Marine Inter Turbine Burner Equiped Turboshaft Engine for Combatant Craft Increased Payload

Our twin spool Inter Turbine Burner (ITB) equipped turbine engine is throttleable between 50 Hp to 700 Hp with a weight-to-power ratio (including gearbox) approaching .50 and possesses multi-fuel capability. A demonstration of this unique turbine technology, hybrid capable, marine applications is proposed. The Phase I TRL4 demonstration will include: • Demonstration that an ITB equipped turboshaft engine weighs five times less than a conventional diesel engine with comparable power and BSFC; • Investigation into technology optimization to withstand marine duty cycles and environments while retaining life performance; • Definition regarding multi-module stacking for larger applications to achieve commonality across a family of craft sizes; • Preliminary research into noise and vibration controls; • Estimates regarding mission flexibility, repair, and expeditionary land-based applications, and • Evaluation of hybrid type operations and distributed power applications. The option program defines an ITB equipped turboshaft engine optimized for implementation into advanced hull forms published in the Navy Expeditionary Combat Command Science and Technology Strategic Plan. Phase II TRL6-7 demonstration includes a marine configured ITB engine operational between 50 Hp to 1000 Hp, weight-to-power ratio (including gearbox) below .50 and BSFC less than .50. Installation into a pre-selected combatant craft will be investigated.
