RAeS Bristol Branch presents….
A Christmas Lecture
Engineering Magic
Professor Jon Holt, Scarecrow Consulting

Join engineer and award winning author Professor Jon Holt, AKA the ‘Engineer in the Hat,’ for a magical evening of Science, Technology, Engineering and Mathematics.
In this family lecture, he will explore the power of numbers; the impact that they have on our everyday lives; and why they are so important for STEM. Learn how we can use numbers to predict the future, read minds and influence our lives. Explore how we can also use numbers for the greater good and the not-so-greater good!
Expect an evening of wonder with plenty of audience participation, terrible jokes, a bed-time story and some mind-blowing magic.
This exciting and interactive lecture is the perfect mix of educational and fun and will interest and inspire adults and children alike, so please bring the family along!

En-route to the all-electric aircraft 
Design of a hybrid powertrain for an electric helicopter tail rotor

by Dr Jason Yon and Prof. Phil Mellor
University of Bristol
Collar RAeS Named Lecture
Over the past decade, continued advances in electric machines, energy storage and power converter technologies have made electric propulsion for aerospace a realistic proposition, with several research projects and demonstrators currently under development.

In collaboration with industrial partners, the University of Bristol has developed a novel hybrid aerospace powertrain for an electric helicopter tail rotor. The system uses a high-performance fault-tolerant machine to drive the tail rotor and a set of four high-speed generators to source the electrical power. This architecture allowed a high efficiency and low weight solution to be achieved while meeting the crucial application integrity requirements.

The presentation will offer an overview of the electromechanical design of this system and its key performance attributes. As a case study, this project provides a valuable platform to explore several challenges facing the industry as it moves towards all-electric propulsion.

6.30pm – Thursday 29th November 2018 (refreshments from 6pm)
