Next Sponsored Lecture

This programme has been in recess since 2002 when the following was planned.

The development of the gas turbine engine in the 21st century
Speaker to be confirmed


The gas turbine engine is a mature and reliable powerplant. It is a fundamental part of the aviation industry, and will continue to be essential for the ongoing operation of civil and military aircraft for the foreseeable future. The developments that have occurred during the first 60 years of the technology have been substantial, and further development of the technology is anticipated in the 21st century.

The theme of the lecture will be a technical presentation on the future technologies that are possible - what we might be able to do in the future rather than what we can do now.

The factors impacting the future development of gas turbine engines will be addressed. As well as developments to improve power and efficiency, other considerations are likely to become increasingly significant. These include the environmental impacts of gas turbine engines, emission and noise standards, and potential limits to the development of the technology.

The lecture will include:

  • A brief history of the development of the gas turbine engine to date.
  • A survey of the current state of the art, particularly in terms of the emissions and noise performance
  • Brief summary of the performance and capabilities of the current generation of gas turbine engines.
  • Overview of the state of the atmosphere, the impact aviation has had to date and the possible future impact of aircraft operations.
  • Aspects of engine development that are currently being planned and developed.
  • Possible development opportunities that are theoretically possible but beyond the capability of current technology.
  • Limits to the development of gas turbine engines.


This lecture was originally scheduled for October 2001, but was delayed as a consequence of the September 11 terrorist attacks in the USA. It was rescheduled to March 2002, but that has since had to be delayed again. It is hoped to stage this or another lecture in future.
