§ Mr. PERKINSasked the Under-Secretary of State for Air whether the Air Ministry has made any experiments with Diesel engines during the last year; and whether any trials have taken place and with what results?
§ Sir P. SASSOONExperiments with several types of engines embodying Diesel principles have been carried out 1143W during the past year and considerable progress has been made. A full type test for airworthiness has been satisfactorily completed with one such engine, which was developed from a standard Rolls Royce Condor petrol engine at the Royal Aircraft Establishment, Farnborough, and night tests are about to take place.
