| -5- Hw/Glb.1/EL.30.12.32. Cont'd.{John DeLooze - Company Secretary} TESTING OF CONDENSER. It was originally intended to have a double acting blow off valve fitted in the condenser but owing to the unreliability of this type of valve and the possibilities of it freezing and causing excessive back pressures it was deleted and a vent pipe is now suggested, arranged so that the possibility of freezing up is remote. CONCLUSIONS. The advantage of the finned condenser over the plain condenser is very marked but it is still to be proved how much the fins increase the drag. Arrangements are to be made to have these condensers tested in a wind tunnel and Ir. has this matter in hand. Tests are still proceeding in order to improve the system with regard to the condensate return, also the scale model tests on the rig to find out the most efficient type of fin. Ir. has consulted Hawkers with regard to the application merits etc. of this type of cooling system. Hw/T.A.Gibson. | ||
