Aircraft Design & Consulting

An understanding of the conceptual and preliminary design of aircraft is imperative for the success of any aeronautical engineer working for a prime contractor. Few engineers are directly involved in conceptual and preliminary design. Most work in other specialized technologies that provide contributions to the aircraft design and operation. Understanding the significance of their contribution, and the multi-disciplinary optimization that occurs in the design process whereby their contribution of technology is traded against other technologies, is critical to producing a well-rounded aerospace engineer. ABET accreditation requires a capstone course in aerospace vehicle design in order to achieve this goal.

Our Mission
The goal of ADAC is to provide instruction in aircraft conceptual and preliminary design so that the student understands:
ADAC will also provide consulting services in aircraft design and operations to industry and academia.
The Lockheed L-1011 and Douglas DC-10 were both designed to meet the American Airlines requirement for an ORD-LAX widebody. The commercial aircraft industry might be very different today if either company had looked beyond that requirement, considered the future growth in big high bypass ratio fan engines, and built a twin-engined aircraft instead.

Sometimes a successful design is a matter of being in the right place at the right time. The DHC-6 Twin Otter was designed as a floatplane, but with fixed landing gear it happened to meet the FAA commuter airplane definition of having a maximum takeoff gross weight under 12,500 lb and carried 19 passengers. It was sturdy and reliable with PT-6 engines, and was popular with commuter airlines. It has a maximum wing loading of only 30 lb/ft2 and the ride can be uncomfortable on a hot day. The type certificate has been purchased by Viking Air in Vancouver, BC. First flight of the Series 400 aircraft was on Feb 19, 2010.
Tony Hays has worked in the aircraft industry for over 50 years. He has worked for aircraft manufacturers in the United Kingdom, Canada and the U.S. He has taught classes in aircraft design in the U.S. and China. He has a B.Sc. degree in Aeronautical Engineering from Bristol University and an S.M. degree in Aero/Astro Engineering from MIT.  He currently teaches at California State University Long Beach in the Fall semester, and Nanjing University of Aeronautics and Astronautics in the Spring semester.
