Flight Management and Data Acquisition System for a Dynamically Scaled Model Airplane

Quest® Aircraft Company, LLC is beginning a project to use dynamically scaled radio controlled aircraft models to reduce the risk in developing new full scale aircraft.

Background
Full sized test	airplanes are expensive	to build. As engineering nears production, changes become increasingly difficult, if not impossible, to implement resulting in engineering "bandaids" such as vortex generators.

One potential solution is to create a dynamically scaled model that will behave similarly to the full-sized aircraft during flight. An onboard data acquisition system facilitates collection of various data parameters from the models during flight, the analysis of which will allow determination of the full-scale aircraft dynamic characteristics.

Control Surface Force Measurement

 * A factory-paired strain gauge and rigid metal strip will likely serve as part of the servo linkage. An HX711 load cell amplifier on a breakout board containing voltage conditioning and A/D conversion electronics relays a reading from the load cell to a microcontroller. The microcontroller then processes the data for real-time control and data acquisition by the Raspberry Pi.

Motor Torque and Thrust Measurement

 * Ways to incorporate strain gauges into a custom load cell and how that load cell will mount to the engine and firewall of the model are being considered. An engine test stand has been constructed to not only properly and safely break-in the engine, but to allow mounting of test fixtures to measure it's characteristics, or the characteristics of other components in the presence of the engine's air flow and vibration. By mounting the engine to a plate connected to a pair of linear pillow-blocks, a force gauge can be attached to the plate to measure the thrust produced.

Avionics and Data Aquisition

 * A Raspberry Pi computer paired with a NAVIO+ autopilot shield and running ArduPilot APM software forms the core of the flight-control system. The on-ground pilot's radio control is routed through this system, providing software assisted stabilization and emergency scenario autopilot.  A separate radio system relays flight data to a ground station running flight management software.

I am 23 studying Mechanical engineering at the University of Idaho. I grew up in Moscow as well as lived in Brazil for 2 years serving a full time proselytizing mission for the Church of Jesus Christ of Latter-day Saints. I am an active member of Engineers Without Borders (EWB) and I am serving my second year term as project lead. I have traveled to Bolivia as part of an EWB travel team to collect data required for future projects. I am fluent in Portuguese and have a working knowledge of Spanish. I have worked as an intern for Siemens in their Building automation division, and currently work as a research lab technician at WSU SSL Lab. I enjoy outdoor activities and frequently hike, rock climb, backpack and mountaineer. I am a marathon finisher and am training for my second.

I am excited to be involved in this project, I have been trying to figure out where I want to go with my degree and see this as a great opportunity to help me decide!

I am a senior in University of Idaho's Electrical Engineering program and currently interning for Schweitzer Engineering Labs' Engineering Services in automation. My field of interest is in system control and data acquisition with an emphasis on power, but really anything involving PLCs. I’m originally from Sandpoint, ID, and like to snowboard when I can make it up to Schweitzer Mountain.

I joined the army in 2001 at the age of seventeen as a junior in high school. After graduating, I spent 7 months in Georgia where they trained me in electronics maintenance. From mid-2004 to early 2006, I was deployed to Iraq the first time. Between 2006 and 2009, I was a UAV ground crewman and professional mechanic. In 2009, I enrolled in college and in 2011 was redeployed to Iraq for one year. After which, I continued my college career until now. In 2013 I retired from the Army.

In my free time, what little there is, I like to work on cars, electronics, and guns. During the summer, I spend my time reconstructing a house.

I am a lined up to graduate this May and eager to push my skills and test my knowledge on a true design project. The dynamically scaled model airplane is where I believe I can do this the best. My interest in Electrical Engineering started my senior year in high school physics. My teacher took us through an electrical section and I loved it. I switched my intended major to Electrical Engineering after this. Now, I can hardly believe I have the opportunity to join in on this exciting project.

I am an electrical engineer in the process of completing my senior year at the University of Idaho. On top of working with the electrical system, I am responsible for creating and maintaining the team’s budget as well as purchasing all the necessary items to complete our project. When I’m not working on school work or attending class I like to golf, hike and camp.
