Measuring engineering quality in airplane development
… quality metrics to the multiple stages of the airplane development process at Boeing Commercial Airplanes. This project first identified integration and process discipline as most critical towards final quality of the engineering work. Integration, defined as the path and connectivity between …

Airplane trajectory expansion for dynamics inversion
In aircraft research, there is keen interest in the procedure of determining the set of controls required to perform a maneuver from a definition of the trajectory. This is called the inverse problem. It has been proposed that if a complete set of states and state time derivatives can be derived …

Assessment of airplane design, fabrication, and repair
… process. This paper discusses all stages of airplane design, fabrication, and repair, and attempts to provide a comprehensive view of the overall procedure instead of just one aspect. In most cases, the Boeing 747 is used as an example, though most commercial aircrafts are built in a similar …

Nonlinear control of an aerobatic RC airplane
… of backstepping is applied to an aerobatic RC airplane. The controller asymptotically tracks a time-parameterized position reference, and depends on an orientation look-up rule to determine the vehicle orientation from a desired acceleration. A coordinated-flight look-up rule compatible with …

Singular trajectories in airplane cruise-dash optimization
The problem of determining cruise-dash trajectories is examined for the case of time-fuel optimization using a linear combination of time and fuel as the performance index. These trajectories consist of a transient arc followed by a steady-state arc. For cases where the steady-state arc is flown …

Designing and implementation a new supply chain paradigm for airplane development
The 787 program is the latest airplane development program in Boeing Commercial Airplanes. In this program, many new business processes, including a new supply chain structure will be implemented. Based on my six-month internship in Boeing, this thesis will address two critical supply chain issues …

The Propulsive Design Aspects on the World’s First Direct Drive Hybrid Airplane
<p>The purpose of this thesis is to design a safe technology demonstrator by implementing a direct drive propulsion system for a gas-electric hybrid aircraft. This system was integrated on the Embry-Riddle Eco-Eagle for the Green Flight Challenge 2011. The aim of the system is to allow the pilot to …

Analysis of customer-driven and systemic variation in the airplane assembly process
… costs of the manufacturing and assembly of an airplane. Due to the complexity of the product it has been exceedingly difficult to determine whether the process is inherently unstable or if there are unique characteristics of individual planes that drive the differences in cost. This paper …
