A Practical Approach to Flight Dynamics and Control of Aircraft, Missiles, and Hypersonic Vehicles


Flight Dynamics and Control - Hypersonic Vehicles















Instructed by Bong Wie, Professor of Aerospace Engineering at Iowa State University

  • This course introduces a practical approach to flight dynamics and control of aircraft, missiles, and hypersonic vehicles, which utilizes MATLAB’s computational tools of control systems design and simulation
  • It will also cover a variety of flight control design examples to enhance the learning experience. They include Boeing 737 Max aircraft’s MCAS (Maneuvering Characteristics Augmentation System); SAS (Stability Augmentation Systems); ILS (Instrument Landing Systems); skid-to-turn, bank-to-turn, and coordinated turn of flight vehicles
  • All students will receive an AIAA Certificate of Completion at the end of the course


OVERVIEW

This course is intended for GNC engineers/researchers, flight control systems engineers, and graduate students, who are interested in a comprehensive overview of the fundamentals of flight dynamic modeling, analysis and control design of conventional aircraft/missiles as well as hypersonic vehicles. The lecture notes are in part based on numerous classical and modern textbooks on flight dynamics, guidance, and control published during the past 70 years.

However, this course employs a modern practical approach to flight dynamics and control of aircraft and missiles, which utilizes MATLAB’s computational tools of control systems analysis, design, and simulation. Consequently, some traditional/classical flight dynamic characterization methodologies of utilizing transfer functions, root-locus plots, and Bode plots, which have been treated in detail in most textbooks on flight dynamics and control, are not elaborated in this course by exploiting a modern practical approach to flight dynamics and control. Furthermore, recent advances in flight control systems design for conventional aircraft/missiles as well as hypersonic vehicles will also be emphasized.

WHAT YOU WILL LEARN

  • The basic physical concepts and mathematical tools required for the flight dynamic modeling, analysis, design, and simulation of aircraft and missiles

  • Modern state-space control design tools
  • Practical FCS examples of aircraft and missiles, including Boeing 737 Max aircraft’s MCAS.
  • High-AOA flight dynamics; LCDP; velocity vector roll; nonlinear dynamic inversion; Herbst maneuver
  • Flight dynamic modeling, guidance, and control of hypersonic vehicles

Instructors
Bong Wie is Professor of Aerospace Engineering at Iowa State University. He holds a B.S. in aerospace engineering from Seoul National University and a M.S. and Ph.D. in aeronautics and astronautics from Stanford University. In 2006 he received AIAA’s Mechanics and Control of Flight Award for his innovative research on advanced control of complex spacecraft such as solar sails, large flexible structures, and agile imaging satellites equipped with control moment gyros. He is the author of two AIAA textbooks: “Space Vehicle Dynamics and Control(2nd edition, 2008)” and “Space Vehicle Guidance, Control, and Astrodynamics (2015).” He has published 210 technical papers including 80 journal articles. He has three US patents on singularity-avoidance steering logic of control moment gyros. In early 2010s, he was actively involved in guidance, control, and astrodynamics research for deflecting or disrupting hazardous near-Earth objects (NEO). From 2011-2014, he was a NIAC (NASA Advanced Innovative Concepts) Fellow for developing an innovative solution to NASA’s NEO impact threat mitigation grand challenge and its flight validation mission design. His NIAC study effort has resulted in two distinct concepts for effectively disrupting hazardous asteroids with short warning time, called a hypervelocity asteroid intercept vehicle (HAIV) and a multiple kinetic-energy impactor vehicle (MKIV). During late 2010s, his research focused on further developing the ZEM/ZEV feedback guidance strategies for robotic/human Mars precision powered descent & landing with hazard avoidance and retargeting. He is currently exploring technically challenging, guidance and control problems of hypersonic reentry vehicles and an advanced guidance problem of missiles with precision impact time and angle control (ITAC) requirements. He is co-Editor of Astrodynamics, an international journal established in 2018. The following on-demand, online short courses by Dr. Wie are available from AIAA:
