Sealed clutch housing? That would be great fun if the crankshaft oil seal went and you didn't know about it until the housing was full of oil and the clutch started slipping .
Wouldnt have filled the housing as the oil would have been blown out of the outlet and into the engine, an even worse scenario
basically they were trying to use the flywheel as a pump to force more air into the engine
When you read some of the books writted about DB, some of the ideas they had were unbelievable. Testing the first DB aircraft tug with a torque converter gearbox for example
To test the stalling point of the hydrostat unit, a tractor was driven up to a 3ft high concrete bollard with the front wheel pressing the concrete. The torque converer had so much torque it rode the front wheel vertically up the bollard, before leaving the tractors front end wedged on top of it
they had to jack the tractor up to get it off, as the DB aircraft tugs were ballsted up to best part of 4 tonnes!!!
