Hermeus is Rapidly Iterating to Quickly Develop Hypersonic Aircraft

Hermeus completed testing of their full system hypersonic ground Mk0 test plane. It is a complete system made in 6 months and tested in 37 days. The fully-integrated vehicle, Quarterhorse Mk 0 is a non-flying prototype acted as a ‘dynamic iron bird’ for the company by validating all major aircraft subsystems in a real-world environment. It has been one year since the Hermeus had a ground test of their Chimera engine transitioning from turbojet to ramjet power. They need to build the successive airframes to hold their engines to reach hypersonic speeds.

Hermeus is a new defense company but they have a multi-year Defense Intelligence Unit contract that will fund them through the financial valley of death.

The Defense Innovation Unit (DIU) contract is to mature Hermeus hypersonic aircraft subsystem and mission system technology. Hermeus will utilize its commercial high-speed flight test prototype, Quarterhorse, to support technical maturation and risk reduction for future hypersonic aircraft. The contract is part of DIU’s Hypersonic and High-Cadence Airborne Testing Capabilities (HyCAT) initiative, which aims to utilize commercial flight test capabilities to expand the Department of Defense’s high-speed flight test capacity.

The multi-year award will feature Hermeus’ iterative approach to technology maturation and aircraft development. Through this contract, Hermeus will demonstrate key enabling technologies for hypersonic aircraft in relevant environments preparing them for introduction into future programs. These technologies include propulsion and propulsion integration; thermal management; power generation; and hypersonic mission system capabilities. This effort will transition the world’s fastest aircraft to an operational flight test capability for hypersonic capability experimentation, and validation.

Hermeus aims to develop hypersonic aircraft quickly and cost-effectively by integrating hardware-rich, iterative development with modern computing and autonomy. This approach has been validated through design, build, and test of the company’s first combined turbojet-ramjet engine and is now being scaled through its first flight vehicle program, Quarterhorse. Hermeus is also developing Darkhorse — an uncrewed hypersonic aircraft designed to deliver unique asymmetric capabilities to the warfighter.
