A Study On The Micro Electro-Discharge Machining Of Aerospace Materials, Mychal-Drew Moses 2015 Western Kentucky University

A Study On The Micro Electro-Discharge Machining Of Aerospace Materials, Mychal-Drew Moses

Masters Theses & Specialist Projects

Electrical Discharge Machining (EDM) is a non-traditional machining process that uses hundreds of thousands of minute electrical sparks per second to machine any electrically conductive material, no matter the hardness or how delicate it is. EDM allows a much greater range of design possibilities, unconstrained from the traditional machining processes, in which material is removed mechanically by either rotating the cutting tool or the work piece. Shapes that were impossible to machine by any other method, such as deep, precision, square holes and slots with sharp inside corners, are readily produced. It provides accurate geometries in high- aspect ratio holes ...

The Openorbiter Cubesat As A System-Of-Systems (Sos), Sofiane Chaieb, Michael Wegerson, Jeremy Straub, Ronald Marsh, Benjamin Kading, David Whalen

Jeremy Straub

This paper discusses the use of the system-of-systems (SoS) methodology and SoS engineering (SoSE) to the challenge of the design and operation of a CubeSat-class spacecraft. It considers this in the context of one critical component system, the electrical power system (EPS) which interacts with virtually all other systems onboard the spacecraft. The spacecraft is also considered in the context of being a system-component of a larger mission system-of-systems. The efficacy of SoSE use for this endeavor is considered and recommendations are made for the use of SoS and SoSE by other small spacecraft and, more broadly, spacecraft developers.

Jeremy Straub

Pilotless aircraft known as Unmanned Aerial Vehicles (UAVs) have been used extensively for military and intelligence purposes. This includes situations where the mission area is too dangerous for a pilot to fly, the length of the mission is longer than a pilot could stay awake or aircraft are used as cruise missiles that crash into their target. With the decreasing cost and miniaturization of computers, it has become possible to build UAVs that are small and inexpensive making them accessible to businesses, law enforcement, hobbyists and the general public.

The Use Of Additive Manufacturing For Cubesat Design And Testing, Jeremy Straub, Ronald Marsh, Scott Kerlin

Jeremy Straub

In developing a small spacecraft, the integration of numerous systems in a small area is a key challenge. It is easy to overlook how various component parts will integrate or have multiple sub-groups utilize un-filled space without realizing that they are creating a resource conflict. Additionally, the manufacturability of the final design is a key consideration. For all of these reasons, developing low-cost and incremental prototypes is a engineering ‘best practice’ for small spacecraft development.
