Insights into VTOL Aircraft Design

by Dr. Rafi Yoeli

The emergence of Urban Air Mobility (UAM) as the “next frontier” in aerospace innovation, has brought the aerospace industry and especially Vertical Takeoff and Landing (VTOL) aircraft into the center of public attention. Conquering this uncharted UAM airspace requires new standards and capabilities for VTOL which bring fresh and exciting challenges to today’s and tomorrow’s aerospace engineers. Successfully meeting those challenges requires a solid foundation in the essential principles of VTOL aircraft design. In this lecture which is the first of a series of planned lectures on VTOL aircraft design, Dr. Rafi Yoeli will present his own perspective on the theoretical foundations of VTOL flight, design options for sustainable power in future VTOL aircraft, and an overview of the unique aerodynamics of VTOL flight.  The lecture will also include references to safety and certification standards.

Dr. Yoeli’s career spans decades of aeronautical experience in all aspects of aircraft design and development. For most of the last 20 years, Dr. Yoeli’s work has been devoted to VTOL aerodynamics and configuration design. In the last few years Dr. Yoeli has been deeply involved in the emerging Urban Air Mobility market. One of his designs is the passenger carrying CityHawk with the aim of creating a VTOL aircraft with true “fly anywhere, land anywhere” capability.

It features 100% sustainability, relying on emerging Fuel Cell hydrogen powertrain technologies. Dr. Yoeli has registered 32 patents and patent publications in his name, most in the field of ducted fan aerodynamics. He is also a licensed pilot for both fixed-wing and rotary-wing aircraft.

There is no charge for the Lecture, but attendees are requested to pre-register by May 19th, 2021 here

Perspectives on (Aerodynamic) Drag

Perspectives on (Aerodynamic) Drag

by Dr. John Maris FRAeS, FCASI

Aerodynamic drag is the nemesis of the aircraft designer, but its causes and effects are often misunderstood. In this lecture, Dr. John Maris, FRAeS, FCASI, will present an amusing retrospective on drag, its causes, and mitigation. Key points will be accentuated with historical imagery and video clips. Along the way, Dr. Maris will answer some commonly asked questions (what would happen if golf balls weren’t dimpled? Why does the 747 have a hump?). He will also try to dispel some longstanding myths (no, it’s not air friction that causes re-entering space vehicles and meteorites to glow red-hot). Along the way, Dr. Maris will highlight a simple error that held back aircraft design for more than twenty years. Please join us for an interesting journey beginning in 1738 when Daniel Bernoulli published his Hydrodynamica, and ending with Virgin Galactic’s SpaceShipOne deploying its “feathers” during re-entry.

Dr. Maris is the Chairman of the Montreal Branch of the Royal Aeronautical Society. He is an Aviation Week and Space Technology Laureate and a Canadian Aviation Hall of Fame inductee. Dr. Maris is an Associate Fellow of the Society of Experimental Test Pilots and has a Ph.D. in Aviation Safety and Human Factors. He is a practicing aeronautical engineer, lecturer, and experimental test pilot.
