GHI is vertically integrated, which means we can transition any project from conceptual design to prototype, test, and manufacturing under one roof. We are continuously evaluating and insourcing new technologies and capabilities to meet the needs of our customers and the warfighter.
As an integrator, GHI brings together comprehensive project teams with companies and researchers with specialized expertise to make any project a reality. Our partners bring cutting-edge technology and leading specialized research to complement the suite of GHI capabilities.
GHI is involved in every step of hypersonic vehicle development from the initial concept to the flight test. GHI employs multiple levels of high-fidelity tools including CAD, internal conceptual vehicle design tools, inviscid CFD, in-house developed mesh generation, viscous CFD, FEA, trajectory & stability analysis, engine performance, plus more. GHI has two in-house blowdowns and supersonic/hypersonic wind tunnels capable of supplying high-Mach flow for tens of seconds. The test facility also includes a high-temperature chamber for thermal protection system tests & vibration table for component-level qualification tests.
GHI is a thought leader in scramjet design. Our in-house research team is proactively developing next-generation concepts and models to meet the future needs of our clients. Our design team began more than ten years ago. It was driven by several US Department of Defense hypersonic technology programs, including the DARPA HyCAUSE program, DARPA ASET program, DARPA FALCON/HTV-2 program, Air Force HIFiRE 6 program, and several SBIR and STTR programs through the Air Force and Missile Defense Agency.
GHI has a growing in-house machine shop for manufacturing flight and research hardware, including two 4-axis CNC mills, a 3-axis CNC mill, two lathes, a CNC router, and a 3D printer for rapid prototyping. The facility includes tools and supplies for electrical engineering research, development, and production, including: soldering, digital oscilloscopes, waveform generators, power supplies, and more. This allows the engineers to engage with the manufacturing process and rapidly create, prototype, and test research and production parts and assemblies. In addition to in-house capabilities, GHI enjoys close collaboration with DoD teams, world-class labs, and relationships with top hypersonic subject matter experts.
GHI employs multiple levels of fidelity across different fields and tools, including CAD, internal conceptual vehicle design tools, inviscid CFD, in-house developed mesh generation, viscous CFD, FEA, trajectory and stability analysis, engine performance, and more. GHI has developed our suite of simulation software tools. LINK3D is a parallel multiblock topology-based grid generation package. High-quality, geometry-aligned grids produce better computational results and faster convergence times. While LINK3D was developed primarily for hypersonic flow applications, it has been found to perform equally well on incompressible flow and structural analysis applications.
GHI has two in-house blowdown hypersonic wind tunnels capable of supplying high-Mach flow for tens of seconds. Wind tunnel testing capabilities include sub-scale free-jet inlet, flowpath, vehicle testing, and direct-connect engine testing. The testing facility also includes a high-temperature test chamber for thermal protection system testing and a vibration table for component-level flight test qualification testing and research.
Wind tunnel testing capabilities include sub-scale free-jet inlet, flowpath, vehicle test, & direct-connect engine testing. GHI’s in-house test facilities use innovative design & operations models to deliver high-quality, cutting-edge hypersonic research at low operating costs. GHI’s two supersonic/hypersonic blowdown wind tunnels have free-jet capabilities from Mach 2.0 to Mach 6.0. Tunnel 1 is capable of unheated operation up to Mach 4.0. Tunnel 2 utilizes an electrically-powered in-line ceramic storage heater & can be operated to Mach 6 in free-jet mode or Mach 4 flight enthalpy in direct-connect mode. The entire tunnel is mounted on linear rails for direct measurement of thrust.
We look forward to adding you to the roster of other illustrious companies we have worked with to bring their projects into reality. Our company has all the proper clearances and ISO ceritifcations to ensure your project is done properly and to the highest standards.
Space in our windtunnel is limited. The sooner you know when your project will be ready for testing, the sooner you can test it and get it to market. Fill out the information below to secure the space and keep your project moving.
