| Title | Letter from [Dugald Clerk] to Commander Cecil Ryther Acklom, Superintendent, Royal Torpedo Factory, Greenock |
| Date | 22 December 1914 |
| Description | Reporting discussion at the Royal Society Engineering Committee meeting on torpedo propulsion. The use of ammonia would not lead to improvements. However, Clerk has calculated how the existing cold air torpedo engine might give better range results. For the large 21-inch torpedo, a new engine design would be required. An internal combustion engine would yield better results and Clerk offers to design one. |
