Pressure gain combustion (PGC), such as in a rotating detonation engine (RDE), has the potential to increase combustor efficiency up to 10%. This improvement would be valuable to many DoD systems such as thrusters, engines, and power generation units. In an earlier AFRL funded Phase I effort, GTL designed and modeled conceptual liquid injection rotating detonation engine concepts.  By the end of ...

A dual/company team, SPEAR LLC and HEAR LLC, with deep R&D experience in hearing protection devices (HPD) and successful DoD contract and SBIR accomplishment, has evidenced strong feasibility for all required subsystems of SOCOM “Canine In/Ear Hearing Protection.” The centerpiece of the team’s ‘K9HPD’ is a dynamic membrane earplug, that unlike expandable foam, flanged/polymer, and custom ...

We will develop a comprehensive approach to find RF-based side channels in complex heterogenous circuits, devise methods using active excitation to pull challenging signals out where passive mechanisms are infeasible and determine internal modes of operation in the target platform.  The system will make use of multiple advanced RF simulation techniques to predict the optimum side channel attacks ...

The battlefield of the future and today, is based on data; and the ability to act upon this data. Data provides the foundation of everything from intelligence, situational awareness, and force readiness. Acquiring data in extreme environments requires analog and mixed signal electronics that don’t need thermal management. Integrated circuits (ICs) made with silicon carbide (SiC) semiconductor te ...

Hypersonic vehicles and weapons systems offer the ability to quickly strike across the globe and are essential for the future of the U.S. armed forces. Operating these systems at hypersonic speeds presents new engineering challenges. Specifically, control system and sensor technologies used on conventional aircraft are not adequate for hypersonic environments where surface temperatures can reach u ...

Robust instrumentation for advanced engine development in both the near and long term is required to maintain the air superiority of the United States Air Force.  This robust instrumentation must withstand the high-temperature and vibration environments present not only in existing high-speed propulsion systems but also future propulsion systems that will operate in hypersonic envelopes. Instrume ...

In this effort, GTL proposes to develop sensors for a high-temperature instrumentation system for hypersonic vehicles and scramjet propulsion systems. These sensors will be based on GTL’s Structural Nervous System™ (SNS™) and CNTOR™ technologies. GTL and its partner NFA will leverage a suite of internally developed modeling tools including multi-physics codes, coupled thermo-acoustic codes ...

Over the past decade, GTL has developed a suite of transformational technologies that provide superior performance for reduced cost.Each of these technologies have been matured to TRL 6 and establish the technical foundation for the Advanced Cryogenic Expendable (ACE) Multi-Role Vehicle (ACE-MRV). The ACE-MRV is a high-performance expendable rocket stage that can either be launched (from the groun ...

In a previous effort, GTL successfully demonstrated that the BHL cryotank technology provides a 75% mass reduction compared to the state of the art cryotanks. This capability would double the payload a liquid propellant launch vehicle just from the mass...
