§ 43. Mr. Garro Jonesasked the Chancellor of the Duchy of Lancaster whether any research under Government auspices is proceeding into the development of the Diesel aircraft engines; and whether, having regard to the amount of fuel saving, authoritatively estimated at about £500 per 4,000 cruising horse-power for 24 hours and other advantages, he can make any report of progress?
§ The Chancellor of the Duchy of Lancaster (Earl Winterton)Research on compression ignition aero-engines has been in active and continuous progress for many years under Government auspices. Complete engines of British design were successfully tested on the bench and in the air several years ago, but showed a marked disparity in performance compared with petrol engines. Recent progress has been encouraging in offering some reduction in this disparity, but the work has not yet reached a stage at which a report can usefully be made. The reduction in fuel cost and other advantages offered by the use of heavy oil engines are fully appreciated, but they cannot in themselves be accepted without substantial qualification as an indication of the practical benefit to be obtained.
§ 44. Mr. Garro Jonesasked the Chancellor of the Duchy of Lancaster whether he will arrange for a translation of the 1,000 page German volume entitled "Jahrbuch 1937 Der Deutschen Luftfahrtforschung," which contains a vast amount of information upon modern aeronautical research, for the information of members of the Aeronautical Research Committee and others?
§ Earl WintertonI do not think that a translation of the entire contents of the volume referred to is called for. Full translations of some portions and abstracts of others have been made and circulated to the members of the Aeronautical Research Committee and to staffs of research establishments.
