Modeling And Test Of The Efficiency Of Electronic Speed Controllers For Brushless Dc Motors, Clayton R. Green

Master's Theses

Small electric uninhabited aerial vehicles (UAV) represent a rapidly expanding market requiring optimization in both efficiency and weight; efficiency is critical during cruise or loiter where the vehicle operates at part power for up to 99% of the mission time. Of the four components (battery, motor, propeller, and electronic speed controller (ESC)) of the electric propulsion system used in small UAVs, the ESC has no accepted performance model and almost no published performance data. To collect performance data, instrumentation was developed to measure electrical power in and out of the ESC using the two wattmeter method and current sense resistors; …

Designing A Remote Aerial System To Image And Analyze The Health Of Grape Crops At Cal Poly San Luis Obispo, Alexander D. Vice, Dylan Benton, Adipratnia Asmady, Andrew Mercier, Andrew Meyer, Eric Belfield, Aaron Drake

STAR Program Research Presentations

In the last decade the prevalence of unmanned aerial vehicles (UAVs) has exploded; however, the presence of UAVs in research situations is still a relatively new and untested field. The autonomous flight lab (AFL) at Cal Poly San Luis Obispo is a new lab site that is dedicated to using UAVs to benefit research for all backgrounds. Before AFL was able to fly missions we first needed to actually receive our vehicles, create a lab space that would provide all of the necessary resources and equipment necessary to fly, and to be granted permission by the Federal Aviation Administration (FAA) …

The Robert & Esther Goddard Papers, Robert H. Goddard

Finding Aids

Dr. Robert H. Goddard was a member of the Clark Physics Department for 29 years. Foremost American pioneer of rocket research, he laid the technical and theoretical foundations for many of the developments in long-range rockets, missiles, satellites and space flight, which collectively put us into the Space Age.

The collection includes correspondence, diaries, journals, patent applications and awards, reports, and photographs. The collection also includes original paintings by Dr. Goddard.

How To Save The World: One Life (And Uav) At A Time!, Natalie A. Wright

STAR Program Research Presentations

The proliferation of Uninhabited Aerial Vehicles (UAV’s) in commercial and public service aviation arenas has begun to gain the attention of many citizens. Popularized vehicles such as quadcopters have applications in aerial photography, small package delivery and hobbyist/consumer interests. Use of small-scale, fixed- and rotary-wing, remotely operated systems has been popularized as a result of such vehicles’ size and operational simplicity, which widens the range of application of this technology. Public service applications have the potential to advance emergency services management, which can substantially contribute to the public wellbeing. This research will examine the utility of multi-rotor systems in the …

An Overview Of A Solar Eclipse Video Payload, Alexander M. Peters

2017 Academic High Altitude Conference

The HABET group at Iowa State University has been designing and building balloon payloads for years, giving students hands on experience with the engineering involved in creating and launching payloads to near space conditions. After attending the AHAC conference in 2014 the group begain to design a balloon for the 2017 solar eclipse. Working closely with the Space Grant Consortium’s design team, HABET has designed and completed preliminary testing on a Solar Eclipse Video payload. This payload uses multiple subsystems to complete the mission. The mission required an altitude control system, live video downlink, and a camera pointing system. Our …

Techniques For Payload Stabilization For Improved Photography During Stratospheric Balloon Flights, James Flaten, Christopher Gosch, Joseph (Benjamin) Habeck

2017 Academic High Altitude Conference

Payload-box rotation and swing are perennial challenges to achieving high-quality photography (typically videography) during weather-balloon flights to “near-space” (AKA the stratosphere). Continuous camera motion can lead to blurred still photos, nearly-impossible-to-watch video footage, and precludes time-exposure photography required for most astronomical imaging even though altitudes are reached where the daytime sky appears black. Apparently-random payload rotation, persisting even at altitude, can often exceed servo rotation rates and frustrate attempts to do active camera pointing. Here we discuss mostly-passive payload stabilization strategies we, and our collaborators, have used to mitigate and dampen both swing and rotation of suspended payloads on high-altitude …
