This multi-rotor aircraft system was developed to transport blood products up to 10 miles while maintaining cargo temperature. I collected performance requirements, identified a suitable aircraft, and modified it to accept a medical payload. Modifications included upgrade of radio links, integration of professional-grade power systems, and design of a carbon fiber frame with integrated cargo mounting and landing gear.
In partnership with Johns Hopkins, I validated the aircraft’s performance by flying samples of red blood cells, plasma, and platelets. The publication of this work is in prep.
We are currently working with the FAA and certified testing sites to create a test plan culminating in FAA certification.
The Medical Cargo Drone is a fixed-wing aircraft system developed to transport medical cargos and be operated by non-technical personnel. I collected information about customer needs in the field, distilled aircraft performance requirements, and worked with a manufacturing partner to create a custom aircraft design suited to this application. We are currently validating performance of the prototypes.
I developed this aircraft for a study of the effects of drone flight on microorganisms. I interfaced with medical personnel to distill the aircraft and specimen requirements, selected a suitable airframe, and designed modifications to make it compatible with the cargo and autonomous operation from small unprepared fields.
Flights with live specimens were performed in partnership with Johns Hopkins using human blood and sputum seeded with a variety of microorganisms. This work was submitted for publication in March 2016.
Fixed-wing drones require airport-style landing fields, which are often unavailable near medical facilities. For most low-cost drones, landing space requirements are not published. I characterized the landing requirements of an aircraft appropriate for use in a low-cost medical courier system. I modified the aircraft and developed flight profiles that reduce the landing space requirements.
I developed this aircraft for a study of the effects of drone flight on human blood chemistry samples. I interfaced with medical personnel to distill the aircraft and cargo requirements, selected a suitable airframe, and designed modifications to make it suitable for the medical cargo. This included iterative design, crash testing, compliance with IATA medical transport laws, and performance evaluation flights.
The flights with live samples were performed in partnership with Johns Hopkins. We used blood taken from human subjects, and found that the drone flight had no negative impact on the specimens. This work was published by PLOS One in July 2015.
The Cuttlefish is a robotic submarine that moves through the water with biomimetic fins. The third-generation vehicle was built to ruggedize the propulsion system and improve endurance. I designed, assembled, and tested all aspects of the vehicle.
The Mk63 Wingkit is an assembly added to the Mk63 naval mine that extends its gliding range and provides precision guidance. I designed the wing folding mechanism and actuation system.
The Gulfstream G650 Empennage Flutter Model is an actuated aeroelastic flutter wind tunnel model. I designed remote model positioning systems, synchronized model excitation systems, and associated control software. I supported these systems through several rounds of validation testing and wind-on data collection in NASA Langley's Transonic Dynamics Tunnel.
The Ranger One wind tunnel model was ordered by Boeing to perform experiments with active damping of aeroelastic flutter in NASA Langley's Transonic Dynamics Tunnel. I built an Arduino-based system to validate the sensors, actuators, and control software.
Many small-to-medium drone engines are supplied without accurate performance data. I designed a dynamometer test system for the 3W 684i engine, collected dynamometer test data, and measured fuel consumption.
The Cuttlefish is a robotic submarine that moves through the water with biomimetic fins. The second-generation vehicle was built to improve efficiency and speed. I designed, assembled, and tested all aspects of the vehicle.
The Radiation Hardening Technology for Ascent Intercept Avionics is a module that detects nuclear events, and protects connected avionics electronics. I created a demonstrator, produced a demo video, and performed a live demo for the US Missile Defense Agency.
The Cuttlefish is a robotic submarine that moves through the water with biomimetic fins. The first-generation vehicle was built to explore bio-mimetic fin movement strategies. I designed, assembled, and tested all aspects of the vehicle.
SAE Mini-Baja is a student design and racing competition in which teams build off-road racing buggies. I revitalized the University of Portland’s dormant program, and we built two cars. The first was an adaptation of an existing frame. The second was a clean-sheet design. I focused on the suspension system, including development of kinematic models, optimization, fabrication, and testing.
Formula SAE is a student design and racing competition in which teams build an open wheel race car around a 600cc motorcycle engine. I founded the University of Portland’s team. As lead engineer, I oversaw technical direction of all car systems. My technical focus was the drivetrain design and engine tuning.
