16 February 2023, Royal Air Force Club, Piccadilly, London: Two former students in helicopters flight were awarded national achievement prize by the UK Vertical Flight Society for contributions to the field of rotorcraft.
30 January 2023. Lecture Notes on Rotorcraft Engineering published by Springer-Nature. Edited the book and contributed 3 Chapters (flight performance, gas turbine engine performance, rotorcraft conceptual design). The book is found on Springer-Nature and on Amazon.
28 November 2022. Received Silver Award for Best Paper at the Royal Aeronautical Society of London, Hamilton Place. The paper deals with environmental emissions calculations using ADS-B and Mode-S data. The numerical models explained in this paper have been implemented in our FLIGHT-X computer code.
The paper itself is found at DOI: 10.1017/aer.2021.2 A personal copy is provided on request.

25 November 2022: Published full review of technological development of contra-rotating propellers and open rotors. We examine the design drivers, propulsion gains, overall advantages and drawbacks of about 70 different aircraft, listed here. Paper available from the Aeronautical Journal.
21 October 2022: Signed contract with the AIAA for provision of training course on Aircraft Noise
With the new arrangements, a spring training course will be held on behalf of the American Institute of Aeronautics and Astronautics (AIAA). Full details at this link.
We continue to run an autum course, on a slightly different plan and contents, as described in our CPD page.

6 October 2022: Vertical Flight Society, UK Chapter: given webinar on contra-rotating propellers
With a historical perspective of the contra-rotating propeller (CRP), we provided context in the historical development of this fascinating propulsion system, from the fixed-pitch arrangements of the 1930s to the current advanced open rotors.
