| Abstract | Various configurations of Cell 2, with a dummy VTO fan installation, have been tested. While not giving the best possible air flow, it has been shown that a readily available configuration will give a satisfactory air flow for testing the turbofan unit. The inlet wall is left in its present condition, with its doors closed. The turbofan unit is mounted at the rear edge of the shaft from Cell 3, with its L 5'0” above the floor. The exit-end curtain wall is removed, the duct elbow is moved to one side of the stack. It is thought advisable to protect the sloping rear wall of the stack for some 12’ up, as this area will be heavily scrubbed by the exhaust. This will not be too hot, but will have an erosive effect. |
