GE Aviation has submitted a technical proposal for the Improved Turbine Engine Program (ITEP), which is a US Army project to re-engine Boeing AH-64 Apache and Sikorsky UH-60 Black Hawk helicopters.

The company intends to offer T901-GE-900 engine for the ITEP and the technical proposal is the second and final phase of its Engineering and Manufacturing Development (EMD) proposal to the army.

GE submitted its first phase of the proposal in February this year.

Last month, the US Army and GE successfully completed their preliminary design review (PDR) approving the company’s design and configuration of the T901 engine.

In September 2016, the army awarded GE a $102m, 24-month Technology Maturation and Risk Reduction (TMRR) contract.

GE T901 Programme executive director Ron Hutter said: “Using GE’s industry leading technologies, rather than mechanical complexity, to meet ITEP requirements enables the use of a single-spool design, making the T901 engine less complex, less expensive, and a lighter weight.

“The T901’s single-spool core enables full modularity, building on the success of the combat proven T700 and providing the Army superior fix-forward maintainability, reduced lifecycle costs and improved warfighter readiness.”

“GE submitted its first phase of the proposal in February this year.”

The US Army Contracting Command (ACC) is expected to select one engine manufacturer for the EMD phase by the end of this year.

To date, the company has invested more than $9bn in maturing technologies applicable to the T901 engine and more than $300m for the development and testing of turboshaft-specific technologies.

Integrated with advanced technologies, the GE engine will help advance Army Aviation into the future of vertical lift.

The company uses 3D printing technology to create advanced, cost-effective T901 parts with shorter development time that reduce fuel burn, decrease weight and increase durability.

The engine is also incorporated with ceramic matrix composite (CMC) components which are lighter and more durable than metal parts and have the capability to withstand higher temperatures.

The turboshaft design, manufacturing, assembly and testing on the T901 will be carried out at Lynn, Massachusetts; Huntsville, Alabama; Newark, Delaware; Jacksonville, Florida; Madisonville, Kentucky; Muskegon, Michigan; Hookset, New Hampshire; Asheville, North Carolina; West Chester and Evendale, Ohio; and Rutland, Vermont.
