms, ...

Experiments were performed on a slotted natural laminar flow airfoil, the S414. The slotted natural laminar flow airfoil concept was developed to satisfy design constraints of high maximum lift and low profile drag. A ...

The objective of this thesis is to develop a design method together with a design philosophy that allows the design of "subscale" or "hybrid" airfoils that simulate fullscale ice accretions. These subscale or hybrid airfoils ...

In this thesis, the hybrid approach has been applied to the development of inverse methods for the design of (1) multi-element airfoils for multipoint velocity and boundary-layer prescriptions and (2) airfoils to obtain ...

This study explores the Systems Engineering involved in creating an environmentally green system for transporting cargo using aircraft. The study looked at using hydrogen and the resulting infrastructure to allow the ...

Vortex structures observed in the shear layer were presumed to be the cause of large-scale pressure fluctuations upstream of reattachment at small angles of attack. Pressure spectra near reattachment exhibited wide bandwidth ...

The goal of this thesis is to identify potential Near-Earth Asteroids (NEAs) that are viable candidates for human exploration. The computational method incorporated to help identify these targets is the particle swarm ...

This thesis proposes an integrated simulation tool to evaluate the impact of future in-space additive manufacturing (ISAM) and recycling technologies on the responsiveness of an on-orbit servicing (OOS) infrastructure to ...

An improved collocation method is developed for a class of problems that is intractable, or nearly so, by conventional collocation. These are problems in which there are two distinct timescales of the system states, that ...

The University of Illinois has developed the IlliniSat-2 CubeSat bus, a generic scalable and modular design, utilizing commercially available off the shelf (COTS) parts. The Attitude Determination and Control System (ADCS) ...
