Bombardier JetTrain had failed to put into use
but there are still expectations for non-electrified high speed rail
plans. To confirm its possibility, design the turbine powered locomotive
with analogous performance.
The thermal efficiency of the created train is somewhat worse than that of Platt and Whitney ST40 gas turbine mounted on JetTrain. The thermal efficiency of ST40 is 33%. As the free version of notchman mini does not allow changing the efficiency, use the value as is.
The train consist is 7 passenger cars with locomotives on each end (2L7T). The output of the locomotive engine is set 3750 KW.
The created locomotive weighs 98.1 tons, about 9% heavier than original JetTrain.
To compare with DMU high speed train, 7 car consist DMU train is also created.
American passenger cars are much heavier than European DMUs and the total weight of both trains are quite different. The JetTrainlike train is nearly twice heavier than the DMU. But it has twice or more output.
The next is the performance curve of them.
The heavier JetTrainlike train has better performance in the range of almost all speed.
The route to simulate is same as the scenario 1. The running
curve well illustrates the effect of this difference.
The high acceleration and the high cruising speed enables the
short traveling time.
But the fuel consumption is dreadful.
|DMU 7M||1115.05 kg|
The JetTrainlike train consumes nearly three times as much fuel as DMU does. The thermal efficiency of real JetTrain is 5% better than this imaginary train and nearly 20% reduction will be expected. But the high output and heavy train consumes much fuel and the turbine's low efficiency spurs on this trend.
