David G. Mitchell, Mitchell Aerospace Research
Dave founded Mitchell Aerospace Research in March 2011
In his professional career of nearly forty years, Mr. Mitchell has been a contributor to the development of flying and handling qualities requirements for every type of air vehicle. He is a co-author of the report that became the Air Force’s Military Standard for Flying Qualities of Piloted Aircraft (MIL-STD-1797A), of the Army’s Military Standard for Rotorcraft Flying Qualities (ADS-33E-PRF), and of a proposed revision for the V/STOL Flying Qualities specification (MIL-F-83300).
Bachelor of Science in Engineering, University of California, Los Angeles, 1977
of Science in Aerospace Engineering,
February 2011 – Present: Mitchell Aerospace Research. Mr. Mitchell is an academic instructor in the Flying Qualities Phase at the USAF Test Pilot School, Edwards AFB, California. Currently, TPS students go through an 11-month program, with four months dedicated to the FQ Phase. This Phase is constantly undergoing modernization, with the introduction of advanced flight control methods, new analytical capabilities, and applications for Unmanned Aerial Vehicles (UAVs).
He is a Subject Matter Expert for the US Navy for handling qualities and flight control systems evaluations of the V-22 and CH-53K aircraft.
Mr. Mitchell is working with Systems Technology, Inc., to develop flying qualities requirements for UAVs, and new head-up display (HUD) guidance for US Navy F-18s.
December 2012 – Present: International Test Pilot School Canada (http://www.itpscanada.com/). Mr. Mitchell is on the academic staff at ITPS, teaching advanced flight control systems and handling qualities.
September 1993 – February 2011: Technical Director, Hoh Aeronautics, Inc. Mr. Mitchell was the Principal Investigator for a Phase II.5 SBIR with NAVAIR to develop an application package for ADS-33E-PRF. ASAP, the ADS-33 Specification Application Package, assists the user in determining the necessary data and processing the data for the application of ADS-33E-PRF. A significant portion of the SBIR effort has been dedicated to development of handling qualities requirements for maritime and cargo rotorcraft.
In addition, Mr. Mitchell was the Principal Investigator on a Phase III SBIR from NASA Dryden Flight Research Center to apply a PIO detection method to impaired aircraft. This research program included flight research performed by students and staff at the Air Force Test Pilot School, requiring Mr. Mitchell’s active participation in all aspects of planning, conduct, and analysis. He was Principal Investigator on a NASA Research Announcement sponsored by Ames Research Center to define acceptable levels of time-varying high-order dynamics in rotorcraft.
Since 1999, Mr. Mitchell has been actively supporting NAVAIR on flying qualities and flight control development for the V-22 Osprey tilt-rotor aircraft. He has participated in numerous simulations and flight test programs to investigate susceptibility to pilot-induced oscillations, to expand the Osprey’s flight envelope, and to determine the flying qualities of the aircraft following flight control system failures. In 2002 he presented a four-day short course on “Highly Augmented Airplane Flying Qualities” at the Naval Air Station Patuxent River, Maryland. Since 2007 Mr. Mitchell has also been supporting NAVAIR’s acquisition process for the new Sikorsky CH-53K helicopter, reviewing the flight controls and flying qualities portions of the acquisition.
Mr. Mitchell has developed pilot-induced oscillation (PIO) criteria and handling qualities demonstration maneuvers for the Air Force and NASA. A report for the U.S. Air Force, Development of Methods and Devices to Predict and Prevent Pilot-Induced Oscillations, is considered by engineers of the Federal Aviation Administration to be a “must-read” on the subject. He has also contributed to the development of flight director laws for a head-up display for a private company, and criteria for rotorcraft handling qualities under Army sponsorship. Through a series of contracts from Boeing Phantom Works, he has made technical contributions to the definition of handling qualities requirements for the NASA-sponsored High Speed Research aircraft. He has also assisted in the analysis of research data from flight and ground simulation studies of the flying qualities of large subsonic transports. He has been a contributor to numerous technical management programs conducted by the US Air Force Test Pilot School, including HAVE CAP, HAVE LIMITS, HAVE GAS II, HAVE RECKON, HAVE OLOP, HAVE ROVER, and Project Icarus.
1987 – 2008: Lecturer,
April 1977 – September 1993: Principal Specialist, Systems Technology, Inc. Mr. Mitchell was Project Engineer on Government-sponsored contracts to support research and development of military flying qualities requirements for helicopters and fixed-wing airplanes, and on a contract with a major airframe manufacturer to evaluate the susceptibility of a modern military transport to pilot-induced oscillations. Other assignments included duties as Project Engineer on a NASA-sponsored evaluation of the impact of cockpit feel system characteristics on flying qualities and pilot dynamics; on an Air Force study investigating the effects of simultaneous degradations of aircraft handling qualities in multiple axes; and on a NASA project defining the requirements for a task-tailored flight control system for the approach and landing of advanced transport aircraft.
July 1973 – April 1976: Engineering Trainee, Co-Op Work-Study Program, NASA Dryden Flight Research Center. During his undergraduate years, Mr. Mitchell was employed six months per year by NASA Flight Research Center (later Hugh L. Dryden Flight Research Center) in a work-study program.
