This little blade is the reason

Allison’s T56 turboprop engine can deliver

22% more power and 5% better fuel economy

Allison is on target with improved turboprop power for the C-130, P-3A and E-2A

The turbine blade pictured above is hollow. Air-cooled.

By replacing solid turbine blades in Allison’s T56 Series III Turboprop, it permits higher turbine inlet temperatures and lower turbine blade temperatures.

Result: 22% more power and 5% better fuel economy – with no change in weight or envelope.

Now aircraft like the C-130, P-3A and E-2A can have greater payload, range, speed and cruise ceiling.

Now the T56 – tops in reliability among military engines flying today – is made even more reliable.

With fewer overhauls needed because engine “hot” parts last longer.

Improving superior products like the T56 is another reason why Allison’s defense, aerospace and nuclear projects are on target.
