The United States is understood to have begun the process of preparing its helicopter fleets for the new and more powerful Improved Turbine Engine Program (ITEP), due to enter service in the coming years.

The Department of Defense (DoD) posted a solicitation on its beta.sam.gov website on 13 December for the upgrade of the tailrotor drivetrain of the Boeing AH-64E Apache Guardian attack helicopter. This is believed to be in anticipation of a retrofit of the ITEP engine that will increase its current 2,000 shaft horsepower (shp) engines with one that puts out 3,000 shp.

The Tail Rotor Drive Systems (TRDS) redesign effort seeks to improve the helicopter’s tail rotor performance by designing it to handle an increased torque load. The proposed design will be no more than a 10% increased weight over the legacy design, must meet or exceed the Mean Time Between Failure (MTBF) imposed on the current design, not require airframe modifications, and be ready for flight testing in the second quarter of fiscal year (FY) 2022.
