Current materials which are available to designers of hypersonic seeker windows are often difficult to manufacture and made in small quantities at significant cost due to the demanding conditions encountered by these materials during hypersonic flight. High temperatures, aerodynamic pressures, and dynamic loading due to maneuvering of hypersonic vehicles produce an extreme thermomechanical environ ...

Carbon-Carbon (C-C) composites have a thermal protection systems (TPS) pedigree for next generation hypersonic flight systems due their retention of mechanical properties at temperatures exceeding 2,000°C. Continued research and development on C-C composites is required to increase the national capability, capacity, and speed of delivery for C-C composite materials. Innovative low-cost C-C compos ...

Using Combustion Research’ Flowfield Module (FM) approach, the Phase I effort laid the groundwork for the Hypersonic Vehicle Flowfield Module (HVFM) for axisymmetric/two-dimensional powered hypersonic missiles. As with all our FM tools, HVFM has an Intelligent Automated Architecture (IAA) agent which controls all aspects of the high-fidelity simulation pipeline allowing for non-experts in comput ...

For hypersonic glide vehicle (HGV) and hypersonic cruise missile (HCM) engagement scenarios intercept occurs in a flight regime where aerodynamic interaction and chemical reacting flow effects are large. To support the development of HGV and HCM intercept vehicle concepts, this program extends a current state-of-the-art hypersonic flow solver and modeling toolkit, Reentry Vehicle Flowfield 3-D Mod ...

Tungsten-based materials such as pure tungsten and tungsten-rhenium alloys are attractive hot-walled material options for solid rocket motor components, but they possess a high thermal diffusivity and can present some design challenges for thermal management. These challenges manifest themselves where geometric constraints, such as small thicknesses/volumes, coupled with long burn times and high t ...

NDT of Fracture Toughness for Pipeline Steels3/16/2018Ultrasound-based technology to nondestructively determine fracture toughness of pipeline steels will be developed. Fracture toughness is the material parameter that, along with applied loading and flaw geometry, dictates the critical crack size, and therefore controls the flaw size that must be detected during inspections. A major challenge fac ...

Tragically, 936 children have died in hot cars since 1998. Wisely, NHTSA has prioritized evaluation of sensor systems in vehicles for “the ability to detect unattended children and prevent heat stroke occurrence.”Recently, innovators have developed systems that detect children present in the vehicle by measuring carbon dioxide (CO2) in the vehicle cabin, but there is no test method to assess w ...

The goal of the proposed project is to develop an innovative advanced Electrodynamic Vertical Gradient Freeze (VEDGF) crystal growth system with superior performance, versatility, stability, and longevity to produce large single-crystal CdZnTe wafers for long-wave infrared detector arrays. The project is aiming to develop an advanced VEDGF system that offers the following performance and capabilit ...

Our unique position allows us to begin assessing models for hypersonic flow prediction on real-world systems and immediately begin to develop tools that will support acquisition, tracking, and trajectory prediction for hypersonic cruise missiles (HCMs) accomplished largely through signatures electro optical/infrared (EO/IR), radio frequency (RF), radar cross section (RCS) and acoustic. For the Pha ...

Nokomis is proposing to use Radio Frequency (RF) technology to characterize the effects of different radiation environments on electronic components. Nokomis has created and matured an ultra-sensitive RF sensor, the Advanced Diagnostics of Electronic Components (ADEC) system to characterize electronics via Electromagnetic (EM) emissions. ADEC functions as a multifaceted tool, specifically to chara ...
