Is M1 Abrams power pack available?


The next is to demonstrate the effects of the recuperator AGT1500 has.
Start notch man mini and design the turbine powered railcar equipped with 1500 horse power class power pack. This time enable the recuperation. The default thermal efficiency improves to 31.2 %, slightly better than that of AGT1500. As the free version of notchman mini cannot modify this by users, use this default value as is.

Other settings are just same as those set at the previous page.

The simulated total operating time is here. It takes a few tens of seconds longer than previously simulated turbo trains. This is due to the increase of the train mass caused by adding the recuperator.

The fuel consumption is dramatically reduced.
The next table is the comparison of the fuel consumption between non-recuperated and recuperated.

Consist non-recuperated recuperated
2M4T 1676.30 kg 1232.36 kg
3M3T 2291.50 kg 1399.42 kg
4M2T 2512.73 kg 1556.47 kg

But the DMU consumes  only 1101.54 kg in the same section and the turbo train(2) that operates this route almost in same time consumes about 27 % much fuel.
This result is far better than that of "M1A1 Abrams turbine tank versus Leopard 2 diesel tank". This is due to the difference of the operating pattern between the tank and the semi-high speed train. The next shows the percentage of the engine output used during this operation.

In the semi-high speed train operation, 100 % output or 0 % output is mostly used. Trains can coast long distance but tanks cannot. So that tanks must use fuels while reducing speed gradually and the time engines run at the partial load is far longer than trains.
