Dr Raj Nangia, recently known for: Greener aviation via aircraft operations in Aviation, incorporating Air to Air Refuelling & Formation Flying & Alternative fuel Aircraft, will share the challenges and a potential solution for a LH2 powered commercial passenger aircraft.
Environmental considerations are focusing attention towards using LH2 for commercial aircraft. But LH2 has many engineering challenges to overcome over current aviation fuels. Aerodynamic design must be innovative, safe and certifiable. An LH2 fuel system must be segregated from the passengers – no obstruction of exits and compliant with emergency landing requirements. The airframe has to reasonably survive engine disc burst.
A “Gondola” concept offers an opportunity for a medium range (160-180 seat) LH2 design that will meet these challenges, featuring a twin-fuselage - one with passengers and the other with fuel tanks. This concept demonstrates clear crashworthiness, evacuation, fuel management, ground handling and other advantages.

Since joining the AAIB in 2010 Lisa has been involved in investigating accidents and serious incidents to a wide range of aircraft types including fixed and rotary wing commercial air transport aircraft, general aviation aircraft, gliders, hot air balloons and remotely piloted aircraft.
Lisa is a Chartered Engineer and a member of the RAeS, where she also sits on the Society’s Human Factors Engineering specialist sub group. Additionally, she is an accredited human factors specialist with the European Association of Aviation Psychologists and an associate member of the Chartered Institute of Ergonomics and Human Factors.
The engineering aspects of an air accident investigation aim to understand whether the aircraft or its systems played any part in the accident and whether the manner in which the aircraft was designed, tested, certified or maintained may have played a role. Underpinning all of that is the importance of understanding any human contributions. As investigators we need to look at the human interactions and organisational influences that may have contributed to an accident, whether in the immediate lead-up to an accident or further back in time. Drawing upon several recent examples, this presentation will explore some common themes relating to human performance and organisational factors which have emerged during technical investigations. And it will suggest how a more human-centred approach to aircraft design, specifically with maintainers in mind, might form part of the solution.

Beyond the Rotor: Exploring the world of Helicopter Operations
Helicopters hold a unique place in aviation, combining mobility and precision to perform missions no other aircraft can accomplish. This presentation, Beyond the Rotor: Exploring the World of Helicopter Operations, delves into the fascinating capabilities of helicopters, their challenges, and the inspiring stories that highlight their impact on industries and communities.

What control strategies can be effectively modelled in Simulink for attitude control of CubeSats, and how do these strategies perform in prototype tests?
This lecture investigates various control algorithms for attitude determination and control systems (ADCS). Attitude control is critical to CubeSat operations as it ensures precise orientation control, which is essential for communication, navigation and imaging. The project comprises two main components: a simulated model implemented in Simulink and MATLAB and a prototype designed for testing and validating the model.

Biplanes & UAV’s; the similar early days of manned & unmanned aerial warfare.
This lecture will look at the development of the roles of aircraft and UAVs over time from before the first World War to the current day. The equivalent jump for UAV development to World War One can be somewhat mirrored over the course of decades, not years. However, we can use the history of manned aircraft development to look at what might be in store for UAV’s.
