Internet Enabled Remote Driving Of A Combat Hybrid Electric Power System For Duty Cycle Measurement, Jarrett Goodell, Marc Compere, Wilford Smith, Mark Brudnak, Mike Pozolo, Et Al.

Marc Compere

This paper describes a human-in-the-loop motion-based simulator interfaced to hybrid-electric power system hardware, both of which were used to measure the duty cycle of a combat vehicle in a virtual simulation environment. The project discussed is a greatly expanded follow-on to the experiment published in [1,7]. This paper is written in the context of [1,7] and therefore highlights the enhancements. The most prominent of these enhancements is the integration (in real-time) of the Power & Energy System Integration Lab (P&E SIL) with a motion base simulator by means of a “long haul” connection over the Internet (a geographical distance of …

One such technology is Space So- lar Power. (SSP) SSP technology involves generating power in space from the sun and beaming it via microwave radia- tion to a ground site for use. This method has immediate usability on Mars due to the minimal atmosphere, …

Cubesat Deployable Solar Panel System, Thomas Mcguire, Skye Leake, Michael Parsons, Michael Hirsch, Benjamin Kading, Jeremy Straub, David Whalen

Jeremy Straub

CubeSats are small spacecraft with a nominal size of 10 cm x 10 cm x 10 cm and a mass of 1.33 kg [1] (though some launch providers are now supporting expanded mass levels). While the CubeSat form factor has re-duced the time and cost of spacecraft development, the required resources are still beyond the grasp of many colleges and universities. The Open Prototype for Educational Nanosats (OPEN) aims to solve this problem. OPEN is an inexpen-sive modular CubeSat that can be produced with a parts budget of less than $5,000 [2]. The OpenOrbiter pro-gram is working to develop this …

Pattern Recognition And Expert Systems For Microwave Wireless Power Transmission Failure Prevention, Cameron Kerbaugh, Allen Mcdermott, Jeremy Straub, Eunjin Kim

Jeremy Straub

Wireless power transfer (WPT) can be used to deliver space-generated power to ground stations through the use of microwave beams. WPT satellite power delivery systems have two major failure states: misdi-recting a beam and failing to send power to a station. This project has implemented an expert system to perform pattern recognition in an effort to prevent failures by analyzing the system state and predicting potential failures before they happen in support of space-based testing [1] and deployment [2].

Rocket Flight Path, Jamie L. Waters

Jamie L Waters

This project uses Newton’s Second Law of Motion, Euler’s method, basic physics, and basic calculus to model the flight path of a rocket. From this project, one can find the height and velocity at any point from launch to the maximum altitude, apogee. Once complete this can be compared to what the actual values were to see if the method is a plausible way of estimation. The rocket used in this project is modeled after Bullistic-1 which was launched by the Society of Aeronautics and Rocketry at the University of South Florida.

A Control System For Space Solar Power, Jeremy Straub

Jeremy Straub

This poster presents an algorithm for the implementation of a control system that accepts power requests and makes distribution assignments to maximize the performance of the overall space solar power (SSP) system and meet service level agreements (SLAs). This complex process involves projecting service-customer demand into the future, projecting power availability on each servicing spacecraft and implementing corrective measures should actual craft performance not meet with planning expectations. The control system is implemented as a planning problem with some deterministic elements (craft position and generation) and some probabilistically predicted elements (interference, drag and malfunctions). A heuristic solver is proposed that …

Open Beyond Orbit: Using The Designs From The Open Prototype For Educational Nanosats Outside Of Earth Orbit, Jeremy Straub

Jeremy Straub

This paper presents an overview of the Open Prototype for Educational NanoSats (OPEN) and its prospective use in interplanetary missions. OPEN is framework to facilitate the low-cost creation of CubeSat-class spacecraft via using publically available (provided by the OPEN project) de- signs, software, fabrication instructions and test plans. The base open configuration is designed to be able to be produced with a parts budget of under $5,000. Despite this low cost, it is a very ro- bust spacecraft (with capabilities meeting or exceeding many of the vendor-kit solutions which cost eight-or-more times this amount).

Two approaches for using the OPEN …

A 6-U Commercial Constellation For Space Solar Power Supply To Other Spacecraft, Corey Bergsrud, Jeremy Straub

Jeremy Straub

This poster presents early stage planning for a constellation

of 6-U CubeSats which will collect power from

the sun and supply it to other spacecraft in Earth orbit. Unlike

solar panels (which have a known decay rate), antenna

systems (such as would be required to receive microwavetransmitted

power) do not substantially decay over the

typical (or prospectively extended, under this model)

spacecraft lifetime. This allows a spacecraft to be built for

long-term operations (utilizing an electric propulsion technology

and/or a greater supply of conventional propellant)

and receive power from a lower-cost utility provider

spacecraft, which can be replaced on a …

Small Satellites With Micro-Propulsion For Communications With The Lunar South Pole Aitkens Basin, Samudra E. Haque, Jeremy Straub, David Whalen

Jeremy Straub

A lunar sample return mission to the Lunar South-Pole Aitkens Basin (LSPAB) has been highlighted as a high priority objective of the most recent (2011) Decadal Survey for Planetary Science, by the National Research Council. This class of mission, however, faces a dramatic communications limitation, due to the lack of a frequent, or continuous, line-of-sight communications path to Earthbased ground stations. Brunner and others have proposed a communications system utilizing Low Lunar Polar Orbits (LLPO) and Lunar Halo orbits for this purpose. Ely and others have outlined proposals for using several communication satellites to form a relay network using LLPO, …

Numerical Prediction Of Exhaust Fan-Tone Noise From High-Bypass Aircraft Engines, Anupam Sharma, Simon K. Richards, Trevor H. Wood, Chingwei Shieh

Anupam Sharma

The ability to accurately predict fan noise is important in designing and optimizing high-bypass aircraft engines for low noise emissions. In this paper, a prediction methodology for exhaust fan-tone noise analysis is described and validated against various canonical test cases and NASA Source Diagnostic Test data (Heidelberg, L. J., "Fan Noise Source Diagnostic Test-Tone Modal Structure Results," NASA TM-2002-211594, 2002.). The prediction process consists of solving Reynolds-averaged Navier-Stokes equations to compute the fan wake and calculating the acoustic response of the outlet guide vanes to the fan wake using linearized Euler equations. Very good agreement is observed between the numerical …
