Historical Development of the Coaxial Contra-Rotating Propeller
The contra-rotating propeller (CRP) is one of the most fascinating propulsion systems in aviation. In one form or another it has been around for over 100 years.…

Samaras, or better known as “helicopter seeds”, are common childhood memories of many people. Behind the simplicity of a planar wing and a seed, is a complex mystery of flight mechanics.
At present, uncrewed aircraft (UA) are widely used around the world, in fields including aerial photography, express transportation, emergency rescue, electric power inspection, agricultural plant protection, border monitoring, mapping, fire monitoring and environmental protection.
The work described in this paper is part of the outcome of the MIDAS project, funded by the Natural Sciences and Engineering Research Council (NSERC) of Canada, which intends to optimise novel transport aircraft configurations where drag reduction is assumed as resultant of High Aspect Ratio Wings (HARW).
Remote sensing allows mapping of climate, vegetation and terrain features over large regions on the ground while repeating taking images consistently over years.…
Guided missiles are critical weapon systems with high precision and destructive power. They have been used since World War II, and with scientific and technological improvements, they have become a major part of military aviation.…
This online collection commemorates 75 years of aerospace engineering teaching and research at the University of Bristol. However, interactions with the aircraft industry started long before the Department was formed in 1946 1, for instance when in 1918 the University began teaching a class in Aircraft Manufacturing .
ISABE started 50 years ago when the ICAS (International Council of Aeronautical Sciences) community identified the need for a bespoke propulsion forum and conference.
More than 99% of air molecules on Earth exist below 50km altitude and therefore, there is certainly an upper limit on altitude for an aircraft to reach, while there is a lower limit on an orbit for a spacecraft to operate, as even a low density of air causes large drag due to the high orbit velocity with an unfavourable effect on its operation duration.
The tactical systems and operational environment of modern fighter aircraft are becoming increasingly complex.
The first edition of The Aeronautical Journal predates the first human powered flight by the Wright brothers by some five years. Even back then it knew that there was to be a rich future for man in flight to come.
Beyond the dark clouds there is light. Is this a topical description for the past, present and future of our industry? In the past, it was our ambition to travel fast and above the weather that inspired the development of the jet engine by its inventors, Sir Frank Whittle and Dr Hans von Ohain in the late 1930s and early 1940s.
The Aeronautical Journal is unusual in ‘covering all aspects of aerospace’. This is something of a rarity nowadays, with conferences and journals aiming to attract high-profile experts by maximising specialist content – more ‘bang for the buck’, as the expression goes.…
It is an enormous honour for me to take over from Professor Peter Bearman as Editor-in-Chief of the world’s oldest aeronautics journal.…
Technology challenges of stealth unmanned combat aerial vehicles by Eduardo Sepulveda & Howard Smith provides a summary of the technical and operational design challenges specific to UCAVs, focusing on high-performance, and stealth designs.…
The paper, ‘Numerical investigation of the fatal 1985 Manchester Airport B737 fire’ published in the Aeronautical Journal, Vol 121, Number 1237, pp 287-319, 2017 by Edwin R Galea, Zhaozhi Wang, and Fuchen Jia, provides an explanation for why 55 people lost their lives in the B737 fire at Manchester airport in 1985.…
This blog post is taken from the Foreword to the special edition of The Aeronautical Journal published to celebrate the 150th Anniversary of the Royal Aeronautical Society.…
