GoHypersonic Inc. develops hypersonic technologies and advanced military systems, carrying projects from design and fabrication through ground and flight testing. The company’s work centers on propulsion-airframe integration and ramjet and scramjet engine development, supported by more than a decade of vehicle and engine design experience, an in-house machine shop, and two hypersonic wind tunnels. Based in partnership with aerospace R&D laboratories, OEMs, and the Department of Defense, GHI turns its research into tested flight hardware and operational systems.
North Wind USA IncNorth Wind USA Inc. designs and manufactures mission-critical aerospace systems while operating aerodynamic and hypersonic test facilities for government and industrial customers. Its FluiDyne Aerotest Laboratory in Plymouth, Minnesota, has provided wind-tunnel testing and developmental hardware since 1952, and the company’s heritage includes a hypersonic tunnel capable of reaching Mach 14. Formed in 2024 from Calspan ASE and Calspan Systems, North Wind also played a technical design role in NASA’s new Flight Dynamics Research Facility.ARLINGTON, VA
Ahmic AerospaceFounded in Dayton in 2014, Ahmic Aerospace develops high-performance measurement instrumentation and conducts research for aerospace testing, with roots in high-accuracy wall shear sensors. Its in-house supersonic wind tunnel, shock tube and hot-jet facilities support sensor design, calibration and studies of complex flow physics, including hypersonic applications. Ahmic is ISO 9001:2015 certified and an ITAR-registered manufacturer.OAKWOOD, OH
VelontraVelontra is a Cincinnati aerospace company built around rapid, risk-tolerant development rather than the slow pace it sees in much of today’s industry. It develops jet propulsion for defense and other advanced aerospace applications, using repeated design-build-test cycles to shorten development time and reduce cost.LEBANON, OH
HAMR Industries LLCHAMR Industries was founded by materials scientists Dr. Michael Schmitt and Dr. Jeremy Schreiber to move breakthrough research into practical use. The Pittsburgh-area company has grown from a basement startup into a bootstrapped contract manufacturer and research provider, known for applying cold spray additive manufacturing to components built for harsh environments. Its work serves aerospace and defense customers, including a hypersonic vehicle component that became the first free-form cold-spray part flown on such a vehicle.CLINTON, PA
