Sikorsky Develops Hybrid-Electric VTOL Demonstrator for Military and Commercial Missions

Sikorsky is developing a Hybrid-Electric Demonstrator (HEX), an uncrewed VTOL aircraft with a maximum gross weight of over 7,000-pounds. The HEX will serve as a testbed for large aircraft design, novel propulsion systems, and control architectures. GE Aerospace will provide the CT7 turboshaft engine and a 1MW-class generator for the HEX project. The HEX program could lead to a family of eVTOL vehicles for both military and commercial applications.

Sikorsky, a leading provider of innovative aircraft solutions, is developing the Hybrid-Electric Demonstrator (HEX), an uncrewed VTOL aircraft with a maximum gross weight of over 7,000 pounds. The HEX project aims to serve as a testbed for large aircraft design, novel propulsion systems, and control architectures. GE Aerospace will provide the CT7 turboshaft engine and a 1MW-class generator for the HEX project GE Aerospace, Safran Aircraft Engines JV to manufacture LEAP engine components in India^[1].

The HEX program is part of Sikorsky's broader strategy to advance the development of electric vertical take-off and landing (eVTOL) aircraft. The project could potentially lead to a family of eVTOL vehicles for both military and commercial applications, aligning with the growing trend of electric aviation technologies.

The collaboration between Sikorsky and GE Aerospace is significant, as it reflects the increasing integration of hybrid-electric propulsion systems in the aerospace industry. GE's CT7 engine is a proven turboshaft engine that has been used in various military and commercial applications. The 1MW-class generator will provide the necessary power for the electric components of the HEX, demonstrating the potential of hybrid-electric systems in large aircraft.

The HEX project is also notable for its potential to contribute to the broader goals of the U.S. aerospace industry, as outlined in the White House's eVTOL Integration Pilot Program (eIPP). The eIPP aims to accelerate the integration of eVTOL operations in U.S. cities, fostering innovation and creating new transportation options. By participating in the eIPP, Sikorsky and GE Aerospace can demonstrate the safety, quietness, and scalability of their hybrid-electric technology, which are key factors in building community support for the adoption of this new technology Archer Aviation - Archer Plans For Air Taxi Trial Participation Under White House eVTOL Pilot Program With U.S. Airlines and Cities^[2].

In conclusion, the development of Sikorsky's Hybrid-Electric Demonstrator (HEX) is a significant step towards the future of VTOL aircraft. The collaboration with GE Aerospace and the potential alignment with the White House's eVTOL Integration Pilot Program position the HEX project as a key player in the evolving aerospace industry landscape.
