Problems in Engine Research: Possible Developments Suggested by Recent Experience and Progress

THE aim of aviation engine research is to produce engines of higher power‐weight ratio, and of lower specific fuel consumption. To enable the full benefit of the power to be obtained when the engine is installed in an aeroplane, the shape of the engine must permit of a well streamlined cowling, and the means of cooling must provide the required heat dissipation with a low attendant drag. Finally, the running time between overhauls must be kept in view, and there must be good reliability, and good facilities for inspection and maintenance.
