Component Function and Design--
The AAAV uses an Allison transmission for transmitting and gearing
the power from the MTU MT883 Diesel engine (rated at 2700 hp-Water Mode and 850 hp-Land
Mode) to the tracks and the water jets.
On land the AAAV has six speeds with
hydrokinetic steering and equal forward and reverse speeds.
In the water, the AAAV is propelled by two
water jet pumps with a total thrust of 22,794 Pounds Maximum
The transmission case has to have high stiffness
and low weight to minimize load distortion and meet horsepower/ weight ratio targets. |
