Assessment And Comparison Of Aviation Manufacturing Industries Throughout Mexico And Brazil, Omar E. Morsi, Kelly A. Whealan-George, Aaron D. Clevenger Aug 2018

Assessment And Comparison Of Aviation Manufacturing Industries Throughout Mexico And Brazil, Omar E. Morsi, Kelly A. Whealan-George, Aaron D. Clevenger

Aaron D. Clevenger

This literature review serves to provide insight and understanding in regards to the evolving aviation manufacturing industry throughout the globe and more specifically, Mexico and Brazil. Increased demand for aircraft units both in the commercial and private sectors have led to unprecedented expansions in aircraft manufacturing across the industry. In order to illuminate certain potentials and current growth levels of such industries, this review will delve into an array of information and specifications in regards to economic, political, and cultural influences throughout both Mexican and Brazilian markets respectively. In conclusion, the review will identify the transformation of an aviation manufacturing …

Validation And Verification Flight Tests Of Fixed-Wing Collaborative Uass With High Speeds And High Inertias, A Ram (Bella) Kim Jun 2018

Validation And Verification Flight Tests Of Fixed-Wing Collaborative Uass With High Speeds And High Inertias, A Ram (Bella) Kim

A Ram (Bella) Kim

The research objective for this work is to validate and verify guidance, navigation, and control algorithms that are designed for fixed-wing collaborative unmanned aerial systems (UASs) in unstructured environments. A biologically-inspired swarm control theory provides a framework to distribute sensor payloads between several smaller and less complex agents that have local interactions. Controller design and flight testing of large UASs with high speeds and high inertias holding a formation in a dynamically changing environment and in the presence of external disturbances is complex and requires advanced planning and safety measures. Verification and validation flight tests were conducted using a fixed-wing …

Control Of Multi-Agent Collaborative Fixed-Wing Uass In Unstructured Environment, A Ram (Bella) Kim Jun 2018

Control Of Multi-Agent Collaborative Fixed-Wing Uass In Unstructured Environment, A Ram (Bella) Kim

A Ram (Bella) Kim

Swarms of unmanned aircraft are the inevitable future of the aerospace industry. In recent years, swarming robots and aircraft have been a subject of much interest; however, many research projects make impractical assumptions such as point mass dynamics with no aerodynamic effects for aircraft models, and most works stop short of fully validating their methods via flight testing. This work presents a proximity based guidance, navigation, and control of multi-agent fixed-wing unmanned aerial systems in an unstructured environment. A scalable swarm navigation method is developed using adaptive moving mesh partial differential equations controlled by the free energy heat flow equation. …

Validation And Verification Of Gnc For Large Fixed-Wing Unmanned Aerial System In Unstructured And Noisy Environment, A Ram (Bella) Kim Jun 2018

Validation And Verification Of Gnc For Large Fixed-Wing Unmanned Aerial System In Unstructured And Noisy Environment, A Ram (Bella) Kim

The impact of high update rate on the disparity in eigenvalues of the auto-correlation matrix, along with slow convergence and reduced stability of numerical analysis are well studied. However, the impact of high update rates of autopilots on the performance of unmanned aircraft has been ignored due to the intrinsic limitations of COTS autopilots
computation power. Although MEMS based IMUs have very high update rates, the majority of existing UAS autopilot system processing power is limited to 20 Hz. In this work, the challenges and processes for developing and flight test validating an autonomous flight controller for a large 30-kg …

Space Operations In The Suborbital Space Flight Simulator And Mission Control Center: Lessons Learned With Xcor Lynx, Pedro Llanos, Christopher Nguyen, David Williams, Kim O. Chambers Ph.D., Erik Seedhouse, Robert Davidson May 2018

Space Operations In The Suborbital Space Flight Simulator And Mission Control Center: Lessons Learned With Xcor Lynx, Pedro Llanos, Christopher Nguyen, David Williams, Kim O. Chambers Ph.D., Erik Seedhouse, Robert Davidson

Pedro J. Llanos (www.AstronauticsLlanos.com)

This study was conducted to better understand the performance of the XCOR Lynx vehicle. Because the Lynx development was halted, the best knowledge of vehicle dynamics can only be found through simulator flights. X-Plane 10 was chosen for its robust applications and accurate portrayal of dynamics on a vehicle in flight. The Suborbital Space Flight Simulator (SSFS) and Mission Control Center (MCC) were brought to the Applied Aviation Sciences department in fall 2015 at Embry-Riddle Aeronautical University, Daytona Beach campus. This academic and research tool is a department asset capable of providing multiple fields of data about suborbital simulated flights. …
