Hermeus Receives First Pratt & Whitney F100 Engine
Hermeus has accepted its first F100 engine from Pratt & Whitney. Set to be integrated into the enhanced Chimera II turbine-based combined cycle (TBCC) propulsion system, this powerful engine component marks a critical milestone in Hermeus' development of Darkhorse.
Hermeus Selects Pratt & Whitney F100 Engine as Key Component of Hypersonic Propulsion System
Hermeus has selected the Pratt & Whitney F100 turbofan to integrate into its larger hypersonic engine. Securing an off-the-shelf turbine engine will save Hermeus billions of dollars in research and development costs and years of schedule.
Hermeus Completes Hypersonic Milestone With Engine Tests
Hermeus has demonstrated turbojet to ramjet transition within its engine, Chimera. This is one of the most important technological feats to making operational hypersonic flight a reality.
Chimera Completes Ground Testing – Heads to Hypersonic Facility for Next Tests
This test marked the final phase in our “sea-level static” testing campaign proving that we can run Chimera at full throttle on the ground.
Hermeus Wins Air Force Investment After Demonstrating Mach 5 Engine
Hermeus Corporation, the aerospace company developing Mach 5 commercial aircraft, has partnered with the U.S. Air Force and the Presidential and Executive Airlift Directorate to work toward hypersonic travel for the Department of Defense.
