The anticipated benefit of ACENT's Hydrogen Wave Heater (HWH) is to allow efficient, low cost component testing for the Nuclear Thermal Propulsion (NTP) program. The NTP program requirements for high flowrate (<60 lb/s) and high temperature (<4400 F) are problematic. The HWH will not only allow these conditions to be reached, but the device has room to grow if the program requirements change in the future. Demonstration and development of a Hydrogen Wave Heater will lend itself to other applications where high-temperature, high-flowrate gases are needed. One area that has documented the need for this capability is hypersonics. The hypersonic community has identified high-enthalpy (high temperature) clean air ground test capability as an enabling technology for high speed vehicle system development. The work proposed here will lead directly to the ability to deliver continuous, high-enthalpy, clean test air that can simulate flight Mach numbers of 10 and higher. This capability, which does not currently exist, will enable the rapid development of high-speed air breathing propulsion systems by allowing representative ground testing to be performed.
