Hs.{Lord Ernest Hives - Chair} Lr.{Mr Ellor} E3/N.23.4.30. ---------------- Re: Installation of Phantom II Engine in a Mark I Light Tank. ---------------------------------------------------------------- Herewith please find drawings No.LEC.2795/6/7, showing proposed rough scheme for the above. We have brought this to the stage when we think it should now be discussed with the Technical Officers of the Tank Department, and it is proposed as per our conversation that you should get in touch with Col.Hudson for this purpose. The one uncertain feature about the scheme we consider is whether or not there will be sufficient cooling capacity for the full horse power of the engine and before any actual installation work were undertaken it would be necessary to make and test a mock up of the system in our Works. This test would also be of value in providing data in connection with the "power egg" proposal for aero work. We have endeavoured to obtain the maximum cooling effect for the engine in respect to the cylinders, the lubricating oil and the exhaust pipes in the space available, but the conditions of the air circulation are so novel that it is impossible to predict the result by calculation with any degree of certainty. We believe it stands however a good chance of success or we should not put it forward. The following notes describe the various features of the proposed installation:- Fan & Drive. We propose to use a fan of 28 inches diameter about 4 square feet disc area, driven by a texrope drive from the front end of the engine and enclosed in a cowling faired into the condenser shape so as to draw all the air through the condenser matrix. The belt driving pulley is mounted on ball bearings carried on a hollow tubular extension of the wheelcase and is coupled to the front end of the engine Continued. | ||
