The Compression‐Ignition Engine: The Present Position of an Engine of the Future

AMONG the less well‐known activities of the Royal Aeronautical Society is the administration of a number of funds which endow prizes to encourage the production of technical papers on various subjects. One of the most important of these prizes is that initiated in commemoration of the early pioneer work in heavy‐oil engines of Herbert Akroyd Stuart. Regular readers of AIRCRAFT ENGINEERING may remember that in our issues of February and March, 1931, we published the paper by Mr. D. R. Pye, which was awarded the first Akroyd Stuart Prize.
